pmel8689.dat-rt3_89.dat (Files 3-15)

These 13 data files contain CO2 measurements, hydrographic measurements, and the calculations of in situ fugacities of CO2 for PMEL cruises conducted from 1986-1989. All 13 data files have the same format and can be read by using the following FORTRAN 77 code [contained in pmeldat.for (File 2)]:

       INTEGER DAY, YEAR 
       CHARACTER CRUISE*19, MONTH*3, FLAG*1
       REAL DAYGMT, LAT, LONG, DIST, TEMP, WARM, SAL, APRE
       REAL XCO2A, XCO2SW, FCO2A, FCO2SW

     1 LONG, DIST, TEMP, WARM, SAL, APRE, XCO2A, XCO2SW, FCO2A, 
     2 FCO2SW, FLAG

Where:

CRUISE  -  is the cruise name;
DAY  -  is the day of sampling (GMT);
MONTH  -  is the month of sampling;
YEAR  -  is the year of sampling;
DAYGMT  -  is the day of the year [expressed in decimal time (GMT)];
LAT  -  is the latitude of the sampling location (decimal degrees; negative values indicate the Southern Hemisphere);
LONG  -  is the longitude of the sampling location (decimal degrees; negative values indicate the Western Hemisphere);
DIST  -  is the cumulative distance since the first sampling location on the leg (km);
TEMP  -  is the sea-surface temperature (°C);
WARM  -  is the warming temperature [indicates the degrees of warming (°C) for seawater as it transited from the intake line to analysis site];
SAL  -  is the sea-surface salinity [Practical Salinity Scale (PSS)];
APRE  -  is the atmospheric pressure (mbar);
XCO2A  -  is the observed mole fraction of CO2 in air [ppm (dry air)];
XCO2SW  -  is the observed mole fraction of CO2 in surface water [corrected for warming, ppm (dry air)];
FCO2A  -  is the calculated in situ fugacity of CO2 in air [µatm (moist air)];
FCO2SW  -  is the calculated in situ fugacity of CO2 in surface water [corrected for warming, µatm (moist air)];
FLAG  -  is the data quality flag:
2 = Acceptable measurements of X(CO2)sw;
3 = Questionable measurements of X(CO2)sw;
5 = Data were not reported;
P = Questionable latitude and/or longitude;
Missing values for variables are represented by -999.9.
