A.2.    CRUISE SUMMARY

A.2.a.  Cruise Track

R/V Thomas Washington departed San Diego on May 31, 1991 and occupied a test 
station north of Pt. Conception with the main purpose of testing the heave 
compensator. After the test station, the ship stopped at Port San Luis to 
exchange personnel and immediately proceeded northward to Station 1 at 36°10'N, 
121°44'W, where it turned to the southwest to make a line of stations roughly 
normal to the coast as far offshore as 34°35'N, 125°09'W (Station 9). From 
Station 9, the cruise track ran due west to 135°W (Station 17) and then turned 
to the south along 135°W. It extended southward across the equator, and the last 
station was occupied at 6°S, 135°W (Station 123). Near the equator, the track 
was shifted to the west by 10 nm to avoid a seamount. Thomas Washington arrived 
in Papeete, Tahiti on July 11.

The stations were spaced at intervals of 30 nm except near the California coast 
and the equator, where closer spacing was employed to resolve small-scale 
features. Along 34°35'N, however, the time constraint due to bad weather 
necessitated coarser spacing (see 4 below). The station locations are shown in 
Fig. 1.

A.2.b.  Sampling

Sampling was done primarily with use of a 36-place 10-liter bottle rosette. 
Water samples were collected for analyses of salt, oxygen, silicate, phosphate, 
nitrate, and nitrite on all stations and of CFC-11, CFC-12, 3helium, tritium, 
AMS 14C, alkalinity, and total dissolved inorganic carbon on selected stations. 
A smaller rosette with 11 bottles equipped with an ADCP was also used on 
alternate stations between 3°N and 3°S, where station spacing was 10 nm, but 
water sampling was limited to salt to calibrate the CTD. Large-volume sampling 
was made with use of 270-liter Gerard barrels for analyses of 14C, salt, and 
silicate on 9 stations spaced at intervals of about 50 of latitude along 135°W.

Separate surface water samples were also taken on 37 stations for analyses of 
226Ra, 228Ra, and Ba.

In addition to the on-station measurements mentioned above, a shipboard ADCP was 
continuously operated along the entire cruise track.

A.2.c.  The Number of Stations and Station Type

A total of 123 stations were occupied during the cruise. Of these, 104 were 
regular CTD/rosette stations, and 19 were ADCP/CTD stations within 30 of the 
equator without water sampling (except for salt samples for CTD calibration). On 
9 of the former, Gerard casts were also made for large-volume water sampling.


A.2.d.  Floats and Drifters Deployed

Eleven ALACE floats were deployed at 11 locations along 135°W, and 4 surface 
drifters were deployed at 4 locations near the equator and 135°W.

A.4  Scientific Programme and Methods

Some of the preliminary results from this cruise are briefly described below:

1)  There was an indication of strong upwelling in a narrow strip within 30 km 
    of the California coast. Isopleths of all properties rose toward the shore, 
    and cold, low-oxygen, high-nutrient water apparently upwelled from a depth 
    of about 100 m was observed at the sea surface within this coastal strip. 
    However, the isopycnals (isotherms) below about 150 m deepened toward the 
    coast and suggested the presence of the poleward California Undercurrent.
2)  The highest surface temperature exceeding 28°C was observed between 12°N and 
    2.5°N. Farther south the sea-surface temperature decreased gradually but 
    remained above 27°C all the way to the southern end (6°S) of the section. 
    This surface temperature in the equatorial region is at least 1°C higher 
    than the normal temperature for July.
3)  The North Equatorial Countercurrent was clearly indicated by the equatorward 
    deepening of the thermocline from 8°N to 5°N. Farther south, an equatorward 
    dip of the 9-12°C isotherms suggested that the subsurface North Equatorial 
    Countercurrent was well developed. The Equatorial Undercurrent was indicated 
    by a trough of the isotherms in the lower portion of the thermocline at the 
    equator, but there was no evidence of a ridge of the isotherms in the upper 
    portion of the thermocline. The Undercurrent was also associated with an 
    isolated core of high salinity centered at 100 m, 1°S and an isolated core 
    of high oxygen centered at 140 m on the equator. A weak indication of the 
    subsurface South Equatorial Countercurrent was found at 200-400 m near 
    4°30'S in the temperature distribution.
4)  The coldest and densest bottom water (theta=1.006°C, sigma 4=45.900, 
    S=34.695) over the entire section was observed at 18°30'N about 200 km north 
    of the Clarion Fracture Zone. This water was high in salinity and oxygen and 
    low in nutrients and suggested an eastward flow of the bottom water from the 
    Central Pacific Basin. The saltiest (S=34.698) bottom water, also highest in 
    oxygen (O2=4.03 ml/l), was located near 4 S somewhat south of the Galapagos 
    Fracture Zone. Relatively cold, salty, oxygen-rich, nutrient-poor bottom 
    waters were also found at 24 N in the Molokai Fracture Zone and at 6 30'N in 
    the Cilpperton Fracture Zone. On the other hand, the bottom water within 
    about 30 of the equator was relatively warm, low in density and oxygen, and 
    high in nutrients. These meridional differences in the bottom water 
    characteristics may be due in part to the differences in the bottom depth 
    but in greater part appear to reflect the zonal flow pattern of the bottom 
    water.
5)  The vertical maximum of silicate, which is the major feature of the silicate 
    distribution in the Pacific Ocean, was observed at about 3000 m throughout 
    the present section. However, many (but not all) stations between 3°N and 
    3°S exhibited a weak minimum at about 3000 m, thus producing maxima at 2500 
    m and 3500 m. This double maximum structure of the silicate distribution 
    near the equator appears to be a real feature, but its cause and relation to 
    the circulation are not immediately obvious.


A.5  Major Problems Encountered on the Cruise

During the first week of the cruise, the bad weather that prevailed over the 
operation area made the handling of the CTD/rosette package difficult and slow. 
Because of the heavy rolling of the ship, the rosette could not be set up for a 
cast while underway and could be lowered only at a speed of 15-30 m/min. To 
avoid falling seriously behind schedule, it was necessary to increase the 
station spacing along 34°35'N (Stations 9-17) to 60 nm. Thus the WOCE 
specification of the 30 nm station spacing could not be met for this portion of 
the section.

The bad weather also was the main cause of a large number of bottle problems on 
stations 1-34, including bad trips, kinked wire, broken bottles and stopcocks.

B.   Underway Measurements 

B.1  Navigation

B.2  Acoustic Doppler Current Profiler (ADCP)

The ADCP that was run during this leg was an RD-VM150 153-kHz unit manufactured 
by RD Instruments and owned by Scripps. Raw data were logged on a PC and 
simultaneously on a SUN workstation. Position fixes provided by a Magnavox 4200 
GPS receiver were logged at the endof each 5-minute averaging interval 
("ensemble") on the PC, and at a 1-Hz rate on the SUN. The shipe's gyrocompass 
heading was input to the ADCP via a 1:1 synchro, and used for vector-averaging 
the velocity profiles in geographical coordinates. Heading error was calculated 
after the cruise from raw GPS data logged at 1 Hz from each of 2 Magnavox 4200D 
receivers, together witht he gyrocompass heading. These error calculations were 
crude and gappy, but did provide useful information that was used in 
postprocessing. The ADCP itself performed well apart from frequent failures 
during the first half of the cruise caused by ship's power glitches. The typical 
ADCP depth range was 300-400m.

The ADCP data have been processed using the Uniersity of Hawaii CODAS software 
package, as outlined in teh WHP Operations and Methods Manual. Processed data 
are archived on tampe in CODAS format at UH. Requests may be addressed to Eric 
Firing (efiring@soest.hawaii.edu: 808-956-7894)

B.3  Meterological Observations

Meterological observations where taken at each station. Information taken at 
each station included dominant wave direction, wind speed and direction, 
atmosperhic pressure, air temperature, weather, clouds and visiblity.


C.   Hydrographic Measurements

C.1    Description of Measurement Techniques and Calibrations

Extensive comments regarding calibration of both CTDs will be forthcoming from 
ODF. Sections B.1.1 and B.1.2, on the CTD data collection and processing, are 
incomplete, premature and possibly inaccurate and are based on notes taken by 
L.Talley during discussion with M. Johnson, the ODF CTD data processor. Discrete 
sample analysis text was supplied by ODF. The Oceanographic Data Facility's 
listing of bottle data comments which is included as section D could be of as 
much use to the DQEs as it was to us. Sections concerning the other measurements 
should be obtained from the relevant principal investigators.

C.1.a  CTD   (Lynne Talley)

Two NBIS Mark III CTDs were used. The first, designated CTD#1, was used for all 
stations except the alternate 10 nm stations between 3 N and 3 S. Because of the 
small station spacing in this zone, the length of time required to draw water 
from the 36-bottle rosette, and the perceived lack of need for water samples at 
10 nm resolution except for calibration of the CTD, the 36- bottle rosette with 
CTD#1 was alternated with a 12-bottle rosette with CTD#2. Only 11 bottles were 
used on the second rosette in order for a lowered ADCP to be attached to the 
rosette frame.

C.1.1  CTD#1

Temperature: two PRT's were mounted on the CTD. PRT1 was used for the 
temperature data throughout; PRT2 was available to use to check for drift, but 
this was not actually done. The pre-cruise calibration was 0.0028 C and 0.0023 C 
warmer (for warm and cold ends of the calibration, respectively) than the post-
cruise calibration but it was determined that the drift was not systematic and 
an average calibration was used. Temperature accuracy is therefore (0.0014 C to 
0.0011 C).

PRESSURE: 
One sensor was used throughout. There was a 3 dbar shift from pre to post-cruise 
calibration with no change in slope, so the difference is probably due only to 
initial offset in pressure. This is corrected for during calibration of each 
station, using the initial pressure. Pressure precision is 0.5 dbar after the 
pressure offset is removed according to the pressure model. In oceanic 
conditions, with changing temperature, the pressure error is smaller than 5 
dbar.

CONDUCTIVITY: 
There was no significant change in slope of conductivity as a function of delta 
C (difference between bottle and CTD conductivity), so one slope was applied to 
the whole cruise. There were four groups chosen for offsets:

Stas. 3-8: constant offset, ignoring stations 1,2,6
Stas. 9-30: sloping offset as function of stations, ignoring station 18
Stas. 31-67: constant offset
Stas. 68-123: constant offset

The data were very clean after station 30.

In looking at the data recently, we noted that there is a problem with an 0.001 
to 0.002 psu shift on many stations, at about 1.3-1.4 C (potential temperature). 
Stations which appear to have this after station 30 are: 31, 32, 33, 34, 35, 
(36,37), 39, 40, 42, 43, 45, 46, 47, 48, 49, 52, 54, (63??), 76, (78?), 80, 84, 
86, 88, 90, 92, 94, 98, 102, (118?), (123?). ODF is currently looking at these 
as part of the final documentation phase.

There are also some remaining bulges and spikes which might not be real: sta. 50 
(2638 dbar), 71 (3986 dbar).

C.1.2. CTD#2

CTD#2 was used on the 18 stations with odd numbers stating at 81 and ending at 
117. Bottle data to calibrate the casts was quite scanty; in retrospect we would 
advise concentrating more bottles in the lower 2000 meters, rather than on 
attempting to get a full profile. No water was collected from the bottles for 
any purpose other than conductivity calibration. Because the rosette 
configuration was new (owing to the use of the LADCP), there were many tripping 
problems caused by fouled lanyards at the start of the group of stations, so the 
number of calibration points is quite small at the outset.

TEMPERATURE: 
both PRT1 and PRT2 shifted at some point between pre-cruise calibration and 
station 183 on the next leg; the problem was first recognized during the 
following leg on which CTD#2 was used more extensively. (I'm not actually sure 
that this statement is correct - LDT.) At station 183, thermometers were added 
to the casts and thereafter helped in sorting out the problems enormously. It 
was then assumed that all of the PRT2 shift occurred after leg 1 and that there 
was also a shift in PRT1 between legs. The pre- cruise calibration was applied 
to PRT1 for the leg 1 data.

Pressure: 
the post-cruise calibration was 8 dbar lower than the pre-cruise CALIBRATION. 
There was only a 2 dbar offset during the cruise, so only the pre-cruise 
calibration was used. (I'm not clear about how this was known or decided.)

CONDUCTIVITY:
A slope which decreased as a function of station number was applied. Offsets 
were chosed using stations 99-117 and then extrapolated back. Fairly large 
individual station offsets were applied to several stations. Conductivity was 
somewhat noisy and there appears to have been a maintenance problem. The 
salinity offset problem on CTD#1 was not at all apparent on CTD#2, and this is 
the main reason for concluding that there was a sensor problem with CTD#1.

C.1.3. Comparison of CTD#1 and CTD#2 data:

Plots of salinity on isotherms and isopycnals shows a significant offset between 
CTD#1 and CTD#2, which is of the order of 0.001 psu at the cast bottom, and 
increases to 0.002 psu at about 2000 meters. CTD#1 is fresher than CTD#2 
throughout. Most of the change in offset occurs at the point where CTD#1 
conductivity has an offset of its own.

Because of the very low vertical gradients of salinity in the deep water, the 
consistent offset between CTD#1 and CTD#2 is easily apparent in a vertical 
section. Vertical sections of potential temperature and potential density are 
not affected.

Statistical differences between CTD#1 and CTD#2 salinities were estimated with

(1) differences in average salinity and pressure on isotherms for the station 
    range 80-118: CTD#1 is .001 to .003psu fresher than CTD#2 for temperatures 
    1.0 to 2.0 C, with the higher difference at 2.0 C.

(2) differences in average salinity, theta and pressure on isopycnals for the 
    station range 80-118: CTD#1 is 0.0008 to 0.002psu fresher than CTD#2 for the 
    isopycnal range 45.88 to 45.7 sigma 4, with the smaller differences at 
    higher density.

(3) average differences in adjacent stations' salinity and theta on isopycnals 
    45.88, 45.80 and 45.70 sigma 4: the results are very similar to (2), with 
    CTD#1 0.0008 to 0.002 psu fresher than CTD#1, with the smaller differences 
    at higher density. The difference in theta on these isopycnals is 0.003 to 
    0.008 C, with the higher difference at lower density.

Given that there is a systematic offset in salinity between CTD#1 and CTD#2 of 
0.001 to 0.002 psu below 2000 dbars, what is the effect on geostrophic velocity 
calculations? Using one station, dynamic height was computed at the surface 
relative to 4000 dbar with the original salinities, and then adding the same 
salinity offset to all bottles.

Adding 0.002 psu (i.e. higher salinity) increases the density, decreases the 
specific volume anomaly, and hence yields lower dynamic height, by 0.013 dynamic 
meters at the surface relative to 4000 dbar. The change is nearly linear in 
salinity error, so a 0.001 psu error would create half the dynamic height error. 
If geostrophic velocities are then calculated using the original station and the 
altered station, using various station spacings and latitudes, we can produce a 
table of velocity errors as a function of salinity error, station spacing and 
latitude.

For.002deltaS,the velocity error is (incm/sec):

                          1N  5N  10N  20N  30N   40N
                         ---  --  ---  ---  ----  ---
                  60 nm   20   4    2    1  .7     .6
                  30 nm   40   8    4    2   1.4  1.2
                  20 nm   60  12    6    3   2.1  1.8
                  10 nm  123  25   12    6   4.3  1.7


The result is of course exactly inversely proportional to station spacing. It is 
also nearly linear in delta S.

On transport errors: an error of 1 cm/sec over 1000m over 10nm (18.5 km) is 
equivalent to 0.185 Sv and a 100 cm/sec error therefore is equivalent to an 18.5 
Sv error.


C.2. BOTTLE DATA COLLECTION, ANALYSES, AND PROCESSING

Chief scientist comments: Bottle quality and data quality flags were first 
assigned by ODF and then examined by the chief scientists. After several 
iterations, we arrived at the set which are being sent with this documentation. 
We note that selection of quality flags posed some difficulties. In particular, 
there is no way to note that comments that there might have been a leak but 
where salinity, oxygen and nutrient values all appear to be fine; noting the 
potential problem could be important for the other analyses. The distinction 
between data quality which is questionable (flag = 3) and which is bad (flag = 
4) is also difficult in practice. Generally it was assumed with this data set 
that "bad" means that there was a fault noted with the actual analysis, and 
"questionable" means that the value is bad but no fault was noted with the 
actual analysis.

We, the chief scientists, strongly urge any users of this data to discard ANY 
value with a bottle data quality flag of 3, and any data quality flag of either 
3 or 4. "Questionable" data, flagged "3" does not mean "potentially good", 
rather it means bad but for unknown reasons. This comment is meant to clarify 
the comment in the ODF documentation which says that it is up to the scientists 
to decide whether to use data flagged as 3. When the level 2 data product is 
written and archived, no data with flags of either 3 or 4 should be archived. 
All bottle salts with these flags should be replaced with the CTD salts.

