     This data documentation discusses the procedures and methods used to obtain data on total
     carbon dioxide (TCO2), total alkalinity (TALK), and discrete partial pressure of CO2 (pCO2)
     during the Research Vessel (R/V) Meteor Expedition 15/3 in the South Atlantic Ocean  (Section
     A9).  Conducted as part of the World Ocean Circulation Experiment (WOCE), the cruise began
     in Vitoria, Brazil, on February 10, 1991, and ended in Pointe-Noire, Congo, on March 23, 1991. 
     WOCE zonal Section A9 began at ~38W and continued along the 19S parallel until ~8E. 
     Samples were collected for TCO2 from 28 stations along the 19th parallel and at 3 diversions
     north and south of the 19th parallel.  The latter stations were occupied to track bottom water
     movements.  Measurements made along WOCE Section A9 included pressure, temperature,
     salinity, and oxygen measured by conductivity, temperature and depth sensor (CTD); bottle
     salinity, oxygen, phosphate, nitrate, nitrite, silicate, CFC-113, CCl4, CFC-12, CFC-11, TCO2,
     TALK, and pCO2 measured at 20 C.  Replicate samples from ten Niskin bottles at four stations
     were also collected for later shore-based reference analyses of TCO2 and TALK by vacuum
     extraction and manometry in the laboratory of Dr. Charles Keeling, Scripps Institution of
     Oceanography (SIO).
      
     The TCO2 was measured using an automated sample processor (SOMMA) for extracting CO2
     from seawater samples coupled to a Coulometer for detection of the extracted gas.  The precision
     and accuracy of the system was +/-1.0 umol/kg.  R/V Meteor Cruise 15/3 was an initial test of an
     experimental system for measuring pCO2 on discrete water samples: a batch equilibration
     technique was used followed by headspace gas chromatography with flame ionization detection. 
     While the quality of some pCO2 data is poor compared with that collected more recently (i.e.,
     precision and accuracy ~2-3%), all data have been included for completeness.  Samples collected
     for TALK were measured using standard potentiometric techniques; precision was +/-2.6 umol/kg. 
       
     The R/V Meteor Cruise 15/3 data set is available free-of-charge as a numeric data package
     (NDP) from the Carbon Ddioxide Information Analysis Center (CDIAC). The NDP consists of
     two oceanographic data files, two FORTRAN 77 data retrieval routine files, a documentation file, and this
     printed documentation, which describes the contents and format of all files as well as the
     procedures and methods used to obtain the data.

                                       OVERVIEW                 

     1. BACKGROUND INFORMATION
     
     The increase in atmospheric carbon dioxide (CO2) concentrations (as well as in other
     radiatively active trace gases) because of human activity has produced serious concern regarding
     the heat balance of the global atmosphere (Moore and Braswell 1994).  The increasing
     concentrations of these gases may intensify the earth's natural greenhouse effect, and force the
     global climate system in ways that are not well understood.  The oceans play a major role in
     global carbon cycle processes.  Carbon in the oceans is unevenly distributed because of complex
     circulation patterns and biogeochemical cycles, neither of which are completely understood.
     
     To better understand the ocean s role in climate and climatic changes, several large
     experiments have been conducted in the past, and others are currently under way. The World
     Ocean Circulation Experiment (WOCE) is a major component of the World Climate Research
     Program.  Although total carbon dioxide (TCO2) is not an official WOCE measurement, a
     coordinated effort, supported in the United States by the U.S. Department of Energy (DOE), is
     being made on WOCE cruises (through 1998) to measure the global, spatial, and temporal
     distributions of TCO2 and other carbon-related parameters.  The CO2 survey goals include
     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 the subsequent assessment of the anthropogenic
     CO2 increase in the oceans.  The CO2 survey is taking advantage of the sampling opportunities
     provided by the WOCE cruises during this period.  The final data set is expected to cover ~23,000
     stations.
      
