Data Set Overview

184 CTD casts on 60 stations were attempted. 4 of these were aborted, with no 
CTD data and no water samples.  These casts were Station 022 Cast 01, Station 
022 Cast 03, Station 022 Cast 04, and Station 049 Cast 01.


Instrumentation 

CTD casts were performed with a rosette system consisting of a 12-place rosette 
frame with 30 liter bottles and a 12-place SBE-32 Carousel pylon.  Underwater 
electronic components consisted of:

• Sea-Bird Electronics, Inc. (SBE) 911plus CTD,
• WETLabs C-Star transmissometer with a 25cm path length and 660nm wavelength,
• Biospherical Instruments, Inc. Photosynthetically Active Radiation (PAR) 
  sensor,
• Chelsea MkIII Aquatracka fluorometer, and
• Simrad, 5 volt - 2-500 meter altimeter.

Additionally, a Dr. Haardt fluorometer designed to detect colored organic 
matter (CDOM) and a Secchi disk were mounted on the CTD package. The CTD, 
transmissometer, and the two fluorometers were mounted horizontally along the 
bottom of the rosette frame. The PAR sensor was located at the top of the 
rosette. The surface PAR sensor was located on a newly installed I-beam antenna 
support atop the helicopter shack.  All sensors except the Secchi disk were 
interfaced with the CTD system. This instrument package provided pressure, dual 
temperature and dual conductivity channels as well as light transmissivity and 
fluorometric signals at a sample rate of 24 scans per second. 

The bottles on the rosette were General Oceanic 30 liter bottles. The bottles 
were equipped with internal nylon coated springs and silicone o-rings which are 
used to minimize toxicity to the sample. Bottle numbering is 1 to 12 with 1 
tripped first usually at the deepest sampling level and 12 tripped last at the 
shallowest sampling level. The rosette system was suspended from a standard 
UNOLS 3 conductor 0.322" electromechanical cable.

The CTD used was serial number 09P24152-0638 and the sensor's model and serial 
numbers are listed in Table 1. At Station 022, cast 1, the CTD failed when 
three connectors were found flooded. The CTD was replaced with 09P24152-0639. 
After cast 8 at Station 022, it was also determined that the Haardt fluorometer 
was damaged and it was removed from service. This data from Station 022 has 
been deleted.

The distance of the mid-points of the 30 L Niskin bottles from the bottom-
mounted sensors was ~1.19m. The 30 Liter Niskin bottles are ~1.0 m long. The 
secchi disk was mounted 2.2m above the bottom of the rosette frame.


Problems and/or Procedural changes

At times small areas of the nylon coating on the Niskin bottle springs broke 
down so there may be some minor iron contamination in some samples. HLY0403 
rosette operations were continually beset by problems with bottle leaks caused 
by Niskin bottle end o-rings falling out of position.  Typically, each cast had 
one such occurrence.  Data from leaking bottles were carefully assessed by 
comparing CTD oxygen and salinity data against bottle salinities and 
temperatures and it was found that spigot leaks normally did not compromise 
sample quality. Samples were usually not taken from bottles with severe leaks 
caused by poorly sealed bottom end-caps, and in other cases data from leaking 
bottles were noted as being questionable.  Thus, the main effect of the leaking 
bottles was to increase the sample spacing of good data on some casts. Some 
bottles were more prone than others to o-ring problems, but no clear-cut 
patterns emerged except that there seemed to be more problems on deeper casts 
which would implicate a pressure effect or prolonged exposure to low 
temperatures.  Since both the bottles and o-rings were purchased just before the 
two 2004 Healy cruises, we suspect a manufacturing defect or change in either 
the bottles or o-rings. Some of the problems were gross, i.e. the o-ring would 
be visible out the side of the end cap, but others were more subtle. Every time 
an o-ring problem was suspected, the o-ring was carefully inspected, and 
replaced if necessary.  Also, at several points during the cruise all o-rings 
were inspected.  During the spring expedition, HLY-04-02, the contents of 
various packages of spare o-rings were measured to locate 'large' or 'small' o-
rings (within the manufacturer's tolerance), and a remedial 'large' set was 
installed.  Another time Coast Guard personnel replaced all the o-rings from 
their own supply.  Yet all these remedial attempts were to no particular avail. 
A different batch of o-rings were procured prior to this cruise (HLY-04-03) but 
they  made minimal difference vis a vis  bottle leaks. 



