Summary: | Making use of limited ground temperature measurements in the neighbourhood of a small shallow lake near Inuvik, N.W.T., it was possible with the help of a electronic computer to estimate the entire thermal regime under and about the lake. The results indicated a completely unfrozen zone of roughly hour-glass shape directly under the lake. Field borings under the lake and adjacent to it supported this theoretical finding. En partant de quelques observations faites sur la tempé rature du sol dans les environs d'un petit lac peu profond près de Inuvik, Territoire du Nord-Ouest, il a été possible, au moyen d'un calculateur électronique, de faire une estimation du régime thermique complet existant sous le lac et dans ses environs. Les résultats ont montré qu'il existait directement sous le lac une zone complètement dégelé e ayant approximativement la forme d'un sablier. Des sondages effectués sous le lac et tout près de lui ont corroboré ce résultat théorique. Peer reviewed: Yes NRC publication: Yes |
