uwpco2.dat (File 7)

This file contains underway pCO₂ measurements taken along the cruise track during the R/V Meteor Cruise 18/1. Each line of the file contains a sampling date; sampling time; latitude; longitude; and measurements of sea surface salinity, temperature, and pCO₂. The file is sorted by date and time and can be read by using the following FORTRAN 77 code [contained in uwpco2dat.for (File 4)]:

            
            INTEGER day, month, year 
            CHARACTER time*5
            REAL latdcm, londcm, salt, temp, pco2
            OPEN (unit=1, file='uwpco2.dat')
            OPEN (unit=2, file='uwpco2.data')
            write (2, 5)
        
            read (1, 10, end=999) day, month, year, time, latdcm, 
          1 londcm, salt, temp, pco2
     
      10    format (I2, 2X, I1, 2X, I4, 2X, A5, 3X, F6.3, 3X, F7.3, 3X, 
          1 F7.4, 2X, F5.2, 2X, F5.1)

Stated in tabular form, the contents include the following:

Variable	Variable type	Variable width	Starting column	Ending column
day	Numeric	2	1	2
month	Numeric	1	5	5
year	Numeric	4	8	11
time	Character	5	14	18

londcm	Numeric	7	31	37
salt	Numeric	7	41	47
temp	Numeric	5	50	54
pco2	Numeric	5	57	61

where

day	-	is the sampling day;
month	-	is the sampling month;
year	-	is the sampling year;
time	-	is the sampling time (GMT);
latdcm	-	is the latitude of the station (in decimal degrees; negative values indicate the Southern Hemisphere);
londcm	-	is the longitude of the station (in decimal degrees; negative values indicate the Western Hemisphere);
salt	-	is the sea surface salinity;
temp	-	is the sea surface temperature (^oC);
pco2	-	is the sea surface pCO₂ (µ atm).
