Permafrost and Environmental Conditions at Stream Crossing Sites in the Northern Mackenzie Corridor, Northwest Territories

Aboriginal Affairs and Northern Development Canada (AANDC) and the Geological Survey of Canada established ground temperature monitoring sites at three stream crossings along the northern Mackenzie Corridor in order to examine the impact of local environmental conditions on permafrost. Ground temperatures were measured between August of 2009 and August of 2010 at hilltop, north and south facing slopes and valley bottom sites. Water and ground temperatures beneath the stream were also measured to provide information on the thermal influence of tundra streams on permafrost. Surface layer measurements consisting of vegetation height, active layer thaw depth and snow depth were acquired along cross valley transects. In addition, ground penetrating radar surveys were conducted to determine winter stream conditions at each site. This dataset improves the characterization of permafrost and environmental conditions at stream crossing sites where significant geotechnical challenges exist and provides useful baseline information necessary for the planning, design and regulation of infrastructure along the potential development corridor.
