AbstractGround 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.
Summary(Plain Language Summary, not published)
In July 2013, eight boreholes on the Alaska Highway easement between Haines Junction and the Alaska border were instrumented to measure ground temperatures to improve characterization of permafrost conditions. This information is required for terrain sensitivity assessments and planning northern development (eg. pipeline, highway) to ensure infrastructure and environmental integrity. Data collected, in collaboration with the Yukon Research Centre, in summer 2014 provided a one-year record of ground temperatures. Although permafrost in this section of the corridor is generally warmer than -1°C, permafrost as cold as -3°C was found near the Alaska border.