CTD Data

CTD Laboratory Calibration Procedures

Pre-cruise laboratory calibrations of CTD pressure, temperature and conductivity 
sensors were used to generate coefficients for the calculation of these 
parameters from their respective sensor frequencies. The temperature, 
conductivity and oxygen sensors were recalibrated prior to the HLY-04-3 
expedition. The temperature, conductivity and oxygen calibrations were performed 
at Sea-Bird Electronics, Inc. in Bellevue, Washington.  Calibration of the 
pressure sensor was performed prior to the HLY0402 spring cruise by Scripps 
Institution of Oceanography, Shipboard Technical Support/Oceanographic Data 
Facility (SIO/STS/ODF) personnel. The Sea-Bird laboratory temperature 
calibrations were referenced to the International Temperature Scale of 1990 
(ITS-90). 


CTD Data Acquisition

The CTD 911plus was operated generally as suggested in the Sea-Bird CTD 
Operating and Repair Manual, which contains a description of the system, its 
operation and functions (Sea-Bird Electronics, Inc., 2002). One difference from 
Sea-Bird's operation is that data acquisition was started on deck. This 
procedure allows a check of the pressure offset and an unblocked reading of the 
transmissometer. The Seasoft acquisition program as described in the CTD Data 
Acquisition Software Manual (Sea-Bird Electronics, Inc., 2001) provided a real-
time graphical display of selected parameters adequate to monitor CTD 
performance and information for the selection of bottle-tripping depths. Raw 
data from the CTD were archived on the PC's hard disk at the full 24 Hz sampling 
rate. 

A CTD Station Sheet form was filled in for each deployment, providing a record 
of times, positions, bottom depth, bottle sampling depths, and every attempt to 
trip a bottle, as well as any pertinent comments. When the equipment and 
personnel were ready, data acquisition was started.  The CTD operator pressed a 
control key (flag), which appends a summary line into the files created for 
"inventory" files.  This file contains a summary of the time, ship's position, 
and current scan number each time the control key is pressed.  They are used as 
a reference to mark important events during the cast, such as on deck pressure, 
when the lowering was initiated, when the package was at the bottom, when 
bottles were tripped and the on-deck pressure with ending position.  After the 
initial flag, the rosette/CTD system was lowered into the water and held at 5 
meters wire out for 3-5 minutes to permit activation of the CTD pumps and 
equilibration of the sensors.  Then, the operator had the CTD raised to the 
surface, again created a flag, and simultaneously directed the winch operator to 
begin lowering.  The operator created a flag at the deepest point of the cast. 
Bottom depths were calculated by combining the distance above bottom, reported 
by the altimeter, and the maximum depth of the CTD package when bottom altimeter 
readings were available.  If there was no altimeter reading, then the bottom 
depth is reported from the ship's Bathy 2000 or Knudsen model 320B/R depth 
recorder.  These data, corrected for the draft of the transducer, were logged in 
uncorrected meters (assuming a sound velocity of 1500 m/sec). If the altimeter 
and depth recorder data were unavailable, the final resort was to use depth data 
from the SeaBeam system (corrected sound velocities).

The wire out corresponding to each bottle trip was written on the station log 
and the trips were electronically flagged in the data file.  The performance of 
all sensors was monitored during the cast.  After the rosette recovery, the 
operator created a final flag denoting the end of the cast. Any faulty equipment 
or exceptionally noisy data were noted on the log sheet. 


CTD Data Processing

Pressure

CTD values determined on deck before and after each cast were compared to 
determine a pressure offset correction. The comparison suggested that no 
pressure offset was necessary.


Temperature

The temperature sensors were calibrated in July 2004.  The dual temperature 
sensors were monitored during the expedition and exhibited good agreement.  It 
appears that no additional corrections need to be applied. A post-cruise 
calibration will be performed.

Conductivity

The conductivity sensors were calibrated in July 2004. Corrected CTD pressure 
and temperature values were used with bottle salinities to back-calculate bottle 
conductivities. Comparison of these bottle values with the CTD primary 
conductivity values indicated no additional offset needed to be applied to the 
data.

Transmissometer

A WETLabs calibrated transmissometer was utilized throughout the cruise.  An on 
deck calibration check was performed and even though there was little 
degradation from the last calibration, the new coefficients were applied to the 
data set.

