This paper describes gas composition, total gas content and bubbles characteristics in winter lake ice for four adjacent lakes in a discontinuous permafrost area. Our gas mixing ratios for O 2 , N 2 , CO 2 , and CH 4 suggest that gas exchange occurs between the bubbles and the water before entrapmen...