     This document describes the first effort by chemical oceanographers from Brookhaven
     National Laboratory (BNL) to make high-quality CO2 measurements during a 42-day expedition
     in the South Atlantic Ocean aboard the Research Vessel (R/V) Meteor in the austral summer of
     1991.  Designated as WOCE Expedition code 06MT15/3, the cruise departed Vitoria, Brazil, on
     February 10, 1991, and arrived in Pointe-Noire, Congo, on March 23, 1991.  The WOCE zonal
     Section is A9.                                                 
    
     The CO2 investigation during R/V Meteor Cruise 15/3 was supported by DOE grant DE-ACO2-76CH00016.
     

     2. DESCRIPTION OF THE EXPEDITION
     

     2.1 R/V Meteor, Technical Details and History 
     
     The R/V Meteor is owned by the Federal Republic of Germany through the Ministry of
     Research and Technology (BMFT), which financed its construction.  It is operated by the German
     Research Foundation (DFG), which provides about 70% of its operating funds (the BMFT supplies
     the remainder).  DFG also plans the scientific cruises and appoints the chief scientists.  The
     Operations Control Office of the University of Hamburg is responsible for management, logistics,
     execution and supervision of ship operations.  These functions are exercised by direct cooperation
     with expedition coordinators and the managing owners, the Reedereigemeinschaft
     Forschungsschiffahrt GmbH, located in Bremen, Germany.  The latter is responsible for hiring,
     provisioning, and coordinating ship maintenance.  Used for ocean research, primarily in the
     Atlantic and Indian Oceans, the R/V Meteor routinely carries scientists from many different
     countries.  The Meteor was completed in 1986 in Travemunde, Germany.  The basic features of
     the vessel follow:

      Meteor (I) was constructed in 1925, the first research and survey vessel of that name.  Owned
     by the German navy, it was based in Wilhelmshaven.  One of its first expeditions was the German
     Atlantic Ocean Expedition of 1925-1927, which was  organized by the Institute of Marine
     Research in Berlin.  Thereafter, the vessel was used for German physical, chemical, and
     microbiological marine investigations and for navy surveying and fisheries protection duties. 
   
     Meteor (II) was planned after the 1950s; it was operated by the Deutsche
     Forschungsgemeinschaft (German Science Community) in Bad Godesberg and the Deutsches
     Hydrographisches Institut (German Hydrographic Institute) in Hamburg.  Commissioned in 1964,
     Meteor (II) participated in the International Indian Ocean Expedition. 
      
     Multipurpose Meteor (III), used on the cruise described in this documentation, was completed
     in 1986, replacing Meteor (II).  Based in Hamburg, it is used for German ocean research
     worldwide and for cooperative efforts with other nations in this field.  The vessel serves scientists
     of all marine disciplines in all of the world's oceans.

     2.3 Brief Cruise Summary
     
     Gerold Siedler relieved Walter Zenk as chief scientist upon completion of the R/V Meteor
     Cruise 15/2 on February 8, 1991, in Vitoria, Brazil; the remaining participants were on board by
     February 9.  Equipment setup began on February 8.  The R/V Meteor departed Vitoria at 9 am
     on February 10, 1991, and steamed to its initial position of 19S, 38W.  On February 11 the
     ship began a short zonal section across the Brazil Current characterized by closely spaced
     expendable bathythermograph (XBT) launches and acoustic Doppler current profiling (ADCP). 
     A test station was made to check CTD operation and  possible contamination of the 10-liter
     Niskin bottles for CFCs.  From these results and the earlier profiles, a decision was made to run
     westward to the 500-m isobath where the Section A9 began with a set of eight closely spaced
     expendable current profiler (XCP) and CTD profiles including the standard measurements
     (nutrients, O2, CO2, tracers) as the ship steamed once again eastward across the Brazil Current and
     into the open ocean along 19S.  Neither tracer nor CO2 samples could be taken on all CTD
     stations because of the time required for analysis.  The density of the CO2 sampling was gradually
     increased during the first week until at least one CO2 station was completed each day.  Initial
     delays were aggravated by high (+ 3 to 10 umol/kg) TCO2 results for the certified reference
     material (CRM) analyses with respect to the certified value.  It was initially assumed that the
     problem lay with the SOMMA-Coulometer system or its software, and time was lost
     troubleshooting.  After analyzing a limited number of samples from an earlier CRM batch (see
     Table 1 on page 13) over several days, it was found that the measurement system was operating
     properly and that the new CRM batch supplied especially for the cruise was  at fault.  This was
     confirmed by subsequent testing.
     
