Licensed Year(s): 2023 2022 2021
Summary: This licence has been issued for the scientific research application No.5551. The overall objective of the research is to eventually determine the environmental chemistry of the elevated metal concentrations, which will in turn determine the environmental risk that these measured concentrations pose (i.e. will answer, at least in part, the questions: do these sites require remediation, and in w...

Principal Investigator: Nearing, Michelle
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.5047. The objective of the study is to determine environmental conditions (in particular metal concentrations) and to compare existing conditions on and near the Rail Bed to background. The proposed field program will focus on collecting information that is considered critical for completing a human health and ecological ri...

Summary: Recent increases in fish mercury concentrations in the Mackenzie River basin are an environmental and human health concern. In several cases, new fish consumption advisories have been released by the NWT Health and Social Services for some lakes in the NWT. It remains unclear what processes are driving these trends in metal bioaccumulation. Two dominant hypotheses are: 1) new sources of long-range...

Licensed Year(s): 2007 2006 2005
Summary: Two projects will be conducted on Great Bear Lake. The first is a continuation of the lake-wide assessment of the stock structure, population characteristics and movements of lake trout involving the collection of up-to-date data from Dease, Smith, McTavish and McVicar Arms (last assessed in the early 1980’s). Smith Arm (66° 20’ N, 123° 16’ W, 280 km from Deline) will be studied in 2006. Data has ...

Principal Investigator: MacNeill, Scott W
Licensed Year(s): 2003
Summary: This 5-day sampling program will involve fisheries, aquatic, and vegetation studies at/in the vicinity of the abandoned Port Radium Mine site. Concentrations of five biologically significant metals (antimony, arsenic, lead, nickel and zinc) will be dete...

Summary: The research team will visit 11 fixed monitoring stations by boat. At each station, water samples will be collected at mid-depth for full chemical analyses (major ions, trace metals and nutrients) using the lowest commercially available analytical detection limits. At each station, samples will also be collected for zooplankton and phytoplankton biomass. Samples for taxonomy will be archived. ...

Licensed Year(s): 2001 2000
Summary: The objective of this study is two fold: a) to collect slimy sculpin tissue samples for baseline metal analysis; b) to monitor seasonal lake trout habitat utilization in Lac de Gras using radio telemetry methodologies. Twenty-five Slimy sculpins will be collected using baited minnow traps and opportunistic underwater netting, using professional SCUBA divers if available. Samples will be sent to ap...

Principal Investigator: Lawson, Nick
Licensed Year(s): 2001
Summary: The objectives of the research team are to collect baseline environmental information on the DeBeers Canada Exploration Ltd. project at Kennady Lake, to assist with the current environmental management of the property and prepare for an assessment of the environmental effects of potential future development of the site. Three field visits to Kennady Lake will be completed during the summer of 200...

Principal Investigator: Stoddart, Melissa
Licensed Year(s): 2000
Summary: This project developed out of the community concern's about the effect that local contaminants may have on their health and well being. The objectives of the study are: to obtain baseline data on the level of metals in fish from lakes that are commonly used as traditional harvesting grounds; to deliver the results of the study to the community and address local contaminant concerns; to provide co...

Principal Investigator: Thomas, Craig J
Licensed Year(s): 2000
Summary: This is a preliminary fisheries study to confirm 1989 baseline studies and to assist in impact assessment for Abandonment and Restoration (A & R) Plan for site closure. The researchers will conduct habitat assessments along drainages of Steeves Lake and Indin River (i.e. fish habitat mapping, assessment of habitat potential, 'spot check' confirmation of fish communities, the collection of instant...
