20212020 Summary:
This licence has been issued for the scientific research application No. 5696.
This main objective of this research project is to gain a better understanding of whether or not contaminant levels are changing in fish (lake trout and cisco) in Great Bear Lake. The research team is particularly interested in observing mercury presence. This study complements ongoing fish population studies being c...

This licence has been issued for the scientific research application No. 5669.
This research 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 research team has been studying since the early 1990s. The team plans to arrange collection...

Summary:
This licence has been issued for the scientific research application No.5278.
The main goal is to generate a specific knowledge about the implications of metals bioaccumulated observed in the population of three species of fish (e.g., northern pike, lake whitefish, yellow perch) and invertebrates (H. azteca) inhabiting ecosystems located in this mining region. The specific objectives are: 1) to...

Summary:
Tetra Tech modeled the effects of food chain accumulation of metals and exposure to metals on human health and ecological receptors. Tissue sampling of small rodents (and possibly hares) will be completed to identify trophic transfer of potential soil contaminants in order to verify the model.
Snap traps and pitfall traps will be set out by Tetra Tech Staff and two First Nations subcontractors....

Summary:
Between 1948 and 1951, approximately 375 000 tons of tailings were deposited directly into Back Bay from Giant Mine along the northwest shore via a drainage channel. The submerged tailings contain high levels of metals, particularly arsenic. Over time, t...
Principal Investigator:Landry, Francois Licensed Year(s):
2002
Summary:
The field work is intended to provide baseline fisheries data for four lakes (Horseshoe, Toss, Fay and Logan) and to obtain post-baseline fisheries data on eight lakes (Vulture, Kodiak, Nema, Cujo, Nanuq, Counts, and Slipper) within the Ekati claimblock...
Principal Investigator:Reed, Shawna Licensed Year(s):
1994
Summary:
In this study fish presence/absence and/or densities will be obtained by electrofishing representative habitat and the setting of baited minnow traps. When these two methods are not practical gill nets, trap nets, and/or beach seines will be employed. Each fish caught will be identified, measured, sexed and condition will be noted. Ten specimens of each species from each site (up to 10) will be...
Principal Investigator:Seagel, Graham Licensed Year(s):
1984
Summary:
A study to characterize aquatic environments potentially affected by tailings decant effluent, assess their sensitivity to project influences and develop baseline data for future monitoring purposes. Water, sediment and benthic envertebrate samples will be collected for analysis. Fish will be captured for tagging and to obtain tissue samples for metal analysis (subject to approval of DFO)....
Principal Investigator:Fallis, B.W. Licensed Year(s):
1984
Summary:
To assess the update of metals by sediments and biota in the vicinity of Nanisivik Mine and the Polaris Mine. The data will be used to monitor the extent to which metal concentrations in sediments and biota have changed since similar studies were conducted in 1980 and 1981....