     To compare these data with data from the earlier U.S. South Atlantic Ventilation Experiment
     (SAVE) Program, the normal station routine (i.e., every 30 nm) was interrupted at 25  W between
     February 19 and 20 for an additional three stations north and south of 19S.  To identify deep
     water movements on the western edge of the Mid-Atlantic Ridge, between February 25 and 27
     a short meridional section comprising seven stations was carried out from 19 00'S to 23 40'S. 
     Between March 3 and 6 the ship veered slightly southward to avoid the 200-mile commerce zone
     belonging to the island of St. Helena (United Kingdom).  Between March 12 and 15 a diversion
     was made at 7E to the Walvis Ridge, and eight CTD stations were taken along a track parallel
     to the ridge to study deep water movements in this region.  The ship continued the zonal section
     along 19S until ~8E where a course change to east-northeast was made.  To adequately sample
     the eastern boundary current up to the continental shelf, the distance between stations at this point
     was reduced from 30 to 10 nm.  On March 19, 1991 WOCE Zonal Section A9 was completed. 
     The ship steamed to Pointe-Noire, Congo, arriving on March 23, 1991.  Weather and sea
     conditions were excellent throughout the cruise.
     

     3. DESCRIPTION OF VARIABLES AND METHODS 
     
     The data file met153.dat (see description in Part 2) in this numeric data package (NDP)
     contains the following variables: station numbers; cast numbers; sample numbers; bottle numbers;
     CTD pressures, temperatures, salinities, and oxygen; potential temperatures; bottle salinities;
     concentrations of dissolved oxygen, silicate, nitrate, nitrite, and phosphate; TCO2 and TALK
     concentrations; partial pressure of CO2 (pCO2) measured at 20 C; CFC-113; CCl4; CFC-12; CFC-11;
     and quality flags.  The station inventory file m153sta.inv (Part 2) contains expocodes, section
     numbers, station numbers, cast numbers, sampling dates (i.e., day, month, year), sampling times,
     latitude, longitude, and bottom depth for each station.
     
     Water samples were collected by a General Oceanics rosette equipped with 24 10-L bottles
     mounted on a Neil Brown Mark III CTD instrument (IFMK numbers NB3 and NB2) equipped
     with an O2 sensor and bottom alarm.  Using IFMK software by L. Bellach, pressure, temperature,
     conductivity, oxygen, and sensor temperature data were recorded on a PC at the full sampling rate
     of 32 Hz in binary form and at a reduced sampling rate of 3 Hz on a Micro Vax computer. 
     Reversing thermometers were included on bottles 1 and 23 (deepest and mixed-layer sample); each
     rack consisted of three thermometers. The CTD pressure, temperature, oxygen, and conductivity
     data were processed and corrected according to laboratory calibrations in 1990 and 1991, and in
     situ measurements, according to procedures written by Ruhsam (1994) and Siedler and Zenk
     (1992).  Pressure values are expected to be accurate to +/-3 dbar; temperature to +/-0.002 C. 
     Salinity for selected Niskin bottles (about one in every three) was also determined on a Guildline
     Autosal model 8400A, that was standardized weekly with International Association for the
     Physical Sciences of the Ocean (IAPSO) water (batch P112).  These data were also used to
     process the CTD data, and the final salinity data are expected to be accurate to +/-0.002 on the
     Practical Salinity Scale (PSS).  Oxygen was determined on each Niskin bottle by the Winkler
     method as modified by Grasshoff et al. (1983).  Duplicates were taken periodically to estimate the
     accuracy and precision of the entire sampling procedure, which was determined to be +/-1 umol/kg. 
     The concentrations of nitrate, nitrite, phosphate, and silicate dissolved in seawater were
     determined on a continuous flow analyzer: the Alpkem Corporation RFA 300, which was used
     in conjunction with a data acquisition system supplied by Oregon State University.  The analyses
     were completed within 24 h after sampling.
     