Oxygen, Fluorometer, and PAR

The CTD oxygen data are only intended for qualitative use.  The oxygen sensor 
was calibrated in July 2004. Similarly, the fluorometric and PAR data are not 
calibrated.

Data Processing

Sea-Bird Seasoft CTD processing software was employed. The processing programs 
are outlined below.  A more complete description may be found in the Sea-Bird 
Software Manual which is available from the Sea-Bird website (www.seabird.com).

The sequence of programs that were run in processing CTD data from this cruise 
are as follows:

* DATCNV - Converts data from raw frequencies and voltages to corrected 
  engineering units
* WILDEDIT - Eliminates large spikes
* CELLTM - Applies conductivity cell thermal mass correction
* FILTER - A low pass filter to smooth pressure for LOOPEDIT
* LOOPEDIT - Marks scans where velocity is less than selected value to avoid 
  pressure reversals from ship roll, or during bottle flushing.
* DERIVE - Computes calculated parameters
* BINAVG - Average data into desired pressure bins

The quality control steps included:

* Sensor verification After the CTD was set up and sensor serial numbers and 
  sensor location entered into the computer, another check was made to verify 
  that there were no tabulation errors.
* Seasoft Configuration File was reviewed to verify that individual sensors were 
  represented correctly, with the correct coefficients.
* Temperature was verified by comparing primary and secondary sensor data.
* Conductivity was checked by comparison of the two sensors with each other and 
  with bottle salinity samples. 
* Position Check A chart of the ship's track was produced and reviewed for any 
  serious problems.  The positions were acquired from the ship's GPS (P-code) 
  navigation system. 
* Visual Check Plots of each usable cast were produced and reviewed for any 
  noise and spikes that may have been missed by the processing programs.
* The density profile was checked for inversions that might have been produced 
  by sensor noise or response mismatches.


CTD Data Footnoting

WHP water bottle quality flags were assigned as defined in the WOCE Operations 
Manual (Joyce and Corry, 1994). These flags and interpretation are tabulated in 
the CTD and Bottle Data Distribution, Quality Flags section of this document.

Data Comments 

Fine structure including minor density inversions that may appear in the upper ~ 
10 m of the profiles is most likely caused by ship discharges/turbulence. To 
minimize the ship effect, engine cooling water discharges were restricted to the 
port side of the Healy.  A "yo yo" procedure was adopted to induce bottle 
flushing whenever waves and ship motion were weak.  This procedure was employed 
for all bottle trips under quiescent conditions except for productivity casts, 
and for surface and bottom bottles that were usually kept at depth for ~2 
minutes before tripping whereas the yo yo procedure generally involved a ~30 
second wait, a yo yo and another ~30 second wait. Regardless of the procedure 
employed, the CTD operators were instructed to wait for at least 1 minute 
(typically > 1.5 minutes) before tripping the bottle.

All salinity, nutrient and dissolved oxygen data collected by the "service" team 
have gone through several stages of editing and are not likely to change 
significantly.  The chlorophyll observations reported here may may undergo 
further editing.  Please note that changes in the refractive index of samples 
with salinity, baseline issues, temperature effects, etc. can cause variability 
in the ammonium and urea methods that is not reflective of changes in ambient 
concentrations. Differences of < ~ 0.15 µM should be treated with caution. 
Please contact L. A. Codispoti, if you wish to interpret small differences in 
ammonium and urea data (Codispoti@hpl.umces.edu) The other nutrient data meet 
WOCE/JGOFS standards.

The correspondence between individual sample containers and the rosette bottle 
from which the sample was drawn was recorded on the sample log for the cast. 
This log also included any comments or anomalous conditions noted concerning  
the rosette and bottles. 

Normal sampling practice included opening the drain valve before the air vent on 
the bottle, to check for air leaks. This observation and other diagnostic 
comments (e.g., "lanyard caught in lid", "valve left open") that might later 
prove useful in determining sample integrity were routinely noted on the sample 
log.  

Bottle Data Processing

After the samples were drawn and analyzed, the next stage of processing involved 
merging the different data streams into a common file. The rosette cast and 
bottle numbers were the primary identification for all ODF-analyzed samples 
taken from the bottle, and were used to merge the analytical results with the 
CTD data associated with that bottle.

