Partial Pressure of CO2 in Water provides a measure of the amount of CO2 and HOC3 in seawater. Specifically, it refers to the pressure that would be exerted by CO2 if all other gases were removed. Partial pressure of a gas dissolved in seawater is understood as the partial pressure in air that the gas would exert in a hypothetical air volume in equilibrium with that seawater.
