Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No. 5820. The proposed project will evaluate the temporal and spatial distribution of Polybrominated Diphenyl Ethers (PBDE) in the water and sediment of Great Slave Lake and surrounding communities, landfills, drinking water, and industries to identify the source of PBDEs. The concentration and distribution of PBDEs will b...

Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5463. The objectives of this project are to develop improved understanding of, and ability to predict, snowcover properties from numerical models used to simulate climate and hydrology in northern regions; to consider the integrated effect of climate on vegetation, snow, permafrost, and lakes; and, to develop improved predi...

Principal Investigator: Tank, Suzanne E
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5138. The objectives of this study are to determine the influence of permafrost thaw on the mobilization of carbon to stream ecosystems, and its subsequent effects on in-stream microbial communities and carbon cycling. The research team will measure stream water chemistry and collect water samples for microbial analysis at ...

Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.4703. The objective is to improve the quantitative understanding of carbon dynamics in Canadian subarctic freshwaters, with a focus on identifying the processes governing the balance between carbon sinks and carbon sources to the atmosphere. The research team will pair field-based observations with laboratory experiments...

Summary: It is the objective of this research to determine the water cycle processes acting in watersheds that could affect the streamflow response and water chemistry of Taiga Shield streams. The proposed work will take place within a research basin framework. The proposed watershed, the upper reaches of Baker Creek, is a typical Canadian Shield stream that drains 150 km2 into Great Slave Lake. There ...

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: Grasby, Stephen
Licensed Year(s): 2005 2004
Summary: Historic mention is made of springs at Windy Point on the north shore of Great Slave Lake. The research team is interested in confirming if these springs are still present and to establish the origin and chemistry of the water. The research team will sea...

Licensed Year(s): 2003 2002 2001 2000
Summary: The objectives of the research are to examine how changes in active layer depth influence groundwater and surface water chemistry in two subbasins of the Daring Lake basin in the headwaters of the Coppermine River Basin. In addition, a snow survey of th...

Principal Investigator: Chapman, Peter M.
Licensed Year(s): 1996
Summary: The Lupin study site is one of seven mine sites being investigated across Canada. Receiving water samples will be collected for chemistry (total and dissolved metals) and toxicity testing. To ensure that a well-defined chemical gradient exists water and sediment will be collected from reference and exposure stations at the study site. Sediment samples will be collected for chemistry (total orga...
