INTRODUCTION

The hydrographic and CTD data presented in this report were collected aboard 
the RV Thomas Washington on the second leg of the Marathon Expedition, from 
Honolulu, Hawaii to Kodiak, Alaska (4 May - 4 June, 1984). The NODC 
identification number for the cruise is TW 261. The objective of the expedition 
was to provide information about the general circulation from the sea surface 
to the bottom in the northeastern Pacific with sufficient resolution along the 
cruise track to resolve the spacing of fronts and the scale of eddy 
variability. Except in boundary regimes at the beginning and end of the cruise 
where all stations extend from top to bottom, stations alternated between full 
water column coverage and coverage to 1500 meters. Station spacing between 28°N 
and 42°N was decreased in order to better sample the active frontal region. 
During the cruise, current meter moorings at 28°N and 42°N were retrieved and 
reset for P. Niiler by a separate group aboard the ship.

The hydrographic and CTD data presented in this report were collected and 
processed by the Physical and Chemical Oceanographic Data Facility (now part of 
the Shipboard Technical Support Group) at Scripps Institution of Oceanography. 
The hydrographic and 2-db CTD data have been sent to the National Oceanographic 
Data Center. Note that there is no station 72 on the cruise.


STANDARD PROCEDURES

Hydrographic (Rosette) Data

Each station consisted of a CTD lowering with a rosette carrying 24 Niskin 
bottles. Most stations included four reversing thermometer racks with one at 
the surface, one at the bottom, and the others at widely spaced intervals. 
Water samples were collected on the upcast and analyzed for salinity, oxygen, 
silicate, phosphate, nitrate, and nitrite. Samples for tritium analysis were 
collected for Dr. R. Fine and were processed by the Tritium Laboratory at the 
University of Miami.

Pressure and temperature for the discrete hydrographic tabulations were taken 
from the calibrated CTD data. The CTD pressure and temperature calibrations are 
discussed in the following section. Occasional discrepancies between the bottom 
depth listed in the header record and the maximum depth of the station resulted 
from incompatibility of the depth as read from the PDR and the actual depth of 
the cast.

Depths were calculated from CTD pressures (Saunders, 1981).

Salinity samples were analyzed at sea using one of two Guildline Autosal 
inductive salinometers. All salinity values are calculated from conductivity 
using the 1978 practical salinity scale (UNESCO, 1981) and are tabulated to 
three decimal places. Standard seawater batch P92 was used to standardize the 
salinometer at the beginning and end of each station; salinities are reported 
relative to P92 and have not been adjusted further. Mantyla (1987) compared 
various batches of standard seawater with batch P96; he found that the salinity 
of P92 is about 0.003 ‰ less than that of P96. A section made in 1985 which 
intersected the Marathon II section and on which P96 was used as a standard 
showed salinities in the deep water which were indeed about 0.003 ‰ higher than 
Marathon II, indicating that the laboratory comparisons hold in situ and that 
the precision of the Autosal measurements is high. Bottle salinities were 
compared with CTD salinities to identify leaking bottles or salinometer 
malfunctions. Calibrated CTD salinities were used to replace bottle salinities 
in the event of problems and are indicated by the letter "D" in the 
hydrographic data tables. All salinities on station 34 were replaced by CTD 
salinities because of extensive drift in the autosalinometer standardization 
from the beginning to the end of that station's analysis; because the CTD 
salinities were calibrated using a large group of adjacent stations, the CTD 
salinities for station 34 are nearly as precise as those from bottle data.

Dissolved oxygen was determined by the Winkler method as modified by Carpenter 
(1965), using the equipment and procedure outlined by Anderson (1971). A small 
number of oxygen values were discarded because contamination by rusty springs 
in the Niskin bottles resulted in low values. The bad springs caused greater 
problems with phosphate measurements. The precision of oxygen measurements is 
.01 mill and accuracy is 2%.

Silicate, phosphate, nitrate and nitrite were analyzed at sea using an 
autoanalyzer. The procedures used are similar to those described in Atlas et 
al. (1971). Artificial seawater was used as a standard for the first 19 
stations; this resulted in high values for all nutrients and was corrected by 
reducing the absorbance slope by 6.25% for these stations. During the early 
part of the cruise, the springs in a large number of Niskin bottles rusted as a 
result of inadequate coating. Most rusty springs were replaced after station 
21. Phosphate measurements were the most strongly affected; hence a large 
number of phosphate measurements have been deleted from stations 1 to 21. Two 
bottles continued to cause problems on subsequent stations; all phosphate 
values from these bottles have been deleted. Oxygen measurements were also 
affected, but apparently less severely; oxygens have been deleted from a 
smaller number of stations. Silicate, nitrate, nitrite, and salinity values 
were apparently unaffected by the rusted springs. Nitrate measurements on 
station 80 have been deleted because of problems with the cadmium column in the 
autoanalyzer. A portion of the silicate values on station 87 were adversely 
affected by a 2°C change in the laboratory temperature and have been deleted.

