PRESS is the pressure in units of decibar (dbar).
DEPTH in meters.
Temperature in Degrees Celcius.
Salinity in units of PSU (Practical Salinity Units).
PO4, NO3, NO2, SiO3, AOU, and Oxygen in units of micromoles per kilogram seawater.
AOU is apparent oxygen utilization. Units of micromoles per kilogram seawater.
Total CO2 in units of micromoles per kilogram seawater.
pCO2 units are microatmospheres, and are reported at the Temperature
designated by PCO2_TEMP. pCO2 was measured at this temperature.
Total Alkalinity (TALK) are computed values, expressed in units of
microEquivalents per kilogram seawater.
THETA is the potential temperature at pressure of zero dbar.
SIGMA0, SIGMA2, SIGMA4 are potential density in "sigma units",
at zero, 2000, and 4000 dbar pressure, respectively.
Delta C-14 units are parts per thousand. (Capital Delta).
Natural C-14 data were estimated by Wally Broecker.
Bomb C-14 data were estimated by Wally Broecker.
Delta C-13 units are parts per thousand.
Tritium reported in units of "Tritium Units" at the
time the measurement was taken, or for GEOSECS 1/1/74.
Blank values indicated by -999.9.
