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 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. Bottle Data There were five generic types of casts performed with differing sampling protocols. Generally speaking, the samplings associated with these casts were as follows, but there is some cast-to-cast variation. * Hydrographic o Oxygen, o Total CO2, o Total Alkalinity, o Nutrients o Chlorophyll/Phaeophytin o Phytoplankton o Salinity o O18/O16 o Benthic o Dissolved Organic Matter/Particulate Organic Matter o Thorium-234 o C13/N15 * Productivity/Zooplankton o Oxygen o Oxygen Respiration o Productivity o Nutrients o Chlorophyll o HPLC o Bacteria o Micro Zooplankton o Particulate Organic Matter o Dissolved Organic Matter/Lignin o Bio-Optics o Taxonomy o C13/N15 * Bio-Markers o Nutrients o Particulate Organic Matter o Dissolved Organic Matter/Lignin o C13/N15 * Radium o Nutrients o Radium o C13/N15 * Zooplankton o Nutrients o Micro Zooplankton o C13/N15 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 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. References Armstrong, F.

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). Station 001.001 101 Sample Log: "Leak from bottom cap after O2 drawn."
