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

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.
