Carbon Dioxide Information Analysis Center, Oak Ridge National Laboratory, U.S. Department of Energy, Oak Ridge, Tennessee. This data documentation discusses the procedures and methods used to measure total carbon dioxide (TCO2) and total alkalinity (TALK) at hydrographic stations during the R/V John V. Vickers oceanographic cruise in the Pacific Ocean (Section P13). Conducted as part of the World Ocean Circulation Experiment (WOCE) and the National Oceanic and Atmospheric Administration's Climate and Global Change Program, the cruise began in Los Angeles, California, on August 4, 1992, with a transit line (Leg 0) to Dutch Harbor, Alaska. On August 16, the ship departed Dutch Harbor on Leg 1 of WOCE section P13. On September 15, 1992, the R/V John V. Vickers arrived in Kwajalein, Marshall Islands, for emergency repairs, and after 11 days in port departed for Leg 2 of Section P13 on September 26, 1992. The cruise ended on October 21 in Noumea, New Caledonia. Measurements made along WOCE Section P13 included pressure, temperature, salinity [measured by a conductivity, temperature, and depth sensor (CTD)], bottle salinity, bottle oxygen, phosphate, nitrate, nitrite, silicate, chlorofluorocarbons (CFC-11, CFC-12, CFC-113), TCO2, and TALK. The TCO2 was measured by coulometry using a Single-Operator Multiparameter Metabolic Analyzer (SOMMA). The overall precision and accuracy of the analyses was ±2 µmol/kg. Samples collected for TALK were measured by potentiometric titration; precision was ±2 µmol/kg. The CO2-related measurements aboard the R/V John V. Vickers were supported by the U.S. Department of Energy. The WOCE Section P13 data set is available free of charge as a numeric data package (NDP) from the Carbon Dioxide Information Analysis Center. The NDP consists of two oceanographic data files, two FORTRAN 90 data-retrieval routine files, a documentation file, and this printed report, which describes the contents and format of all files as well as the procedures and methods used to obtain the data. Instructions on how to access the data are provided.

BACKGROUND INFORMATION The World Ocean plays a dynamic role in the Earth's climate: It captures heat from the sun, transports it, and releases it thousands of miles away. These oceanic-solar-atmospheric interactions affect winds, rainfall patterns, and temperatures on a global scale. The oceans also play a major role in global carbon-cycle processes. Carbon is unevenly distributed in the oceans because of complex circulation patterns and biogeochemical cycles. The oceans are estimated to hold 38,000 gigatons of carbon, 50 times more than that in the atmosphere and 20 times more than that in plants, animals, and soil. If only 2% of the carbon stored in the oceans were released, the level of atmospheric carbon dioxide (CO2) would double. Every year, the amount of CO2 exchanged across the sea surface is more than 15 times that produced by the burning of fossil fuels, deforestation, and other human activities (Williams 1990). To better understand the ocean's role in climate and climatic changes, several large experiments have been conducted, and others are under way. The largest oceanographic experiment ever attempted is the World Ocean Circulation Experiment (WOCE). A major component of the World Climate Research Program, WOCE brings together the expertise of scientists and technicians from more than 30 nations. In the United States, WOCE is supported by the federal government under the Global Change Research Program. The multiagency U.S. effort is led by the National Science Foundation and is supported by major contributions from the National Oceanic and Atmospheric Administration (NOAA), the U.S. Department of Energy (DOE), the Office of Naval Research, and the National Aeronautics and Space Administration. Although total carbon dioxide (TCO2) is not an official WOCE measurement, a coordinated effort, supported in the United States by DOE, was made on WOCE cruises to measure the global distributions of TCO2 and other carbon-related parameters [total alkalinity (TALK), partial pressure of CO2 (pCO2), and pH]. The goal of the DOE's CO2 survey includes estimation of the meridional transport of inorganic carbon in a manner analogous to the oceanic heat transport (Bryden and Hall 1980; Brewer et al. 1989; Roemmich and Wunsch 1985), evaluation of the exchange of CO2 between the atmosphere and the ocean, and preparation of a database suitable for carbon-cycle modeling and subsequent assessment of anthropogenic CO2 in the oceans. The final data set is expected to cover ~23,000 stations. This report presents CO2-related measurements obtained during the Research Vessel (R/V) John V. Vickers NOAA Climate and Global Change (CGC92) expedition along the WOCE meridional Section P13. 2. DESCRIPTION OF THE EXPEDITION 2.1 R/V John V. Vickers Cruise Information R/V John V.

