Principal Investigator: Bourdages, Madelaine
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5224. The first objective of this project is to quantify microplastic concentration and composition in water, sediment, zooplankton, and air around Great Slave Lake. The second objective of this project is to examine if microplastic concentrations are greater near communities than the open water of Great Slave Lake. The thi...

Summary: This licence has been issued for the scientific research application No.4623. The overall objective of this study is improved understanding of heavy metals in Sewage Disposal Facilities (SDFs) and Solid Waste Disposal Facilities (SWDFs) in the NWT. The proposed study aims to answer the following questions: 1) What is the existing treatment capacity of SDFs in NWT for heavy metals?; 2) Are SDFs ...

Summary: The goals of this research are to ascertain the formation of marine pockmarks, which are circular depressions on the sea floor thought to have formed from the release of methane gas. The hypothesis is that these features are actively releasing gas to the atmosphere and that they are formed from degrading or thawing offshore permafrost. The research team intend to document the seabed characteris...

Summary: The primary objective is to provide the means to improve the knowledge of physical conditions in the Arctic coastal zone in order to help government agencies, corporations and local residents understand mitigate and reduce the impacts of climate driven changes. This research has 3 targeted objectives: 1) to gain a better understanding of coastal permafrost; 2) to provide and updated assessment of ...

Principal Investigator: Normandeau, Philippe X.
Licensed Year(s): 2017
Summary: The research team will investigate sections of exposed sediments along the Redstone River banks and some minor tributaries to establish the provenance and composition of these sediments. The team will evaluate the possible presence of ancient preglacial sediments buried beneath glacial sediments. It is also believed that ancient lake sediment may be present outside of the present flood plains of t...

Principal Investigator: Blais, Jules M
Licensed Year(s): 2017 2016 2015
Summary: The research team propose to develop tools to assess risks associated with legacy industrial developments in a northern setting. The team will investigate contaminants from the Giant Mine near Yellowknife Northwest Territories (NT), which operated between 1948 and 2004, producing a legacy of contaminants including arsenic, antimony, hydrocarbons, mercury, and others. This remediation strategy appl...

Licensed Year(s): 2015 2014
Summary: Industry and regulators require information on seismicity and its effect on engineering structures both at a regional and local scale. The primary source of this information is the National Building Code of Canada’s Seismic Hazard Value map. Ongoing work undertaken as part of the 2015 revision of this map suggests that an increased seismic (earthquake) hazard exists in the Mackenzie-Beaufort area....

Principal Investigator: Doucet, Michael
Licensed Year(s): 2016 2015
Summary: The objective of this program is to determine the environmental and physical conditions at nine sites on Gordon Lake and potentially six Gordon Lake south sites. This will include the identification and quantification of environmental impacts in soil, sediment, surface water and groundwater, and the identification of any hazardous or non-hazardous materials. In addition, samples of biota (includin...

Principal Investigator: Blais, Jules M
Licensed Year(s): 2014
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...

Principal Investigator: Nash, Tyler J
Licensed Year(s): 2012
Summary: The objective of this research project is to assess the sediment quality of Baker Creek. This will be achieved by analyzing factors influencing arsenic mobility from sediments to overlying water and assessing the toxicology of the sediments using exposure tests on indicator organisms. Core samples of Baker Creek sediments will be taken by the researchers using aluminum pipes driven into the gro...
