Summary: This licence has been issued for the scientific research application No.4985. The objectives of this project are to investigate impacts of permafrost slumping on water quality, benthic macroinvertebrate communities, fish communities and ecosystem function by (a) advancing research on previously studied thaw slumps within the Stony Creek Watershed and include unstudied (for biotic metrics) thaw ...

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: Climate change and industrial contaminants are two principal concerns for Arctic residents. The objectives of this research are to examine the impacts of climate and environmental change on freshwater ecosystems in the Inuvik region across a variety of spatial and temporal scales. Specifically, the team is examining the impacts of permafrost degradation and subsequent thaw slumping on freshwater e...

Summary: The overall objective of the Lake 5A mesocosm study is to better understand the impact of permafrost thaw shoreline slumping (an analogue for a warming climate) on the bottom components of the aquatic food-web in small Arctic tundra lakes in order to better predict the effects of a warming climate on food-web structure, function and productivity. To assess the direct and indirect effects of per...

Summary: The objective of this field work is to better understand the movement behaviour of the landslides in the region. The Geological Survey of Canada’s research group lead by Dr. Baolin Wang has been conducting landslide research in the region since 2004. This is the final year of the project. The previous permits have expired. However, there is a need to make a follow up trip to the various landsli...

Summary: This study investigates the distribution and amount of near-surface ground ice in sediments of the Mackenzie Delta area. The research team will consist of Steve Kokelj (Carleton University - principle researcher) and Doug Joe (Inuvik). The proposed fieldwork will begin in Inuvik in April, with the main part of the field work being carried out from 30 July to 20 August. In April, the research te...

Summary: This is a study of retrogressive thaw sumps produced by the exposure and melting of massive ice in continuous permafrost (Richardson Range, NWT). These sumps are recently occurring and presumably a result of global climate change. This research will recognize retrogressive thaw slumps that have massive ice, identify the type of massive ice (glacier buried or segregated) and measure the rate of ...

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....

Summary: To determine the maximum size of treeline tree species in a burned and unburned valley in the Caribou Hills, the mass of standing trees on different slopes and aspects will be estimated and related to the energy input. In 1992 the plots prepared in 1990 and planted and seeded in 1991, will be revisited and measurement of growth for the second growing season will be taken....
