Abstract

Thermodynamic considerations have been applied to data showing that the solubilities of oxygen, carbon dioxide, and helium in water decrease with increasing pressure and depth. When water is saturated with a given gas at 1 atmosphere absolute, the equilibrium partial pressure of the gas at any depth is equal to the partial pressure of that gas if it were contained in a gas column extending from the surface to that particular depth.