Vickers. This vessel was operated by the University of Southern California together with officers from the NOAA corps. The goal of the cruise was to carry out a WOCE one-time hydrographic measurement along section P13 which runs along longitude 165° E from the Kamchatka peninsula to New Caledonia. The cruise was split into three legs for logistical regions. 2.2.1 Leg 0: Expedition Code 3220CGC92/0 Leg 0 of the CGC92 expedition consisted of a transit from Los Angeles, California, to Dutch Harbor, Alaska, with 4 stations occupied along the cruise track to test the CTD/rosette system (stations 1 - 4 are not included in the data set). One of these stations was a re-occupation of Station "P" (50° N, 145° W). Scientists from SIO tested an underway ADCP system along the cruise track. 2.2.2 Leg 1: Expedition Code 3220CGC92/1 The chief scientist for Leg 1 of the cruise was Dr. John Bullister of NOAA/PMEL. The R/V John V. Vickers left Dutch Harbor on August 16, 1992, to carry out the sampling along the cruise track, and arrived at Kwajalein, Marshall Islands, on September 15, 1992. Leg 1 consisted of 51 stations (Nos. 5 - 55). The first station on this leg (No. 5) was a CTD/rosette cast test (not included in the data set) made in the Bering Sea, along the transit from Dutch Harbor to the start of the P13 line near the Kamchatka Peninsula. Sampling of the P13 section began with occupation of station No. 6 on August 21, 1992, near the 200-meter isobath off Kamchatka. A series of stations were occupied on a southeastward transit down the continental slope and across the Kamchatka trench. The section turned directly southward at about 51° 30' N and 165° 00' E and continued along the 165° E meridian for the remainder of Leg 1. Nominal station spacing was 30 nautical miles (nm) from the start of the section to about 40° N. Because of a series of delays during the first part of Leg 1, a decision was made to stretch nominal station spacing for the remainder of Leg 1 to 40 nm. Because of concerns about possible structural deformation to the ship and concern over the failure of a watertight door to close properly, work on the P13 CTD/rosette section was halted on September 9, 1992, at about 30° N, and R/V John V. Vickers was ordered to steam directly to Kwajalein. 2.2.3 Leg 2: Expedition Code 3220CGC92/2 The chief scientist for the second leg of the cruise was Dr. Bruce Taft from NOAA/PMEL. The R/V John V. Vickers remained at the dock in Kwajalein for an extended period of time for evaluation of structural integrity by two marine architects and for repair. The ship left Kwajalein on September 26, 1992, and began steaming back to the break-off point to continue work on the P13 section. Despite the delay caused by these repairs, the R/V John V. Vickers had to arrive in Noumea, New Caledonia in time for its subsequent use by Tropical Ocean Global Atmosphere/Coupled Ocean-Atmosphere Response Experiment (TOGA/COARE) investigators. This schedule did not allow enough time to complete the WOCE Section P13 to even minimum WOCE Hydrographic Program (WHPO) spesifications. With the remaining time, R/V John V. Vickers occupied CTD/rosette stations at a nominal spacing of about 60 nm from 28° N to 4° N, and closer spacing from 4° N to 4° 30' S. Lowered ADCP measurements were made on stations between 4° N and 4° S. The section was terminated on October 17, 1992, at 4° 45' S and 164° 00' E in order to arrive in Noumea by the October 21 deadline. A total of 32 stations (Nos. 56 - 88) were occupied during Leg 2 (station No. 60 was aborted and not included in the listings). Throughout the cruise along WOCE Section P13, samples for shipboard analysis of TCO2 and TALK were collected from 10-L Niskin bottles on the 36-position small-volume rosette water sampling system. Of the total of 88 stations on the three legs, CO2 samples were collected from all Niskin bottles throughout the water column on 39 