Diagnostic comments from the sample log, and notes from analysts and/or bottle 
data processors were entered into a computer file associated with each station 
(the "quality" file) as part of the quality control procedure. Sample data from 
bottles suspected of leaking were checked to see if the properties were 
consistent with the profile for the cast, with adjacent stations, and, where 
applicable, with the CTD data. Direct inspection of the tabular data, property-
property plots and vertical sections were all employed to check the data. 
Revisions were made whenever there was an objective reason to delete, annotate 
or re-calculate a datum. WHP water sample codes were selected to indicate the 
reliability of the individual parameters affected by the comments. WHP bottle 
codes were assigned where evidence showed the entire bottle was affected, as in 
the case of a leak, or a bottle trip at other than the intended depth.

Specific data processing and techniques and additional quality control are 
included with the parameter write-up.

Pressure and Temperatures

All pressures and temperatures for the bottle data tabulation were obtained by 
averaging CTD data for a brief interval at the time the bottle was closed and 
then applying the appropriate calibration data. 

The temperatures are reported using the International Temperature Scale of 1990.



Salinity

337 salinity samples were analyzed in 13 analyses runs.

Sampling and Data Processing 

Salinity samples were drawn into 200 ml high alumina borosilicate bottles, which 
were rinsed three times with sample prior to filling. The bottles were sealed 
with custom-made plastic insert thimbles and Nalgene screw caps. This container 
provides very low container dissolution and sample evaporation.  

Equipment and Techniques 

A Guildline Autosal 8400B #65-715, standardized with IAPSO Standard Seawater 
(SSW) batch P-144, was used to measure the salinities. Prior to the analyses, 
the samples were stored to permit equilibration to laboratory temperature, 
usually 8-20 hours.  The salinometer was outfitted with an Ocean Scientific 
International interface for computer-aided measurement. The salinometer was 
standardized with a fresh vial of standard seawater (SSW) at the beginning of 
each analysis run.  Instrument drift was determined by running a SSW vial after 
the last sample was run through the autosal. The salinometer cell was flushed 
until two successive readings met software criteria for consistency; these were 
then averaged for a final result. The estimated accuracy of bottle salinities 
run at sea is usually better than 0.002 PSU relative to the particular standard 
seawater batch used.

Laboratory Temperature

The temperature stability in the salinometer laboratory was moderate; variation 
was no more than 3ºC during a run of samples.  The laboratory temperature was 
generally 2-3ºC lower than the Autosal bath temperature.



Oxygen

974 samples were analyzed for oxygen.

Sampling and Data Processing

Samples were collected for dissolved oxygen analyses as the first sample after 
the rosette was brought on board. Using a Tygon drawing tube, nominal 125ml 
volume-calibrated iodine flasks were rinsed then filled and allowed to overflow 
for approximately 3 flask volumes. The sample draw temperature was measured with 
a small platinum resistance thermometer embedded in the drawing tube. Reagents 
were added to fix the oxygen before stoppering. The flasks were shaken twice to 
assure thorough dispersion of the precipitate, once immediately after drawing, 
and then again after about 20 minutes.  The samples were usually analyzed within 
several hours of collection. 

Thiosulfate normalities were calculated from each standardization and corrected 
to 20ºC. Periodically, the 20ºC normalities and the blanks were plotted versus 
time and were reviewed for possible problems. New thiosulfate normalities were 
recalculated as a linear function of time, if warranted. The oxygen data were 
recalculated using the smoothed normality and an averaged reagent blank. Oxygens 
were converted from milliliters per liter to micromoles per kilogram using the 
sampling draw temperature and the sample's salinity. 



Equipment and Techniques

Dissolved oxygen analyses were performed with an ODF-designed automated oxygen 
titrator using photometric end-point detection based on the absorption of 365nm 
wavelength ultra-violet light. The titration of the samples and the data logging 
were controlled by PC software. Thiosulfate was dispensed by a Dosimat 665 buret 
driver fitted with a 1.0 ml buret. The ODF method used a whole-bottle modified-
Winkler titration following the technique of Carpenter (1965) with modifications 
by Culberson (1991), but with higher concentrations of potassium iodate standard 
(approximately 0.012N) and thiosulfate solution (55 g/l). Standard KIO3 
solutions prepared ashore were run at the beginning of each run. Reagent and 
distilled water blanks were determined, to account for presence of oxidizing or 
reducing materials.


