(Sharon Lee) Ground thermal data collection along the Alaska Highway easement (KP 1559-1895) Yukon, summer 2014 [electronic resource] / [by] S.L. Smith and M. Ednie. Ottawa : Natural Resources Canada, 2015. ii, 22 p. : figures, tables, graphs, map. Open file (Geological Survey of Canada) ; 7762 Includes bibliographic references. Ground temperature data were acquired in summer 2014 from eight boreholes instrumented in summer 2013 along the Alaska Highway easement between KP1559 and the Alaska border. Permafrost was found to be present at six boreholes and was generally at temperatures above -0.7°C except near the Alaska border where permafrost temperature was -3°C. Summer thaw depths at permafrost sites range from 0.8 to 2.4 m. A warm period in January 2014, during which air temperatures rose above 0°C, appears to have had an impact on shallow winter ground temperatures at most sites. The information provided contributes to the characterization of regional permafrost conditions and supports decisions regarding development projects in the region, climate change assessments and adaptation planning. gccst Permafrost gccst Surficial geology gccst Geomorphology Ednie, Mark, 1977- Canada.
