Basic programs for the CO{sub 2} system in seawater
The CO{sub 2} system in seawater is characterized by four measurable parameters: TA, the total alkalinity; TC, the total (inorganic) CO{sub 2} (the sum of the dissolved CO{sub 2}, the carbonate, and the bicarbonate); pH; and either fCO{sub 2}, the fugacity of CO{sub 2}, or xCO{sub 2}, the mole fraction of CO{sub 2} in air. Ta and TC are independent of temperature; fCO{sub 2}, xCO{sub 2}, and pH are not. The knowledge of any two of these parameters, along with the temperature, the salinity, the abundances of other constituents of seawater, and the relevant equilibrium constants, allows the determination of the other two. There are four programs in this package: CO2SYSTM.EXE; FCO2TCO2.EXE; PHTCO2.EXE; CO2BTCH.EXE. They are designed to be run on any 80 x 86 computer equipped with the DOS operating system. They are run simply by typing the program name from the command line. All input data for these programs should be in micromoles per kilogram of solution ({micro}mol/kg-soln), micro-atmospheres ({micro}atm) in the case of fCO{sub 2}, and parts per million (ppm) in the case of xCO{sub 2}. The pH should be on the total scale. All outputs are in these units also. Each program in this package allows a choice from the four sets of constants K{sub 1} and K{sub 2}: those of Roy et al., Goyet and Poisson, Hansson and Mehrbach et al.