Volumetric Calibration

Oxygen flask volumes were determined gravimetrically with degassed deionized 
water to determine flask volumes at ODF's chemistry laboratory. This was done 
once before using flasks for the first time and periodically thereafter when a 
suspect bottle volume was detected. The volumetric flasks used in preparing 
standards were volume-calibrated by the same method, as was the 10 ml Dosimat 
buret used to dispense standard iodate solution.


Standards

Potassium iodate was obtained from Johnson Matthey Chemical Co. and was reported 
by the supplier to be >99.4% pure.

Nutrients

1567 samples were analyzed for nutrients in 70 analyses runs. 68 of these 
samples were checks of the system and 177 were for 5 of the ancillary shipboard 
programs.

Sampling and Data Processing

Nutrient samples were drawn into 45 ml polypropylene, screw-capped "oak-ridge 
type" centrifuge tubes. The tubes were rinsed with 10% HCl and then with sample 
three times before filling. Standardizations were performed at the beginning and 
end of each group of analyses (4-38 samples) with an intermediate concentration 
mixed nutrient standard, which was prepared prior to each run from a secondary 
standard in a low-nutrient seawater matrix. The secondary standards were 
prepared aboard ship by dilution from primary standard solutions.  Dry standards 
were pre-weighed at the laboratory at ODF, and transported to the vessel for 
dilution to the primary standard. Sets of 7 different standard concentrations 
covering the range of sample concentrations were analyzed periodically to 
determine the deviation from linearity, if any, as a function of absorbance for 
each nutrient analysis.  A correction for non-linearity was applied to the final 
nutrient concentrations when necessary. 

After each group of samples was analyzed, the raw data file was processed to 
produce another file of response factors, baseline values, and absorbances.  
Suspect values were checked for accuracy against values taken from strip chart 
recordings. Sargasso Sea Water and deep seawater were run occasionally to check 
ammonium and urea baselines and assess system performance in all six nutrient 
channels. 

Nutrients, when reported in micromoles per kilogram, were converted from 
micromoles per liter by dividing by sample density calculated at 1 atm pressure 
(0 db), in situ salinity, and the sample temperature measured at the time of 
analysis.

Also reported is N**, a parameter calculated from nitrate, nitrite, ammonium and 
phosphate concentrations.  This parameter is defined as N** = ((N-16P + 2.98)µM) 
0.87, where P = the phosphate concentration in µM, and N = 
(nitrate+nitrite+ammonium in µM).  This parameter is quite similar to the 
original N* parameter defined by Gruber and Sarmiento (1997) except that we 
include ammonium concentrations because of the high ammonium concentrations that 
can occur in the SBI region.  The underlying premise of both N* and N** is that 
the N/P atomic regeneration ratio in seawater is normally close to the 16/1 N/P 
Redfield ratio.  The assumption is that deviations from this ratio in N/P ratios 
in a water mass arise primarily from nitrogen fixation which produces organic 
matter with N/P ratios in excess of 16/1, or denitrification which consumes 
nitrate and other forms of fixed nitrogen and converts these forms into 
elemental dinitrogen gas.  Values less than 2.98 suggest that a water mass has 
experienced net denitrification and higher values suggest net nitrogen fixation.  
The factors 2.98 and 0.87 are explained by Gruber and Sarmiento (1997), and 
there is some debate about whether they should be included, but we do so in 
order to facilitate comparison with the distributions presented by Gruber and 
Sarmiento (1997).


Equipment and Techniques

Nutrient analyses (nitrate+nitrite, nitrite, phosphate, silicate, ammonium, and 
urea) were performed on an ODF-modified 6-channel Technicon AutoAnalyzer II, 
generally within a few hours after sample collection.  The samples were kept in 
the dark by covering with tin foil or refrigerated at 4(C, if necessary, but 
brought to within 5(C of lab temperature before analysis.  The analog outputs 
from each of the six channels were digitized and logged automatically by 
computer (PC) at 2-second intervals. 

