Further Examination of the Bio- Magnification of Mercury within Fish Species and watersheds of the Deh Cho and Their Varying Levels Among Lakes
Principal Investigator: Low, Mike
Licensed Year(s): 2023 2021 2019
Summary: This licence has been issued for the scientific research application No.5348. The objectives of this research project are: 1) to determine why fish mercury levels vary among lakes in the Dehcho region; 2) to identify best predictors of fish mercury levels; 3) to determine with fish have the lowest levels of mercury and the highest levels of nutrients; and, 4) to collect data on parameters that ...


Yellowknife Wetland Delineation Study and Great Slave Lake Monitoring
Principal Investigator: Brown, Jennifer M
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5336. The purpose of the Wetland Delineation Study is to define the flow paths of effluent from the treatment lagoon to Great Slave Lake and thereby inform sampling design of the Great Slave Lake Monitoring Program. The objectives of the Wetland Delineation are varied and, based on available documentation, we understand the...


Investigating the seasonality of subarctic lakes in a changing climate using satellite & field data
Principal Investigator: Kheyrollah Pour, Homa
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5335. This proposed research is directed at understanding the impact of current/future climate warming on subarctic lake ecosystems. The aim is to explore the relationship of seasonal lake ice growth/ablation and water quality across a wide range of lake characteristics (size, volume, productivity, catchment characteristics...


Biogeochemistry of Lakes in the Mackenzie Delta
Principal Investigator: Lesack, Lance
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5320. The objectives of this project are to improve the understanding of methane cycling in Mackenzie Delta lakes and how it is affected by the changing water levels and to decipher the impact of water level changes on the ability of the Mackenzie Delta to affect riverine carbon and nutrient flow to the ocean. Improve un...


Monitoring cumulative effects to water quality: An NWT Pilot Study
Principal Investigator: Chin, Krista
Licensed Year(s): 2022 2021 2020
Summary: This licence has been issued for the scientific research application No.5328. The objective of this project is to collect water quality data from regionally-representative lakes that can inform resource management decisions on cumulative impacts within the Northwest Territories (NWT). Using a computer program the research team will select 30 lakes within the Daring Lake area based on expect...


Development of a Biological Monitoring Program to Detect Change in Stream Health Along the Dempster–Inuvik–Tuktoyaktuk-Corridor
Principal Investigator: Musetta-Lambert, Jordan
Licensed Year(s): 2022 2021 2020 2019
Summary: This licence has been issued for the scientific research application No.5323. The purpose of this project is to establish a stream biomonitoring program along the Dempster–Inuvik–Tuktoyaktuk-Corridor to understand the current environmental conditions associated with past and newly developed road infrastructure. The research team will establish a stream biomonitoring program for the Inuvik to Tu...


The export of terrigenous dissolved organic carbon from boreal terrestrial ecosystems to the Arctic Ocean and its vulnerability to environmental change
Principal Investigator: Fichot, Cedric
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5291. The primary objective of this project is to develop a sophisticated model that can simulate the mobilization, transport, transformations, and export of Terrigenous Dissolved Organic Carbon (tDOC) from the Mackenzie River watershed to the Arctic Ocean. The model will be used to simulate the transfer of tDOC during the ...


Diavik Frame Lake Aerator Program
Principal Investigator: Sinclair, Sean
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5302. There are two objectives: 1) determine if installing an aerator in Frame Lake, Yellowknife, NT, will increase dissolved oxygen levels in the lake such that fish can be reintroduced; and 2) if phase 1 proves successful, transfer fish into Frame Lake and monitor growth and reproduction to determine if the population is ...


Understanding the potential impacts of rare earth elements in aquatic systems in the NWT.
Principal Investigator: McGeer, Jim
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5300. The objectives of the project are to develop data on the aquatic toxicology of rare earth elements in northern ecosystems and to contribute to water quality criteria for these metals. Three types of sample collections are proposed: 1) Water samples of approximately 0.5 L will be collected in pre-cleaned bottles ...


Terrain factors influencing the water quality of peatland streams along the Inuvik-to-Tuktoyaktuk Highway
Principal Investigator: Hille, Erika C
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5295. The objective of this project is to examine the oxygen (d18O) and hydrogen (d2H) isotopic compositions of stream water and precipitation for 11 peatland stream watersheds along the Inuvik-to-Tuktoyaktuk Highway (ITH). This information will be used to understand the hydrology of the contributing watershed. In particula...