stations. On an additional 41 stations CO2 samples were collected from surface bottles only. 3. DESCRIPTION OF VARIABLES AND METHODS 3.1 Hydrographic Measurements A NOAA/PMEL-designed, 36-position, 10-L rosette frame was used at 84 of the 88 stations during the expedition. A smaller 12-position, 2.4-L rosette was used as a bad-weather backup system at several stations during the cruise. A General Oceanics (GO) 36 "Intelligent" underwater array (pylon) and deck unit was used with the PMEL 36-position system, along with a Neil Brown Instrument Systems (NBIS) MARK III CTD (serial # 1111). The CTD pressure, temperature, and conductivity data were processed and corrected according to laboratory calibrations. Pressure values are expected to be accurate to ±3 dbar, temperature values to ±0.002 C. The salinity analysis aboard R/V John Vickers was determined exclusively with a Guildline 8400 Autosal. This instrument was located in a temperature-controlled room at 20.5 ± 1°C. The bath of the autosal was kept at 21°C and proved to be very stable throughout the cruise. Standardization of the autosal was carried out with International Association for the Physical Sciences of the Ocean (IAPSO) Standard Seawater batch P114. Samples of dissolved oxygen were collected soon after the rosette sampler was brought on board and after CFC and helium samples were collected. Calibrated 125-mL nominal volume iodine determination flasks (Corning 5400-125) were used for sampling. Titration was performed by Carpenter's (1965) whole bottle technique with a modification of the system described by Friederich et al. (1991). All analyses for nutrients were done with an Alpkem RFA/2 320 autoanalyzer. The methods used were modified from those recommended by the Alpkem Corporation. The working nutrient standards used were a mixture of phosphate, silica, nitrate, and nitrite in a low-nutrient natural seawater matrix. Simultaneous analyses were run on the RFA/2 for all of these nutrients. For more detailed information on hydrographic measurements, please see the Chief Scientist report at http://whpo.ucsd.edu/data/onetime/pacific/p13/p13/index.htm . 3.2 Total Carbon Dioxide Measurements The samples for TCO2 were taken in 500-mL borosilicate glass bottles in accordance with the procedure specified in Handbook of Methods for the Analysis of the Various Parameters of the Carbon Dioxide System in Sea Water (DOE 1994), an earlier version of which was available at the time in manuscript version to the DOE Science Team. The samples were poisoned with mercuric chloride to minimize biological activity prior to analysis. Two duplicate samples were taken and analyzed for each profile: one in surface water (near the top of the cast) and one in deep water (near the bottom of the cast). These are used to assist in the assessment of the measurement quality. 3.2.1 Analysis Technique The samples were analyzed using a Single Operator Multiparameter Metabolic Analyzer (SOMMA) developed by K. Johnson (Johnson et al. 1985; 1987). The procedure using this specific instrument is described in detail in the SOMMA operating manual (Johnson 1991 - unpublished manuscript), and a description of the procedure is available in the DOE handbook (DOE 1994). The principle behind this analysis is as follows: A known amount of seawater is dispensed into a stripping chamber where it is acidified and purged with an inert gas. The presence of solid carbonates, such as CaCO3, thus constitutes an interference in the method. The amount of CO2 in the resulting gas stream is determined by absorbing the CO2 in an absorbent containing ethanolamine and titrating coulometrically the hydroxyethylcarbamic acid that is formed. The pH of the solution is monitored by measuring the transmittance of a thymolphthalein indicator at approximately 610 nm. Hydroxide ions are generated by the coulometer circuitry so as to maintain the transmittance of the solution at a constant value. The relevant chemical reactions occurring in the solution are: CO2 + HO(CH2)2NH2 -- HO(CH2)2NHCOO + H+ and H+ + OH- -- H2O. The hydroxide ions used are generated at the cathode by electrolyzing water: H2O + e- -- ½H2(g) + OH- , while silver is dissolved at the anode: Ag(s) -- Ag+ + e- . The overall efficiency of the coulometric procedure is calibrated using known amounts of CO2 gas, either from gas loops or from seawater-based reference materials. 