These files provide the interpolated TALK fields calculated annually and for each quarter (talk_ann.dat, talk_djf.dat, talk_mam.dat, talk_jja.dat, and talk_son.dat). The files are sorted by longitude and latitude and can be read by using the following FORTRAN 77 code [contained in talkdat.for (File 5)]:
Stated in tabular form, the contents include the following:REAL lon, lat, dep, mld, talk, tmp, sal, coefa, coefb REAL coefc read (1, 10, end=999) lon, lat, dep, mld, talk, tmp, 1 sal, coefa, coefb, coefc 10 format (F7.1, 1X, F6.1, 1X, F7.1, 1X, F7.1, 1X, F9.1, 1 1X, F7.3, 1X, F7.3, 1X, F10.3, 1X, F10.3, 1X, F10.3)

The variables are defined as follows:
lon - is the longitude for which TALK was calculated;
lat - is the latitude for which TALK was calculated;
dep - is the depth for which TALK was calculated (m);
mld - is the maximum layer depth (m);
talk - is the total alkalinity (µmol/kg);
tmp - is the temperature (°C);
sal - is the salinity;
coefa - is the a coefficient (offset);
coefb - is the b coefficient to temperature; and
coefc - is the c coefficient to salinity.
