I am interested in calculating the carbon system. I know that two of the four CO2 properties (ΣCO2, PCO2, pH,and carbonate alkalinity) can be used to determine the entire CO2 system, but I dont know the equations that can be used to relate a set of properties to the whole system. How can I use pH and ΣCO2 to calculate PCO2 and carbonate alkalinity? Or ΣCO2 and carbonate alkalinity to calculate the speciation of each carbon species?