3.2.2 Order of Analyses The samples were analyzed in the order surface-to-deep. This order allowed the cooler deep samples to come to room temperature before they were analyzed. However, this means that it is not possible to ascertain from the analytical measurements alone if there is a systematic variation in the calibration with the life of the coulometric cell (see Sect. 3.2.3 below). 3.2.3 Calibration of the Analyses The calibration of the analyses reported here was problematic. The original plan was to use gas loops to calibrate the coulometer system and to check the performance of the analyses using certified reference materials (CRM Batch 13, certified TCO2 value 2015.13 µmol/kg). Unfortunately, a post-cruise examination of the results showed that the calibration factor calculated for gas loops was unexpectedly variable; an examination of the calibration factor that would have been calculated from the analyses of the CRMs also showed similar variability (equivalent to a standard deviation of measurement of 2.4 µmol/kg). A more detailed examination showed that the variability was restricted to those measurements that had been made in the early stages of a cell's lifetime; measurements on gas loops (Fig. 3 in hard copy) or on CRMs (Fig. 4 in hard copy) made later in the cell's lifetime were much more stable as well as being lower (counts/µmol) than the initial measurements. The reason for this variability appears to be that the cell was not adequately conditioned prior to being calibrated and used (Ken Johnson, BNL, personal communication). Consequently, measurements made early in the cell lifetime are suspect. These include all of the initial gas loop calibrations as well as the initial measurement of the reference material. The early measurements that were made on water from the upper ocean may also be somewhat degraded (see Sect. 3.2.4 below). The calibration approach used to calculate the results presented here was as follows: - The calibration of an individual coulometer was assumed to remain stable from day to day throughout its period of use. This assumption reflects the experience of most investigators (Dickson 1992) and is also borne out by the measurements from this cruise made later in the cell life (see Fig. 3 and Fig. 4). Note that a single coulometer unit was used throughout Leg 1 and for part of Leg 2; it was exchanged during Leg 2 on October 7, 1992, prior to measurement of samples from station 65. - Thus the measurements on reference materials were divided into two groups: one prior to station 65, the other from station 65 to the end of the cruise, and a mean calibration factor was calculated separately for each group of analyses (based on the measurements made on reference materials later in the cell lifetime). - This universal (coulometer dependent) calibration factor (i.e., based on the CRMs) was used to calibrate the measurements made on individual sea water samples. 3.2.4 Measurement Data Quality Because of the difficulty in assigning a meaningful calibration to the analyses of total dissolved inorganic carbon made on this cruise, it is difficult to assess the data quality of the measurements presented here. Although it is apparent that analyses made later in the coulometric cell's lifetime are less variable, it is less clear when the measuring system settles down. Thus the measurements that are made early in the cell lifetime are also necessarily suspect (this is discussed in more detail below). One indication of the potential accuracy of the measurement system is the degree of agreement between the calibration factors based on gas loops and those based on CRMs. The average difference is of the order of 0.1% (Leg 1: 0.14%, Leg 2: 0.06%), thus indicating that the gas loops had the potential of providing an accurate calibration if the cell had been adequately conditioned. The precision of measurement is harder to assess. Duplicate samples were taken at each full station. These were typically a surface sample (in the top 10 m) and a deep sample (usually from one of the two deepest Niskin bottles). The duplicates were analyzed with the surface pair being analyzed at the beginning of a run and the deep pair being split between the beginning and end of a run. The standard deviation of a single measurement calculated from these duplicates was 1.3 µmol/kg for the surface samples (analyzed together); and 2.0 µmol/kg