1.  Introduction

In this document we discuss CTDO data acquisition, calibration,corrections, and 
other processing for the TUNES cruise, Legs 1 and 2,on the R/V Thomas 
Washington.  At various times during these legs, theCTD instruments and sensors 
exhibited more than the usual share ofnoise, drifts or other problems, making 
CTD data processing morechallenging than usual.  We believe that we have greatly 
reduced theuncertainty in the final reported values via careful examination 
andapplication of the pre- and post-cruise calibrations, and bycomparison of CTD 
data with the water sample and thermometric datacollected during the CTD casts.  
Our techniques and calibration dataare discussed below.

2.  CTD Acquisition and Processing Summary

221 CTD casts and 4 test casts were completed during TUNES Legs 1and 2.  The 
rosette used was an ODF-designed 36-bottle system with aring of twelve 10-liter 
bottles and 12- and 24-place General Oceanicspylons nested inside a ring of 
twenty-four 10-liter bottles.  A CTD,altimeter, pinger and transmissometer were 
mounted on the bottom ofthe frame.  ODF CTDs #1 and #2 (modified NBIS Mark III-B 
instruments)were used during both Legs 1 and 2.  CTD #10 was used on Leg 2 only.

Each ODF CTD acquired data at a maximum rate of 25 Hz.  The dataconsisted of 
pressure, temperature, conductivity, dissolved oxygen,second temperature, four 
CTD voltages, trip confirmation,transmissometer, altimeter and elapsed time.  
Power to the CTD wasoptimized by applying the minimum current to attain the CTD 
voltagesrequired to maintain sensor stability.  These voltages were 
monitoredthroughout the cast.

An ODF-designed deck unit demodulated the FSK CTD signal to anRS-232 interface.  
The raw CTD data server allowed the data to besplit into three different paths: 
to be logged in raw digitized form,to be monitored in real time as raw data, and 
to be processed andplotted.  During the TUNES expedition, an Integrated 
Solutions Inc.(ISI) Optimum V computer served as the real-time data acquisition
processor.  Additionally, Sun SPARC computers were used during post-cruise 
processing.

The raw CTD audio signal was recorded on VHS videotape as anultimate back-up, 
and all raw binary data were logged on a hard diskand then backed up to magnetic 
cartridge tape.  In addition, allintermediate versions of processed data were 
backed up to magneticcartridge tape.

CTD data processing consists of a sequence of steps which ismodified as needed.  
Data can be re-processed from any point in thissequence after the raw data are 
acquired from the sea cable andrecorded on videotape and/or hard disk.  Each CTD 
cast is assigned acorrection file, and while the corrections are usually 
determined forgroups of stations, it is possible to fine tune the parameters 
foreven a single station.  The acquisition and processing steps are asfollows:

 Data are acquired from the CTD sea cable and assembled into consecutive 
  .04-second frames containing all data channels.  The data are converted to 
  engineering units.
 The  raw  pressure,  temperature and conductivity data are passed through 
  broad absolute value and gradient  filters to eliminate noisy  data. 
  The entire frame of raw data is omitted, as opposed to interpolating bad 
  points, if any one of the filters is exceeded.  The filters may be 
  adjusted as needed for each cast.

                       TYPICAL TUNES RAW DATA FILTERS
       
                Raw Data    |       |       |Frame-to-Frame
                Channel     |Minimum|Maximum|   Gradient   
                ------------|-------|-------|--------------
                Pressure    |  -40  | 6400  |   2.0 dbar   
                ------------|-------|-------|--------------
                Temperature |  -8   | 32.7  |.2 to .6 deg.C
                ------------|-------|-------|--------------
                Conductivity|   0   |64.355 |.3 to .6 mmho 


 Pressure and conductivity are phase-adjusted to match the temperature 
  response, since the temperature sensor responds more slowly to change. 
  Conductivity data are corrected for ceramic compressibility in accordance 
  with the NBIS Mark III-B Reference Manual.
 The data are averaged into 0.5-second blocks.  During this step, data 
  falling outside four standard deviations from the mean are rejected and 
  the average is recalculated.  Then data falling outside two standard 
  deviations from the new mean are rejected, and the data are re-averaged. 
  The resulting averages, minus second temperature and CTD voltages, are 
  reported as the 0.5-second time series.  Secondary temperature data are 
  used to verify the stability of the primary temperature channel 
  calibration.  Secondary temperature data are only filtered, averaged and 
  reported with the time-series data when they are used in place of the 
  primary temperature data due to a sensor malfunction.
 Corrections are applied to the data.  The pressure data are corrected 
  using laboratory calibration data.  Temperature corrections, typically a 
  quadratic correction as a function of temperature, are based on laboratory 
  calibrations.  Conductivity and oxygen corrections are derived from water 
  sample data. Conductivity corrections are typically a linear fit as a 
  function of conductivity.  Oxygen data are corrected on an individual cast
  basis using the technique.  Uncorrected time-series transmissometer data are 
  forwarded to TAMU for final processing and reporting.

The averaged data are recorded on hard disk and sent to the real-time display 
system, where the averaged data can be reported andplotted during a cast.  The 
averaging system also communicates withthe CTD acquisition computer for 
detection of bottle trips, almostalways occurring during the up casts.  A 3- to 
4-second average of theCTD data is stored for each detected bottle trip.

A down-cast pressure-series data set is created from the timeseries by applying 
a ship-roll filter to the down-cast time-seriesdata, then averaging the data 
within 2-dbar pressure intervalscentered on the reported pressure.  The first 
few seconds of data foreach cast are generally excluded from the averages due to 
sensoradjustment or bubbles during the in-water transition.  Pressureintervals 
with no time-series data can optionally be filled by double-parabolic 
interpolation.  When the down-cast CTD data have excessivenoise, gaps or 
offsets, the up-cast data are used instead.  CTD datafrom down and up casts are 
not mixed together in the pressure-seriesdata because they do not represent 
identical water columns (due toship movement, wire angles, etc.).

The CTD time series is always the primary CTD data record for thepressure,  
conductivity  and  temperature channels.  The final correc-tions to the CTD 
oxygen data are made  by  correcting  pressure-seriesCTD  oxygen  data  to match 
the up-cast oxygen water samples at commonisopycnals.  The final CTDO pressure-
series data are the data reportedto the principal investigator and to the WHP 
Office.

Subsequent sections of this document discuss the laboratorycalibrations, data 
processing and corrections for each CTD used duringTUNES Legs 1 and 2.


3.    CTD Laboratory Calibrations

3.1.  Pressure Transducer Calibration

Each CTD pressure transducer was calibrated in a temperature-controlled bath to 
the ODF Ruska deadweight-tester (DWT) pressurestandards.  The mechanical 
hysteresis loading and unloading curveswere measured both pre- and post-cruise 
at cold temperature (-1.0 to0.1 degrees C bath) to a maximum of 8830 psi, and at 
warm temperature(29.4-30.2 degrees C bath) to a maximum of 1730-2030 psi.  The 
CTD-1pre-cruise calibration also included a cold calibration to 2030 psi aswell 
as a warm calibration to 8830 psi.

CTD #10 was not calibrated post-cruise because it flooded duringLeg 2 and was 
modified during repair.  CTD #1 and CTD #2 had partsinterchanged during Leg 2; 
these were put back in their originalconfigurations before their post-cruise 
calibrations.

CTD pre- and post-cruise pressure calibrations are summarized inFigures 1, 2 and 3.

3.2.  PRT Temperature Calibration

All CTD PRT temperature transducers were calibrated in atemperature-controlled 
bath.  CTD temperatures were compared withtemperatures calculated from the 
resistance of a standard platinumresistance thermometer (SPRT) as measured by a 
NBIS ATB-1250resistance bridge.  The ultimate temperature standards at ODF 
arewater and diphenyl ether triple-point cells and a gallium cell.  Sixor more 
calibration temperatures, spaced across the range of -2.0 to30.2 degrees C, were 
measured both pre- and post-cruise.

CTD pre- and post-cruise temperature calibrations are summarized in Figures 4, 5 and 6.


4.    CTD Data Processing

4.1.  Pressure, Temperature and Conductivity/Salinity Corrections

A maximum of 36 salinity and oxygen check samples were collectedduring each CTD 
cast.  Thermometric temperature data were alsomeasured at 1 or 2 levels per cast 
for stations 183 through 220 on Leg2.  No thermometric pressure data were 
collected.

A 3- to 4-second average of the CTD time-series data wascalculated for each 
sample.  The resulting data were then used toverify the pre- and post-cruise 
temperature calibrations, and toderive CTD conductivity/salinity and oxygen 
corrections.

Two CTDs were traded off during the equatorial section of Leg 1so that 11-bottle 
rosette casts with LADCP could alternate with36-bottle rosette casts.  During 
Leg 2, there were numerous CTDproblems and repair attempts that resulted in 
various sensors andinterfaces being shifted from one instrument to another.  
Thefollowing chart clarifies which sensors were being used for any givencast on 
Leg 1 or Leg 2:

4.1.1.    CTD Pressure Corrections

4.1.1.1.  CTD #1

CTD #1 pre- and post-cruise pressure calibrations, Figures 1a/band 1c, were 
compared.  The warm/shallow and cold/deep calibrationcurves both shifted by 
about 3 decibars from pre- to post-cruise.  Theslopes of the warm/shallow 
pressure calibration curves were nearlyidentical.  The slopes of the cold/deep 
curves were slightlydifferent:  shallower points were 1 decibar closer than 
deeper pointsfrom the two calibrations.  Thermometric pressures were not 
measuredduring either leg.

An average of the pre- and post-cruise pressure calibrations,Figure 1d, was 
calculated and applied to the CTD #1 pressure data fromboth legs.

4.1.1.2.  CTD #2

CTD #2 pre- and post-cruise pressure calibrations, Figures 2a and2b, were 
compared.  The warm/shallow and cold/deep calibration curvesboth shifted by 
about 8 decibars from pre- to post-cruise.  The slopesof the 2 sets of pressure 
calibration curves differed by a maximum of1 decibar over 6000 decibars.  
Thermometric pressures were notmeasured during either leg.

CTD #2 surface raw pressure data were compared over the course ofboth legs to 
determine when the 8-decibar shift might have occurred.CTD #2 was used on Leg 1 
for each LADCP cast: every other station from81 through 117.  There was no 
apparent shift in the surface rawpressures during this time:  all values, down 
or up cast, were within1 decibar of each other at equatorial surface 
temperatures.  These rawpressures were approximately halfway between the pre- 
and post-cruiselaboratory calibration values at similar temperatures.

The Leg 2 CTD #2 casts, stations 137-150 and 183-188, were alsochecked.  Down 
and up cast raw pressures were consistent and anaverage 2 decibars lower than 
the Leg 1 values, closer to the pre-cruise calibration than Leg 1.  There was no 
shift in raw pressurevalues between stations 150 and 183.

The pre-cruise calibration was left in place for the CTD #2pressure data on both 
legs because of negligible slope differencesbetween pre- and post-cruise 
calibrations.  Any residual offset wascompensated for automatically at each 
station: as the CTD enters thewater, the corrected pressure is adjusted to 0 
decibars.

4.1.1.3.  CTD #10

CTD #10 could not be calibrated post-cruise: the instrumentflooded during the 
first/aborted cast at station 182 and was subjectedto major repairs and 
adjustments after the cruise.  Any calibrationdata collected after this repair 
would not apply to the TUNES cruises.

Thermometric pressures were not measured during Leg 2.  The pre-cruise pressure 
calibration, Figure 3, remained in effect for the CTD#10 data on Leg 2.

4.1.2.    CTD Temperature Corrections

4.1.2.1.  CTD #1

CTD #1 had two temperature sensors: PRT-1 was calibrated pre- andpost-cruise; 
PRT-2 was only calibrated pre-cruise and was used tocheck for PRT-1 drift during 
the cruise.  A comparison of the pre- andpost-cruise laboratory CTD #1 PRT-1 
temperature transducercalibrations, Figures 4a and 4b, showed two curves with 
nearlyidentical slopes and a +.0025 deg.C temperature shift in the range of0 to 
32 deg.C.  An average of the two laboratory calibrations, Figure4c, was applied 
to the CTD #1 temperature data.

Thermometric temperature data from Leg 2, stations 189 through220, were compared 
to the calibrated CTD #1 temperature data.  Theaverage difference between 
thermometric data and final calibrated CTDdata was 0+/-.0005 deg.C, in good 
agreement with the averagelaboratory calibration used.
4.1.2.2.  CTD #2

CTD #2 also had two temperature sensors, each calibrated pre- andpost-cruise, 
Figures 5a/b (PRT-1) and 5c/d (PRT-2).  PRT-1, theprimary sensor, shifted an 
average +.044 deg.C between calibrations;PRT-2, the secondary sensor, shifted an 
average -.011 deg.C.  Theslopes also shifted by about .004 deg.C each over the 
30 deg.Ctemperature range of the calibrations.  The PRT-1 minus PRT-2difference 
changed by +.055 deg.C between calibrations at both coldand warm temperatures.


CTD #2 Laboratory Temperature Calibrations

      CTD #2 | Lab.Calib. | Std.-CTD|T (deg.C) |  Change   | Avg. Change
      Sensor |   Temp.    | Pre-crs | Post-crs | in Corrxn |  in CTD T  
      -------|------------|---------|----------|-----------|------------
      PRT-1  | 0 degC     | -1.486  |  -1.528  |   -.042   |            
             | 30 degC    | -1.496  |  -1.542  |   -.046   |    +.044   
      -------|------------|---------|----------|-----------|------------
      PRT-2  | 0 degC     | -1.497  |  -1.484  |   +.013   |            
             | 30 degC    | -1.495  |  -1.486  |   +.009   |    -.011   


PRT-1 drifting was first noticed during Leg 2, station 149, as apossible 
conductivity problem; PRT-1 temperature offsets as large as+.7 deg. C were noted 
during station 150.  After CTD #10 flooded andCTD #1 was under repair for 
continuing conductivity noise problems,CTD #2 was used again for stations 183-
188.  The secondary sensor wasused for CTD temperature data during these casts, 
and DSRT thermometerdata were collected to monitor any PRT-2 sensor drifting 
problems.

The two PRTs were monitored shipboard to check for drifting orother problems.  
At first glance, PRT-1 appeared to be stablethroughout the Leg 1 casts for which 
it was used; but PRT-1 minusPRT-2 differences had already shifted by 
approximately +.007 deg.Ccompared to the pre-cruise calibration.  Either sensor 
could haveshifted in its pre- to post-cruise direction to cause this 
change,which was 3 times the WOCE standard.

The two PRTs were compared by lagging the faster PRT-1 rawtemperature data by 
.15 seconds to match the PRT-2 raw data.  PRT-1minus PRT-2 differences were 
tabulated for Leg 1 and Leg 2 CTD #2casts to determine when temperature shifts 
occurred.  The PRT-1 datawas too unstable to use for the comparison beginning 
with station 148.The results of the comparison are as follows:

The above comparison is only helpful if it can be determined wheneach PRT 
shifted.  Two thermometric temperature points per cast weremeasured on stations 
183-188 as a calibration check for PRT-2.  TheDSRT vs. PRT-2 comparisons 
indicate agreement with the post-cruisePRT-2 calibration.  The average residual 
DSRT-CTD difference afterapplying the post-cruise calibration is +.0034 deg.C, 
the closestdifference possible using either of the lab calibrations, or even 
acombination of the two.

PRT-2 had clearly shifted to the post-cruise temperaturecalibration by stations 
183-188, and corrections were appliedaccordingly.  The rest of the temperature 
corrections were determinedfrom this information, combined with clues provided 
by an apparentlystable CTD #2 conductivity sensor.

In an attempt to clarify when each sensor shifted, the CTD #2data from Leg 1 and 
Leg 2 were block-averaged two ways: using PRT-1 orPRT-2 temperature data to 
calculate CTD salinity.  PRT-2-basedsalinity corrections for stations 150/183 
were comparable using thepost-cruise temperature calibration.  Using this same 
PRT-2calibration for stations 137-150 also showed a smooth salinitypicture, 
indicating that PRT-2 had shifted to its post-cruisecalibration by the start of 
Leg 2.

PRT-2 was used for the primary temperature data for stations148-150 based on 
major shifts in conductivity slopes from 147 to 148when PRT-1 temperature data 
were used, and because of PRT-1temperature shifts observed during stations 149-
150.  PRT-2 was notlocated as near to the conductivity sensor as PRT-1, so it 
generatednoisier CTD salinity data: it was measuring slightly different waterand 
could not be matched properly to the conductivity sensor response.Because of 
this, PRT-1 was used for all CTD #2 data prior to station148, before it began to 
malfunction.

The PRT-1 minus PRT-2 difference was used to determine the Leg 2PRT-1 
calibration for stations 137-147.  The pre-cruise calibrationwas used, with an 
offset, because the strange behavior of PRT-1beginning at station 148 could have 
affected the post-cruisecalibration slope and it would not apply to earlier 
casts.  Theaverage pre- to post-cruise calibration drift for PRT-2 was -
.011deg.C; the average PRT-1 minus PRT-2 change from pre-cruise tostations 137-
147, for cold or warm temperatures, was .0285 deg.C.  AsPRT-2 drifted lower, 
increasing the difference by .011, PRT-1 had todrift higher; so the PRT-1 pre-
cruise calibration curve was decreasedby -.0175 deg.C for stations 137-147.  A 
smooth salinity correctionfor the PRT-1/PRT-2 transition at stations 147-148 
verified thisdecision.

