Objective(s): To measure regional and site variability in maximum active layer development and vertical surface movement over permafrost. To monitor sites over time in order to observe trends, perhaps resulting from climatic change.

Project Description: For this ongoing study, measurements such as maximum depth of thaw and soil surface movements, recorded after previous visit, will be collected. Monitoring apparatus will be reset this season. Sites in the Mackenzie Delta, from Tsiigehtchic (Arctic Red River) to Tuktoyaktuk will be visited in mid-April. Most sites from Fort Simpson to Tuktoyaktuk will be visited during late July, early August.
