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.
