Abstract
The permeation rate of carbon dioxide and oxygen through ice has been determined at several temperatures. At −9.5° C the carbon dioxide permeation constant was found to be 0.7 times 10−11 cm2 sec−1 atm−1, which is about two million times less than in water. The permeation increased hyperbolically towards 0°C. No permeation of oxygen through the ice could be detected. It is concluded that the gas penetrates the ice through intercrystalline brine films rather than through the ice crystals.
