Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5173. The overall objective of the proposed study is to continue to study the physical limnology of Christie Bay in the East Arm of Great Slave Lake, NWT, Canada to develop a new scientific understanding of this unique area and to support studies of the sustainability of fish populations. All lake measurements will be ma...

Summary: This research will continue the long term objective of documenting and understanding the impacts of recent climate change on northern terrestrial and aquatic ecosystems. The short term objectives of my research for 2018 are: 1) to investigate the impacts of permafrost degradation and subsequent thaw slumping on freshwater ecosystems; 2) to examine the limnological implications of drained lakes on ...

Summary: The overall objective of this research is to improve the knowledge on lake ice and its effect on food webs/productivity in small Arctic lake systems in order to better predict changes that could occur under changing climate. The research involves the automated ice buoy and instrumented subsurface mooring system for continuous monitoring of weather conditions, lake ice cover (formation, growth o...

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 ...

Principal Investigator: Tank, Suzanne E
Licensed Year(s): 2013 2012
Summary: This study will examine the solar degradation of riverine dissolved organic carbon (DOC) to carbon dioxide (CO2) throughout the Mackenzie River Delta. During the spring runoff peak just before summer solstice, ice-jam flooding inundates the Delta with river water, which spreads out in a relatively thin layer over an extended area and is exposed to 24-hour Arctic sunlight. This water is then slowly...

Summary: The Arctic Great Rivers Observatory project studies the six largest rivers in the Arctic; the Mackenzie and Yukon Rivers in North America and the Ob', Yenisey, Lena, and Kolyma Rivers in Russia. The research team is interested in how climate change is impacting Arctic rivers. The team will make measurements of the concentration of naturally-occurring chemicals (like carbon and nitrogen) and try to...

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...

Principal Investigator: Lamoureux, Scott F
Licensed Year(s): 2012
Summary: The research team seeks to obtain sediment cores from two lakes in order to reconstruct past river flow in the region. This work, which builds on similar efforts at "Shellabear" lake, NWT, and work at Cape Bounty (Nunavut), will focus on long term river flow characteristics and the climate factors that control them. The fieldwork involves augering a hole in the lake ice and lowering a tube int...

Principal Investigator: Trusler, Scott
Licensed Year(s): 2012 2008
Summary: The objectives of the research studies are the following: refine understanding of baseline conditions; provide input to design mitigation; evaluate potential changes in the environment in relation to the Izok Project; and contribute to the ongoing data collection of the Arctic environment. The Minerals and Metals Group (MMG) Canada team of environmental consultants will collect and review exist...

Summary: To collect baseline environmental information for future environmental effects monitoring. Surveys will include fish, fish habitat, water and sediment quality, and geochemistry. Equipment for surveys will be limited to standard field measuring and surveying equipment, such as automated water quality monitors, GPS units, motorized inflatable boats, fixed wing aircraft and helicopters. An automat...
