Ekati
Principal Investigator: Donald, Derek
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5765. The main objectives of the field work for 2023 will be (1) to determine if the Ekati Diamond Mine is having an effect on the surrounding aquatic environment, wildlife, and air quality; and (2) to provide baseline data for areas where mine development may occur in the future. In winter, water samples will be colle...


Diavik Frame Lake Aerator Program
Principal Investigator: Sinclair, Sean
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No. 5773. This research project has 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; 2) if objective 1 proves successful, transfer fish into Frame Lake and monitor growth and reproduction to determine if t...


What is the impact of metal contamination from mining activities in the Yellowknife area on northern pike (Esox lucius) and H. azteca populations?
Principal Investigator: Rosabal, Maikel
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 55584. Considering the results obtained in our previous studies on fish and invertebrates, our main goal is to generate a specific knowledge about the implications of metals bioaccumulated observed in the population of northern pike and invertebrates (H. azteca) inhabiting ecosystems located in this mining region. Our spec...


Understanding the potential impacts of rare earth elements in aquatic systems in the NWT.
Principal Investigator: McGeer, Jim
Licensed Year(s): 2023 2022
Summary: This licence has been issued for the scientific research application No. 5681. The objectives of this research project are to: 1) develop data on the aquatic toxicology of rare earth elements in northern ecosystems; 2) to contribute to water quality criteria for these metals. Three types of sample collections are proposed. These would be done at selected sites along the Ingraham Trail (hi...


Monitoring cumulative effects to water quality: An NWT Pilot Study - expanded to include aquatic invertebrates
Principal Investigator: Chin, Krista
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5647. The main objective of this research project is to further inform the story of how cumulative effects impact lake systems in the Yamba River basin. The research team intends to accomplish this by collecting benthic macroinvertebrates in 70 lakes in the Yamba River basin to compliment water quality data that were colle...


TERRE-NET: Controls on the Release of Contaminants from Gold Tailings at the Giant Mine, Yellowknife, NT
Principal Investigator: Blowes, David W.
Licensed Year(s): 2024 2023 2022 2021 2020 2019 2018 2017
Summary: This licence has been issued for the scientific research application No.5447. The objectives of this project are to: 1) determine the magnitude and rate of release of arsenic and other toxic elements from the Giant Mine tailings to groundwater; 2) evaluate remediation alternatives for tailings management, including the effects of proposed engineered covers; and, 3) apply novel characterization ...


Understanding of distribution and sources of polybrominated diphenyl ethers in the north and east of Great Slave Lake and coastal regions
Principal Investigator: Chen, Bing
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No.5251. The proposed project will evaluate the temporal and spatial distribution of Polybrominated diphenyl ethers (PBDEs) 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 be de...


Recovery of the Mine-impacted Landscape in the Yellowknife Region
Principal Investigator: Palmer, Mike
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5534. The long-term objective of this research is to determine what processes control the recovery of the landscape near Yellowknife that was contaminated by stack emissions from the Giant Mine roaster, and how this recovery will be affected by climate change and unusual or severe weather events. One focus will be on how cl...


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...
