The distribution of permafrost and its relation to air temperature in Canada and the U.S.S.R.
Permafrost is a widespread phenomenon in the northern parts of North America and Eurasia, and in Antarctica. Between 40 and 50 per cent of Canada's total land surface of 3.8 million square miles is underlain by permafrost. The total land area of the U.S.S.R. exceeds 8 million square miles of wh...

| Summary: | Permafrost is a widespread phenomenon in the northern parts of North America and Eurasia, and in Antarctica. Between 40 and 50 per cent of Canada's total land surface of 3.8 million square miles is underlain by permafrost. The total land area of the U.S.S.R. exceeds 8 million square miles of which 47 per cent is underlain by permafrost (Tsytovich 1958). Because of the great extent of this phenomenon knowledge of its distribution is of vital concern to both countries. Le pergélisol est un phénomène géologique répandu dans les régions boréales de l'Amérique du Nord et de l'Eurasie, ainsi qu'en Antarctique. Le sous-sol de 40 à 50 p. 100 des terres émergées du Canada, totalisant près de 11 000 000 km2 (3 800 000 mi2) est constitué de pergélisol. C'est également sur ce type de sous-sol que repose 47 p. 100 des quelque 23 200 000 km2 (8 000 000 mi2) de superficie terrestre totale de l'U.R.S.S. (Tsytovich, 1958). En raison de la grande étendue de ce phénomène, il demeure vital pour l'un et l'autre pays d'en bien connaître la distribution. Peer reviewed: Yes NRC publication: Yes |
