Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2024 2020 2019
Summary: This licence has been issued for the scientific research application No. 6000. The study is continuing to investigate whether contaminant (mercury, other metals, persistent organic contaminants) levels are changing in fish in the Northwest Territories with a focus on Great Slave Lake which the team have been studying since the early 1990s. The plan is to arrange collections of lake trout from t...

Summary: This licence has been issued for the scientific research application No.5031. The study is continuing to investigate whether contaminant levels are changing in fish in the Northwest Territories with a focus on Great Slave Lake which we have been studying since the early 1990s. The research team plans to collect lake trout from Great Slave Lake (Hay River area and Lutsel K’e area and also plans ...

Principal Investigator: Hung, Hayley
Licensed Year(s): 2020
Summary: This licence has been issued for the scientific research application No.4494. The goal of the passive sampling network is to expand the number of sampling locations to get a more comprehensive understanding of the level of persistent organic pollutants (POPs) and mercury entering the region, where the pollutants are coming from and how they are changing over time. To provide spatially-distribut...

Principal Investigator: Evans, Marlene S.
Licensed Year(s): 1995 1994
Summary: The researchers will collect samples of sediments from the bottom of Great Slave Lake at sites near Fort Resolution and Lutsel K'e. This data will allow a better understanding of how fast sediments are deposited on the lake bottom in various regions. Researchers will also collect invertebrates and fish samples as part of an overall study of contaminants in the lake's ecosystem....

Principal Investigator: Gregor, Dennis J.
Licensed Year(s): 1993
Summary: Contaminants are carried in the air to the arctic during the winter when large-scale wind movements bring these contaminants from industrialized locations in North America, Europe and Asia to the north. Snow can collect these compounds from the air and bring them to the ground where they can accumulate. Thus, it is important to study the amount of contaminants in snow to determine the types and ...

Principal Investigator: Gregor, Dennis J.
Licensed Year(s): 1992 1991 1991 1990
Summary: Snow samples will be collected from approximately 30 sites across the NWT and Yukon in the spring of the year. This annual snow pack sample will allow an estimate of the quantity of organic contaminants that have been deposited over the winter season. To better understand the fate of these contaminants in the High Arctic, the researchers will undertake an intensive small basin study on Cornwallis ...

Principal Investigator: Evans, Marlene S.
Licensed Year(s): 1992
Summary: The Researchers will collect a series of sediment and water samples. These will be analyzed for plant nutrients, concentration of microscopic plant cells, bacteria, suspended solids, dissolved oxygen and organic contaminants. Microscopic animals will also be netted. They will determine the abundance and composition of the animals and conduct experiments to measure their feeding rates and fat cont...