The precision of nutrient measurements is estimated to be less than .5% and 
accuracy is 2% to 3%.


CONDUCTIVITY/TEMPERATURE/DEPTH (CTD) DATA

A single Neil Brown Mark III CTD was used for all casts. The time series data 
were processed and calibrated by PACODF; the final product is a 2 db pressure 
series.

Pressure, temperature, and conductivity were sampled at 32 frames/second and 
recorded on audio tape. Output from the oxygen probe was updated at 8 
frames/second and recorded with the other three parameters; it was not 
processed. The audio tapes were digitized following the cruise. There was no 
obvious increase in noise due to digitization following the cruise; however, 
gaps in the final data for stations 13 and 42 resulted from yoyo's made to 
compensate for the ends of audio tape reels.

Pressure, temperature and conductivity data were block-averaged in one second 
intervals. Values which were more than four standard deviations from the 
average were eliminated, the average was recalculated, and values more than 2 
standard deviations from the average were discarded.

The CTD pressure transducer was calibrated in a temperature-controlled bath to 
the PACODF Ashcroft deadweight-tester pressure standard. Thermal response-time, 
thermal hysteresis and mechanical hysteresis were measured. The mechanical 
hysteresis loading curves were measured at 0°C and 23°C and at maximum loadings 
of 2225 and 8825 PSI. The transducer thermal response time was derived from the 
pressure response to a thermal step change from 21°C to 0°C. There was no 
significant difference between pre- and post-cruise calibrations. Pressure 
calibrations were applied to the 1-second averages using a family of hysteresis 
curves based on the laboratory calculations. There was no significant drift in 
comparisons between CTD and thermometric pressures, based on reversing 
thermometers mounted on an average of 4 bottles on every cast. The mean 
difference between calibrated CTD pressures and thermometric pressures was 2.5 
db.

The CTD platinum resistance thermometer was calibrated in a temperature-
controlled bath to the PACODF Leeds and Northrup PRT temperature standard at 
0°C, 10°C and 25°C. Calibrations were performed before and after the cruise: 
there was a .002 to .003° decrease in the CTD temperature reading. In addition 
to a constant second-order slope applied to all casts as a result of the PRT 
calibrations, an offset that was linear as a function of time was applied to 
the full cruise to compensate for the shift between pre- and post-cruise 
calibrations. The mean difference between CTD temperatures and thermometer 
values was -0.0005°C.

After pressure and temperature calibration, the up and downcast CTD salinities 
differed by no more than .001 ‰ in the deep water, except on a few stations 
which had obvious offsets in conductivity.

Conductivity was calibrated using bottle salinities collected on the upcasts. 
Bottle sample conductivities were calculated from the sample salinities and 
from CTD pressures and temperatures. A conductivity slope correction was 
calculated as a third order least-squares fit to station number. After 
application of the slope correction, a conductivity offset for each cast was 
calculated and applied. All bottle samples were used for calibration with 
heavier weighting of samples below 1000 db. The mean difference between final 
CTD conductivities and sample conductivies was 0.00073 mhos. Additional offset 
corrections were made following comparisons of calibrated downcast salinities 
with bottle salinities in order to account for discontinuous shifts in the 
conductivity transducer response.

After processing the time series, a roll filter was applied to eliminate 
pressure reversals and a 2 db pressure series was constructed by block-
averaging all 1-second values within each 2 db bin. The final data set contains 
.46% missing data or 727 of 168,549 data points. Most missing data are at 
single levels and result from block-averaging in one second intervals followed 
by pressure sequencing. Eleven of the 98 stations account for 423 missing 
values, or more than half. The only blocks of missing data are 3422-3438 db at 
station 13 and 4438-4484 db at station 42, both due to large yo-yo's occasioned 
by operator compensation for the end of audio tape recordings.

Seven upcasts were sent instead of downcasts because of major offsets or other 
instrument-related problems on the downcasts. The up-casts are stations 29, 50, 
80, 82, 84, 85, and 89.

CCHDO Data Processing Notes

Date      LastName    Data Type    Event           Summary
--------  ----------  -----------  --------------  ---------------------------------------
11/13/03  Sanborn     SUM          Update Needed   Time & lat/long changes
          Stn  7:     hour/min is wrong for EN     Time should be 0405
          Stn 28:     hour/min is wrong for BE     Time should be 1938
          Stn 43:     long. should probably be 159 Longitude should be 151

11/26/03  Sanborn     BTL/SUM      Reformatted     May still need QC
          I did convert it, the bottle data, to WOCE format. I sent Lynne a 
          *.sea and *.sum file. I wanted to do a little fine-tuning on 
          it, not data changes, but more likely quality code consistency. 

