| Abstract | A major field program was undertaken in February and March 2007 by the Geological Survey of Canada in order to address gaps in baseline environmental information in the Mackenzie Valley, south of Norman
Wells, Northwest Territories. Sites were selected to represent a range of ground-thermal, terrain, and vegetation conditions. Drilling of boreholes to depths of 20 m yielded data for characterization of subsurface materials at 16 locations, including
physical properties of soil and ground-ice conditions. Twenty boreholes were preserved and instrumented with temperature cables and the data acquired has enabled a preliminary characterization of the ground-thermal regime. Key baseline information
was generated for a suite of representative terrain types that may be utilized in planning northern development and environmental impact assessment. Ongoing data collection from thermal monitoring sites will facilitate improved characterization of
current permafrost conditions and change detection. |
