AbstractA major fi eld program was undertaken in March 2007 by the Geological Survey of Canada in order to address gaps in baseline environmental information in the Mackenzie Valley between Fort Good Hope and Norman Wells, Northwest Territories. Sites were selected to represent a range of groundthermal, terrain, and vegetation conditions. Eleven boreholes were preserved and instrumented with temperature cables to provide information on the ground-thermal regime. Data collected from ten of these boreholes in September 2007 allow a preliminary characterization of the ground-thermal regime in an area where little recent data are available. Key baseline ground-thermal information was generated for a suite of representative terrain types that may be utilized in planning northern development and environmental impact assessment. Ongoing collection of data from the thermal-monitoring sites will continue to facilitate improved characterization of current permafrost conditions and change detection.
