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 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)

Stated in tabular form, the contents include the following:

Variable Variable type Variable width Starting column Ending column
lon Numeric 7 1 8
lat Numeric 6 9 16
dep Numeric 7 16 25
mld Numeric 7 24 34
talk Numeric 9 32 43
tmp Numeric 7 42 52
sal Numeric 7 50 61
coefa Numeric 10 58 70
coefb Numeric 10 69 79
coefc Numeric 10 80 88

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.
