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): 2019
Summary: This licence has been issued for the scientific research application No.4590. 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 ...


Taltson Twin Gorges Hydro Generating Facility Aquatic Effects Monitoring Program (AEMP) 2019
Principal Investigator: Miller, Matthew
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4565. The objective of this project is to conduct Aquatic Effects Monitoring. This will include three parts: 1) Riparian Habitat and Fish Usage Assessment. This is a study to monitor the trends and fluctuations of the aquatic environment along the riparian zones within the Taltson River from Nonacho Lake to Twin Gorges ...


Sanguez Lake Fish Down Study
Principal Investigator: Low, George
Licensed Year(s): 2019 2018 2017
Summary: This licence has been issued for the scientific research application No.4573. The objectives of this study are to: 1) establish a population estimate of walleye in Sanguez Lake; 2) establish an additional estimate of fish mercury concentrations in walleye and pike. In 2013, mean mercury concentration in walleye was 0.71 mg/kg wet weight, and in pike was 1.09 mg/kg wet weight; 3) reduce the n...


Temporal trend studies of trace metals and halogenated organic contaminants (HOCs), including new and emerging persistent compounds, in Mackenzie River burbot, Fort Good Hope, NWT.
Principal Investigator: Stern, Gary
Licensed Year(s): 2019
Summary: The short-term goals are to determine if 2019 burbot contaminant concentrations: 1) remain below Health Canada guidelines (i.e. <0.5 ppm mercury per gram fish); 2) are associated with dietary indicators to determine the influence of diet (via stable isotope ratios) on contaminant concentrations in current fish, although previous results suggested no association; and, 3) as well as to look for link...


Identifying sources of mercury in Arctic rivers
Principal Investigator: Zdanowicz, Christian M
Licensed Year(s): 2019 2018
Summary: The goal of this project is to identify and quantify (measure) the different possible sources of toxic mercury that is transported in rivers of the Mackenzie River basin, all the way down to the Beaufort Sea. In particular, the research team want to establish how much mercury comes from "modern" sources (like distant air pollution, runoff from rain/snow, wash-out from surface soils, etc.) and how ...


NTPC Bluefish Hydro
Principal Investigator: Panayi, Damian
Licensed Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010
Summary: The multiyear monitoring programs at Bluefish accomplish the following objectives: • Monitoring effects to fish habitat from changes in water level and flow through Reach 1; • Monitoring of the seasonal use of Reach 1 and the Tailrace Area by spawning fish; • Monitoring of mercury concentration in large-bodied and small-bodied fish; • Continue winter investigations of egg incubation conditions...


Spatial and long-term trends in persistent organic contaminants and metals in lake trout and burbot from Great Slave Lake
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2018 2016
Summary: This study is continuing to investigate whether contaminant levels are changing in fish in Great Slave Lake which the team have been studying since the early 1990s. The research team will collect lake trout from the Hay River and Lutsel K’e areas. The team will also plan to collect burbot from the Lutsel K’e and Fort Resolution areas of Great Slave Lake, and northern pike from the Fort Resolution ...


Temporal trend studies of trace metals and halogenated organic contaminants (HOCs), including new and emerging persistent compounds, in Mackenzie River burbot, Fort Good Hope, NWT
Principal Investigator: Stern, Gary
Licensed Year(s): 2018
Summary: The short-term goals are to determine if 2018 burbot contaminant concentrations: 1) remain below Health Canada guidelines (i.e. <0.5 ppm mercury per gram fish); and 2) are associated with dietary indicators to determine the influence of diet (via stable isotope ratios) on contaminant concentrations in current fish, although previous results suggested no association (Carrie et al. 2010); as well as...


Metals levels in large bodied fishes near impacted lakes near Yellowknife, NWT
Principal Investigator: Somers, Gila L
Licensed Year(s): 2018 2017 2016
Summary: The objectives of this project are to collect fish tissue samples from species of subsistence importance to: 1) establish a long-term community monitoring program for contaminants in fish; and, 2) to monitor potential spatial and temporal trends in metal concentrations (including mercury) in fish tissues within the Yellowknife region. The data acquired will be added to existing and concurrently co...


Productivity and mercury trends in Great Bear Lake
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2018
Summary: The objectives of this research project are to collect sediment cores from up to six sites in Great Bear Lake to investigate the temporal record of diatom and lake productivity and the deposition of mercury and other metals; to investigate spatial gradients in lake productivity as influenced by station depth, distance from shore, and river influences; and to continue to investigate mercury levels ...