The Leg 1 PRT-1 minus PRT-2 differences shifted an average +.0075deg.C, cold or 
warm, compared to the pre-cruise calibrations.  Nothermometer data was collected 
during this leg to verify which PRT(s)had changed since the pre-cruise 
calibration.  Salinity differences from the last CTD #2 casts of Leg 1 and the 
first CTD #2 casts fromLeg 2 were compared.  When the Leg 1 PRT-1 temperatures 
were correctedwith the pre-cruise calibration and a -.0075 deg.C offset, the 
Leg1/Leg 2 salinity differences were within .003 psu, a normal shiftafter any 
CTD has been on-deck and sitting idle for several weeks.This PRT-1 correction, 
which assumes that PRT-2 did its entire shiftbetween Legs 1 and 2, was used for 
all CTD #2 casts on Leg 1.

After Leg 2 conductivity/salinity corrections were calculated,there was up to a 
+.005 psu residual surface salinity offset forstations 143-147, indicative of an 
earlier PRT-1 problem thanpreviously thought.  Two options were considered: use 
PRT-2 fortemperature or use PRT-1 with an additional first-order T 
correction.Because of the noisy salt signal that results from using PRT-2, it 
wasdecided to use the added first-order T correction to PRT-1 forstations 143-
147.  This gave the best deep T/S data while pulling inthe surface differences.
A summary of the origin and correction of CTD #2 temperature  data  islisted

4.1.2.3.  CTD #10

CTD #10 had two temperature sensors, both calibrated pre-cruiseonly.  CTD #10 
could not be calibrated post-cruise: the instrumentflooded during the 
first/aborted cast at station 182 and was subjectedto major repairs and 
adjustments after the cruise.  Any calibrationdata collected after this repair 
would not apply to the TUNES cruises.

No thermometric temperatures were measured for this CTD.  ThePRT-1 minus PRT-2 
difference shifted -.002 deg.C from the pre-cruiselaboratory calibration, 
Figures 6a/b, to the first TUNES CTD #10 cast.The PRT difference changed by a 
maximum -.002 deg.C from the first tothe last CTD #10 cast (stations 151-181).  
The conductivity correctionshifted by more than .04 psu during this same time, a 
change 20 timesgreater than the PRT differences could account for.  The pre-
cruisecalibration notes for CTD #10 indicated that PRT-2 was unstable, so itwas 
assumed that any shift in the PRT difference was due to changes inPRT-2.  The 
pre-cruise PRT-1 temperature calibration, Figure 6a,remained in effect for the 
CTD #10 data on Leg 2.

4.1.3.  CTD Conductivity Corrections

In order to calibrate CTD conductivity, check-sampleconductivities were 
calculated from the bottle salinities using CTDpressures and temperatures.  For 
each cast, the differences betweensample and CTD conductivities at all pressures 
were fit to CTDconductivity using a linear least-squares fit.  Values greater 
than 2standard deviations from the fits were rejected.  The 
resultingconductivity correction slopes were plotted as a function of 
stationnumber.  The conductivity slopes were grouped by stations, based on
common PRT and conductivity sensor combinations, and then fit as afunction of 
station number to generate smoothed slopes for each group.These smoothed slopes 
were either averages of the slopes in thestation group (0-order) or changing by 
a fixed amount from station tostation (1st-order).

Conductivity differences were then calculated for each cast afterapplying the 
preliminary conductivity slope corrections.  Residualconductivity offsets were 
computed for each cast and fit to stationnumber.  Smoothed offsets were 
determined by groups as above, based oncommon PRT and conductivity sensor 
combinations.  The resultingsmoothed offsets were then applied to the data.  
Then conductivityslope as a function of conductivity was re-checked: no changes 
werewarranted.

Some offsets were manually adjusted to account for discontinuousshifts in the 
conductivity transducer response, or to insure aconsistent deep T-S relationship 
from station to station.

4.1.3.1.  Leg 1

CTD #1 and #2 were both used on Leg 1 without any apparentconductivity problems.  
They were mounted on different rosettes andused for opposite casts during the 
equatorial stations to allow foradequate sampling time on the larger rosette 
without loss of shiptime.  CTD #1 was on the 36-place rosette, while CTD #2 was 
on a12-place rosette with the LADCP.  Plots of the final Leg 1conductivity 
slopes and offsets can be found in Figures 7a and 8a.

4.1.3.2.  Leg 2

During Leg 2, the CTD #1 conductivity sensor had downcast noiseproblems of .005 
psu or larger beginning with station 133.  Theconductivity sensor was switched 
out for a spare before station 134,but the problem continued and actually 
tripled in size by station 136.Other CTDs were used until CTD #2's PRT problems 
and CTD #10'sflooding problems required trying CTD #1 again, with its 
originalconductivity sensor, at station 182; the noise problem continued.  CTD#2 
was again used for several stations until it locked up.

CTD #1 was brought back on line at station 189 as a mixture ofparts from CTDs #1 
and #2.  Following numerous repair attempts andpart switching, the culprit was 
discovered to be a coating on thePRT/Conductivity sensor guard that was flaking 
off and flapping infront of the sensor on the downcasts.  The coating was 
removed and there were no more noise problems beginning with station 197.  
Becauseof severe conductivity noise problems on their downcasts, the upcastswere 
used for stations 133-136, 182, and 189-196. Plots of the finalLeg 2 
conductivity slopes and offsets can be found in Figures 7b and8b.

4.2.  CTD Dissolved Oxygen Data

4.2.1.  CTD Oxygen Corrections

Dissolved oxygen data were acquired using Sensormedics dissolvedoxygen sensors.  
During TUNES Legs 1 and 2, two oxygen sensors wereused.  Sensor A was used with 
all CTDs for every station except188-192, where it was temporarily replaced with 
sensor B because ofoxygen signal problems.

CTD oxygen data are corrected after pressure, temperature andconductivity 
corrections have been determined.  CTD raw oxygencurrents were extracted from 
the pressure-series data at isopycnalscorresponding to the up-cast check 
samples.  Most pressure-series datawere from the down casts, where oxygen data 
are usually smoother thanup-cast data because of the more constant lowering 
rate, avoiding theflow-dependence problems occurring at up-cast bottle stops.  
However,the TUNES CTD oxygen data were affected with flow-dependence 
problems,down or up cast, each time a cast was stopped for several minutesaround 
20 decibars to activate/de-activate the heave compensator.

The CTD oxygen correction coefficients were determined byapplying a modified 
Levenberg-Marquardt nonlinear least squaresfitting procedure to residual 
differences between CTD and bottleoxygen values.  Bottle oxygen values were 
weighted as required tooptimize the fitting of CTD oxygen to discrete bottle 
samples.  Some bottle levels were omitted from a fit because of large 
pressuredifferences between down- and up-cast CTD data at isopycnals.  Deepdata 
points were often weighted more heavily than shallower data dueto the higher 
density of shallow sampling on a typical 36-bottlesampling scheme.

The TUNES surface oxygen data fitting was adversely affected bythe long heave 
compensator stop which, combined with the typicalgoing-in-water bubbles/noise, 
made it difficult to fit CTD oxygens tothe bottle data in the surface mixed 
layer of many casts.

4.2.2.  Bottle vs. CTD Oxygen Statistical Summary

The CTD oxygens are generated by fitting up cast oxygen bottledata to down cast 
CTD raw oxygen (microamps) measurements along isopy-cnals.  Residual oxygen 
differences are not generated from these com-parisons, so no comparison 
statistics are shown in this report.


4.3.  Additional Processing

A software filter was used on 36 Leg1 casts and 40 Leg2 casts toremove 
conductivity or temperature spiking problems in about 0.1% ofthe time-series 
data frames.  Pressure did not require filtering.  Afourth of the T/C spiking 
problems occurred in station 182, andanother fourth were concentrated in the 
CTD-2/PRT-2 casts, where thedistance between the secondary PRT and the 
conductivity sensorresulted in poor signal matchup in high-gradient areas.

Oxygen spikes were filtered out of 2 Leg1 casts and 91 Leg2casts; software 
improvements prior to the Leg2 oxygen processingenabled this large difference in 
oxygen filtering.  The filteredoxygen levels affected approximately 2.5% of the 
time-series dataframes.  76% of the filtered oxygen data were shallower than 100 
dbarsand could be directly related to the stop at the heave 
compensatoractivation/de-activation, or bubbles trapped during the going-in-
watertransition.

The remaining density inversions in high-gradient regions cannotbe accounted for 
by a mis-match of pressure, temperature andconductivity sensor response.  
Detailed examination of the raw datashows significant mixing occurring in these 
areas because of shiproll.  The ship-roll filter resulted in a reduction in the 
amount andsize of density inversions.

After filtering, the down cast (or up cast - see table below)portion of each 
time-series was pressure-sequenced into 2-decibarpressure intervals.  A ship-
roll filter was applied to each castduring pressure sequencing to disallow 
pressure reversals.  The heavecompensator installed on the R/V Washington 
decreased the magnitude ofshiproll effects to a level comparable to 
Melville/Knorr CTD casts.


5.  General Comments/Problems

There is one pressure-sequenced CTD data set, to near the oceanfloor, for each 
of 221 casts at 220 station locations.  There was anextra CTD cast at station 
98, the equator station for Leg 1, tocollect LADCP data.  There were four 
additional equipment test casts,plus four casts aborted because of various CTD 
problems; these wereneither processed nor reported.  Another CTD cast was done 
immediatelyafter any aborted cast at the same location.



The data reported is from down casts, excepting the stationslisted below:

The 0-2 decibar level(s) of some casts were extrapolated using aquadratic fit 
through the next three deeper levels.  Recorded surfacevalues were rejected only 
when it appeared that the drift was causedby sensors adjusting to the in-water 
transition; if there were anyquestion that the that the surface values might be 
real, the originaldata was reported.  Extrapolated surface levels are identified 
by acount of "1" in the "Number of Raw Frames in Average" reported witheach data 
record on the tapes.

Several shipboard time-series data sets had areas of missing ornoisy data.  
These casts were recovered by re-digitizing the rawsignal from analog tape.  The 
top 8 db of one Leg1 cast and 4 non-surface data levels in 2 Leg2 casts were 
interpolated.  The pressuresfor these interpolated data frames as well as other 
cast-by-castshipboard or processing comments are listed in the "CTD 
ProcessingComments" in Appendix D.  All interpolated data levels have a count 
of"1" in the "Number of Raw Frames in Average" column in the data files.

In addition, missing data values, such as CTD oxygens in castswhere the sensor 
failed, are represented as "-9" in the data files.There were two casts (stations 
183-184) where the oxygen signal failedonly during the top 200 decibars; these 
are not reported as "-9", butthe affected pressures are listed in Appendix D.

The CTD oxygen sensor often requires several seconds in the waterbefore being 
wet enough to respond properly; this is manifested as lowor high CTD oxygen 
values at the start of some casts.  Flow-dependenceproblems occur when the 
lowering rate varies, or when the CTD isstopped, as at the cast bottom, bottle 
trips or the heave-compensatoractivation, where depletion of oxygen at the 
sensor causes loweroxygen readings.  Station 133 oxygen data demonstrate a 
typical oxygendepletion effect at each bottle stop.  Delays and yoyos during 
thecasts are documented in Appendix D.


C.2  Gerard Bottles

Gerard pressures and temperatures were calculated from Deep-Sea Reversing 
Thermometer (DSRT) readings. Each DSRT rack normally held 2 protected 
(temperature) thermometers and 1 unprotected (pressure) thermometer. 
Thermometers were read by two people, each attempting to read a precision equal 
to one tenth of the thermometer etching interval. Thus, a thermometer etched at 
0.05 degree intervals would be read to the nearest 0.005 degrees. Each 
temperature value is therefore calculated from the average of four readings 
provided both protected thermometers function normally.

The temperatures are based on the International Temperature Scale of 1990.

C.3  Salinity

Salinity samples were drawn into 200ml Kimax high-alumina borisilicate bottles 
with custom-made plastic insert thimbles and Nalgene screw caps. This assembly 
provides very low container dissolution and sample evaporation. Salinity bottles 
were rinsed three times before filling. Salinity was determined after sample 
equilibration to laboratory temperature, usually within about 8-36 hours of 
collection. Salinity has been calculated according to the equations of the 
Practical Salinity Scale of 1978 (UNESCO, 1981). This calculation uses the 
conductivity ratio determined from bottle samples analyzed (minimum of two 
recorded analyses per sample bottle after flushing) with a Guildline Autosal 
Model 8400A salinometer. The salinometer was standardized against Wormley P-114 
standard seawater, with at least one fresh vial opened per cast.

Accuracy estimates of bottle salinities run at sea are usually better than 0.002 
psu relative to the specified batch of standard. Although laboratory precision 
of the Autosal can be as small as 0.0002 psu when running replicate samples 
under ideal conditions, at sea the expected precision is about 0.001 psu under 
normal conditions, with a stable lab temperature.

C.4  Oxygen

Samples were collected for dissolved oxygen analyses soon after the rosette 
sampler was brought on board and after CFC and Helium were drawn. Nominal 100 or 
125 ml volume iodine flasks were rinsed carefully with minimal agitation, then 
filled via a drawing tube, and allowed to overflow for at least 2 flask volumes. 
Reagents were added to fix the oxygen before stoppering. The flasks were shaken 
twice; immediately after drawing, and then again after 20 minutes, to assure 
thorough dispersion of the Mn(OH)2 precipitate. The samples were analyzed within 
4-36 hours.

Dissolved oxygen samples were titrated in the volume-calibrated iodine flasks 
with a 1 ml microburet, using the whole-bottle Winkler titration following the 
technique of Carpenter (1965) with modifications by Culberson et. al. (1991). 
Standardizations were performed with 0.01N potassium iodate solutions prepared 
from preweighed potassium iodate crystals. Standards were run at the beginning 
of each session of analyses, which typically included from 1 to 3 stations. 
Several standards were made up and compared to assure that the results were 
reproducible, and to preclude basing the entire cruise on one standard, with the 
possibility of a weighing error. A correction was made for the amount of oxygen 
added with the reagents. Combined reagent/seawater blanks were determined to 
account for oxidizing or reducing materials in the reagents, and for a nominal 
level of natural iodate (Brewer and Wong, 1974) or other oxidizers/reducers in 
the seawater. These latter corrections are contrary to the recommendations of 
Culberson et al. (1991), which call for the determination of reagent blanks in 
distilled water. ODF standard procedures have since been aligned with those 
recommended by Culberson.

Oxygens were converted from milliliters per liter to micromoles per kilogram 
using the in-situ temperature. Ideally, for whole-bottle titrations, the 
conversion temperature should be the temperature of the water issuing from the 
Niskin bottle spigot. The temperature of the samples was measured at the time 
the sample was drawn from the bottle, but were not used in the conversion from 
milliliters per liter to micromoles per kilogram because the software was not 
available. Aberrant temperatures provided an additional flag indicating that a 
bottle may not have tripped properly. Measured sample temperatures from mid-deep 
water samples were about 4-7°C warmer than in-situ temperature. Converted oxygen 
values, if this conversion with the measured sample temperature were made, would 
be about 0.08% higher for a 6°C warming (or about 0.2µm/kg for a 250µm/kg 
sample.)

C.5  Nutrients

Nutrients (phosphate, silicate, nitrate and nitrite) analyses, reported in 
micromoles/kilogram, were performed on a Technicon AutoAnalyzer(r). The 
procedures used are described in Hager et al. (1972) and Atlas et al. (1971). 
Standardizations were performed with solutions prepared aboard ship from 
preweighed standards; these solutions were used as working standards before and 
after each cast (approximately 36 samples) to correct for instrumental drift 
during analyses. Sets of 4-6 different concentrations of shipboard standards 
were analyzed periodically to determine the linearity of colorimeter response 
and the resulting correction factors. Phosphate was analyzed using hydrazine 
reduction of phosphomolybdic acid as described by Bernhardt & Wilhelms (1967). 
Silicate was analyzed using stannous chloride reduction of silicomolybdic acid. 
Nitrite was analyzed using diazotization and coupling to form dye; nitrate was 
reduced by copperized cadmium and then analyzed as nitrite. These three analyses 
use the methods of Armstrong et al. (1967).

Sampling for nutrients followed that for the tracer gases, CFC's, He, Tritium, 
and dissolved oxygen. Samples were drawn into ~45 cc high density polyethylene, 
narrow mouth, screw-capped bottles which were rinsed twice before filling. The 
samples may have been refrigerated at 2 to 6°C for a maximum of 15 hours.

Nutrients were converted from micromoles per liter to micromoles per kilogram by 
dividing by sample density calculated at an assumed laboratory temperature of 
25°C.