for the deep samples (analyzed at the start and end of a run). However, the standard deviation figures are somewhat misleading. The mean difference for the surface samples (first and second) is 0.4 µmol/kg; that for the deep samples is 1.2 µmol/kg. This suggests that even during the measurement of these duplicates the calibration of the cell is changing in the direction shown in Fig. 3 and Fig. 4. Hence, the measurements on the samples done in the first part of a run, those from the upper ocean, may, on occasion, be biased high by the use of a calibration factor more appropriate to the later measurements. An examination of the data on duplicates indicates that the extent of this bias is unlikely to exceed 4 µmol/kg and may on many occasions be less than that (see Section 3.4 for an evidence from the shore-based replicate measurements). The measurements on the later (deep) samples would be expected to have a precision similar to that found for the later CRMs: a standard deviation of 1.1 µmol/kg (i.e., a similar magnitude to that found for those duplicate measurements that were run side-by-side at the beginning of the run). 3.3 Total Alkalinity Measurements The TALK concentrations were determined by potentiometric titration of 1153 Niskin samples, 574 from Leg 1 and 579 from Leg 2. Samples from throughout the water column were measured on 39 stations (nominally 36 depths per station) and from surface Niskins only on 41 additional stations. The TALK was measured on an aliquot of seawater taken from the same 500-mL bottle previously analyzed for TCO2. Calibration of the shipboard measurements of TALK reported in this numeric data package depends upon the standardization of the HCl titrants with titrations of primary standard sodium carbonate solutions at SIO. The titration system and its calibration are described in Guenther et al. (1994a), a reprint of which is provided in Appendix A of this report. Adjustments to the TALK calibration scale are likely to be made in the future. Data quality was assessed at sea by titration of replicate seawater samples, secondary standard bicarbonate solutions prepared at SIO before expedition, and bottles of CRM batch number 13. Aliquots from the replicate seawater samples and the CRMs were titrated after aliquots had been removed for TCO2 measurements. The short-term repeatability was estimated by analyzing the agreement of pairs of replicate seawater samples titrated simultaneously, using equation (3) in Standard Operating Procedure (SOP) 23 of the DOE (1994). One or two pairs usually were measured on each day of analysis. On Leg 1, for 33 pairs, the sample standard deviation, si, of a single measurement was estimated to be 1.56 µmol/kg. On Leg 2, for 30 pairs, si was estimated to be 2.13 µmol/kg. Two batches of bicarbonate reference materials were titrated during the cruise. Usually four measurements were made per day. Analysis of the results using the normal equation for sample standard deviation yields an estimate of the reproducibility of the measurements over the entire cruise. The si was found to be 2.77 µmol/kg for 75 measurements of batch "A" and 2.03 µmol/kg for 90 measurements of batch "B." Titrations of CRM samples provided an additional estimate of reproducibility and also an estimate of the accuracy through comparison of the at-sea results with the value certified by the laboratory of A. G. Dickson at SIO. The value for CRM batch 13, certified by titrations in 1996 on archived samples, was 2203.79 µmol/kg. During the cruise 84 titrations of CRM batch 13 were made. After 6 measurements were rejected, the si calculated for 78 measurements was 2.29 µmol/kg. The average TALK for the 78 measurements was 2201.26 µmol/kg, nearly within one standard deviation of the certified value. The TALK measurements of seawater reported here have NOT been adjusted by this difference. Figure 5 in the hard copy is a plot of the difference between the shipboard TALK of CRM batch 13 and the certified value versus time during both legs of the cruise. For more detailed information on TALK measurements during the R/V John V. Vickers cruise along WOCE section P13 please see Appendix A in this report. 