     The TCO2 was determined using an automated coulometric system (SOMMA) (Johnson et
     al. 1985; Johnson et al. 1987; Johnson and Wallace 1992).  Some 753 individual samples, along
     with 145 duplicates from 29 stations, were collected in 300-mL precombusted (450 C for
     24 h) bottles and immediately poisoned with HgCl2 according to the DOE Handbook of Methods
     (DOE 1994).  Before analysis, samples were kept in darkness until thermally equilibrated to the
     pipette temperature.  CRM supplied by Andrew G. Dickson, of SIO (DOE 1994), were also
     analyzed.  CRMs are filtered sterile salt solutions or seawater spiked with Na2CO3, analyzed for
     TCO2 concentration by vacuum-extraction/manometry in the laboratory of Charles D. Keeling at
     SIO. 
         
     For analysis, seawater  introduced from an automated  To Deliver  pipette into a stripping
     chamber was acidified, and the resultant CO2, after drying, was coulometrically titrated on a model
     5011 UIC coulometer.  In the coulometer cell the hydroxyethylcarbamic acid, formed from the
     reaction of CO2 and ethanolamine, was titrated coulometrically (electrolytic generation of OH ) with 
     photometric endpoint detection.  The product of the time and the current passed through the
     cell during titration was related by Faraday s constant to the number of moles of OH  generated,
     and thus to the moles of CO2 that reacted with ethanolamine to form the acid.  For system
     calibration, a gas calibration procedure using pure CO2 was built into the SOMMA.  The hardware,
     located upstream of the stripper, consisted of an eight-port Gas Sampling Valve (GSV) with two
     sample loops connected to a source of pure CO2 through an isolation valve; the vent side of the
     GSV was plumbed to a barometer.  When a gas loop was filled with CO2, the mass (moles) of
     CO2 contained therein was calculated by dividing the loop volume (V) by the molar volume of
     CO2 at the ambient T and P.  The molar volume of CO2 [V(CO2)] was calculated  iteratively from
     the expression:
     
                                  V(CO2) = RT / P[1+ B(T) / V(CO2)] ,
     
     were P is the instantaneous barometric pressure, T is the loop temperature, and B(T) is the first
     virial coefficient for pure CO2.  The ratio of the calculated mass to that determined coulometrically
     was the gas calibration factor (CALFAC) used to correct the subsequent titrations for small
     departures from 100% theoretical response.  The volume of the loops was determined
     gravimetrically with deionized water by the method of Wilke et al. (1993).     
         The "to deliver"  volume (TDV) of the SOMMA sample pipette was determined
     gravimetrically with milli-Q deionized water degassed with helium.  The thermostatted sample
     pipette was filled with water at the same temperature and then discharged into preweighed 50-mL
     serum bottles that were reweighed on a model R300S (Sartorius, G ttingen, Germany) balance. 
     The apparent weight (g) of water collected (Wair) was corrected to the mass in vacuo (Mvac) from
     
                             Mvac = Wair + Wair (0.0012/d - 0.0012/8.0) ,
     
     where 0.0012 is the sea level density of air at 1 atm, d is the density of the calibration fluid at the
     pipette temperature and sample salinity, and 8.0 is the density of the stainless steel weights.  The
     TDV was
     
                                              TDV = Mvac /d .
     
     The precruise calibrated TDV of the pipette was 28.7113 +/-0.003 mL (n = 8) at 20 C.  During
     the cruise, 52 preweighed serum bottles were filled from the pipette.  They were sealed and
     returned to the laboratory for reweighing.  The mean volume from these bottles was 28.7172  
     +/- 0.0096 at 20 C.  The mean difference between the precruise and postcruise results was 0.0059 mL
     which is less than the standard deviation of the 52 postcruise weighings; accordingly, TCO2 was
     calculated using the precruise volume of 28.7113 mL.                  
         
