Summary: The objective of this study is to understand how permafrost slumping increases the mobilization of organic carbon from land to water, and the effects of this movement on stream communities. The research team will measure the concentration of stream-water organic carbon upstream and downstream of slump sites. The research team will also examine the fate of this carbon by undertaking incubation expe...

Summary: Thaw slumps are one of the most dramatic thermokarst features in permafrost regions. The number of thaw slumps on Banks Island has more than tripled in recent decades and it is likely that this change is altering terrestrial and aquatic ecosystems. This multidisciplinary research project investigates the short- (1960s-present day) and long-term (Medieval Warm Period to today) impacts of permafrost...

Summary: The objective of this research project is to document the extent of ecological change in impacted stream basins draining the eastern slope of the Richardson Mountains and to determine the mechanisms of slump initiation and stabilization. This study will focus on the Stoney Creek catchment, which runs parallel to the Dempster Highway and empties into the Peel River at Fort McPherson, NT. The catchm...

Summary: This licence is being issued for the scientific research application no. 978. The objectives of this research are to: 1) Monitor permafrost conditions in the Mackenzie Delta region; 2) examine freeze-back of the active layer and associated strength properties of freezing soil; 3) examine the influence of shrub removal on frozen ground and snow conditions at abandoned drilling-mud sumps; 4) inve...

Summary: For this on-going study, measurements such as maximum depth of thaw and soil surface movements recorded after the previous visit, will be collected. Monitoring apparatus will be reset this season. Sites in the Mackenzie Delta, from Tsiigehtchic to Tuktoyaktuk will be visited in April. Most sites from Fort Simpson to Tuktoyaktuk will be occupied during the summer....