C.6  Chlorofluorocarbons 
     (Kevin F. Sullivan and Kevin A. Maillet)

Concentrations of the dissolved atmospheric cholorfluorocarbons (CFCs) F-11 and 
F-12 were measured by shipboard electron-capture gas chromatography according to 
the methods described by Bullister and Weiss (1988). The measurements were 
carried out by the group at the University of Miami under the direction of Dr. 
Rana A. Fine. A total of 1627 water analyses were carried out, 9 of which were 
duplicate analyses as tabulated in Table B.8.1. The mean value of duplicate 
analyses are reported in the data file and are assigned a quality byte of 6.

Several times during the cruise, problems with the analytical system required 
extensive downtime. If samples were drawn, but not analyzed, and the downtime 
exceeded 6 to 8 hours, some or all of these samples were discarded and fresh 
samples were drawn on the current station. This situation occurred after 
stations 16 and 24. In accordance with WHP protocol, the value for these 
analyses has been reported as -9.000 and they have been assigned a quality byte 
of 5. After station 46, the analysis of the samples was delayed 3 hours while a 
problem was eliminated.

On a number of occasions, the CFC analysis appeared routine yet the values 
obtained were clearly inappropriate based on the depth at which the Niskin was 
tripped. Upon further inspection it was noticed that there appeared to be 
problems with other measured quantities from these bottles as well. While the 
groups reporting hydrography and nutrients have chosen to eliminate the data in 
these situations, this group will report the data as measured and have assigned 
a data qulity flag of 4 to the quality byte for that measurement. It is 
considered that this is more in keeping with the WHP standard protocol that all 
data should be reported. In our view, the quality byte assigned to the bottle 
itself should be changed to 4 and the measured data retained. Situations where 
this occurred were:

S(tation) 6, N(iskin) 5; S 7, N 1; S 9, N 5 & 6; S 10, N 5 & 6; S 31, N 6.

The following analyses are suspect in relation to the surrounding values and 
have been flagged as bad data (quality byte 4):

S 10, N 33, F11; S 14, N 33, F11; S 61, N 6 & 7, F12; S 98, N 23, F12; S 122, N 18, F11.

A combination bottle and handling blank was used to correct for contamination 
from the Niskin bottles and from the collection and storage of the samples. This 
blank was estimated by analyzing samples from Niskins after they were tripped in 
what is believed to be CFC-free water. Since it is common for the blank arising 
from the Niskin bottles to be higher at the beginning of a cruise and to become 
progressively lower throughout the cruise, blanks were estimated over ranges of 
stations and applied to water analyses occurring during these ranges. In cases 
where the bottle/handling blank is greater than the measured concentration, a 
negative concentration is reported in the data file. A list of all Niskins and 
their bottle/handling blanks over the entire cruise is included in Table B.8.2.

Measurements of the atmospheric concentration of F-11 and F-12 were carried out 
regularly during the cruise. Air samples were pumped through a Decabond tubing 
air line run along the railing of the ship and up the mast at the bow. Air 
measurements were usually carried out while on station when the bow of the ship 
was heading into the wind to avoid contamination from the stack. Usually, three 
to six air measurements were carried out in sequence. The mean values of 
replicate air analyses are tabulated in Table B.8.3

C.7  BOTTLE DATA COMPARISONS AND COMMENTS

The oxygen and nutrient data were compared by ODF with those from the adjacent 
station. Dr. Mizuki Tsuchiya and Dr. Lynne Talley did comparisons with 
historical data sets.

Cruise 31WTTUNES/1 had several start-up problems, due to moderately rough 
weather, pylon problems, and the close spacing of the initial run of stations. 
Until the pylon problems were sorted out, there were substantial portions of the 
water column without verifiable water samples. Most closure problems were solved 
by the time the vessel began the WOCE run along 135°W.

Post cruise assessment revealed that the practice of renumbering replacement 
Niskin bottles (to keep numbers in sequence), was at least occasionally followed 
on this cruise leg. This goes against ODF and WOCE policy. it may be possible to 
reconstruct bottle numbering history for this cruise leg, but at significant 
cost (the deck log is occasionally vague on this point), and so no changes have 
yet been made to the bottle numbers as reported from the shipboard data file.

E.  BOTTLE DATA COMMENTS

Remarks for deleted or missing samples from TUNES/WOCE Pacific 91, P17C. 
Investigation of data may include comparison of bottle salinity and oxygen with 
CTD data, review of data plots of station profile and adjoining stations, 
rereading of charts (ie. nutrients). Comments from the Sample Logs and ODF's 
results of investigation are included in this report.


Station 001

122 @ 42db   Sample log: Spring needs tightening. All water 
             samples look good at 42m.

131 @ 293db  Delta-S .010 low at 343db. Calc ok. No notes. 
             All water samples have same value as NB30 at level above. 
             CTDO traces show smoother gradient this area Assume closed 
             at NB30 level (292db). Changed trip file made 31 same trip 
             info as 30. Used 292.7 vs. 343.2 CTD trip data for NB31.

133 @ 443db  Delta-S .050 low at 442db. Calc ok. No notes. 
             Other water samples ok. Same value as NB32 at level above. 
             Assume dupe draw. Footnote salinity uncertain, ODF 
             recommends deletion.
134 @ 492db  Salinity same value as 33 at level above. 
             Assume dupe draw. Footnote salinity uncertain, ODF 
             recommends deletion.
135 @ 519db  Sample log: Leaking from bottom end cap. Delta-
             S .003 high at 519db. Other water samples also look ok.
136 @ 519db  Delta-S .026 low at 550db. Calc ok. No notes. 
             All water samples have same values as NB35 at level above. 
             CTDO salinity and oxygen traces show definite change between 
             NB35 level at 519db and NB36 level. Assume NB36 closed at 
             519db level. Changed trip file made 36 same trip info as 35. 
             Used 518.9 vs. 550.3 CTD trip data for NB36.

STATION 002

113          Bottle was closed but not intended as a sample. NBs 14 
             thru 17 were open as intended and ramp shaft in correct 
             position. Water samples same as NB36 so assume NB 13 closed 
             at first trip. This level is not reported.
129 @ 303db  Sample Log: "Air vent open" Delta-S -0.007 at 
             303db, in line with all other offsets on this station. O2 
             agrees with CTDO.
130 @ 353db  Sample Log: "Air vent open" Delta-S -0.006 at 
             353db, in line with all other offsets on this station. O2 
             agrees with CTDO.

STATION 003

136 @1473db  Sample log: Spigot on deck, bottom end cap 
             lanyard broken. Didn't see what happened. No water samples.

STATION 004

111 @ 77db   Sample log: Stepped on lanyard - let out some 
             water. O2 appears to follow CTDO trace well. Other water 
             samples also ok.
114 @ 149db  Sample log: Leaking out of bottom. Delta-S .03 
             low at 148db. Calc ok. High gradient, down differs from up, 
             CTD temp also bumpy this area. Other water samples look 
             reasonable.
117 @ 298db  Sample log: Leaker. Not specific. Delta-S .000 
             at 297db. Other water samples also ok.
135 @2397db  Sample log: Water valve cracked. Delta-S .000 
             at 2396db. Other samples also okay.

STATION 005

106 @ 143db  Sample log: Closed top late in sampling. Spigot 
             is tight. Spigot difficult to close. Delta-S .032 high at 
             143db. Calc ok. High gradient. Other water samples look ok 
             near CTDO inversion.
109 @ 210db  Sample log: Air vent partially open. Delta-S 
             .02 low at 210 db. Calc ok. Other water also indicate 
             possible leaker but in area of change.
110 @ 261db  Sample log: Air vent partially open. Delta-S 
             .013 low at 261db. Calc ok. Other water samples look ok.
117 @ 605db  Sample log: Air leak. Delta-S .000 at 604db. 
             Other water samples look ok.
118 @ 655db  Delta-S .074 high at 655db. Calc ok. No notes. 
             Other water samples ok. Same value as NB20 2 level deeper. 
             Smooth CTD S trace. Possibly bad draw or bad run. Footnote 
             salinity uncertain, ODF recommends deletion.
121 @ 909db  Bottle oxy appears .1 low at 909db. Calc ok. 
             CTDO trace smooth, although unclear from CTDO whether 121 is 
             low or 119 & 120 are a little high. Footnote o2 uncertain.
128 @2019db  Bottle oxy appears .1 high at 2019db. Calc ok. 
             CTDO trace smooth, footnote o2 uncertain. Delta-S .002 low.
129 @2219db  Sample log: Disc off while sampling. Samples 
             look reasonable. Okay as is.
134 @3251db  Final Delta-S .003 high at 3251db. Calc ok. 
             Smooth CTD gradient. Tsuchiya: "Is this o2 max real? It 
             looks either o2 at 134 is too high or o2 at 135 and 136 is 
             too low." Calc okay, CTDO indicates 135 & 136 too low.
135 @3356db  Bottle oxy appears .1 low. Calc ok. Footnote o2 
             uncertain. CTDO trace has slight jog this way but not .1. 
             Other water samples & CTD traces have smooth gradient. Final 
             Delta-S .005 high at 3356db. Calc ok. Smooth CTD gradient.
136 @3446db  Bottle oxy appears .1 low. Calc ok. Footnote o2 
             uncertain. CTDO trace has slight jog this way but not .1. 
             Other water samples & CTD traces have smooth gradient. Final 
             Delta-S .005 high at 3446db. Found entry error, new hydro 
             salt gives final Delta-S .0027 high.

STATION 006

105 @ 90db   Not sure what happened here. No notes on Sample 
             Log. Samples indicate bottle tripped at ~1200-1450db. Delete

112 @ 297db  Sample log: Bottom cap knocked open. Tsuchiya: 
             "O2 too high?" Delta-S .002 high at 297db. Discrete O2 .7 
             high, calc ok. Nutrients look ok. Footnote oxygen bad. 
             Oxygen seems to be affected by note from sample log, may 
             also have affected other gas samples.
113          Sample log: Moved freon to bottle 22. No water samples.

             at 2223db is .004.
129 @2435db  Changed trip file, scheduled trip 2652. Delta-S 
             at 2435db is .0048. Salinity a little noisy for entire 
             trace. Footnote salinity uncertain.
130 @2435db  Delta-S .008 low at 2637.9db. Calc ok. All 
             water samples same as 129 at 2436.4db. Assume trip problem, 
             nothing tripped at 2637.9db and both NBs 29 & 30 tripped at 
             2436.4db. Used 2436.4 vs. 2636.5 CTD trip data for NB30. 
             Changed trip file, scheduled trip 2852. Silicate: Couldn't 
             read peak. Peak very jagged between .990 and 1.000.
131 @2840db  Changed trip file, scheduled trip 3046.
132 @3034db  Delta-S at 3034db is .004. Changed trip file,

134 @3451db  Changed trip file, scheduled trip 3673. Delta-S 
             at 3451db is .003. Console Ops Log: "13 still open. No 
             trigger at 34. Delta-Ss on 34 thru 14 give good agreement if 
             all samples moved up one level from intended level.

STATION 007

1sil         Tsuchiya: "Is the increase in sil level in deep layer 
             (>~2000db) from Station 6 to 7 is real." Samples 125- 
             136,Calc appears to be okay, no problems noted.
101 @ 2db    Delta-S 1.9 high at 1db. Calc ok. All water 
             samples indicate bottle closed deep. NO2 unreadable peak, 
             footnote no2 lost. Footnote bottle leaking. Delete salinity, 
             o2, sil, no3, po4, 34.6273 118.6 166.28 38.16 2.65 , 
             respectively.
105 @ 104db  Nutrient: no2 unreadable peak.
108 @ 180db  Sample log: Top was out of frame. Trip rod out 
             of top plate, replaced trip rod later, found broken rod had 
             been used and was too short. Samples look ok.
117 @ 812db  Sample log: Slight air leak. Oxygen looks good. 
             Leave as is.
118 @1006db  Delta-S .02 high at 897db. Calc ok. All water 
             samples indicate bottle closed closer to NB19 at 1005db. 
             Talley: "Footnote salinity as questionable." Salinity sheet 
             notes indicate analyst had to bring in the cast. Delta-S -
             .0112 at 1006 db. Suspect that he was distracted and this 
             salinity is incorrect footnote salinity bad, ODF recommends 
             deletion. Change trip file, scheduled 897.
120 @1006db  Delta-S .02 low at 1110db. Calc ok. All water 
             samples indicate bottle closed at NB19 at 1005db. Change

131 @3034db  Delta-S at 3034db is -.005, calc ok. Footnote 
             salinity uncertain. O2 .02 low compared to CTDO, calc ok. 
             Footnote o2 uncertain. Nutrients have more normal gradient.
134 @3555db  Delta-S .007 low at 3821db. Calc ok. Same as 
             133 salt at level above. NO3 & PO4 also same as 133 but Sil 
             & O2 show some gradient. Sil has poor peak that could be 
             interpreted as same as 133. O2 titrated by LTL who had 
             several overtitrations early in the cruise. Suspect tripping 
             problem and NB34 closed at NB33 level. Used 3554db CTD trip 
             data for NB34. Changed trip file made 34 same trip info as 
             33.
136 @4227db  Sample log: Air leak - vent closed - possible 
             bottle crack? Delta-S .002 low at 4226db. Nutrients for 35 & 
             36 lower than other deep bottles but subsequent deep 
             stations show same feature NB 36 ok on subsequent stations. 
             Oxygen okay.

             stations) of NO3 at the NO3 max and below (>~100db) is 
             real?" Calc and peaks okay, no analytical problems noted. 
             Samples 119-136.

C.4.  LARGE VOLUME SAMPLING: P17C  31WTTUNES_1 (TUNES 1)
      (Robert M. Key, PI)
      17 July 1995

                                                              DATA SUBMITTED BY:
                                             Scripps Institution of Oceanography
                                                     Oceanographic Data Facility


DESCRIPTION OF MEASUREMENT TECHNIQUES AND CALIBRATIONS

Large Volume Sampling (LVS) was performed on this expedition.  These
commonly referred to as Gerard casts were carried out with ~270 liter
stainless steel Gerard barrels on which were mounted 2-liter Niskin bottles
(Piggyback bottles) with reversing thermometers.

There were 17 large volume stations, with at least one deep cast (2500db to
the bottom), and either or both an intermediate (1000db to 2500db) and/or a
shallow cast (surface to 1000db). There were 21 casts total, 4 of which
were redeployments to complete the complement of 9 levels. The cast was
relowered if the complement of 9 levels was not achieved due to pretrips or
failure of one Gerard barrel releasing it's messenger thereby tripping the
rest of the string of barrels.  The Gerard barrel platform, as set up in
port prior to the cruise, did not allow enough clearance for barrel during
deployment & recovery.  The Chief Engineer cut the platform loose and
rewelded it to the deck about one foot forward.  The spring-loaded
trapping-pin was no longer usable so a chain was shackled to one forward
corner of the platform, passed aft of the wire then hooked to the other
forward corner to hold the trawl wire in the platform "V" while the barrels
were being attached and detached.  Limited fantail space and the low trawl
wire lead required that the crane work over the wire to move barrels from
racks to near the centerline just forward of the platform, then the barrel
was unhooked and the crane moved to the other side of the wire and rehooked
to move the barrel to the attachment position. This procedure was reversed
for recovery.  Working Gerards off the stern went well in good weather but,
as expected, pitching in moderate seas (15-20 knots wind) caused tripping
problems. Slowing down the lowering rate to less than 50 meters/minute
seemed to help.

Samples for salinity, silicate and 14C were obtained from the Gerard
barrels; samples for salinity were drawn from the piggyback bottles.  The
salinity samples from the piggyback bottle were used for comparison with
the Gerard barrel salinities to verify the integrity of the Gerard sample.
The identifiers of the sample containers and the numbers of the ODF or
Piggyback samplers from which the samples were drawn were recorded on the
Sample Log sheet.  Normal ODF sampling practice is to open the drain valve
before opening the air vent to see if water escapes, indicating the
presence of a small air leak in the sampler.  This observation ("air
leak"), and other comments ("lanyard caught in lid", "valve left open",
etc.) which may indicate some doubt about the integrity of the water
samples were also noted on the Sample Log sheets.  These comments are
included in this documentation with investigative comments and results.

The discrete hydrographic data were entered into the shipboard data system
and processed as the analyses were completed.  The bottle data were brought
to a usable, though not final, state at sea.  ODF data checking procedures
included verification that the sample was assigned to the correct depth.
This was accomplished by checking the raw data sheets, which included the
raw data value and the water sample bottle, versus the sample log sheets.
The salinity and nutrient data were compared by ODF with those from
adjacent stations.  Any comments regarding the water samples were
investigated.  The raw data computer files were also checked for entry
errors that could have been made on the station number, bottle number
and/or sample container number.  The salinity and nutrient values were
transmitted from PC's attached to either the salinometer or Autoanalyzer
system.

