talk_*.dat (Files 10-14)

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)]:

            
            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

         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.
