Summary: This licence has been issued for the scientific research application No. 5936. The broad research question is: How will beaver activity in the tundra impact aquatic ecosystem health? This will be answered by addressing the following specific objectives and questions: Generate an understanding of beaver activity impacts on aquatic food webs in tundra streams. Question 1: How does beaver activit...

Summary: This licence has been issued for the scientific research application No.4985. The objectives of this project are to investigate impacts of permafrost slumping on water quality, benthic macroinvertebrate communities, fish communities and ecosystem function by (a) advancing research on previously studied thaw slumps within the Stony Creek Watershed and include unstudied (for biotic metrics) thaw ...

Principal Investigator: Gray, Derek K
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4966. The purpose of the proposed project is to improve the understanding of the effects of road development on lakes in Canada’s north. To achieve this purpose, the research team will pursue two objectives: 1) to determine if changes in water quality caused by road dust affects invertebrate communities (bugs and waterfleas...

Licensed Year(s): 2016
Summary: The objective of this project is to document the physical condition of the seabed lease following the removal of the Tarsiut Caissons. The project also includes sampling benthic populations in the disturbed and undisturbed areas of the lease. This information can be used as a benchmark for possible future study of the effects of natural processes in restoring the footprint of the caissons. A bathy...

Summary: This study will examine the effects of permafrost and flooding on the ecological structure and carbon exchange of contrasting lakes in the Mackenzie River Delta. Patterned ground marked by ice-wedge polygons is formed by freezing and thawing of the soil, which forms cracks into which ice can spread and cause the soil to uplift. These processes have effects on the hydrology and water chemistry of a...

Principal Investigator: Barber, David G.
Licensed Year(s): 2008 2007
Summary: The Circumpolar Flaw Lead (CFL) system study is designed to examine the importance of climate processes in changing the nature of a flaw lead system and the Arctic marine environment in the Northern Hemisphere, and the effect these changes will have on the marine ecosystem, contaminant transport, carbon fluxes, and greenhouse gases. Using the Canadian Research Icebreaker (CCGS Amundsen), the team ...

Summary: Project a: essentially fifth year of research (sixth-year if associated work in 2000 is counted), and seeks to continue heretofore successful investigations into the nature, substance and long-term effects of contact between Copper Inuit and Europeans/Eurocanadians in the 19th and 20th centuries utilizing sociocultural, archaeological, and economic methodologies, b. Project seeks to initiate a col...

Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2009 2008 2007 2006
Summary: This study is designed to fill gaps in Environment Canada’s understanding of the aquatic environment potentially impacted by various aspects of the Mackenzie Gas Project (MGP). Potential stressors including: increased erosion, nutrient releases from sewage discharges, other chemical releases, water withdrawals, impacts of barge traffic, increased atmospheric emissions, etc. The focus will be on th...

Principal Investigator: Edinger, Evan N
Licensed Year(s): 2005
Summary: Climate change is affecting coastlines and coastal communities across Arctic Canada. Communities in the Western Arctic, including Sachs Harbour, have described a variety of effects, including warmer temperatures, reduced sea ice thickness, longer duration of open water in summer, increased wave activity, and new or early arrivals of migratory animals. These effects can have a variety of impacts ...

Principal Investigator: Halliwell, Douglas
Licensed Year(s): 2004
Summary: The objectives of this program are; 1) to characterize baseline water, sediment, and benthic invertebrate conditions in one experimental lake (Parsons Lake) and two control lakes near the Mackenzie Gas Project's (MGP) Parsons Lake Anchor Site; 2) to cho...