Investigation of data included comparison of piggyback salinities versus
Gerard salinities, and review of data plots of the station rosette data
profile.  If any problem was indicated, the data value was flagged.  The
Quality Comments includes comments regarding missing samples and
investigative remarks for comments made on the Sample Log sheets, as well
as all flagged (WOCE coded) data values other than 2, an acceptable
measurement.

The WOCE codes were assigned to the water data using the criteria:

code 1 =  Sample for this measurement was drawn from water bottle, but
          results of analysis not yet received.

code 2 =  Acceptable measurement.

code 3 =  Questionable measurement.  Does not fit station profile or
          adjoining station comparisons. No notes from analyst indicating a
          problem.  Datum could be real, but the decision as to whether it
          is acceptable will be made by a scientist rather than ODF's
          technicians.

code 4 =  Bad measurement.  Does not fit station profile and/or adjoining
          station comparisons.  There are analytical notes indicating a
          problem, but data values are reported.  ODF recommends deletion
          of these data values.  Analytical notes for salinity may include
          large differences between the piggyback and Gerard sample.
          Sampling errors are also coded 4.

code 9 =  Sample for this measurement not drawn.

Quality flags assigned to parameter BTLNBR (bottle number) as defined in
the WOCE Operations manual are further clarified as follows:

code 4 =  If the bottle tripped at a different level than planned, ODF
          assigned it a code 4.  If there is a 4 code on the bottle, and 2
          codes on the salinity, oxygen and nutrients then the pressure
          assignment was probably correct.

code 3 =  An air leak large enough to produce an observable effect on a
          sample is identified by a 3 code on the bottle and 4 code on the
          oxygen.  (Small air leaks may have no observable effect, or may
          only affect gas samples).

The following table shows the number of ODF samples drawn and the number of
times each WOCE sample code was assigned.

1.  Pressure and Temperature

LVS pressures and temperatures were calculated from deep-sea reversing
thermometer (DSRT) readings.  Each DSRT rack normally held 2 protected
(temperature) thermometers and 1 unprotected (pressure) thermometer.
Thermometers were read by two people, each attempting to read a precision
equal to one tenth of the thermometer etching interval.  Thus, a
thermometer etched at 0.05 degree intervals would be read to the nearest
0.005 degrees.

Each temperature value reported on the LVS casts is calculated from the
average of four readings provided both protected thermometers function
normally.  The pressure is verified by comparison with the calculation of
pressure determined by wireout.  The pressure from the thermometer is
fitted by a polynomial equation which incorporates the wireout and wire
angle.

Calibration of the thermometers are performed in ODF's calibration facility
depending on the age of the thermometer and not more than two years of the
expedition.

The temperatures are based on the International Temperature Scale of 1990.


2.  Salinity Analysis

Salinity samples were drawn into 200 ml Kimax high alumina borosilicate
bottles after 3 rinses, and were sealed with custom-made plastic insert
thimbles and Nalgene screw caps.  This assembly provides very low container
dissolution and sample evaporation.  As loose inserts were found, they were
replaced to ensure a continued airtight seal.  Salinity was determined
after a box of samples had equilibrated to laboratory temperature, usually
within 8-12 hours of collection. The draw time and equilibration time, as
well as per-sample analysis time and temperature were logged.

A single Guildline Autosal Model 8400A salinometer (Serial Number 57-396)
located in a temperature-controlled laboratory was used to measure
salinities. The salinometer was modified by ODF and contained interfaces
for computer-aided measurement. A computer (PC) prompted the analyst for
control functions (changing sample, flushing) while it made continuous
measurements and logged results.  The salinometer cell was flushed until
successive readings met software criteria for consistency, then two
successive measurements were made and averaged for a final result.

The salinometer was standardized for each cast with IAPSO Standard Seawater
(SSW) Batch P-120, using at least one fresh vial per cast.  The estimated
accuracy of bottle salinities run at sea is usually better than 0.002 PSU
relative to the particular Standard Seawater batch used.  PSS-78 salinity
(UNESCO 1981) was then calculated for each sample from the measured
conductivity ratios, and the results merged with the cruise database.

300 salinity measurements were made and 18 vials of standard water were
used.  The temperature stability of the laboratory used to make the
measurements was good.  There were some problems with lab temperature
control throughout cruise; the Autosal bath temperature was adjusted
accordingly.  Salinities were generally considered good for the expedition
despite the lab temperature problem.  Salinity samples were analyzed for
the Large Volume casts from both the piggyback bottle and the Gerard
barrel.


3.  Nutrient Analysis

Nutrient samples were drawn into 45 ml high density polypropylene, narrow
mouth, screw-capped centrifuge tubes which were rinsed three times before
filling.  Standardizations were performed at the beginning and end of each
group of analyses (one station, usually 18 samples) with a set of an
intermediate concentration standard prepared for each run from secondary
standards.  These secondary standards were in turn prepared aboard ship by
dilution from dry, pre-weighed primary standards.  Sets of 5-6 different
concentrations of shipboard standards were analyzed periodically to
determine the deviation from linearity as a function of concentration for
each nutrient.

Nutrient analyses (phosphate, silicate, nitrate and nitrite) were performed
on an ODF-modified 4 channel Technicon AutoAnalyzer II, generally within
one hour of the cast.  However, on LVS cast, samples for the Gerard barrels
were analyzed for silicate only as an added check (with salinity) on barrel
sample integrity.  Occasionally some samples were refrigerated at 2 to 6
degree C for a maximum of 4 hours.  The methods used are described by
Gordon et al. (1992), Atlas et al. (1971), and Hager et al. (1972).

All peaks were logged manually, and all the runs were re-read to check for
possible reading errors.

Silicate is analyzed using the technique of Armstrong et al.  (Armstrong
1967).  Ammonium molybdate is added to a seawater sample to produce
silicomolybdic acid which is then reduced to silicomolybdous acid (a blue
compound) following the addition of stannous chloride. Tartaric acid is
also added to impede PO4 contamination.  The sample is passed through a 15
mm flowcell and the absorbence measured at 820nm. ODF's methodology is
known to be non-linear at high silicate concentrations (>120 uM); a
correction for this non-linearity is applied in ODF's software.

Modifications of the Armstrong et al.  (1967) techniques for nitrate and
nitrite analysis are also used.  The seawater sample for nitrate analysis
is passed through a cadmium column where the nitrate is reduced to nitrite.
Sulfanilamide is introduced, reacting with the nitrite, then
N-(1-naphthyl)ethylenediamine dihydrochloride which couples to form a red
azo dye. The reaction product is then passed through a 15 mm flowcell and
the absorbence measured at 540 nm.  The same technique is employed for
nitrite analysis, except the cadmium column is not present, and a 50 mm
flowcell is used.

Phosphate is analyzed using a modification of the Bernhardt and Wilhelms
(1967) technique. Ammonium molybdate is added to the sample to produce
phosphomolybdic acid, then reduced to phosphomolybdous acid (a blue
compound) following the addition of dihydrazine sulfate. The reaction
product is heated to 55 degree C to enhance color development, then passed
through a 50 mm flowcell and the absorbence measured at 820 nm.

Nutrients, reported in micromoles per kilogram, were converted from
micromoles per liter by dividing by sample density calculated at zero
pressure, in-situ salinity, and an assumed laboratory temperature of 25
degree C.

Na2SiF6, the silicate primary standard, is obtained from Fluka Chemical
Company and Fischer Scientific and is reported by the suppliers to be >98%
pure.  Primary standards for nitrate KNO3, nitrite NaNO2, and phosphate
KH2PO4, are obtained from Johnson Matthey Chemical Co. and the supplier
reports purities of 99.999%, 97%, and 99.999%, respectively.

152 nutrient (Silicate) analyses were performed. No major problems were
encountered with the measurements.

D.  WHPO SUMMARY

Several data files are associated with this report. They are the p17c.sum, 
p17c.hyd, p17c.csl and *.wct files. The p17c.sum file contains a summary of the 
location, time, type of parameters sampled, and other pertient information 
regarding each hydrographic station. The p17c.hyd file contains the bottle data. 
The *.wct files are the ctd data for each station. The *.wct files are zipped 
into one file called p17cwct.zip. The p17c.csl file is a listing of ctd and 
calculated values at standard levels.

The following is a description of how the standard levels and calculated values 
were derived for the p17c.csl file:

Salinity, Temperature and Pressure: These three values were smoothed from the 
individual CTD files over the N uniformly increasing pressure levels using the 
following binomial filter-

          t(j) = 0.25ti(j-1) + 0.5ti(j) + 0.25ti(j+1) j=2....N-1

When a pressure level is represented in the *.csl file that is not contained 
within the ctd values, the value was linearly interpolated to the desired level 
after applying the binomial filtering.

Sigma-theta(SIG-TH:KG/M3), Sigma-2 (SIG-2: KG/M3), and Sigma-4(SIG-4: KG/M3): 
These values are calculated using the practical salinity scale (PSS-78) and the 
international equation of state for seawater (EOS-80) as described in the Unesco 
publication 44 at reference pressures of the surface for SIG-TH; 2000 dbars for 
Sigma-2; and 4000 dbars for Sigma-4.
Gradient Potential Temperature (GRD-PT: C/DB 10-3) is calculated as the least 
squares slope between two levels, where the standard level is the center of the 
interval. The interval being the smallest of the two differences between the 
standard level and the two closest values. The slope is first determined using 
CTD temperature and then the adiabatic lapse rate is subtracted to obtain the 
gradient potential temperature. Equations and Fortran routines are described in 
Unesco publication 44.

Gradient Salinity (GRD-S: 1/DB 10-3) is calculated as the least squares slope 
between two levels, where the standard level is the center of the standard level 
and the two closes values. Equations and Fortran routines are described in 
Unesco publication 44.

Potential Vorticity (POT-V: 1/ms 10-11) is calculated as the vertical component 
ignoring contributions due to relative vorticity, i.e. pv=fN2/g, where f is the 
coriolius parameter, N is the bouyancy frequency (data expressed as radius/sec), 
and g is the local acceleration of gravity. 

Bouyancy Frequency (B-V: cph) is calculated using the adiabatic leveling method, 
Fofonoff (1985) and Millard, Owens and Fofonoff (1990). Equations and Fortran 
routines are described in Unesco publication 44.

Potential Energy (PE: J/M2: 10-5) and Dynamic Height (DYN-HT: M) are calculated 
by integrating from 0 to the level of interest. Equations and Fortran routines 
are described in Unesco publication, Processing of Oceanographic station data, 
1991.

Neutral Density (GAMMA-N: KG/M3) is calculated with the program GAMMA-N (Jackett 
and McDougall) version 1.3 Nov. 94. 

    


E.  DATA QUALITY EVALUATIONS

E.1  DQE OF CTD DATA FOR TUNES LEG 1 WOCE P17C
     (Robert Millard)
     January 26, 1995

GENERAL:

The data quality of the CTD data of the individual 2-decibar CTD profiles and 
the CTD salinity and oxygen found in the water sample file are examined. The 
individual 2 decibar profiles were checked for glitches in temperature, salinity 
and oxygen by comparing individual profiles against one of two average profiles; 
the first average is of the East-West section and involving stations 6 through 
17 and the second station grouping is the North-South section involving stations 
18 through 123. The average profiles include standard deviation of temperature, 
salinity and oxygen which when scaled (default edit factor is 5.0 times the 
standard deviation) become the edit criteria for flagging questionable data. The 
stability parameter is also computed for observations within a profile and 
values less than a stability value (E = -5.0e-4 per meter) are also flagged. The 
stability edit criteria flags density inversions greater than .015 Kg/M3 per 
decibar. The screening of the entire 2 decibar data set against these edit 
criteria indicated the data to be free of spurious bad values in temperature, 
salinity and oxygen.

The CTD salinity (conductivity) and oxygen calibrations are checked using the 
water sample data file P17C.DQE. In comparing the CTD and water sample salinity 
and oxygen in the water sample file, only those data having a quality flag 
indicating a good measurement (ie values of 2) were used. The salinity and 
oxygen differences (CTD-Water Sample) are plotted in histogram form with 
salinity in figure 1 and oxygen figure 2. Salinity and oxygen differences are 
plotted versus station number in figures 3 and 4 and versus pressure in figures 
5a, 5b and 6. The plots versus pressure use expanded scales which don't show the 
extreme differences that occur in the upper few hundred decibars. The maximum 
salinity difference is .16 psu while the maximum difference of oxygen is 53.6 
micromoles/kg.

The deep water sample salinity and oxygen differences are also examined 
separately by further screening the good data (ie. quality value ="2") to 
exclude potential temperature values greater than 2.5 C. These comparisons are 
displayed in histograms of salinity and oxygen differences (figures 7 & 8) plus 
plots of the salinity and oxygen differences versus station number in figures 9 
and 10 respectively. The CTD salinity and oxygen of the water sample file are 
found to be well matched to the water samples over the cruise.


DETAILS:

EVALUATION OF CTD CALIBRATIONS TO WATER SAMPLES:

SALINITY:
The histogram of salinity differences for all depths (figure 1) shows a symetric 
distribution. The standard deviation is fairly large at 0.010 psu but 149 of a 
total of 3723 good salinity values that have a difference exceeding ±.02 psu. 
All of these large differences are shallower than 320 decibars and if excluded 
decrease the standard deviation to .0041 psu. The histogram of salinity 
differences for potential temperatures below 2.5 C (figure 7) has a mean 
difference of -0.00015 psu and a much smaller standard deviation of .0016 psu. 
The histogram of deep salinity differences is fairly normally distributed with a 
scatter that probably represents the uncertainty of the water sample salinity 
data. All good values of the salinity differences are plotted versus station in 
figure 3 and show no station dependent variations over the cruise. The 
distribution of salinity differences versus pressure (figure 5a) hints that the 
CTD salinity has a trend towards slightly saltier values as depth increases. The 
salinity differences below 2.5 C are displayed on an expanded scale in figure 5b 
to make this slight pressure dependence more obvious. A least squares regression 
line found on figure 5b indicates the pressure dependence is about .001 psu per 
1500 decibars. The plot of deep salinity differences versus station shown in 
figure 9 suggests a small station dependent variations of about ±0.001 psu in 
several 10 to 20 station groups. For example, the section of data between 
stations 43 and 57 appears to show the CTD salinity slightly salty at 43 and 
drifts to a slightly fresh value by station 57. An expanded scale plot is made 
for stations 43 to 57 (figure 11) that better shows the station drift as does 
the line indicating the least squares fit. This drift is reinforced by plots of 
potential temperature versus salinity for the two four station groups plots 
including stations 43 and 57. Figure 12 has salinities of stations 42, 43, 44, 
and 45 for both the 2 decibar CTD and water sample files. The water sample 
salinities (squares) are fresher [below 1.3 C) than CTD salinities of either the 
2 decibar (down) or water sample file CTD salinity (up). Figure 13 showns 
stations 54, 55, 56, and 57 nown the water sample salinities (squares) on the 
salty side of the CTD salts (both down and up). The magnitude of these salinity 
drifts are small (±0.001 psu) but they are systematic. Figure 9 shows a hint of 
this behavior in two other stations groups (stations 60 through 78) and perhaps 
stations 20 through 30 but no close examination was made.

OXYGEN:
The distribution of oxygen differences at all depths shown in the histogram of 
figure 2 indicates a well behaved fairly random distribution. The standard 
deviation of oxygen differences for all levels is 4.47 micromole/kg. The 
histogram of oxygen differences for potential temperatures below 2.5 C is 
tighter with a standard deviation of 1.12 Um/kg. The plot of oxygen differences 
for all good oxygens versus station in figure 4 has no suggestion of a station 
dependence. The largest oxygen difference is 53.6 micromoles/kg and 63 oxygen 
differences of a total of 3220 good oxygen comparisons exceed 15 microMoles/kg. 
All are shallower than 455 decibars. The plot of oxygen differences versus 
pressure (figure 6) shows that the CTD oxygen differences are well behaved in 
the vertical. Figure 6 uses expanded scales that excludes oxygen differences 
greater than ±15 micromoles/kg. The distribution of deep oxygen differences 
versus station in figure 10 are devoid of any station dependence trends. The CTD 
oxygen calibrations for this data set are excellent.

Comparison 2-dbar stations to Mean profile: Stations 1 to 17- East-West
The data quality of the 2 decibar CTD data for the East-West section compares 
well to the mean profile. A few of the shallow oxygen levels of the coastal 
stations (1 and 2) are flagged as questionable even with a large (10 standard 
deviation) edit criteria. A check of the water sample data indicates that these 
oxygens are fine and the problem resides with using the East-West mean profile 
in the coastal region.

Comparison 2-dbar stations to Mean profile Sta 18 to 123: North-South section
Comparing the individual salinity, temperature and oxygen values against an edit 
criteria of 5 standard deviations from the mean profile of stations 18 through 
123, no data errors were incountered for any of the station files listed below. 
The individual profiles were also tested for density instabilities using a 
minimum stability parameter value of -1.0 E-5. This amounts to a density 
inversion of .015 kg/M3 per decibar.