3.4 Shore-Based Replicate Measurements During the expedition, 322 duplicate samples were collected and returned to SIO for shore-based measurements in the laboratory of C. D. Keeling. A total of 309 TCO2 and 314 TALK measurements were performed on these samples. The 13C/12C isotopic ratio of the carbon comprising the TCO2 was also measured (but not reported in this numeric data package). Comparisons between the shore-based measurements of TCO2 and TALK and those made at sea on water from the same Niskin bottles provide further quality control information on the carbon data set for WOCE Section P13. Shore-based measurements of TCO2 were made by vacuum extraction/manometry using the procedures established for the DOE/WOCE ocean CO2 program (Guenther et al. 1994b). Results are tabulated in Table B.1 in Appendix B. This table also lists the corresponding SOMMA TCO2 values and the differences between the shipboard and shore-based values. Shipboard data are identified as "SIO" and shore-based as "S.I.O." The repeatability of the shore-based results themselves can be estimated from the agreement of the duplicate samples measured (DOE 1994). The sample standard deviation, si, of an individual shore-based result represents the short-term imprecision of the laboratory analysis, together with imprecision introduced by sampling and storage. The si calculated for the set of 140 pairs of data was 0.95 µmol/kg. Twelve pairs were rejected from this calculation, as shown by the flags in Table B.1. This "replicate imprecision" is approximately average for DOE/WOCE program cruises. Of the 140 ship - shore differences corresponding to the "good" pairs of shore-based data, two were rejected for being more than 3si from the average (-17.17 and 20.21 µmol/kg). The average difference for the remaining 138 comparisons was 1.37 µmol/kg, with the shore-based being higher, and the si of an individual difference was 3.11 µmol/kg. The average difference was typical for DOE/WOCE cruises during the 1991-1994 period, but the si is rather large. A reason for the increased scatter is the presence of a depth-dependent bias between the ship shore differences. The usual sampling depths for shore-based replicate samples on DOE/WOCE cruises were surface and deep (nominally 3000 m). Differences for WOCE Section P13 are plotted in Figure 6 for this subset of comparisons. "Surface" samples are the shallowest on a station, ranging from 10 to 75 m in depth, and "deep" samples are the deepest, ranging from 1000 to 3200 m. The average surface deep bias for the subset of surface and deep samples in Figure 6 (18 differences between "good" replicate pairs) is 3.5 µmol/kg (si = 2.5 µmol/kg). A surface deep bias has been evident for only a few other cruises and usually is smaller. On this cruise, shore-based replicate samples were also collected in profile from 9 to 12 Niskin bottles from the surface to nominally 3000 m on 10 stations. Ship shore differences for the top several depths of these stations change toward the more negative deep differences. From 400 m down, the differences are relatively constant. The surface-deep bias results agree fairly well with measurements made at sea. Shipboard measurements for surface comparisons between shore-based and shipboard measurements were made early in the measurement runs, while those for deep comparisons were made late in the runs. Use of the lower calibration factors measured late in the runs resulted in a high bias for measurements made early in the runs (see section 3.2.4). On average, CRM measurements made early in the runs were 2.6 µmol/kg higher than those made late in the runs. Also, deep samples measured early in the runs on Leg 1 on average were 2.3 µmol/kg higher than their duplicates measured late in the runs. However, this pattern was far less apparent for Leg 2. Shore-based measurements of TALK were made by essentially the same potentiometric titration system as the measurements made at sea. The primary difference was that the aliquots for shore-based titrations more often were dispensed gravimetrically into the titration cell, instead of volumetrically. The aliquots were removed from the sample bottles after those for shore-based TCO2 had been removed. Results are tabulated in Table B.2. This table also lists the corresponding shipboard TALK values and the differences between shore-based and shipboard values. As described for the shore-based TCO2, the replicate imprecision of the shore-based TALK measurements is estimated from the agreement of the duplicate measurements. For samples with analyses from both gravimetric and volumetric