     An IBM compatible personal computer with two RS232 serial, a 24-line digital input/output,
     and analog-to-digital ports was used to control the coulometer, barometer, solid state control
     relays, and temperature sensors, respectively.  The temperature sensors (model LM34CH, National
     Semiconductor, Santa Clara, California) with a voltage output of 10 mV/ F were calibrated against
     thermistors certified to 0.01 C (PN CSP60BT103M,  Thermometrics, Edison, New Jersey) with
     a certified mercury thermometer as a secondary standard.  These sensors monitored the pipette,
     gas sample loop, and the coulometer cell temperatures.  The barometer, model 216B-101
     Digiquartz Transducer (Paroscientific, Inc., Redmond, Washington) was factory-calibrated for
     pressures between 11.5 and 16.0 psia.  The SOMMA software was written in GWBASIC Version
     3.20 (Microsoft Corp., Redmond, Washington), and the instrument was driven from an options
     menu appearing on the personal computer monitor.
         
     Titrations were done with the coulometer in the counts mode: the total charge passed during
     a titration was displayed as the total number of counts accumulated by the coulometer's voltage-
     to-frequency converter (VFC).  From the factory calibration of the VFC [frequency = 105 pulses
     (counts) generated per second at 200 mA] and the value of a Faraday (96489 coulomb/mol), a
     scaling factor of 4.82445 x 103 counts per micromole was derived, and the micromoles (M) titrated
     were
     
                                M = counts/4824.45 - (blank x TT) ,
     
     where TT was the length of the titration in minutes and blank was the system blank in micromole
     per minute.  The total carbon dioxide concentration in  mol/kg was calculated as follows:
     
                                 TCO2  =  [M(CALFAC)(1000/TDVC x p)] x 1.00017 ,
     
     where CALFAC is the gas calibration factor, TDVC is the  to deliver  volume of the pipette in
     milliliters corrected for the thermal expansion of glass, p is the density of sea water in kilograms
     per liter from the equation of state (Millero and Poisson 1981), and 1.00017 corrects for the
     dilution of the sample by addition of 100 uL of HgCl2 solution to the 300-mL sample bottle. 
     Precision for a set of analyzed samples was expressed as the square root of the pooled variance
     (Sp2).
 
     The precision for the A9 samples was estimated from 90 replicates collected from 18 deep-
     water samples analyzed throughout the cruise.  The Sp2 was +/- 0.83 umol/kg (Johnson et al. 1993). 
     Analytical accuracy was verified by the analysis of 11 CRMs (batch 2) during the cruise; certified
     TCO2 was 1978.78 +/-0.93 (n = 9) umol/kg.  The mean and standard deviation for the CRM
     analyzed at sea on the SOMMA was 1978.1 +/-0.82 umol/kg.  Table 1 lists the CRM data.  Note
     the excellent agreement between Sp2 obtained from sample duplicates ( +/-0.83 umol/kg) and the
     CRM precision (+/-0.82 umol/kg) and the close agreement between the CRM results for February
     13 and those for March 20 some 6 weeks later.  Unfortunately, only 11 CRM from batch 2 were
     available for analysis.  Because the batch 3 CRMs supplied for the cruise were found to be
     unstable and uncertifiable, data from this batch cannot be used to evaluate the performance of the
     TCO2 measurement system.

                    The CRM had a certified TCO2 of 1978.8 umol/kg and salinity of 33.361 PSS.

     Replicate samples from ten Niskin bottles at four stations were also collected for later shore-
     based reference analyses of TCO2 by vacuum extraction and manometry by Charles D. Keeling,
     SIO.  The results (Table 2), extracted from Guenther et al. (1994), were obtained very early in the
     program for comparing shipboard analyses by coulometry with shore-based analyses of duplicate samples,
     and many mistakes and false starts were noted. For example, experimentation with the most suitable
     sample bottle for this purpose was not yet completed, nor storage precautions or expedited shipping 
     procedures been worked out.   Therefore, some of the differences in the
     seven completed comparisons listed in Table 2 probably resulted from unfamiliarity with the new
     RODAVISS glass bottle stoppers: some breakage was caused by overtightening; some loss of CO2,
     by undertightening of the stoppers.  Nor were the storage conditions optimal for the data quality
     of the surviving samples: they were kept in a non-air-conditioned cargo hold for the remainder
     of R/V Meteor Cruise 15/3 and then transported to Brazil before they could be shipped to SIO. 
     Temperature sensors were not included in the shipping crates, as is now standard operating
     procedure; however, temperatures likely exceeded an unacceptable 30 C in either the cargo hold
     during the R/V Meteor s return voyage to Brazil or in Brazil prior to shipment to SIO. 
      