01/07/04  Anderson    CTD/BTL/SUM  Data Updated:   Data & formatting corrections
          .sum 
             Corrected time for sta. 7, EN.  Had 4050 changed to 0405.  
               (See Sandborn, 11/13/03).
             Corrected time for sta. 28, BE.  Had 2938 changed to 1938.  
               (See Sandborn, 11/13/03). 
             Corrected longitude for sta. 43.  Had 159 changed to 151.  
               (See Sandborn, 11/13/03).  
             Stations 28, 32, 43, 46, 50, 54, 62, 66, 70, and 82 are stations 
               that start on one day and end the next day after midnight.  All 
               of these stations had the wrong day for EN, I changed them to 
               the correct day.
             Station 36 had the day for BE as 16 and it should have been 15.  
               I changed it to 15.
             Station 45 has a time of 0000 for BE, BO, and EN, I left it that way.
             Station 51 had the day for BE, BO, and EN as 19.  It should have been 
               20, so I changed it to 20. 
             Station 89 had the month as 05 and the day as 31 for EN.  It should 
               have been month 06 and day 01, so I changed it.
             Removed CR's from end of lines. 
             Some adding and deleting of spaces to make file conform to the WHP format.

          .sea 
             Removed the Q1 and Q2 flags for REVPRS and REVTMP and eliminated the 
               *'s under those parameters.

          .ctd 
             The ctd's were all in one file.  Broke the file into individual stations, 
               and added headers.  There were no Q1 flags, so I put 9 for all the -9.0 
               values and 2 for all the other values.     
             In order to get sta. 3 and sta. 6 converted to exchange I had to put a 
               bogus bottom UNC DEPTH in the .sum file.  This was only used for the 
               conversion to exchange.

--------  ----------  -----------  --------------   --------------------------------------
01/13/04  Bartolacci  CTD/BTL      Website Updated: Files online w/ netCDF btl file errors
          Upon conversion to netcdf, the exchange CTD files were opened to find one more 
          .csv CTD file than original woce ctd files. I've been trying to figure out why 
          the exchange conversion generated a file with no station number but have been 
          unsuccessful. It has valid data in it that belongs to station 3 but no header 
          information. However, station 3 also has a normal .csv file generated as well. 
          This problem remains unsolved at this time.

          I've renamed the CTD files to indicate the correct directory name and they 
          converted to netCDF fine (no extra files were generated). Bottle file converted 
          to netCDF, but nitrite values are getting listed as blanks (even though the 
          original and csv files have values). This is also unclear at this time and there 
          are no format checking tools for netCDF at this time.

          All files have been put online, however the errors with the netCDF bottle file 
          are still present.

01/29/04  Bartolacci  Cruise ID    Website Updated: Public. Was pr16_00a, nowp16_1984a
          This cruise has been relabeled from pr16_00a to p16_1984a.  All files have been 
          renamed and/or remade to reflect this change.  This cruise's data has been moved 
          from the repeat data area to the new co2clivar data directories.  All original 
          files and notes regarding reformatting and other issues have been moved also.

          This cruise will not link to the public site until the change to the information 
          has been entered into the database and the new web page has been made public.

03/29/04  Anderson    TRITUM       Data Update      Qual flags set to 2
          Merged the TRITUM and TRITER data I got from Lynne Talley into file 
            p16_1984ahy.txt (Marathon II).  
          There were no QUALT flags, so I set the Q1 and Q2 flags for TRITUM to 2.
          The files for this line still need to be linked.

03/30/04  Anderson    DELHE3       Data Update      Changed Q flags
          Changed Q1 and Q2 flage for DELHE3 at sta. 56, bottle 128 from 2 to 3 
          re email from Lynne Talley (below).

            Date: Mon, 29 Mar 2004 23:41:42 -0800 (PST)
            From: Lynne Talley <lynne@gyre.ucsd.edu>
            To: lynne@gyre.ucsd.edu, sharon@gyre.ucsd.edu, whpo@ucsd.edu
            Subject: p13 delhe3 flag sta 56

            Sarilee - on P13, when the helium value at sta. 56, bottle 128, was flagged 
            as "3", the DELHE3 value should also have been flagged as "3".

06/19/05  Talley  Cruise Report  Submitted          scan of hard copy
          Here are the first 19 pages of the data report from the 1984 occupation of P16. 
          I will send over a copy for Kristin to keep in her files.  The report includes 
          a data listing for each station and a set of profiles for each station, which we 
          have not scanned in.
