Permafrost zonation in eastern Canada : a review of published maps

Auteur :
NELSON, F. E.

Description :
Although progressive improvements in data availability are apparent through time, many of the differences between maps are attributable to a lack of explicit mapping criteria, to ambiguous or conflicting definitions of permafrost continuity and to the widely recognized lack of observational data. The term continuous permafrost should be used only with reference to small (e.g., subcontinental) geographic scales, in which zonal tendencies are apparent.
