Implication

Experimental study reveals carbon dioxide permeates ice via intercrystalline brine films while oxygen does not, indicating gas transport depends on liquid pathways.

Key Points

To measure the permeation rates of carbon dioxide and oxygen through ice at different temperatures and determine their mechanism of transport.
Measured the permeation rates of carbon dioxide and oxygen through ice specimens across several temperatures up to 0°C.
Carbon dioxide exhibited a permeation constant of 0.7 × 10⁻¹¹ cm² sec⁻¹ atm⁻¹ at −9.5°C (approximately two million times lower than in liquid water), increasing hyperbolically toward 0°C.
Oxygen permeation through ice was below the limit of detection under the experimental conditions.
Gas transport through ice occurs via intercrystalline brine films along crystal boundaries rather than diffusion through the ice crystal lattice.
