Summary: This project continues the on-going monitoring program of permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT. This phase of the project is largely data collection. The specific objectives are: 1) to provide baseline knowledge of permafrost and terrain conditions (specifically ground temperature and permafrost active layer thickness) and ...

Summary: The objective of this study is to determine the effect of fire on water quality within the southern NWT landscape. The research team will work across the Taiga Plains and Taiga Shield ecoregions. Differences in landscape between these regions will affect the catchment response to fire. The team will also target catchments with variable permafrost extent, and wetland/lake coverage. The research ...

Summary: The project team intend to study carbon cycling in peatland catchments, in order to determine whether the interactions between wildfire and permafrost thaw causes increased release of greenhouse gases from peatlands and aquatic ecosystems to the atmosphere, and thus cause amplified climate change. Given the overall objective of the project, the team intend to address five research questions: ...

Summary: The goal of this project is to look at how permafrost is changing following forest fire over a range of environmental conditions, with the purpose of improving how change is modeled in the future. The fires of 2014 in the southwestern Northwest Territories (NWT) provide an opportunity to examine how discontinuous permafrost responds to disturbances. This work is being carried out in collaboration ...

Principal Investigator: Turetsky, Merritt R.
Licensed Year(s): 2011
Summary: The goal of this research project is to measure the concentration and composition of natural dissolved organic carbon in rivers along a latitudinal transect from central Alberta to southern NWT. Data on water quality will be combined with spatial data that describes the drainage basins of the sampled rivers, e.g. ecosystem composition, size, slope, recent fire impact and permafrost conditions. The...

Summary: The Geological Survey of Canada maintains a network of active layer and permafrost temperature monitoring sites in the Mackenzie region in order to document the response of permafrost conditions to climate change. Gaps exist in the network in the permafrost zones north of Norman Wells, the Mackenzie Delta region, and on shorelines and coastlines. Enhancement of the network is essential to provide ...

Principal Investigator: Menounos, Brian p
Licensed Year(s): 2006
Summary: The various objectives of the study are: to refine the previously compiled landslide inventory map with field checking, to identify causal mechanisms to slope instability (such as bedrock or surficial material type, aspect, elevation, glacial history, and permafrost distribution), to identify frequency of landslide types, to examine landscape patterns in the Nahanni karst area to establish relatio...

Summary: The active layer, overlying the permafrost layer, is the surface earth material that thaws and re-freezes each year. Active layer thickness and character can influence hunting, fishing, forestry, gardening, transportation and construction. Changes in the active layer can contribute to landslides which may damage structures, hamper transportation, affect water quality, and influence surface and sub...
