Abstract
In the area surrounding Eureka, Northwest Territories, ground ice accounts for a significant fraction of surficial material, comprising 30.8% of the upper 5.9 m of permafrost. Volume depends on the type of ice examined, ranging from 1.8 to 69.0% in different regions of the study area. Excess ice accounts for 1.3% of frozen materials. In areas underlain by massive ice, 16.2% of the permafrost is considered to be excess ice. Data is drawn from ground measurements and a number of secondary sources, including air photographs, maps, and previous studies which examined specific occurrences of ground ice in the Eureka area. The importance of quantifying the volume of ground ice in this area is discussed, especially in light of how a warming climate and anthropogenic activities in the area can alter the landscape.
