description |
Colour Lake, Axel Heiberg Island, NWT (79°25′N; 90°45′W), remained largely ice covered from autumn 1985 to summer 1987. This is a relatively rare event. Observations and measurements of the thickness and specific conductance of the lake ice cover were made at the end of 1986 summer and again in the following spring. The residual ice cover (second-year ice with first-year ice beneath it) was significantly thicker and had a lower specific conductance than first-year ice formed in marginal leads (moat) that had been ice free in 1986. The first-year ice that grew beneath the residual ice cover had the lowest specific conductance. Distribution of snow on the lake was affected by the roughness of the second-year ice (as compared to the smoother moat ice) and differences in elevation between second-year (high) and moat ice. -Authors |
