Summary: The long term goals of this research are: 1. to identify and quantify the physical, chemical and ecological processes that affect contaminant transfer in Arctic aquatic food webs in response to observed and predicted climate variability & change in the Husky Lakes Watershed (HLW); and 2. to provide people and regulators of Inuvik and Tuktoyaktuk with tools to effectively monitor selected highly...

Summary: This study will provide current information about the health of some subsistence predatory fish in ten commonly used lakes by residents of the Sahtu Settlement Area (SSA). This investigation may help to identify alternative sources of fish from lakes not impacted to the degree as seen in Kelly Lake. A future, far more thorough study of mercury abundance and bio-magnification trends may also result...

Summary: The objective of this study is to collect whitefish and lake trout in the Keith Arm of Great Bear Lake near Deline and analyze tissues for metals and radionuclides. The results of this study will supplement the results of a study conducted in 2009 which reported the concentrations of metals, radionuclides and organo-chlorine pesticides in a small number of trout and herring. Twenty whitefis...

Principal Investigator: Widmeyer, Joline
Licensed Year(s): 2010
Summary: The objective of this study is to identify what fish species are in Ruth Lake and Bullmoose Lake and to conduct tissue sampling which will assist in determining if the fish in these lakes are bioaccumulating heavy metals. Fish will be sampled using techniques such as minnow trapping, seining, gill netting, angling and possibly boat electrofishing. Nets and minnow traps may be left at the sam...

Principal Investigator: Katz, Sharon
Licensed Year(s): 2009
Summary: The objectives of this study are: (a) To determine whether brominated flame retardants (BFRs), current use pesticides (CUPs), perfluorinated compounds (PFCs), and mercury bioaccumulate using the vegetation-caribou-wolf food chain and the Bathurst caribou herd as a model; (b) To explore possible sources of lead contamination in the Bathurst herd caribou; (c) To elucidate the pathway of lead uptake ...

Principal Investigator: Ford, Bruce S
Licensed Year(s): 2005
Summary: This study involves fish sampling to determine relative abundance and levels of mercury and other metals in fish tissue in Giauque Lake, Thistlethwaite Lake and Control Lake A, as well as benthic invertebrate sampling and water quality sampling in the three lakes to complement the fish sampling. 3 sites in Giauque, 3 in Thistlethwaite and one in Control Lake A will be recorded. Captured fish will ...

Summary: Air quality is an issue at mine sites, and diamond mining can contribute large quantities of dust to the air. This dust may contain elevated levels of heavy metals. Vehicle and generator exhausts also contribute to air pollution and greenhouse gases. To acheive the goal of sustainable development, Diavik policy focuses on the need to identify potential risks and set targets for pollution preventio...

Summary: The extensive wetland complex in Wood Buffalo National Park (WBNP) is composed of a mosaic of shallow ponds that are unique in Canada. They are also the nesting grounds of the last migratory population of Whooping Cranes. Water, organic matter, aquatic plants and small aquatic life forms will be sampled from ponds just outside the nesting area and 0.5 km from the highway. The research team will ...

Principal Investigator: Steinecke, Karin
Licensed Year(s): 1998 1997
Summary: The project will focus on understanding, analyzing and evaluating the reactions of the northern boreal forest ecosystems in the Great Slave Lake region due to man made stress of mining, settlement and connecting activities. The project will try to develop some general conclusions, statements and model systems. The research team (2 persons) will come from Europe to Yellowknife by plane. The base wi...

Principal Investigator: Carolsfeld, Joachim
Licensed Year(s): 1996
Summary: The researchers propose to collect invertebrates, algae and microorganisms with the use of SCUBA, plankton nets, bottom dredges, and intertidal collection. These samples will be sorted and frozen for later analysis in Halifax. The researchers wish to collect samples in about 25 sites, ranging from the southern tip of Liverpool Bay to south of Saunatuk. All collections will take place from small...
