AbstractMineral exploration in Northern Manitoba and District of Keewatin and investigations for a proposed natural gas pipeline have produced a need for permafrost information where virtually no data were previously available. Thermocouple and thermistor cables have been installed at various depths down to 15 m in different types of terrain in this region. Ground temperatures recorded during 1974-1976 inclusive and their relation to climatic and terrain factors are presented. Annual variations in ground temperatures and thickness of the active layer in response to annual fluctuations of summer and winter air temperatures indicate the influence of climate on permafrost. Ground temperatures vary in different types of terrain at one location due to variations in vegetation, snow cover, proximity to water bodies, and type of soil and rock.