SUMMARY:
On the whole, WOCE section P17C represents a model CTD data set. The Tunes leg 1 
CTD data set is well calibrated in salinity at the ±0.001 psu level and the CTD 
oxygen calibration is excellent. There is a suggestion of a pressure dependence 
to the CTD salinity (conductivity) with the CTD becoming increasingly salty with 
increasing pressure by roughly .001 psu per 1500 decibars which should be 
examined. This is about the magnitude of the conductivity cell pressure 
deformation correction. There is a hint of a drift in the salinity differences 
below 2.5 C that should be checked out. The 2 decibar profiles are free of 
spurious data gliches. The Chief Scientists cruise report has a very useful 
discussion of the CTD instrument calibration results. There is mention of a 
follow up report that ODF is writing on the CTD calibrations but I have not seen 
it.

E.2  COMMENTS ON DQ EVALUATION OF TUNES LEG I (P17C) HYDROGRAPHIC DATA
     (A. Mantyla)
     2 November 1993

Aside from suffering some lost data due to trip malfunctions common to CTD-
Rosette casts, the sampling density and data quality of this cruise are quite 
good. The TUNES Leg I data are comparable to the TPS-24 cruise, and are better 
than most of the limited nearby historical data. The TUNES silicate, phosphate, 
and perhaps salinity tend to be lower than other cruises while the oxygen and 
nitrate data agree well. I expect the most recent data set to be the most 
reliable. The TUNES Leg I cruise track at 135°W helps to fill in a data sparse 
series of Marsden Squares in the Pacific and will certainly improve the Pacific 
deep data array.

The data originators have done a very meticulous job in evaluating the data and 
in solving trip problems, but they may have been overly zealous in flagging data 
that merely looked "funny" as "bad" data. Nutrients in particular, that were 
within the hoped for 1% of full scale accuracy range, were often flagged. In 
those cases, it is entirely possible that the flagged data could be closer to 
correct, and the accepted data slightly in error. However, I understand the 
desire to have an internally consistent data set and have not changed many of 
the flags.

Double trips, delayed trips and other mis-trips were frequent in the first 1/4 
of the cruise and most trip problems have been resolved. I've noted a few other 
possible trip depth assignment errors below that if corrected, would change the 
data quality flags from "bad" or "questionable" to "good data". On some 
stations, a large number of bottles were flagged "4" (did not trip correctly) 
due to mis-trips or double-trips causing subsequent planned trips to be off by 
one or more target depths. Comparisons of the water sample salinity and oxygen 
measurements with the CTDO info is usually sufficient to match the correct CTD 
trip data to the water sample data with a reasonable degree of certainty, and 
the data originators have done that quite well for this cruise. I have not 
changed any of the "4" flags, although I believe that most should NOT be flagged 
"did not trip correctly" for the following reason: the initial mis-trip or 
double-trip represents a missed planned sampling depth and could even be a trip 
between planned depths and should be flagged as a problem. However, the 
subsequent trips are usually routine or normal, except that the initial CTD 
information assigned to the trip is incorrect. Once the correct trip info has 
been aligned with the water sample data, there really is little question as to 
the correctness of the data, and those levels should be accepted as OK rather 
than to leave doubt about the data by using the "4" bottle code.

The deep water salinity data early in the cruise bounced around a little more 
than one would expect from good salinometer operation, but settled down as the 
cruise progressed. Between stations 48 and 77, bottle 22 was strangely low in 
salinity 19 out of 29 stations, initially by about .012 and finally by about 
.022 for stations 73 to 77. Yet, the oxygen and nutrient data appeared to be 
fine. I don't know of anything that could affect the salinity in the low 
direction and not affect the other measurements. At any rate the problem went 
away once the bottle was finally replaced.

Many bottle oxygens were flagged as bad or questionable based on comparisons 
with the CTD O2, as if the CTD O2 data were perfect. I doubt that it is, and 
apparently ODF does not consider it good enough to report with the bottle data. 
They should make an effort to do so, as most other organizations are satisfying 
the WOCE reporting expectations of including the CTD oxygen data. If the UP 
water sample O2's are being evaluated against the down CTD O2 data, that may not 
be appropriate because of occasional real water mass changes between down and up 
casts and particularly in active interfingering of shallower layers that was 
common on this cruise. Some O2 data had been flagged bad even when it agreed 
with the CTD O2(!), usually when the comment "air leak" appeared on the sample 
log sheet. An air leak may well affect gas samples, but if it is at the level 
beyond the last reported significant figure, that should not be reason to flag 
the O2 data as "bad".

Some of the nutrient problems probably could be resolved by careful evaluation 
of standards and blanks or possible shifts in machine response (PO4), but the 
effort probably would not be worth the return in a few improved nutrient 
stations at this stage.

The following are some specific problems that should be looked at:

STATIONS 1 and 2: 
Bottle salts average .008 less than CTD, yet the data comments form ODF indicate 
no difference at 303db and 353db. Station 2: The dot sea file shows a difference 
of .0070 and .0058. Is there a problem with the final CTD data here? Or was it a 
poor salinometer run? Discrepancy needs to be resolved.

STATION 6: 
Initial hang-up at bottle 34 caused bottles 14 and 34 to trip one depth 
shallower than intended. All flagged "4", "Did not trip correctly". Actually, 
CTD verifies trip levels, all except possibly 34 and 30 tripped OK. Suggest 
using "4" code at 34 and 30, accept others as good.

STATION 7: 
#31 at 3034db: Salinity and $0 sub 2$, flagged questionable, appear to belong 1 
depth shallower. Nutrients would fit there also. Suggest moving the data to 
2849db and flag the data OK.

STATION 8: 
249db and 354db: water samples deleted because of mis-trips. ODF data comments 
lists original analyses for the two depths identical to the last decimal place. 
Is that true? Not likely for 2 non-adjacent mis-trips. Recheck deleted data.


STATION 11: 
3401db: Looks like data belongs 1 level up at missed unlisted depth of 3145db. 
If done, remove uncertain flag from O2.

STATION 12: 
As on station 6, bottles 13-34 tripped 1 planned level off, but CTD verifies 
correct depths. Suggest flag bottles OK, except for #20 and #29, use "4" code.

STATIONs 15: 
Bottle 31 at 3963db flagged "u", but would be OK at next planned level up at 
3706db (not listed), as would salinity and nutrients. Suggest change and flag 
bottle "4", data OK. #33 and #34, 4477db and 4730db: nearly identical nutrients 
and salinity, O2 close. Most likely both tripped at same depth. #34 has hung-up 
on previous stations, so suggest move to 4477db. If not, flag silica "u".

STATION 23: 
Bottle 34 at 4268db data flagged "u", but is same as data at 4067db. Suggest 
move bottle 34 one depth up and accept data as OK, bottle "4 flag".

STATION 34: 
Deepest 3, 4276-4650db, clearly bad, must be titration or pickling error. 
Suggest omit. Curiously, these were flagged only "questionable", while O2 at 
3297db, only slightly off, was flagged "bad".

STATION 44: 
#18 and #36, 1011db and 5348db: O2's are identical, 173.3mm, both bad. Could 
there be some data recording error? If no error found, recommend deleting O2 at 
1011db.

STATION 84: 
Bottles 12, 2-11 (0-352db) flagged "4 did not trip correctly". Ramp shift 
probably offset, but CTD verifies correct trip depths, there is no uncertainty. 
Suggest change flags to OK (2).

STATION 86: 
First 12 bottles, as on 84. Accept as OK.

STATION 98: 
Cast 2, 36 fully sampled depths; and cast 4, 11 salinity and O2 checks only, are 
merged together. They should not be merged as they are entirely separate 
profiles. List the casts separately.



E.2.1  RESPONSE TO DQ EVALUATION OF TUNES LEG 1 (P17) HYDROGRAPHIC DATA
       (Lynne D. Talley and Mizuki Tsuchiya)
       June 15, 1994

Bottle flags: The operations manual states that a flag of "4" means that the 
bottle did not trip correctly. Using perphas the incorrect impression that if 
there had been any problem with tripping that the bottle should be flagged "4" 
even if it was felt that the correct tripping depth had been identified. Since 
this assumption seems to be incorrect many of the bottle flags "4" should be 
changed to "3".

Salinity at bottle 22: In the orginal report to the WHPO a note was included 
concering the salinities from station 48, bottle 22 to station 77 are slightly 
suspicious. This does indeed seem odd, and Arnold Mantyla confirmed that the 
values are "strangely low" and that this is odd. Not all bottle 22 salts are 
flagged, but the majority are between stations 48 and 77:

STATION 1 salinity: 
Although the station is listed in the DQE comments, there is actually no 
question listed there for station 1, so no response.

STATION 2 salinity: 
yes, the DQE is correct; the offsets at 303 and 353 db are really -0.007 and -
0.006. No change to flags in sea file. The documentation should be changed to 
reflect this. Here is the corrected text for station 2, in section D (Bottle 
data comments):

STATION 002

113  Bottle was closed but not intended as a sample. NBs 14 thru 17 were open as 
intended and ramp shaft in correct position. Water samples same as NB36 so 
assume NB 13 closed at first trip. This level is not reported.
129 @ 303db  Sample Log: "Air vent open" Delta-S -0.007 at 303db, in line with 
all other offsets on this station. O2 agrees with CTDO.
130 @ 353db  Sample Log: "Air vent open" Delta-S -0.006 at 353db, in line with 
all other offsets on this station. O2 agrees with CTDO.

STATION 6: 
mostly agree with DQE except for bottle 12. i.e. 6/1/30: bottle flag 4; 6/1/34: 
bottle flag 4; 6/1/12: bottle flag should be kept at 3 since "bottom cap knocked 
open"; 6/1/13-33 except 30 and 34: bottle flag 2

STATION 7: 
agree with DQE - change as requested i.e. 7/1/30 and 7/1/31: move salt, oxygen, 
nutrients from level 31 (3033) up to level 30 (2849 db) and flag as OK.

STATION 8: 
the 249 dbar values in the doc file are in error. They should read "Delete 
salinity (34.209), oxygen (2.3700), no3 (36.4), po4 (2.70), sio3 (97.5), no2 
(0.00)." They have been changed in the new documentation.

STATION 008

110 @ 249db  Sample log: Leaker. Delta-S .17 high at 249db. Nutrients also 
appear to be from deeper water. O2 looks ok. Delete salinity, o2, sil, no3, no2, 
po4, 
34.209  2.37  97.5  36.4  0.00  2.70, respectively.

STATION 11: 
The measured salinity at bottle 31 is 34.667. The CTD salinity at 3401 is 
34.669. The CTD salinity at 3145 is 34.663. The difference between measured and 
CTD salts for other bottles near this is on the order of -0.001 and -0.003. Thus 
increasing this difference to -0.006 by shifting the values to 3145 does not 
seem justified.

STATION 12: 
agree with DQE - change as requested i.e. 
6/1/13-34: change bottle flag to 2 except for 
6/1/20, 6/1/29: keep bottle flag of 4

STATION 15 
It is true that shifting bottle 31 from 3962 db to 3706 db would not be a 
problem with respect to salinity (it would actually slightly improve the 
difference between CTD and bottle salinity). The change in potential temperature 
is slight but enough that the oxygen seems to fit a bit better at 3706 than at 
3962. The nutrients fit pretty well at either pressure and theta. There is a 
slight improvement to oxygen; the nutrients fit alright at both 3962 and 3706. 
We could therefore go either way - in our own version of the file, we will not 
change anything about bottle 31 unless the WHPO makes a decision to change the 
values.

                      ctdprs  theta   ctdsal   bottlesal
                      ------  ------  -------  ---------
                      3706    1.4824  34.6761  34.6768
                      3962    1.4810  34.6786  34.6768


Thus we could have the following entry in the sea file:

15 1 31 31 3706.0 1.4824 34.6761 1.1954 34.6768 136.9 165.48 37.34 0.00 2.58 42222222


This is based on the 2dbar CTD data, since I don't have the raw CTD data here. 
If you would like this to be more refined, I can go back to ODF>

For station 15, bottle 34: change all CTD to same as bottle 33 at 4477, as 
suggested by DQE.

STATION 23: 
agree with DQE - change as requested, i.e. change all bottle 34 CTD data to be 
the same as bottle 33, no flags.

STATION 34: 
We assume that the DQE means only the oxygen values in the statement as the 
other parameters seem OK to us. Change as requested because values are truly 
terrible (all about 0 oxygen near the bottom).

STATION 44: 
The oxygen values at 1011 db and 5348 db had already been flagged as "4" 
(44/1/18 and 44/1/36)

STATION 84: 
agree with DQE - change bottle flags 84/1/12, 2-11 to 2 as requested

STATION 86: 
agree with DQE - change bottle flags as requested 86/1/12, 1-11 as requested.

STATION 98: 
agree with DQE - change as suggested. I believe that the latest version of this 
file which you received had these two casts separated (but I could be wrong).

Additional list of QUALT2 suggestions (DQE said that he has not listed many 
changes to "4" here - they are in the discussion above, so complete list should 
include above comments):

E.3.  CFC Data Quality Evaluation (DQE) on P17C 
      (F. A. Van Woy)
      January 13, 1995


We recently ftp'd the quality word changes that I made for Tunes leg 1, Pl7C. I 
believe that a reasonable assessment has been done. If the data originator 
wishes that I reconsider my choices, I will need to be provided with the 
following:

1)  CFC air concentrations for each station
2)  Calibration curves used for calculations
3)  Chromatograms
4)  Sample blanks applied and how determined
5)  Stripper efficiency results
6)  Contour plots

It is recommended on future cruises that the observer draw and run more 
replicate samples along with running more deep "blank" samples to assess the 
sample blank more thuroughly.

I believe that a reasonable quality assessment of the data has been done without 
the above items and any additional effort would take a fairly intensive 
involvement from this laboratory.

E.4.  Final CFC Data Quality Evaluation (DQE) Comments on P17C
      (David Wisegarver)
      Dec 2000

During the initial DQE review of the CFC data, a small number of samples were 
given QUALT2 flags which differed from the initial QUALT1 flags assigned by the 
PI. After discussion, the PI concurred with the DQE assigned flags and updated 
the QUAL1 flags for these samples.

The CFC concentrations have been adjusted to the SIO98 calibration Scale (Prinn 
et al. 2000) so that all of the Pacific WOCE CFC data will be on a common 
calibration scale.

E.5.  P17C TUNES-1  Final Report for Large Volume Samples
      (Robert M. Key)
      July 1, 1996

1.0   GENERAL INFORMATION

WOCE section P17C was the first in a series of three cruise legs collectively 
referred to as "TUNES". Mizuki Tsuchiya of SIO was chief scientist for this 
leg. This report covers details of data collection and analysis for the large 
volume Gerard samples. The reader is referred to "Documentation for WOCE 
Hydrographic Program section P17C" by L.D. Talley and M. Tsuchiya as the 
primary source for cruise information. Significant portions of this report 
(hydrography) were taken directly from a data report prepared by the 
Oceanographic Data Facility at Scripps Institution of Oceanography (dated 
July 17, 1995). Detailed text describing specific sample/bottle problems 
which were in the ODF report are reproduced here as an appendix.

Nine large volume (LV) stations were occupied on this leg. The cruise plan 
called for 2 Gerard casts of 9 barrels each at each LV station. The planned 
sampling density was 1 station every 5° of latitude (~300nmi). Each station, 
except for station 34, included at least one deep cast (2500db to the 
bottom), and an intermediate (1000db to 2500db) cast. In the event of 
mistripped Gerard sampler(s), casts were repeated as time allowed in an 
attempt to collect the full suite of samples. The purpose of these casts was 
to collect samples for 14C analysis. 14C coverage for the upper water column 
was done via small volume AMS sampling from the Rosette. This report covers 
only the large volume Gerard sampling.

All LV casts for the TUNES cruises were done using the stern A-frame on the R/V 
Thomas Washington. As is generally the case, the combination of a small vessel 
with working off the stern led to an elevated failure rate for the LV work 
relative to working off the side of a larger vessel. This problem is a result 
of accelerations on the trawl wire caused by ship motion and sea state. Slowing 
the lowering rate to 50 meters per minute or less reduced the failure rate. The 
Gerard barrel platform, as set up in port prior to the cruise, did not allow 
enough clearance for barrel deployment and recovery. The Chief Engineer cut the 
platform loose and rewelded it to the deck about one foot forward. The spring-
loaded trapping-pin was no longer usable so a chain was shackled to one forward 
corner of the platform, passed aft of the wire then hooked to the other forward 
corner to hold the trawl wire in the platform "V" while the barrels were being 
attached and detached. Limited fantail space and the low trawl wire lead 
required that the crane work over the wire to move barrels from racks to near 
the center-line just forward of the platform, then the barrel was unhooked and 
the crane moved to the other side of the wire and re-hooked to move the barrel 
to the attachment position. This procedure was reversed for recovery. Problems 
were minimized by the exceptional effort and capability of the Washington's 
crew. Table 1 summarizes the LV sampling.

