The water quality response of Arctic rivers to regional variability in landscape and permafrost conditions
Principal Investigator: Hille, Erika C
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No. 5596. The objectives of this study are to conduct spatially detailed surveys of water quality and stream discharge along the Miner River, in order to examine how water quality responds to organic-rich peatland tributary streams and retrogressive thaw slumping; and, to examine the seasonal water quality of Caribou Creek and...


Understanding of distribution and sources of polybrominated diphenyl ethers in the north and east of Great Slave Lake and coastal regions
Principal Investigator: Chen, Bing
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No. 5820. The proposed project will evaluate the temporal and spatial distribution of Polybrominated Diphenyl Ethers (PBDE) in the water and sediment of Great Slave Lake and surrounding communities, landfills, drinking water, and industries to identify the source of PBDEs. The concentration and distribution of PBDEs will b...


Permafrost slumping and land-water connections on the Peel Plateau
Principal Investigator: Tank, Suzanne E
Licensed Year(s): 2024 2023 2022 2021
Summary: This licence has been issued for the scientific research application No. 5597. The objective of this research is to understand how permafrost slumping increases the mobilization of carbon, nutrients, and toxins (mercury) from land to water, and the effects of this transport on stream ecosystems and the global carbon cycle. Over the next several years, the research team plan to measure stream ch...


CEAS
Principal Investigator: Rutter, Nick
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5463. The objectives of this project are to develop improved understanding of, and ability to predict, snowcover properties from numerical models used to simulate climate and hydrology in northern regions; to consider the integrated effect of climate on vegetation, snow, permafrost, and lakes; and, to develop improved predi...


Arctic Great Rivers Observatory 4
Principal Investigator: Holmes, Robert M
Licensed Year(s): 2024 2023 2022 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: This licence has been issued for the scientific research application No.5441. 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 are interested in understanding how climate change is impacting Arctic rivers. The team take measurements...


Terrain factors influencing the water quality of peatland streams along the Inuvik-to-Tuktoyaktuk Highway
Principal Investigator: Hille, Erika C
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5295. The objective of this project is to examine the oxygen (d18O) and hydrogen (d2H) isotopic compositions of stream water and precipitation for 11 peatland stream watersheds along the Inuvik-to-Tuktoyaktuk Highway (ITH). This information will be used to understand the hydrology of the contributing watershed. In particula...


Seasonality of streamwater and icing chemistry in the Yellowknife, NT area
Principal Investigator: Tank, Suzanne E
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5138. The objectives of this study are to determine the influence of permafrost thaw on the mobilization of carbon to stream ecosystems, and its subsequent effects on in-stream microbial communities and carbon cycling. The research team will measure stream water chemistry and collect water samples for microbial analysis at ...


Nutrient and contaminant status in the wetlands of the Slave River Delta
Principal Investigator: Doig, Lorne
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4988. The objectives of this project are to determine: 1) From the outer Slave River Delta (SRD) (river-water dominated) to the apex of the SRD (runoff dominated), what the current status of nutrients and contaminants in SRD wetland ecosystems are; 2) How trace elements (e.g., mercury) move through SRD wetland food webs; an...


Changing Carbon Sinks in Sub-Arctic Canada
Principal Investigator: Schiff, Sherry L
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.4703. The objective is to improve the quantitative understanding of carbon dynamics in Canadian subarctic freshwaters, with a focus on identifying the processes governing the balance between carbon sinks and carbon sources to the atmosphere. The research team will pair field-based observations with laboratory experiments...


Assessment of the Western Arctic Boundary Current
Principal Investigator: Pickart, Robert S.
Licensed Year(s): 2020
Summary: This licence has been issued for the scientific research application No.4747. The main objective is to characterize the western Arctic Boundary current, which flows at the edge of the shelf, in order to understand its role in dictating shelf-basin exchange of water and materials and how it impacts the ecosystem of the region, including the occurrence of marine mammals. This project is a coll...