systems, analyses separated by more than a week of elapsed time were rejected. For one set of titrations made within a few days on both systems, the gravimetric data were chosen over the volumetric. The si was 1.90 µmol/kg for 154 pairs of measurements, with four pairs rejected as shown by the flags in Table B.2. The apparent imprecisions of the shipboard TALK results (see discussion in section 3.3) and the shore-based results are similar, ~2 µmol/kg. The average ship - shore difference for TALK is calculated from 147 of the total of 150 comparisons of "good" shore-based duplicates with corresponding shipboard values. Three comparisons with differences of 18.78, 15.63, and 23.01 µmol/kg (greater than 3si) were rejected. The average difference is 3.35 µmol/kg (shipboard higher). The si of an individual difference is 4.11 mol/kg. Both the average ship shore difference and its imprecision are likely to change after the anticipated adjustments to the TALK calibration scale are made, so further analysis and plotting of the data will not be presented at this time. 3.5 Chlorofluorocarbon Measurements CFCs were usually analysed in the first water sample collected from the 10-L bottles. Care was taken to co-ordinate the sampling of CFCs with other gas samples to minimize the time between the initial opening of each bottle and the completion of sample drawing. In most cases, helium, tritium, dissolved oxygen, TCO2, and TALK samples were collected within several minutes of the initial opening of each bottle. CFC samples were collected in 100-mL precision glass syringes and held immersed in a water bath until processing. The CFC analytical system functioned relatively well during this expedition. The CFC system was installed in a specially designed laboratory van located on a deck and was isolated from possible contamination from the high levels of CFCs that are sometimes present in air inside the ship laboratories. Concentrations of CFCs in air inside this van were usually close to those of clean marine air. Concentrations of CFC-11 and CFC-12 in air samples, seawater, and gas standards during the cruise were measured by shipboard electron capture gas chromatography, according to the methods described by Bullister and Weiss (1988). The concentrations of CFC-11 and CFC-12 in air samples, seawater samples, and gas standards are reported relative to the SIO 1986 calibration scale. CFC concentrations in air and standard gas are reported in units of mole fraction CFC in dry gas and are typically in parts-per-trillion (ppt) range. Dissolved CFC concentrations are given in unit of picomole CFC per kg seawater (pmol/kg). CFC concentrations in air and seawater samples were determined by fitting their chromatographic peak areas to multi-point calibration curves, generated by injecting known volumes of gas from a CFC working standard (PMEL cylinder 71489) into the analytical instrument. These concentrations of CFC-11 and CFC-12 in this working standard were calibrated versus a primary CFC standard (CC36743) before and after the cruise. No measurable drift in the working standard could be detected during this interval. Full range calibration curves were run at 1- to 2-day intervals. Single injections of a fixed volume of standard gas were run much more frequently (at intervals of 1 to 2 hours) to monitor short-term changes in detector sensitivity. The estimated reproducibility of the calibrations is about 1.3% for CFC-11 and 0.5% for CFC-12. A precision (1 standard deviation) for dissolved CFC measurements was ~1%, or 0.005 pmol/kg, whichever is greater. Sample loops filled with CFC-free gas and syringe samples of CFC-free water (degassed in a specially designed glass chamber) were run to check sampling and analytical blanks. CFC-11 and CFC-12 concentrations measured in deep samples along the section were typically in the range of 0 to 0.007 pmol/kg, near the detection limit of the analytical system (~0.004 pmol/kg). Previous studies (Warner et al. 1996) of time-dependent tracers in this region of the Pacific indicate that waters at densities sigma > 27.4 should have CFC concentrations near zero at present. We attribute the low-level CFC signal in deep samples to the slow release of CFC from the walls and O-rings of the 10-L bottles into the seawater sample during storage and to contamination during the transfer and storage of the seawater samples in glass