Abstract
Permafrost investigations on Truelove Lowland. Detailed discussion of surface features characteristic of high latitude permafrost. Soil and rock profiles, ground temperature and snow cover measurements are taken at thermocouple cable sites, thickness of the active layer and depth of thaw, and correlations in the relationship between permafrost and environmental factors are also studied. Judge, A.S. Calculations of permafrost thickness. Permafrost thickness at Truelove Lowland may be as thin as 210 m in coastal areas (Limestone-Coast Site) and as thick as 659 m on the adjacent upland (Upland Plateau Site). The presence of a nearby relatively warm sea has a highly modifying influence on coastal areas increasing the subsurface temperature at the Limestone-Coast Site by 6 deg. C at a depth of 90 to 170 m.
