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 ...

Summary: The objectives are to work with local residents of Wekweeti to understand how changes in the annual snowpack may impact caribou. The idea is that with increased incursions of warm southern air into the subarctic during winter that snow crusts and ice lenses may be created in the snowpack and as a result increase the energy expenditures of the caribou when foraging for food at the base of the snowp...

Summary: This project will focus on providing baseline information for areas of high resource potential. In areas of past land use and soon to be developed areas in the Slave Geological Province, the project will generate new spatial and temporal data on changing geochemical, permafrost, ecological and climate data for the past 1000 years. This data will be integrated with Traditional Ecological Knowledge ...

Summary: The objectives of this research project are: 1) to determine the impact of shoreline expansion and forest/peat submergence from thawing permafrost on contaminant and carbon fluxes to lakes in the Yellowknife region; 2) to develop novel approaches to track terrestrial organic matter sources in lakes, in order to assess how climate warming and permafrost thaw are affecting the delivery of terrestr...

Licensed Year(s): 2009
Summary: This licence is issued for the scientific research application #932. The goal of this multi-disciplinary paleolimnological study will be employed to describe and further understand regional climate conditions, fire history, and ice cover duration spanning the past ~2000 years in the central Northwest Territories. The targeted study area is the southern portion of the Tibbitt to Contwoyto Winte...

Licensed Year(s): 2008
Summary: This licence is issued for the scientific research application # 876. The objective of this research is to determine the impacts of predicted soil warming scenarios for the arctic on the availability of phosphate, nitrate-nitrogen and ammonium, which are important soil nutrients. The field portion of this research will consist of two weeks of collecting soil data and gauging and sampling (f...

Principal Investigator: Coxson, Darwyn S
Licensed Year(s): 2008 2007
Summary: The objective of this research is to study how northern soils in close proximity (geospatially linked soils) cycle nitrogen and carbon and produce greenhouse gases. Describing these links will allow forecasting on how the soils respond to climate change. Three transects with 31 sampling locations will be set up. At each location a Time Domain Reflectometry (TDR) probe and thermocouple will be i...

Licensed Year(s): 2005 2004 2003
Summary: The objective of this project is to determine the effect of Great Slave Lake on air and surface temperatures, and permafrost conditions. Each of the study sites along the Ingram Trail that were instrumented with air and surface temperature sensors during summer 2003 will be revisited in 2005. The data loggers will be downloaded, relaunched and the batteries will be replaced at each instrumentati...

Principal Investigator: Rouse, Wayne R
Licensed Year(s): 2001
Summary: The field work associated with the proposed study will consist of the collection of climate data, such as air temperature, humidity, wind speed, wind direction, amount of rain fall, water temperatures and light penetration into the lake. Similar equipment will be used to collect this data at all sites. Air temperature, humidity, wind speed, wind direction, water temperatures and light penetration...

Summary: The Mackenzie Basin Impact Study will assess the potential impacts of global climatic change on the region. The component on land assessment will determine possible changes in land capability. Information on resource management goals is needed so that the study can can assess whether changes in land capability might lead to conflicts over land use....
