Licensed Year(s): 2020
Summary: This licence has been issued for the scientific research application No.4705. The Mackenzie River Basin (MRB) is one of the largest cold-water, intact boreal ecosystems in the world and has unique Earth-system’s processes associated with sea ice formation, global circulation of deep ocean currents, carbon storage, and biogeochemical cycling. This unique global resource is also critical for supp...

Summary: This licence has been issued for the scientific research application No.4663. The primary objectives of this research are: 1) to develop and test new methods of monitoring permafrost landscape change; 2) to investigate the impacts of natural and human disturbance on permafrost terrain and the ground temperature conditions in natural environments and in communities; and 3) to assess the physical...

Principal Investigator: Gammon, Paul R
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4544. The objectives of this research are: 1) To investigate the environmental chemistry of the borrow pits and immediate surrounding areas to determine what, if any, environmental risk do the elevated concentrations represent; 2) To investigate the environmental chemistry of an undisturbed area around the Inuvik to Tukto...

Summary: The primary objectives of this study are to: 1) understand and explain the role of snow microstructure in terms of the radar backscatter and phase response in this environment 2) to evaluate the efficacy of differential synthetic aperture radar (dInSAR) for snow accumulation estimates at C-band, and 3) to evaluate the optimal approach to estimating snow water equivalent using radar from this site....

Principal Investigator: Kasook, Davonna C
Licensed Year(s): 2018 2017
Summary: The objective is to compare differences in snow depth, density and morphology of a heavily forested site and a tundra site. The Principal Investigator (PI) will study the effect landscape (forest vs. tundra) has on seasonal snow pack evolution and physical properties (density, temperature, snow grain morphology, and stratigraphy) of the snowpack. These results will be compared to historical data (...

Principal Investigator: Charette, Matthew
Licensed Year(s): 2016
Summary: The objectives are to measure a suite of trace elements and isotopes (TEIs) in the active layer and permanently frozen layer of permafrost cores sampled near the Mackenzie River, and to compare these concentrations to those observed in submarine groundwater discharge and Mackenzie River discharge in order to determine whether permafrost-associated TEIs are being transported to the coastal Arctic. ...

Licensed Year(s): 2016 2015 2014
Summary: There are two primary goals of this project: 1) to determine whether relatively small Canadian Arctic rivers significantly contribute to the total volume of freshwater that drains through Davis Strait; and, 2) to determine if they are chemically distinct from larger North American rivers such as the Mackenzie and Yukon Rivers. To achieve these goals the research team propose to collect water sampl...

Summary: The Objectives of this research are to: 1) Improve our understanding of microbial carbon-processing in Mackenzie Delta lakes and how it is affected by the changing water levels; and 2) Decipher the impact of water level changes on the ability of the Mackenzie Delta to affect riverine nutrient flow to the ocean. Specific activities for the coming field season include the following: (Goal 1) I...

Principal Investigator: Lacelle, Denis
Licensed Year(s): 2015
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: 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 research team will take measurements of the concentration of naturally-occurring chemicals (like carbon and nitrogen) a...
