List of variables included in this dataset:

COLUMN	HEADER			EXPLANATION
1.  GROUP/SHIP:         AOML_Brown for all underway data from the Ron Brown.
2.  CRUISE_DESIGNATION: Cruise ID (e.g., RBYYYYnn where RB = Ron Brown, YYYY
                        = the four digit year, and nn = the cruise number for that year).
3.  JD_GMT:             Decimal year day.
4.  DATE_DDMMYYYY:      GMT date.  The date format has been changed to comply with the IOCCP recommendations.
5.  TIME_HH:MM:SS:      GMT time.
6.  LAT_DEC_DEGREE:     Latitude in decimal degrees (negative values are in the southern hemisphere).
7.  LONG_DEC_DEGREE:    Longitude in decimal degrees (negative values are in the western hemisphere).
8.  xCO2W_PPM:          Mole fraction of CO2 (dry) in the equilibrator headspace at equilibrator temperature (Teq) 
                        in parts per million.
9.  xCO2A_PPM:          Mole fraction of CO2 in air in parts per million.
10. EqTEMP_C:           Temperature in equilibrator water in degrees centigade. Temperature in equilibrator 
                        measured with a calibrated thermistor.
11. PRES_EQUIL_hPa:     Barometric pressure in the lab in hectopascals (1 hectopascal = 1 millibar).
12. SST(TSG)_C:         Temperature from the ship's thermosalinograph in degrees centigrade.
13. SAL(TSG)_PERMIL:    Salinity from the ship's thermosalinograph on the Practical Salinity Scale.
14. fCO2w,eq:           Fugacity of CO2 in the equilibrator in microatmospheres calculated as outlined below.
15. fCO2W@SST_uatm:     Fugacity of CO2 in sea water in microatmospheres calculated as outlined below.
16. fCO2A_uATM:         Fugacity of CO2 in air in microatmospheres calculated as outlined below.
17. dfCO2_uatm:         Sea water fCO2 - air fCO2 in microatmospheres. This uses the average air value for the current hour.
