Investigating the cumulative effects of environmental change and human activity in the Tathlina watershed
Principal Investigator: Laidlaw, Shawn
Licensed Year(s): 2013 2012
Summary: The purpose of this project is to: 1) coordinate monitoring and research efforts in the watershed between the community, government, and universities; 2) understand current aquatic health of the watershed using water quality, macroinvertebrates, aquatic furbearers and fish as indicators of ecosystem health; 3) understand historical environmental change and contaminant loading in the watershed u...


The Arctic in Flux: How has Recent Climate Change Affected Contaminant Transport and Uptake in Aquatic Arctic Systems?
Principal Investigator: Blais, Jules M
Licensed Year(s): 2013 2012
Summary: This research will determine how the recent and dramatic climate changes in Arctic freshwater have affected the transport and fate of anthropogenic contaminants to freshwater systems, two of the largest threats facing northern communities and ecosystems. This research will develop new tools to examine how the fate of anthropogenic contaminants is affected in Arctic regions under different climate ...


Arsenic sequestering in wetlands adjacent to the Terra Mine tailings lake, Northwest Territories
Principal Investigator: Sealey, Heather N
Licensed Year(s): 2009
Summary: Arsenic was introduced to Ho-Hum Lake when it was used as a tailings pond during mining activities at Terra Mine, of the Silver Bear Mines Group. The objective of this study is to determine how arsenic is being removed from the lake water by a wetlands area. The intention for collecting data will include water and sediment sampling in Ho-Hum Lake, Moose Bay, and the wetlands between them. Seq...


UrEnergy 2006 Screech Lake Baseline Program
Principal Investigator: Schryer, Rick P.
Licensed Year(s): 2006
Summary: Sampling of water, sediment, benthic invertebrates, fish inventories, and fish habitat mapping will be done. Water will be collected for chemical analysis, and limnology measurements taken. Sediment will be collected for chemical analysis and particle size analysis. Benthic invertebrates will be collected for taxonomic identification. Fish species, presence and relative abundance will be determine...


2005 Aquatic Monitoring Program - EKATI Diamond Mine
Principal Investigator: Muggli, Deborah
Licensed Year(s): 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003
Summary: The main objective of the field work to be performed in 2005 is to determine if the EKATI mine is having an effect on its surrounding aquatic environment and to provide baseline data for the area. Transportation to and from site will be provided by BHP Billiton. The primary form of transportation of personnel and equipment will be via regularly scheduled Canadian North flights to site. While ...


Investigation of factors affecting high mercury levels in fish in lakes in the Mackenzie River Basin (2002-2003)
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2003 1998
Summary: This study is based on earlier research conducted by the Department of Fisheries and Oceans which found that fish in many lakes in the Mackenzie River Basin had high mercury concentrations. This study examines the environment in which the fish live in o...


Environmental study of the aquatic resources of the Thonokeid Lake area
Principal Investigator: Couture, Richard
Licensed Year(s): 1994 1994 1993
Summary: The researchers of Rescan have been contracted by B.H.P. Minerals Canada Ltd. to conduct an assessment of the types of fish and other aquatic organisms that are found in the Thonokeid Lake area. Tissue samples will be collected in order to assess heavy metal contaminants in fish. An environmental report will be submitted to the Territorial Government on the results of this study....

Influence of the Slave River on Great Slave Lake
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 1992
Summary: The Researchers will collect a series of sediment and water samples. These will be analyzed for plant nutrients, concentration of microscopic plant cells, bacteria, suspended solids, dissolved oxygen and organic contaminants. Microscopic animals will also be netted. They will determine the abundance and composition of the animals and conduct experiments to measure their feeding rates and fat cont...
