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

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. |
