[ECOLOG-L] Help on Conversion of CO2 Conc. to pCO2 in lake water

[Nicola Mcenroe]

Hey Ecologers:

I have calculated concentration of CO2 in mg/cubic meter of boreal lakes 
water. I am interested to convert the concentration of CO2 in lake water 
to its pCO2 (partial pressure) values. I have the lake water temperature 
and pH data. Can you help me in how to calculate the pCO2 values?

Thanks in anticipation