Each Gerard barrel was equipped with a piggyback 5 liter Niskin bottle which 
had a full set of high precision reversing thermometers to determine sampling 
pressure and temperature. Both Gerard and Niskin were sampled for salinity. 
Additionally, each Gerard was sampled for silicate and radiocarbon. The 
salinity samples from the piggyback bottle were used for comparison with the 
Gerard barrel salinities to verify the integrity of the Gerard sample. 
Discrete sample information was recorded on a log sheet. Normal sampling 
practice is to open the Gerard drain valve before opening the air vent to see 
if water escapes, indicating the presence of a small air leak in the sampler. 
This observation ("air leak"), and other comments ("lanyard caught in lid", 
"valve left open", etc.) which may indicate some doubt about the integrity of 
the water samples were also noted on the log sheets. These comments are 
included in the appendix. The hydrographic data were entered into the 
shipboard data system and processed as analyses were completed. The bottle 
data were brought to a usable, though not final, state at sea. ODF data 
checking procedures included verification that the sample was assigned to the 
correct depth. ODF compared salinity and nutrient data with data from 
adjacent stations and with the rosette cast data from the same station. Any 
comments regarding the water samples were investigated. The raw data computer 
files were also checked for entry errors.

2.0  PERSONNEL

LV sampling for this cruise was under the direction of the principal 
investigator, Robert M. Key (Princeton). All LV 14C extractions at sea were 
done by Leonard Lopez (SIO-ODF). In addition to Key and Lopez, deck work was 
done by the SIO CTD group with assistance from many of the scientific party. 
Lopez was primarily responsible for reading thermometers. Salinities and 
nutrients were analyzed by the SIO CTD group and the Oregon State Univ. group 
respectively. 14C analyses were performed at Göte Östlund's laboratory (U. 
Miami, R.S.M.A.S.). Key collected the data from the originators, merged the 
files, assigned quality control flags to the 14C, rechecked the flags assigned 
by ODF and submitted the data files to the WOCE office (8/95).

3.0  RESULTS

This data set and any changes or additions supersedes any prior release. In 
this data set Gerard samples can be differentiated from Niskin samples by the 
bottle number. Niskin bottle numbers are in the range 41-50 while Gerards are 
in the range 81-94.

3.1  PRESSURE AND TEMPERATURE

Pressure and temperature for LV casts are determined by reversing 
thermometers mounted on the piggyback Niskin bottle. Each bottle was equipped 
with the standard set of 2 protected and 1 unprotected thermometer. Each 
temperature value reported on the LV casts was calculated from the average of 
four readings, provided both protected thermometers functioned normally. 
Reported temperatures are relative to the International Temperature Scale of 
1990. All thermometers, calibrations and calculations were provided by SIO-
ODF. Reported temperatures for samples in the thermocline are believed to be 
accurate to 0.01°C and for deep samples 0.005°C. Pressures were calculated 
using standard techniques combining wire out with unprotected thermometer 
data. In cases where the thermometers failed, pressures were estimated by 
thermometer data from adjacent bottles combined with wire out data. Because 
of the inherent error in pressure calculations and the finite flushing time 
required for the Gerard barrels, the assigned pressures have an uncertainty 
of approximately 10 dB. The pressures recorded in the data set for each 
Gerard-Niskin pair generally differ by approximately 0.5 dB with the Gerard 
pressure being the greater. This is because the Niskin is hung near the upper 
end of the Gerard.

3.2  SALINITY

A salinity samples was collected from each Gerard barrel and each piggyback 
Niskin bottle. Analyses were performed by the same personnel who ran the salt 
samples collected from the Rosette bottles so the analytical precision should 
be the same for LV salts and Rosette salt samples. When both Gerard and 
Niskin trip properly, the difference between the two salt measurements should 
be within the range 0.000 - 0.003 on the PSU scale. Somewhat larger 
differences can occur if the sea state is very calm and the cast is not 
"yoyo'ed" once the terminal wire out is reached. This difference is due to 
the flushing time required for the Gerard barrels and the degree of 
difference is a function of the salinity gradient where the sample was 
collected. In addition to providing primary hydrographic data for the LV 
casts, measured salinity values help confirm that the barrels closed at the 
desired depth. For the area covered by this leg, deep nutrient values 
(especially silicate) are as useful for trip confirmation as salt 
measurements due to the very low vertical gradient in salinity.

Salinity samples were drawn into 200 ml Kimax high alumina borosilicate 
bottles after 3 rinses, and were sealed with plastic insert thimbles and 
Nalgene screw caps. This assembly provides very low container dissolution and 
sample evaporation. As loose inserts were found, they were replaced to ensure 
a continued airtight seal. Salinity was determined after a box of samples had 
equilibrated to laboratory temperature, usually within 8-12 hours of 
collection. The draw time and equilibration time, as well as per-sample 
analysis time and temperature were logged.

A single Guildline Autosal Model 8400A salinometer located in a temperature 
controlled laboratory was used to measure salinities. The salinometer was 
standardized for each cast with IAPSO Standard Seawater (SSW) Batch P-114, 
using at least one fresh vial per cast. The estimated accuracy of bottle 
salinities run at sea is usually better than 0.002 PSU relative to the 
particular Standard Seawater batch used. PSS-78 salinity (UNESCO 1981) was 
then calculated for each sample from the measured conductivity ratios, and 
the results merged with the cruise database. There were some problems with 
lab temperature control throughout cruise; the Autosal bath temperature was 
adjusted accordingly. Salinities were generally considered good for the 
expedition despite the lab temperature problem.

3.3  NUTRIENTS

Nutrient samples were collected from Gerard samples. On this leg silicate 
values were measured on all samples and phosphate on a few selected samples. 
LV nutrients were measured along with Rosette nutrients so the analytical 
precision for Gerard samples should be the same as Rosette samples. For some 
unknown reason, nutrients collected from LV casts are frequently subject to 
systematic offsets from samples taken from Rosette bottles. For this reason 
it is recommended that these data be viewed primarily as a means of checking 
sample integrity (i.e. trip confirmation). The Rosette-Gerard discrepancy is 
frequently less for silicate than for other nutrients.

Nutrient samples were drawn into 45 ml high density polypropylene, narrow 
mouth, screw-capped centrifuge tubes which were rinsed three times before 
filling. Standardizations were performed with solutions prepared aboard ship 
from preweighed chemicals; these solutions were used as working standards 
before and after each cast to correct for instrumental drift during analysis. 
Sets of 4-6 different concentrations of shipboard standards were analyzed 
periodically to determine the linearity of colorimeter response and the 
resulting correction factors.

Nutrient analyses were performed on a modified 4 channel Technicon 
AutoAnalyzer II, generally within one hour of the cast. Occasionally samples 
were refrigerated at 2 to 6°C for a maximum of 4 hours. The methods used are 
described by Gordon et al. (1992), Atlas et al. (1971), and Hager et al. 
(1972). All peaks were logged manually, and all the runs were re-read to 
check for possible reading errors.

Silicate was analyzed using the technique of Armstrong et al. (1967). ODF's 
methodology is known to be non-linear at high silicate concentrations (>120 
µM); a correction for this non-linearity was applied. Phosphate was analyzed 
using a modification of the Bernhardt and Wilhelms (1967) technique.

Na2SiF6, the silicate primary standard, was obtained from Fluka Chemical 
Company and Fischer Scientific and is reported by the suppliers to be >98% 
pure. Primary standards for phosphate, KH2PO4, were obtained from Johnson 
Matthey Chemical Co. and the supplier reports purity of 99.999%.

Nutrients, reported in micromoles per kilogram, were converted from 
micromoles per liter by dividing by sample density calculated at zero 
pressure, in-situ salinity, and an assumed laboratory temperature of 25°C.

152 nutrient (silicate) analyses were performed. No major problems were 
encountered with the measurements.

3.4  14C

Most of the _14C values reported here have been distributed in a data report 
produced by Östlund (1992). That report included preliminary hydrographic 
data and is superceded by this submission.

All Gerard samples deemed to be "OK" on initial inspection at sea were 
extracted for 14C analysis using the technique described by Key (1991). The 
extracted 14CO2 /NaOH samples were returned to the Ocean Tracer Lab at 
Princeton and subsequently shipped to Östlund's lab in Miami. Both 13C and 14C 
measurements are performed on the same CO2 gas extracted from the large volume 
samples (13C analyses at M. Stuiver's lab, U. Washington). The standard for 
the 14C measurements is the NBS oxalic acid standard for radio-carbon dating. 
R-value is the ratio between the measured specific activity of the sample CO2 
to that of CO2 prepared from the standard, the latter number corrected to a 
_13C value of -19 and age corrected from today to AD1950 all according to the 
international agreement. _14C is the deviation in  from unity, of the 
activity ratio, isotope corrected to a sample _13C value of -25. For further 
information of these calculations and procedures see Broecker and Olson 
(1981), Stuiver and Robinson (1974) and Stuiver (1980). Östlund's lab reports 
a precision of 4 for each measurement based on a long term average of 
counting statistics.

Of the 152 Gerard samples collected, 14C has been measured on 148 (97%). This 
exceeds the rate funded for this work (80%).

Existing 14C data for the area sampled on this cruise is limited to a few 
GEOSECS measurements. Comparison of these two data sets indicates that they 
are in agreement to the precision of the measurements.

4.0  DATA SUMMARY

Figures 1-3 summarize the large volume 14C data collected on this leg. All _14C 
measurements with a quality flag value of 2 are included in each figure. 
Figure 1 shows the _14C values plotted as a function of pressure for the 
thermocline region (1a) and for the deep and bottom waters (1b). One sigma 
error bars (±4) are shown in both 1a. and 1b. The most noticeable 
characteristic is the strong minimum in the 2000-2600dB range for all 
stations. Figure 2 show the _14C values plotted against measured Gerard barrel 
silicate values. The rather strong 14C-silicate correlation noted for the 
TUNES-3 (P16C) data is not so evident in Figure 2. Figure 3 is a coarse 
resolution machine contoured section of the 14C distribution in the deep and 
bottom waters for this leg. The minimum decreases in intensity and scope to 
the south and has an extreme value of -251. The "bi-lobed" nature of the -
240 contour is an artifact of the gridding routine.

6.0	QUALITY CONTROL FLAG ASSIGNMENT

Quality flag values were assigned to all bottles and all measurements using 
the code defined in Tables 0.1 and 0.2 of WHP Office Report WHPO 91-1 Rev. 2 
sections 4.5.1 and 4.5.2 respectively. In this report the only bottle flag 
values used were 2, 3, 4 and 9. For the measurement flags values of 2, 3, 4 
or 9 were assigned. The interpretation of measurement flag 9 is unambiguous, 
however the choice between values 2, 3 or 4 is involves some interpretation. 
For this data set, the salt and nutrient values were checked by plotting them 
over the same parameters taken from the rosette at the same station. Points 
which were clearly outliers were flagged "4". Points which were somewhat 
outside the envelop of the other points were flagged "3". In cases where the 
entire cast seemed to be shifted to higher or lower concentrations (in 
nutrient values), but the values formed a smooth profile, the data was 
flagged as "2". The few phosphate measurements which were made on these 
samples are all flagged "4". Comments are given in the next section for flag 
values of 3 or 4 in almost all cases. Once the nutrient and salt data had 
been flagged, these results were considered in flagging the 14C data. There is 
very little overlap between this data set and any existing 14C data, so that 
type of comparison was impractical. In general the lack of other data for 
comparison led to a more lenient grading on the 14C data.

When using this data set for scientific application, any 14C datum which is 
flagged with a "3" should be carefully considered. My subjective opinion is 
that any datum flagged "4" should be disregarded. When flagging 14C data, the 
measurement error was taken into consideration. That is, approximately one-
third of the 14C measurements are expected to deviate from the true value by 
more than the measurement precision of ~4.

No measured values have been removed from this data set. When using this data 
set, it is advised that the nutrient data only be considered as a tool for 
judging the quality of the 14C data regardless of the quality code value. A 
summary of all flags is provided in Table 2.

7.0  APPENDIX: Detailed Sample Notes

The following table lists comments recorded on the sample collection and 
thermometer sheets, and includes notes on sample flags provided by ODF. Any 
text in this listing shown in italics was added by the author in the final QC 
check which included the 14C data. The first column is the cast number 
(CASTNO) times 100 plus the bottle number (BTLNBR). In the comment field, 
"GB" or "G" stands for Gerard, "PB" refers to the piggyback 5 liter Niskin 
bottle and "N-G" is the arithmetic difference between the measured salinity 
values for a Niskin - Gerard pair.

               Gerard (94) may have leaked.  Gerard salinity is low,
               silicate looks reasonable.  Suspect there was a leak, let PI
               decide.

194 @4936db    Sample log: "Air vent open on return. Was definitely closed
               when deployed."  Gerard salinity is low, silicate looks

G.5  P17C TUNES-1 FINAL REPORT FOR AMS 14-C SAMPLES
     (Robert M. Key)
     July 2, 1996


1.0  GENERAL INFORMATION

WOCE section P17C was the first in a series of three cruise legs referred 
to as "TUNES". Mizuki Tsuchiya of SIO was chief scientist for this leg. 
This report covers details of data collection and analysis for the small 
volume radiocarbon samples. The reader is referred to "Documentation for 
WOCE Hydrographic Program section P17C" by L.D. Talley and M. Tsuchiya as 
the primary source for cruise information. Of 121 stations, 29 were sampled 
for radiocarbon. The AMS station locations are shown in Figure 1* and 
summarized in Table 1.

14-C samples were additionally collected for measurement by the large 
volume technique on 9 stations (17, 26, 34, 46, 57, 66, 76, 98 and 121). 
AMS sampling was used for the upper thermocline and large volume sampling 
for the deep and bottom waters. Results for the large volume samples are 
reported in Key (1996).

2.0  PERSONNEL

14-C sampling for this cruise was carried out by Robert M. Key (Princeton). 
14-C analyses were performed at the National Ocean Sciences AMS Facility 
(NOSAMS) at Woods Hole Oceanographic Institution. Salinities and nutrients 
were analyzed by the SIO CTD group and the Oregon State Univ. group 
respectively. Key collected the data from the originators, merged the files, 
assigned quality control flags to the 14-C and submitted the data files to 
the WOCE office (7/96).

3.0  RESULTS

This 14-C data set and any changes or additions supersedes any prior 
release.

3.1  HYDROGRAPHY

Hydrography from this leg have been submitted to the WOCE office by the 
chief scientist and described in the previously mentioned report.

3.2  14-C

Most of the Delta-14-C values reported here have been distributed in a data 
report (NOSAMS, 1994). That report included preliminary hydrographic data 
and 14-C results which had not been through the WOCE quality control 
procedures. This report supersedes any previous 14-C data distributions.

At this time 449 of 507 samples collected have been measured and reported. 
Replicate measurements were made on 8 of the samples. These replicate 
analyses are tabulated and summarized in Table 2. The table shows the mean 
and standard deviation for each set of duplicates. For these few samples, 
the average standard deviation is ±7.3 0/00. This precision estimate is 
approximately correct for the time frame over which these samples were 
measured. For a summary of the improvement in precision with time at 
NOSAMS, see Key, et al. (1996). In the final data reported to the WOCE 
office, the error weighted mean and the larger of the standard deviation 
and the error weighted standard deviation of the mean are given for 
replicate analyses.

4.0  QUALITY CONTROL FLAG ASSIGNMENT

Quality flag values were assigned to all 14-C measurements using the code 
defined in Table 0.2 of WHP Office Report WHPO 91-1 Rev. 2 section 4.5.2. 
Measurement flags values of 2, 3, 4, 6 and 9 have been assigned to date. 
Approximately 50 samples remain to be measured. Currently, the unmeasured 
samples are incorrectly coded with a flag value of 9 (no sample collected) 
rather than 1 (sample collected) or 5 (no result reported). The choice 
between values 2 (good), 3 (questionable) or 4 (bad) is involves some 
interpretation. There is very little overlap between this data set and any 
existing 14-C data, so that type of comparison was difficult. In general 
the lack of other data for comparison led to a more lenient grading on the 
14-C data.

When using this data set for scientific application, any 14-C datum which 
is flagged with a "3" should be carefully considered. My subjective opinion 
is that any datum flagged "4" should be disregarded. When flagging 14-C 
data, the measurement error was taken into consideration. That is, 
approximately one-third of the 14-C measurements are expected to deviate 
from the true value by more than the measurement precision. No measured 
values have been removed from this data set.

Table 3 summarizes the quality control flags assigned to this data set. For 
a detailed description of the flagging procedure see Key, et al. (1996c). 
As more of the Pacific data set becomes available, it is possible that some 
of these flag values may be modified. Any additional data received for this 
leg will be reported to the WOCE office as they become available.

