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...

2013201220112010 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...

2012 Summary:
This is a multidisciplinary project involving communities, governments and academic researchers. The goals are to: 1) inventory and track broad scale changes in landscape disturbances; 2) determine the impacts of natural and anthropogenic disturbances on the physical and chemical characteristics and ecology of streams and rivers; 3) determine disturbance thresholds relevant to the health of stream...

2010 Summary:
In the Gwich’in Settlement Region, residents of Fort McPherson have identified the unusual size of the mega-slumps on the Peel Plateau as a serious concern to both water quality and aquatic ecosystem. In addition to research oriented objectives relevant to understanding cumulative effects of mega-slump development on the land and water of the Peel Plateau, the project team will pursue establishing...

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 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 ...
