Abstract
Permafrost, or perennially frozen ground, occurs everywhere beneath the land surface of Truelove Lowland, which is situated in the northern part of the continous zone. The presence of thick continuous permafrost throughout the Canadian Arctic Archipelago has been known for a long time, but until recently investigations have been limited to a few scattered locations. During the past few years, observations have increased considerably, especially in the Queen Elizabeth Islands, with the onset of petroleum explorations. The Canadian Tundra Biome Study of the I.B.P. provided an opportunity to obtain information on permafrost conditions in the major terrain types at Truelove Lowland. No permafrost investigations had been carried out previously on Devon Island. A preliminary indication of permafrost conditions was available from observations at Resolute, N.W. T., 320 km to the southwest on adjacent Cornwallis Island. At this location permafrost was found to be about 400 m thick with a temperature of -12.5 degrees C at the depth of zero annual amplitude.