5.0  DATA SUMMARY

Figures 2-4* summarize the AMS 14-C data collected on this leg. Only Delta-
14-C measurements with a quality flag value of 2 are included in each 
figure. Figure 2 shows the Delta-14-C values with 2sigma error bars plotted 
as a function of pressure for the upper two kilometers of the water column. 
The most noticeable characteristic is the broad spread of the data in the 
upper 500m. This is primarily due to shoaling of isopycnals in the 
equatorial zone. This figure also clearly demonstrates the sampling 
strategy used during the TUNES legs. That is, AMS sampling was almost 
totally limited to the upper 1500 meters of the water column. Large volume 
Gerard barrel sampling was used to cover the deep and bottom waters. This 
strategy was chosen primarily because the collection cost for AMS 14-C 
samples is significantly less than for the Gerard technique. At the time of 
this cruise, it was known that the AMS technique was less precise than the 
large volume technique, however Figure 2* clearly demonstrates that AMS 
precision is easily sufficient to resolve the vertical gradients in Delta-
14-C, at least in the upper kilometer.

Figure 3* shows the Delta-14-C values plotted against silicate for samples 
from the upper 2 kilometers of the water column. The straight line shown in 
the figure is the least squares regression relationship derived by Broecker 
et al. (1995) based on the GEOSECS global data set. According to their 
analysis, this line (Delta-14-C = -70 - Si) represents the relationship 
between naturally occurring radiocarbon and silicate for most of the ocean. 
They interpret deviations in Delta-14-C above this line to be due to input 
of bomb-produced radiocarbon. Clearly, this relationship is not ideal for 
the P17C data set. The points in Figure 3* fall into two distinct groups. 
The first group falls below the line for silicate concentrations greater 
than approximately 50mmol/kg then slopes sharply upward for lower silicate 
concentrations. The second group has fewer points, but generally has a 
linear trend across the plotted silicate concentration range and is 
significantly above and steeper than Broecker's relationship. The first 
data grouping is from stations which are south of ~20°N. For these data, 
the break in the trend (Delta-14-C ~-100 0/00; Si~40 µmol/kg) occurs at 
approximately the same location as CFC-11 goes to zero. While CFC-11 
concentration may not be as good an indicator as tritium, the data is 
consistent with the break point being the zone to which bomb-produced 
radiocarbon has penetrated.

Figure 4* is an objective section (LeTraon, 1990) of the Delta-14-C 
distribution for the upper kilometer of the water column (Station 17-121). 
Obvious in the figure are the doming of the isopleths near the Equator and 
the subsurface location of the maximum Delta-14-C concentration for most of 
the section.

Figure 3*: Delta-14-C as a function of silicate for P17C AMS samples. The 
           straight line shows the relationship proposed by Broecker, et al., 
           1995 (Delta-14-C = -70 - Si with radiocarbon in o/oo and silicate in 
           µmol/kg).

           portion of TUNES leg 1 (Stations 17-121; WOCE line P17C). Gridding

           the AMS technique (Key, 1996a,b; Key, et al., 1996). For most of the 
           section the maximum concentration is found below the surface.

sta/cast  Comments
--------  ----------------------------------------------------------------------
998/01    using CTD-1 from beginning of cruise. TEST cast: btls 20-36 all 
          tripped at 1000m; 3 additional btls tripped at 400m
124/01    repeat station 123 from leg 1
125/01
126/01
127/01
128/01    -.1 mmho/cm cond. spike at 148-152 db down; despiked/ok now
129/01    ABORT at 150m: sensor caps on/pinger off; data not saved
129/02    1-hr deploymt delay when rosette hit ship hard at initial launch: 
          weights knocked loose, CTD end clamp broken, other misc.breakage. No 
          cast# assigned to 2-minute first launch/data not used.
130/01    brief yoyo on down (15 to 12m) at base of T mixed-layer
131/01
132/02
133/01    frequent/high cond. noise (not drop-outs) on down from 810-1300 db, 
          again 1985-bottom; yoyo 50m back down after 2544 db trip to check 
          sensor response: problem occurs when P increases - cracked cell? yoyo 
          from 2546-2598 db up; 436,448,478 db levels interpolated: cutouts in 
          raw data signal.
134/01    replaced cond. cell with new spare prior to cast.
135/01    cond. problem may still be here, but smaller amplitude
136/01    cond. problem still here: maybe FSI temp board?
137/01    switch to CTD-2 beginning this cast
138/01
139/01
140/01
141/01
142/01    dipped into water before sensor covers removed/pinger on; trip inner 
          rosette first for freons
143/03
144/01
145/01
146/01    xmiss cleaned at start of cast
147/01
148/01    used PRT-1 for primary temperature during cast; used PRT-2 for final 
          data - see station 150 PRT comments
149/01    used PRT-1 for primary temperature during cast; used PRT-2 for final 
          data - see station 150 PRT comments
150/01    PRT-1 T offsets: +.7 deg at 528 db down and two smaller offsets. PRT-1 
          definitely sick; used PRT-2 for final data
151/01    CTD-10 starting here; trip detect only sees outer pylon: CTD data for 
          top 12 trips extracted manually

179/02    cast start delayed 10 mins. after rosette hit side of ship: one 
          lanyard broken/repaired, no other damage noted.
180/02    xmiss check (before or after cast?)
181/01
182/01    ABORT at 100m down: complete signal loss; CTD-10 flooded
182/02    back to CTD-1 w/orig. C-sensor, changed shielding around PRT-2 
          temperature interface. Cond. problem worse: shorten cast to 2000m/24 
          btls. Cond. noise has pressure-direction (down) dependence, up much 
          cleaner. -.2 mmho/cm cond. spike 252-254 db up: despiked/ok now. 
          Multiple spikes on up cast, most despiked/ok now. Some smaller cond. 
          noise still remains. Yoyo from 294-330 db up.
183/01    back to CTD-2 using PRT-2 for primary temperature. No inner-pylon 
          detect circuit in: CTD data for top 12 trips extracted manually. 
          Ctdoxy signal cutouts top 120 db. Two DSRTs added to each cast from 
          here to end of cruise to monitor PRT drifting problems.
184/01    still no inner-pylon detect, CTD data for top 12 trips extracted 
          manually; ctdoxy signal cutouts top 70 db
185/01    pylon detect for inner pylon installed; ctdoxy problem fixed: sensor 
          interconnect cable problem.
186/01
187/02    ctdoxy probe acting up till 1900 db down
188/01    new oxygen sensor; PRT-2 jumped; cond. seems ok
189/01    ABORT at 300m: CTD-2/PRT-2 + cond. jumping; PRT-1 locked up at 32767 
          (raw data)
189/02    ABORT at 300m - similar problems to cast 1
189/03    rebuilt CTD-2: CTD-2 card cage in CTD-1 Pressure case w/turret, PRT, 
          endcaps, A/D, digitizer, mmux, P/T/orig.C sensors from CTD-1: still 
          cond. noise: low-side S noise from CTD-1 moved to CTD-2? Ctdoxy sensor 
          malfunctioning, reads 20% of normal values; ctdoxy data not usable. 
          Delay 27 minutes at 15m down: computer problems.
190/01    CTD-2 cond. sensor interface board swapped in, ctdoxy sensor wires 
          swapped; using CTD-1 tty/fsk card; ctdoxy still not working - see cast 
          189/03. Cast delayed 15 minutes for cable/connector repairs. Yoyo from 
          2968-2978 db up.
191/01    CTD oxygen useless again: see cast 189/03
192/01    CTD oxygen useless again: see cast 189/03; pinger died near bottom
193/01    delay cast start 40 mins.: replaced CTD-1 cond sensor interface. 
          Replaced ctdoxy sensor w/old one: ok. Yoyo from 2632-2642 db up.
194/01    TEST cast to <600m using CTD-2 P-sensor interface: no effect.
194/02    TEST cast to <600m using CTD-10 T-sensor interface: no effect.
194/03    CTD-1 P/T sensor interfaces. Same cond. noise as before.
195/01    experiments w/winch speed vs. cond. noise on downcast
196/01    found loose FSI-T bulkhead connector, tightened it: changed, but did 
          not eliminate, cond. noise: some stable cond. areas.
197/01    replaced FSI bulkhead/cleaned cond. sensor guard: coating on PRT/cond. 
          guard peeling off: large sheet still attached to top of guard: 
          apparently flapped over cond. cell going down, flapped out of the way 
          going up. Removed coating from guard: no more cond. problem!
198/02
199/01
200/01
201/01
202/01
203/01    rosette lowered into bottom (+8m after btm trip): winch went the wrong 
          way; no damage, but bottom cond. spike cut off in p-series. 1418 db 
          level interpolated: cutout in raw data signal.
204/01    NEW END TERMINATION prior to cast; steep btm/side of seamount
205/01    problem w/winch or heave compensator from 15m to 2233m
206/01
207/01    steep bottom
208/01    yoyo from 17-4 db down
209/01    -.5 mmho/cm cond. spike (seasnot?) 1056-1070 db down: despiked/ok now
210/02
211/01    1-hr delay at cast start: dead signal in-water, immed. back out: slip 
          ring plug slipped/plugged back in and insulation repaired. Second 
          false- start when cast resumed before computer ready. Data from false 
          starts not saved.
212/01    heave-compensator disabled 15-260m down as a test
213/01    bad/high ctdoxy rdgs up: water leaked into sensor
214/01
215/01
216/01
217/01    rosette briefly out of water before srfc btl closed; lowered back in
218/01
219/01
220/01    descent delayed 5 mins. due to heave compensator

ÝNOTE:  pressure-series upcasts had an inverted elapsed time: 0 dbar times were 
        re-defined as 0, and other times were generated by subtracting averaged 
        time from averaged surface time. This required calculating entirely new 
        taus in order to fit the data.

          The next message (1000+ lines) contains the tritium-helium 
          data for the TUNES 2 leg. Just to reiterate, this is the Thomas 
          Washington cruise that took place in the summer of 1991, covering 
          Pl7c-Pl6c along 135W and 150W respectively. The data are organized 
          as one line per "sample", which may contain tritium, helium or 
          both. -99 represents no data or sample for a variable. The columns 
          are as follows:
          
          Sta, Cast, Bottle, Pressure (db), tritium (TU), sigma-tritium 
          (TU), delta-3He (permil), sigma-delta (permil), conc-Helium 
          (nM/Kg), sigma-conc (nM/Kg), quall, qual2
          
          The quality numbers for tritium (quall) are
            1 =  valid sample
            2 =  possible under-extraction
            3 =  possible contamination
            7 =  identity suspected
            9 =  no sample
          In this data set, there were no quall values of 2,3 or 7
          
          The quality numbers for helium (qual2) are
            1 =  valid sample
            2 =  possible under extraction
            3 =  possible (air) contamination
            7 =  identity suspected
            9 =  no sample 
          In this data set, there were no qual2 values of 7
          
          Also, the obvious applies, if a sample value is null (-99) its 
          error, which may not appear as null (-99) is meaningless.
          
          Also, the tritium data has been corrected for a small (.0045 TU) 
          blank due to cosmogenic production during storage.
          
          Finally, I was hoping to finish up a paper that I am working on 
          for this data: I don't mind you using it for demonstration 
          purposes, but-I would hope that its distribution could be 
          restricted over the next 4-5 months until I have had a chance to 
          get it submitted and hopefully reviewed and accepted. Also, it 
          will give me a chance to make one final pass at the data to ensure 
          that there are no problems with it. I hope this is OK.

          I just ftp'd our cfc files to the /INCOMING/RFine_cfcs directory.  
          The files named *.sea are hydro files with our final cfc values 
          and quality bytes merged in.  The files named *_cfcs.dat are files 
          that include station, cast, bottle, cfcs and quality bytes.  
          Please let me know if you have any problems and I'll let you know if 
          we have any changes (hopefully not...).

01/18/00  Key          DELC14 LV           Final Data Rcvd @ WHPO  
          forwarded to Sarilee for reformatting  You may have tons of questions 
          regarding the following. Hopefully I can answer most of them. I 
          have tried to pare this listing down to a minimum at this point.
          
          Attached are 5 ascii files and one pdf file for P17C LV 
          (a.k.a.TUNES-1):
          
          P17CLV.data - my version of the final data file with all qc flags 
          (this file has a temperature flag (tf) and a pressure flag (pf). The 
          appendix to this report contains all shipboard notes regarding sample 
          collection, problems, etc.
            P17CLV.sta - my version of the final LV station file 
            P17CLV.pdf - my final data report for P17C LV data
            31WTTUNES1.ldo - original LV report produced by SIO (Sanborn)
            31WTTUNES1.lsu - final version of p17c lv sum file
            31WTTUNES1.lvs - initial version of p17c lv hyd file (no C14 prior 
                             to my QC, but close to WOCE format and with all 
                             times and locations)
            AND
          
          5 ascii files and 1 pdf file for P17C LV (a.k.a. TUNES-3). This 
          cruise was run by WHOI with 1 SIO Tech aboard to help with LV 
          work. As a result, no "official" hyd file was ever created. I got 
          P,T,S data from SIO, nuts from OSU, C-14 from Stuiver and Ostlund. 
          
            31WTP17C.doc  LV general info file from Talley
            31WTP17C.ps   Talley postscript cruise report for LV work
            31WTP17.lvs   original SIO P,T,S file 
            P16CLV.sta -  my final version of the LV station file
            P16CLV.data - my final version of the LV data file with C14, C13, 
                          nuts, and interpolated oxygen. I provided all final QC 
                          flags.P16CLV.pdf - my final report for this leg. 
                          Appendix includes decklog notes, etc. This document 
                          failed to get an official OTL report number or data (I 
                          use 1/31/97).

          I transferred files over to the ftp-incoming directory the easy way 
          (for me)...  You will find the following "new" directories in 
          /usr/export/ftp-incoming on whpo:
              p16a_p17a
              p17c_p17s_p16s
              p17e_p19s
          I already gave you p19c (which I see is in P19Cdoc).  I thought it 
          was redundant to put long names in every filename, so I made the 
          directory name with the cruise lines, and the files are all the 
          same.  The figs files are all figxx.ps (where xx should indicate 
          the figure numbers referenced in the documentation).  I also 
          included ps and ascii versions of the original documentation and 
          applicable appendices.  (appendix a and b will be missing - they 
          are outdated now and shouldn't be included in anything.)

02/26/01  Jenkins      He/Tr shallow        Data are Public
          It was brought to my attention that the WOCE PaciÞc/Indian He-Tr data 
          was not as yet made public. After submitting it to you last year, I 
          had intended on going through it one more time to ensure there were no 
          problems with it. Unfortunately, I have not had the time to do this. 
          Is it possible, therefore, to release it as public data, and if there 
          are any subsequent minor revisions, to make changes? I suspect there 
          might be a few samples in the set that might have got through our 
          initial quality control.

06/07/02  Jenkins      DELHE3              Data Update 
          I don't believe we reported a station 29 bottle 1 for P17c. We 
          reported data for bottles 2,4,6,7,9,10,12 and 14 for that station. 
          Same issue for station 41. We didn't analyze a bottle 3 there. We only 
          reported data for bottles 2,4<=>16,18 and 19.
          
          By the way, negative values for del3He are certainly valid, and 
          should not be set to zero. Zero values for del3He may not 
          necessarily mean a problem, but I'll go through the numbers you 
          listed.
          
          We took some copper tube samples from station 123 (bottles 2<=>17) 
          on P17c. Although the samples were analyzed on the mass 
          spectrometer, the results were not processed appropriately (they 
          slipped through the net) yet somehow got included in the 
          submission. The best thing to do here is to eliminate them for the 
          atlas, and we'll see if we can recalculate them and resubmit them 
          later.
          
          Sample 121-1-8  (160.8 dbar)  was underextracted (procedural problem) 
                                        and should be eliminated.
          Sample 121-1-5  (110.8 dbar)  should be fine: the del3He = -0.004% 
                                        (thus was rounding to zero for you)
          Sample 116-1-4  (80.1 dbar)   was not analyzed by us (I don't know 
                                        how it got in the mix)
          Sample 110-1-9  (212.2 dbar)  was a failed analysis and should not 
                                        have been reported
          Sample 110-1-11 (310.3 dbar)  was not analyzed by us for helium
          Samples 80-1-X  (82-150 dbar) were not analyzed by us for helium (I 
                                        don't know why, but they weren't)
          Sample 65-1-4   (73 dbar)     wasn't analyzed by us for helium
          Sample 65-1-13  (610 dbar)    wasn't analyzed by us for helium
          Sample 54-1-8   (241 dbar)    was underextracted (procedural problem) 
                                        and should be eliminated
          Sample 48-1-7   (232 dbar)    wasn't analyzed by us for helium
          Sample 44-1-14  (601 dbar)    was underextracted (procedural problem) 
                                        and should be eliminated
          Sample 33-1-11  (300 dbar)    was underextracted (procedural problem) 
                                        and should be eliminated
          Sample 21-1-10  (253 dbar)    wasn't analyzed by us for helium
          Sample17-2-15   (699 dbar)    wasn't analyzed by us for helium
          
          In short, the only one from the bunch that should be kept is 121-
          1-5 (110.8 dbar). I'm sorry that the other rubbish somehow got 
          entrained in the file. I think it was one of my earlier submissions.