     TALK samples were collected and poisoned with 50 uL of saturated solution of HgCl2 in
     250-mL, standard borosilicate glass, screw-cap bottles.  They were stored at room temperature and
     returned to Woods Hole for TALK analysis.  TALK was determined by potentiometric titration;
     a method derived from one first described by Dyrssen (1965) and later modified by Bradshaw et
     al. (1981) was used.  The automated titration was performed in a closed cell maintained at
     constant temperature (25 +/-0.1 C); to be similar to seawater, the ionic strength of the hydrochloric
     acid solution (0.1 N) was adjusted with NaCl.  The ratio of the acid normality over the cell
     volume was calibrated before and after the sample analysis.  The calibration consisted of preparing
     solutions of known TALK concentration and measuring them as described by Brewer et al. (1986). 
     The precision of the measurements was estimated to be better than 0.1%.  The samples were likely
     exposed to relatively high temperatures during shipment from Brazil to Woods Hole.  Some
     sample bottles were also broken during shipment.  Overall precision of the data set was therefore
     slightly degraded from that expected from measurement error alone.  The pooled standard
     deviation for ten replicate samples was ~0.12%.

     pCO2 was measured using an experimental analytical system employing a batch-equilibration,
     static headspace analysis technique, with detection by gas chromatography and a flame ionization
     detector.  Subsequently, this technique has been greatly improved and a full description is
     presented by Neill et al. (1995).  During the R/V Meteor Cruise 15/3, the developing technique
     gave less than optimum data quality for this parameter because not all sources of error were
     known.  The data are presented primarily for completeness, and caution must be exercised in their
     quantitative interpretation.
      
     Briefly, the technique used was based on the static headspace methane method of Johnson
     et al. (1990).  Samples were collected in 60-mL serum bottles rinsed and filled to overflowing at
     the Niskin bottle.  These samples were transported to a box that was purged with a flow of 350
     ppm CO2 in argon.  A headspace of ~ 5-mL was introduced using a disposable pipette-tip attached
     to a special tool (Johnson et al. 1990).  The headspace was purged briefly with the argon-CO2
     mixture, and a septum was placed over the serum bottle neck and crimped tightly with an
     aluminum cap.  Headspace overpressure from crimping was relieved by piercing the septum with
     a needle for 3 to 4 seconds.  The samples were equilibrated for 4 to 6 hours in the dark in a
     shaking water bath at 20 C.  The experiments performed at sea indicated that there was no
     significant difference in the measured pCO2 of replicate samples equilibrated for periods from 2
     to 9 hours.  Following equilibration, the septum was pierced with two needles.  The longer needle
     was inserted to the bottom of the serum bottle to dispense a brine solution, while the shorter one
     penetrated just below the septum into the headspace.  Approximately 4 mL of brine solution was
     injected into the bottle through the longer needle displacing the headspace through the shorter 
     one to purge and fill a small (400 uL) gas sample loop attached to the gas chromatograph.  After
     filling, the loop was allowed to come to atmospheric pressure, temperature and pressure were
     recorded, and the contents were injected onto a 6 ft x 1/8 in. stainless steel chromatographic
     column packed with Porapak N.  A methanizer column containing a nickel catalyst (Varian Inc.)
     mounted in the injector block of the gas chromatograph at 325 C on the terminal end of the
     column was used to quantitatively convert CO2 to CH4 for detection by flame ionization.  Carrier
     gas flow rate was 30 mL/min of ultra high purity nitrogen; the methanizer was supplied with
     hydrogen from a hydrogen generator at 30 mL/min.  The flame ionization detector was supplied
     with compressed air and hydrogen at 300 and 30 mL/min, respectively.
      