syringes prior to analysis. Based on the median concentrations observed in deep water samples along the section, the following blank corrections were applied to the seawater measurements: CFC-11 blank corrections applied (in pmol/kg): Stations 1 - 43: 0.010 Stations 44 - 88: 0.008 CFC-12 blank corrections applied (in pmol/kg): Stations 1 - 4 0.000 Stations 5 - 23 0.021 Stations 24 - 27 0.034 Stations 28 - 52 0.018 Stations 53 - 88 0.009 As a result of these blank corrections, some concentrations reported for deep samples are less than zero. A number of water samples had anomalous high CFC-11 and/or CFC-12 concentrations relative to adjacent samples. These high values appeared to occur more or less randomly and were not clearly associated with other features in the water column (e.g., elevated oxygen concentrations). In most cases, only one of the two CFCs measured showed these anomalous high levels. This suggests that the high values were the result of analytical variability or isolated low-level contamination events. These samples are included in this report and are flagged as either "3" (questionable) or "4" (bad) measurements. Approximately 181 analyses of CFC-11 and 76 analyses of CFC-12 were given these flags. 4. DATA CHECKS AND PROCESSING PERFORMED BY CDIAC An important part of the numeric data packaging process at the Carbon Dioxide Information Analysis Center (CDIAC) involves the quality assurance (QA) of data before distribution. Data received at CDIAC are rarely in a condition that would permit immediate distribution, regardless of the source. To guarantee data of the highest possible quality, CDIAC conducts extensive QA reviews that involve examining the data for completeness, reasonableness, and accuracy. The QA process is a critical component in the value-added concept of supplying accurate, usable data for researchers. The following information summarizes the data processing and QA checks performed by CDIAC on the data obtained during the R/V John V. Vickers cruise along WOCE Section P13 in the Pacific Ocean. 1. The final carbon-related data were provided to CDIAC by A. G. Dickson, P. R. Guenther, and C. D. Keeling of Scripps Institution of Oceanography. The final hydrographic and chemical measurements and the station information files were provided by the WOCE Hydrographic Program Office (WHPO) after quality evaluation. A FORTRAN 90 retrieval code was written and used to merge and reformat all data files. 2. To check for obvious outliers, all data were plotted by use of a PLOTNEST.C program written by Stewart C. Sutherland (Lamont-Doherty Earth Observatory). The program plots a series of nested profiles, using the station number as an offset; the first station is defined at the beginning, and subsequent stations are offset by a fixed interval ionable measurement) or "4" (bad measurement) (see File Descriptions in Part 2 of this documentation). 3. To identify "noisy" data and possible systematic, methodological errors, property-property plots for all parameters were generated, carefully examined, and compared with plots from previous expeditions in the Pacific Ocean. 4. All variables were checked for values exceeding physical limits, such as sampling depth values that are greater than the given bottom depths. 5. Dates, times, and coordinates were checked for bogus values (e.g., values of MONTH < 1 or > 12; DAY < 1 or > 31; YEAR < or > 1992; TIME < 0000 or > 2400; LAT < -10.000 or > 60.000; and LONG < 160.000 or > 170.000). 6. Station locations (latitudes and longitudes) and sampling times were examined for consistency with maps and cruise information supplied by A. Dickson and C. Keeling of SIO. 7. The designation for missing values, given as -9.0 in the original files, was changed to -999.9 for the consistency with other oceanographic data sets. 5. HOW TO OBTAIN THE DATA AND DOCUMENTATION This database (NDP-075) is available free of charge from CDIAC. The complete documentation and data can be obtained from the CDIAC oceanographic Web site (http://cdiac.esd.ornl.gov/oceans/doc.html), through CDIAC's online ordering system (http://cdiac.esd.ornl.gov/pns/how_order.html), or by contacting CDIAC. The data are also available from CDIAC's anonymous file transfer protocol (FTP) area via the Internet. Please note that your computer needs to have FTP software loaded on it (this is built in to most newer operating systems).
