Abstract
Permafrost Studies in the Norman Wells Region, Northwest Territories
Abstract
The mean annual temperature of the surface of the Canol Road, built during the Second World War, is significantly higher than that of the ground surface prior to construction. A study of the roadway and its surroundings by drilling and by seismic and electric methods confirms that there has been warming and, in some cases, thawing of permafrost under the road. A geothermal model prepared for one of the sites predicted a depth of thaw much smaller than the depth shown by the drilling. This result suggests that both convection and conduction may be involved in heat-transfer processes under the road.
