a08.dat (File 5)

This file provides hydrographic, carbon dioxide, and chemical data for all stations occupied during the R/V Meteor cruise along WOCE Section A8. Each line consists of a station number, cast number, sample number, bottle number, CTD pressure, CTD temperature, CTD salinity, potential temperature, bottle salinity, bottle oxygen, silicate, nitrate-plus-nitrite, CFC-11, CFC-12, TCO2, fCO2 @ equilibrator temperature, equilibrator temperature, fCO2 @ 20°C, calculated pCO2 @ 20°C, and data-quality flags. The file is sorted by station number and pressure and can be read by using the following FORTRAN 90 code [contained in a08dat.for (File 3)]:

bota - is the bottle number;

pre - is the CTD pressure (in dbar);

ctdtmp - is the CTD temperature (in °C);

ctdsala - is the CTD salinity [on the Practical Salinity Scale (PSS)];

theta - is the potential temperature (in °C);

sala - is the bottle salinity (on the PSS);

oxya - is the oxygen concentration (in µmol/kg);

silcaa - is the silicate concentration (in µmol/kg);

nitrata - is the nitrate plus nitrite concentration (in µmol/kg);

qualt - is a 9-digit character variable that contains data-quality flag codes for parameters underlined with asterisks (*******) in the file header.

----------------------------------------------
aVariables that are underlined with asterisks in the data file's header indicate they have a data-quality flag. Data-quality flags are defined as follows:

1 = Sample for this measurement was drawn from water bottle but analysis was not received;
2 = Acceptable measurement;
3 = Questionable measurement;
4 = Bad measurement;
5 = Not reported;
6 = Mean of replicate measurements;
7 = Manual chromatographic peak measurement;
8 = Irregular digital chromatographic peak integration;
9 = Sample not drawn for this measurement from this bottle.