A modification of the Armstrong et al. (Armstrong 1967) procedure was used for 
the analysis of nitrate and nitrite. For the nitrate plus nitrite analysis, the 
seawater sample was passed through a cadmium reduction column where nitrate was 
quantitatively reduced to nitrite. The stream was then passed through a 15mm 
flowcell and the absorbance measured at 540nm.  The same technique was employed 
for nitrite analysis, except the cadmium column was bypassed, and a 50mm 
flowcell was used for measurement.  Periodic checks of the column efficiency 
were made by running alternate equal concentrations of NO2 and NO3 through the 
NO3 channel to ensure that column efficiencies were high (> 95%). Nitrite 
concentrations were subtracted from the nitrate+nitrite values to obtain nitrate 
concentrations.

Phosphate was analyzed using a modification of the Bernhardt and Wilhelms 
[Bernhardt 1967.] technique. The reaction product was heated to ~55ºC to enhance 
color development, then passed through a 50mm flowcell and the absorbance 
measured at 820m.

Silicate was analyzed using the technique of Armstrong et al., (Armstrong, 
1967). The sample was passed through a 15mm flowcell and the absorbance measured 
at 660nm.

Ammonium was determined by the Berthelot reaction (Patton and Crouch 1977) in 
which sodium hypochlorite and phenol react with ammonium ion to produce 
indophenol blue, a blue compound.   The solution was heated to 55°C and passed 
through a 50mm flowcell at 640nm.

Urea was analyzed via a modification of the method of Rahmatullah and Boyde 
(1980), which is based on the classic diacetyl monoxime method.  A solution of 
diacetyl monoxime, thiosemicarbizide and acetone is followed by the addition of 
ferric chloride, which acts as a catalyst.  The resultant solution was heated to 
90°C and passed through a 50mm flowcell. The absorbance was measured at 520nm.

Nutrient Standards

Na2SiF6, the silicate primary standard, was obtained from Johnson Matthey 
Company and Fisher Scientific and was reported by the suppliers to be >98% pure. 
Primary standards for nitrate (KNO3), nitrite (NaNO2), and phosphate (KH2PO4) 
were obtained from Johnson Matthey Chemical Company, and the supplier reported 
purities of 99.999%, 97%, and 99.999%, respectively. Ammonia, (NH4(SO4)2), and 
Urea primary standards were obtained from Fisher Scientific and reported to be 
>99% pure. 

Bottle Data Footnoting

WHP water bottle quality flags were assigned as defined in the WOCE Operations 
Manual [Joyce]. These flags and interpretation are tabulated in the Data 
Distribution, Bottle Data, Quality Flags section of this document.

Data Distribution 

The CTD and bottle data can be obtained through NCAR's Earth Observing 
Laboratory website, www.eol.ucar.edu/projects/sbi. The data are reported using 
the WHP-Exchange (WOCE Hydrographic Program) format and the quality coding 
follows those outlined by the WOCE program (Joyce, 1994). In addition, the 
format can be obtained through the WOCE Hydrographic Program website, 
WHPO.ucsd.edu. The descriptions in this document have been edited from the 
reference to annotate the format specific to this data distribution. ASCII files 
for each station were created with comments recorded on the CTD Station Logs 
during data acquisition. These ASCII files include data processing comments 
noting any problems, their resolution, and footnoting that may have occurred.  A 
separate ASCII file was also created with the comments from the Sample Log 
Sheets that include problems with the Niskin bottles that could compromise the 
samples. Comments arising from inspection and checking of the data are also 
included in the ASCII file. These comment files are also in the EOL/JOSS 
database.  Raw (unprocessed) CTD data files are archived in the EOL/JOSS 
database.  The file hly0403_ctd_raw.zip contains ssscc.cfg, ssscc.con, ssscc.dat 
and ssscc.hdr (where sss = station number and cc = cast number) files as 
acquired by the SeaBird SeaSave acquisition program, sbscan.sum file and 
calibration information for all sensors.  The *.cfg file is datcnv.cfg with the 
beginning scan number and *.con files may include a correction based on the 
bottle salinity samples.  The sbscan.sum file is a list of stations and 
beginning scan number.  Configuration files for the various SeaBird CTD 
processing programs are also included where applicable.  


General rules for WHP-exchange:

1. Each line must end with a carriage return or end-of-line.

2. With the exception of the file type line, lines starting with a "#" 
   character, or including and following a line which reads "END_DATA", each 
   line in the file must have exactly the same number of commas as do all other 
   lines in that file.

