a10dat.txt (File 6)

This file provides hydrographic, carbon dioxide, and chemical data for the 112 stations occupied during R/V Meteor Cruise 22/5. Each line consists of a station number, cast number, bottle number, CTD pressure, CTD temperature, CTD salinity, potential temperature, bottle salinity, oxygen, silicate, phosphate, nitrate plus nitrite, CFC-11, CFC-12, total CO2, SOMMA number, total alkalinity, and data-quality flags. The file is sorted by station number and pressure and can be read by using the following FORTRAN 77 code [contained in a10dat.for (File 3)]:

The variables defined as follows:

sta - is the station number;

cast - is the cast number;

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);

phsphta - is the phosphate concentration (in µmol/kg);

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

cfc11a - is the trichlorofluoromethane-11 concentration (CCl3F) (in pmol/kg);

cfc12a - is the dichlorodifluoromethane-12 concentration (CCl2F2) (in pmol/kg);

tcarba - is the total carbon dioxide concentration (in µmol/kg);

som - is the SOMMA number;

talka - is the total alkalinity concentration (in µmol/kg);

qualt - is a 11-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.
