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.
Licenced 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 ...


Con Mine Phase 6 EEM - Periodic Monitoring
Principal Investigator: Irving, Elaine
Licenced Year(s): 2018 2015 2012 2009 2007
Summary: The objective of the study is to carry out the third year of periodic monitoring of fish and benthos at the determined study locations; Jackfish Bay (exposure area), Horseshoe Island Bay (reference area for fish survey) and Kam Bay (reference area for the benthos survey), to determine if treated Con Mine effluent is affecting fish and fish habitat. The study has been designed to replicate the stud...


SAMMS: Sub-Arctic Metal Mobility Study
Principal Investigator: Wolfe, Brent BBW
Licenced Year(s): 2018
Summary: The seven-year objective of Sub-Arctic Metal Mobility Study (SAMMS) is to identify, quantify, and predict mobility of natural-source and legacy mine-source metals in soil, wetlands, and lake sediments that extend from former, present, and planned mine sites currently and as climate change alters the quantity and quality of dissolved organic matter produced and exported in subarctic NWT watersheds....


Analysis of microplastic in a wilderness river system
Principal Investigator: Horobin, Ric
Licenced Year(s): 2018
Summary: The Mackenzie River drainage basin is the second largest drainage basin in North America and is predominantly sparsely populated. The Peel and Wind River systems flow into the Mackenzie from an almost entirely uninhabited wilderness. The research team are undertaking a canoe expedition down the Wind, Peel and Mackenzie River system. The route starts in a region of almost no development (the Win...


Identifying sources of mercury in Arctic rivers
Principal Investigator: Zdanowicz, Christian M
Licenced Year(s): 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 ...


Community-Based Water Quality Monitoring in the Northwest Territories
Principal Investigator: Somers, Gila L
Licenced Year(s): 2018 2017 2016 2015 2014 2013
Summary: Water quality monitoring equipment has been deployed at over 42 sites across the NWT to address community concerns. Community members were trained to use the following equipment: •YSI sondes: sit in the water and measure basic water quality parameters every 2 hours for up to 3 months. Analysis undertaken at ENR. •Grab water samples: measure basic parameters, nutrients, physicals, major ions,...


Environmental Quality at Pine Point
Principal Investigator: Dudley, Judy
Licenced Year(s): 2018
Summary: The purpose of the study is to verify baseline conditions within the Pine Point District study area. Field sites will be accessed by truck, on foot, and on ATVs during the ice-free growing season. The study may include analysis of previously disturbed sites to evaluate regeneration and succession, surveys of former mine pits, collection and analysis of surface water and groundwater samples, g...


Diavik Aquatics Effects Monitoring Program
Principal Investigator: Wells, David A
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2005 2004 2003 2002 2001
Summary: The objective of this project is to revisit fixed sample stations at near-field, mid-field and far-field sites over the course of the year in an effort to determine any seasonal variation that may exist and confirm impact predictions. The Aquatic Effects Monitoring Program (AEMP) Version 3.5 will consist of the following components; Traditional Ecological Knowledge, Dust Deposition; Effluent an...


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
Licenced 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
Licenced 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...
