Summary: Thaw slumps are one of the most dramatic thermokarst features in permafrost regions. The number of thaw slumps on Banks Island has more than tripled in recent decades and it is likely that this change is altering terrestrial and aquatic ecosystems. This multidisciplinary research project investigates the short- (1960s-present day) and long-term (Medieval Warm Period to today) impacts of permafrost...

Summary: To collect baseline aquatic data in advance of the development of the Prairie Creek Mine. The study will be part of the Aquatic Effects Monitoring Program (AEMP) and will satisfy the requirements of the federal Environmental Effects Monitoring (EEM). The description below is a summary of the planned methodology. Most work will be carried out on Prairie Creek; however, sampling will also be con...

Summary: The Tlicho Lands Moratorium was lifted in June 2013, and development pressure is expected to increase on Tlicho Lands. As Tlicho Lands are in relatively pristine condition, the intent of this study is to begin to collect baseline data at sites prioritized by community members away from specific project footprints in order to analyze the cumulative impacts of development, climate change, and increa...

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): 2013
Summary: The primary objective of this research program is to collect baseline data on: 1) water chemistry, limnologic profiles, sediments, plankton, benthic invertebrates and aquatic habitat; and, 2) fish presence and collection of fish tissue for metal analysis. Aquatics: The Aquatics field program will be conducted in the spring of 2013. During the field program, the following samples will be coll...

Summary: The objectives of this research project are: to study the freshwater ecology, hydrology, and hydraulics of small lakes and streams in the Lac de Gras basin before habitat modification; to monitor the changes in ecosystem productive capacity resulting from habitat modifications designed to increase habitat connectivity and fish passage; and to assess the effectiveness of such habitat modifications ...

Summary: The objective of the 2012 Aquatics program is to continue baseline data collection to further characterize the baseline water and sediment quality and aquatic communities at specific lakes within the Thor Lake area and Avalon's Thor Lake Rare Earth Elements Project footprint. Water, sediment and aquatic organisms will be collected at up to 11 stations (10 lakes) within the Thor Lake area. Most ...

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 ...

Summary: The objectives of this research are: (1) to determine length, weight, and general condition of 100 fish and tissue analysis of not more than 10 fish (Slimy Sculpin- Cottus cognatus) per site at five site locations in the Flat River: two locations upstream of the CanTung mine site, one adjacent to the mine site and at two locations downstream of the mine site; and, (2) to determine sediment and wa...

Summary: This is a multidisciplinary project involving communities, governments and academic researchers. The goals are to : 1) inventory and track broad scale changes in landscape disturbances; 2) determine the impacts of natural and anthropogenic disturbances on the physical and chemical characteristics and ecology of streams and rivers; 3) determine disturbance thresholds relevant to the health of strea...
