AbstractCased boreholes along the Alaska Highway easement in the southern Yukon were acquired from TransCanada Pipelines Ltd. by the Geological Survey of Canada. Eight of the boreholes between KP1559 (near Haines Junction) and the Alaska border were instrumented for ground temperature measurement in July 2013 to provide improved information on current permafrost conditions in the highway corridor. The initial data acquired shortly after installation of thermistor cables, indicates that ground temperatures are generally higher than -1°C except at one site near the Alaska border where ground temperature is about -3°C. The instrumented sites will be maintained in collaboration with the Yukon Research Centre, Yukon Department of Highways and Public Works and the Yukon Geological Survey. Continuous data collection for at least one year will facilitate characterization of ground thermal conditions in this portion of the corridor and provide updated information to support infrastructure design and decisions regarding development projects in the region.
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. Collaboration with TransCanada pipelines, Yukon Highways and Public Works, Yukon Research Centre and Yukon Geological Survey facilitated site establishment. Initial ground temperature data collected in July 2013 indicates that permafrost is generally warmer than -1°C but is as cold as -3°C near the Alaska border.