     The variety of septa used were found to leak during equilibration, after they had been pierced
     with needles.  To calculate the partial pressure of CO2 after equilibration, it is usually necessary
     to measure or calculate the pressure of equilibration because of the phase redistribution of gases
     dissolved in seawater.  Subsequent testing with a wide variety of septa and improved technique
     showed that the pressure of equilibration can be calculated or measured accurately when the septa
     do not leak.  However, septa used during R/V Meteor Cruise 15/3 consistently leaked, so that the
     pressure of equilibration was the same as the ambient atmospheric pressure.
      
     To calculate the pCO2 of the equilibrated samples, the area of the CO2 peak was converted
     to a mole fraction of CO2 within the headspace from temperature and pressure measurements, and
     a calibration curve was obtained from injections of gas-phase CO2 standards at nominal levels of
     250, 350, 750, and 1500 ppmv.  Subsequently, these standards were intercalibrated against primary
     standards maintained at the Lamont-Doherty Earth Observatory.  The mole fraction of CO2 at the
     measured atmospheric pressure was converted to the partial pressure of CO2 after equilibration. 
     From the measured (unequilibrated) sample TCO2 (SOMMA), the original CO2 content of the
     introduced headspace, and the CO2 content after equilibration, the mass of CO2 transferred from
     the liquid to the gas phase, or vice versa, was calculated and used to calculate  the sample TCO2
     after equilibration.  From TCO2 and the measured pCO2, the TALK was calculated.  TALK was
     assumed to be conservative, and from the TALK - TCO2 pair the pCO2 of the water sample at 20 C
     prior to equilibration was calculated by using the thermodynamic constants of Roy et al. (1993),
     Weiss (1974), and published procedures (DOE 1994).  In the data files pCO2 is reported at a
     standard temperature of 20 C.  Actual equilibration temperatures generally ranged from 19.9 C
     to 20.2 C.
     
     Precision varied throughout the cruise, depending primarily on the status of the catalyst, that
     had to be reconditioned periodically.  Precision on multiple (>3) replicates varied from 0.4 to ~6%
     and averaged 2%.  Accuracy was judged in three ways. First, throughout the cruise the mole
     fraction of CO2 in air was measured; air was collected in syringes at the bow of the ship during
     steaming between stations.  The mean pCO2 of the air, expressed as a dry air mole fraction, was
     353.6 (+/-9.74); this compares well with contemporary measurements of 353.5 and 352.9 made by
     the National Oceanic and Atmospheric Administration Climate Monitoring and Diagnostics
     Laboratory air sampling network in February and March 1991 on air samples collected at
     Ascension Island (7 55'S and 14 25'W) (Conway et al. 1994).  This agreement suggested that
     although instrument imprecision was high, the overall accuracy of the measurements was
     consistent with a completely independent set of measurements.  Second, assessment of accuracy
     arose from samples overdetermined for the carbonate system.  In this case, the TALK by
     potentiometric titration for samples from two stations was compared with the TALK calculated
     from the measured pCO2 TCO2 pair.  TALK calculated from the pCO2-TCO2 pair was 4 umol/kg
     ( +/- 12) lower than the measured TALK for these stations.  Once again, this suggested relatively
     good accuracy but poor precision.  Third, overall assessment of accuracy was made by comparing
     the discrete-pCO2 measurements with measurements made by Lamont-Doherty Earth Observatory
     (LDEO).  Station 199 (19S, 2W) of Meteor Cruise 15/3 was compared with Station 144 (20S, 1W) of 
     the SAVE expedition, at which a discrete-pCO2 profile had been collected during
     February 1988 by D. Chipman and T. Takahashi of LDEO.  The respective profiles show very
     good agreement within the Angola Basin Deep Waters (>2000 m).  For this depth range,
     the R/V Meteor 15/3 mean value of pCO2 at 20 C was 801 (+/-10) compared with a SAVE value
     of 786 (+/-11).  In the upper waters, systematic differences were noted between the two profiles;
     however, these can be seen in the TCO2 data as well. 
     