3. The name of a quality flag always begins with the name of the parameter with 
   which it is associated, followed by an underscore character, followed by 
   "FLAG", followed by an underscore, and then followed by an alphanumeric 
   character, W. 

4. The "missing value" for a data value is always defined as -999, but written 
   in the decimal place format of the parameter in question. For example, a 
   missing salinity would be written -999.0000 or a missing phosphate -999.00.
5. The first four characters of the EXPOCODE are the U.S. National Oceanographic 
   Data Center (NODC) country-ship code, then followed by up to an 8 characters 
   expedition name of cruise number, i.e. 32H1HLY0403.

Quality Flags

CTD data quality flags were assigned to the CTDTMP (CTD temperature), CTDSAL 
(CTD salinity) and XMISS (Transmissivity) parameters as follows:

2 Acceptable measurement.
3 Questionable measurement. The data did not fit the station profile or adjacent 
  station comparisons (or possibly bottle data comparisons). The data could be 
  acceptable, but are open to interpretation.
4 Bad measurement. The CTD data were determined to be unusable.
5 Not reported. The CTD data could not be reported, typically when CTD salinity 
  is flagged 3 or 4.
9 Not sampled. No operational sensor was present on this cast

WHP CTD data quality flags were assigned to the CTDOXY (CTD O2), FLUORO 
(Fluorometer), PAR (PAR), SPAR (Surface PAR), and HAARDT (Haardt Fluorometer CDOM) 
parameter as follows:

1 Not calibrated. Data are uncalibrated.
9 Not sampled. No operational sensor was present on this cast. Either the sensor 
  cover was left on or the depth rating necessitated removal.

Quality Flags

CTD data quality flags were assigned to CTDPRS (CTD pressure), CTDTMP (CTD 
temperature), CTDCOND (CTD Conductivity), and CTDSAL (CTD salinity) as defined 
in Data Distribution, CTD Data, Quality Flags section of this document. CTDOXY 
(CTD O2), FLUORO (Fluorometer), PAR (PAR), and SPAR (Surface PAR) parameters are 
flagged with either a 2, acceptable or 9, not drawn.

Bottle quality flags were assigned to the BTLNBR (bottle number) as defined in 
the WOCE Operations Manual [Joyce] with the following additional 
interpretations:

  2  No problems noted.
  3  Leaking.  An air leak large enough to produce an observable effect on a 
     sample is identified by a flag of 3 on the bottle and a flag of 4 on the 
     oxygen.  (Small air leaks may have no observable effect, or may only affect 
     gas samples.)
  4  Did not trip correctly.  Bottles tripped at other than the intended depth 
     were assigned a flag of 4.  There may be no problems with the associated 
     water sample data.
  9  The samples were not drawn from this bottle.  

WHP water sample quality flags were assigned to the water samples using the 
following criteria:

  1  The sample for this measurement was drawn from the water bottle, but the 
     results of the analysis were not (yet) received.
  2  Acceptable measurement.
  3  Questionable measurement. The data did not fit the station profile or 
     adjacent station comparisons (or possibly CTD data comparisons). No notes 
     from the analyst indicated a problem. The data could be acceptable, but are 
     open to interpretation.
  4  Bad measurement. The data did not fit the station profile, adjacent 
     stations or CTD data. There were analytical notes indicating a problem, but 
     data values were reported. Sampling and analytical errors were also flagged 
     as 4.
  5  Not reported. The sample was lost, contaminated or rendered unusable.
  9  The sample for this measurement was not drawn.

Not all of the quality flags are necessarily used on this data set.

APPENDIX A: Bottle Quality Comments

Remarks for deleted samples, missing samples, PI data comments, and WOCE codes 
other than 2 from HLY0403 USCGC Healy. Comments from the Sample Logs and the 
results of ODF's investigations are included in this report. Investigation of 
data may include comparison of bottle salinity and oxygen data with CTD data, 
review of data plots of the station profile and adjoining stations, and 
rereading of charts (i.e. nutrients). Units stated in these comments are degrees 
Celsius for temperature, Practical Salinity Units for salinity, and unless 
otherwise noted, milliliters per liter for oxygen and micromoles per liter for 
Silicate, Nitrate, Nitrite, Phosphate and Urea and Ammounium, if appropriate. 
The first number before the comment is the cast number (CASTNO) times 100 plus 
the bottle number (BTLNBR).