     
     Exploratory measurements of anthropogenic halocarbon compounds [CCl4, CCl2FCClF2
     (CFC-113), CCl3F (CFC-11), and CCl2F2 (CFC-12)] were made using a new analytical
     technique on R/V Meteor Cruise 15/3  (Wallace et al. 1994).  The new method was jointly
     developed by BNL, Bedford Institute of Oceanography (Canada), and Chalmers University of
     Technology (Sweden).  Briefly, it employs a purge-and-trap extraction technique similar to that
     used in previous CFC analysis systems (Gammon et al. 1982; Wallace and Moore 1985; Bullister
     and Weiss 1988).  The most significant differences from the earlier technique were:
     
     1.The chromatographic column used was a wide-bore DB-624 glass capillary (J&W; 70 m  
       0.53 mm OD; 3-um film) which gives baseline resolution between the tracer compounds of
       interest and a variety of natural and anthropogenic halocarbons.
     
     2.The purged volatile compounds were trapped on a short Porapak N column kept at ambient
       temperature (~20 C).  This eliminated the need for taking cryogenic systems to sea.  Because
       CFC-11 and CFC-12 were measured separately by a group from the university of Bremen,
       the BNL system was optimized for measuring low levels of CCl4, CH3CCl3, and CFC-113
       by using a 20-mL water sample and increasing the purge-gas flow to 5 min at 60 mL/min. 
       Extraction efficiency was > 99% for all compounds except CH3CCl3 (~85%).  These
       conditions caused CFC-12 to approach breakthrough on the trap, decreasing precision and
       accuracy for this compound.  Hence, all CFC-12 (and most CFC-11) data in this NDP are
       based on measurements obtained by using the separate packed column system, which
       employed low-temperature trapping.
     
     Two unexpected problems were encountered: a partial chromatographic interference for CFC-113
     due to extremely high levels of CH3I in tropical near-surface waters and a second, more
     serious problem, arising from a buildup of water on the column, which caused large negative
     peaks and an interfering baseline shift in the vicinity of the CFC-113 peak.  Both of these
     problems have subsequently been corrected; however, they greatly reduced the number of samples
     that could be obtained. 

      4. DATA CHECKS AND PROCESSING PERFORMED BY CDIAC
     
     An important part of the NDP 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.  Although they
     have common objectives, these reviews are tailored to each data set, often requiring extensive
     programming efforts.  In short, the QA process is a critical component in the value-added concept
     of supplying accurate, usable data for researchers. 
      
     The following summarizes the data-processing and QA checks performed by CDIAC on the
     data obtained during the R/V Meteor Expedition 15/3 in the South Atlantic Ocean.
     
     1. Carbon-related data and preliminary hydrographic measurements were provided to CDIAC 
        by K. M. Johnson and D. W. R. Wallace of BNL. 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 77 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 (LDEO).  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.
     
     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 South Atlantic 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  > 1991; TIME < 0000 or > 2400; LAT <  25.000
        or > 17.000; and LONG <  40.000 or > 12.000).
     
     6. Station locations (latitudes and longitudes) and sampling times were examined for consistency
        with maps and with cruise information supplied by K. M. Johnson and D. W. R. Wallace,
        BNL.   
     
     7. The designation for missing values, given as  -9.0 in the original files, was changed to
        -999.9.

                                    CONTENT AND FORMAT OF DATA FILES   

     7. FILE DESCRIPTIONS
     
     This section describes the content and format of each of the five files that comprise this NDP
     (see Table 3).  Because CDIAC distributes the data set in several ways (e.g., via anonymous FTP,
     floppy diskette, and on 9-track magnetic tape), each of the five files is referenced by both an
     ASCII file name, which is given in lower-case, bold-faced type (e.g., ndp051.txt) and a file number. 
     The remainder of this section describes (or lists, where appropriate) the contents of each file.  
     The files are discussed in the order in which they appear on the magnetic tape.
     
ATTENTION! Datafiles for A09 section were  updated, refomatted, and renamed on 03/20/2003
