Joint Ocean-Ice Study (JOIS)
Principal Investigator: Williams, Bill
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5939. Research questions seek to understand the impacts of global change on the physical and geochemical environment of the Beaufort Gyre (BG) Region in the Canada Basin of the Arctic Ocean and the corresponding biological response. We thus collect data annually so that we can link decadal-scale perturbations in the Arctic...


Great Bear Lake Water Monitoring
Principal Investigator: Kheyrollah Pour, Homa
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5678. The contamination and pollution objectives for this research project are as follows: 1) identify and monitor potential sources of contamination and pollution in the lake, including runoff, and sewage; 2) measure and track levels of pollutants such as heavy metals, pesticides, nutrients (e.g., nitrogen and phosphorus)...


Recent, rapid environmental change in the western Canadian Arctic
Principal Investigator: Thienpont, Joshua
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5573. To understand how landscape changes caused by climate warming are impacting aquatic ecosystems, particularly lakes and streams. These disturbances focus primarily on permafrost thaw, in the form of thaw slumps and landslides. The understanding derived will allow better understanding of how water quality and aquatic ha...


Freshwater biodiversity spanning contaminant gradient from historical gold mines in Yellowknife NWT region
Principal Investigator: Derry, Alison
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5253. The long-term project objective is to determine ecological and evolutionary processes, and interactions between ecology and evolution (eco-evolutionary interactions), that are potentially limiting and/or facilitating the biological recovery of mining-impacted lakes around Yellowknife, NWT. The objective in the first y...


Nitrogen sources for Arctic freshwaters (NitroFresh)
Principal Investigator: Pastor, Ada
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.5034. The main aim of Nitrofresh is to assess the nitrogen (N) sources for streams and the linkages between terrestrial and freshwater ecosystems across different regions with continuous permafrost in High Arctic. In particular, the research team have three objectives: 1) to quantify and characterize N pools along the ripar...


Long-term hydrological dynamics of Canada’s largest watershed: Climate controls on water quantity of the Mackenzie River Basin
Principal Investigator: Galloway, Jennifer
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...


Understanding Changes in the Freshwater Ecosystems and Drinking Water in Northern Canada
Principal Investigator: Spicer, Neal
Licensed Year(s): 2017
Summary: The Objectives of this research are to: 1) determine where the participating communities obtain their drinking water from within their home and while on the land and why; and determine the areas of each region that are considered valuable and important areas of water quality; and 2) determine what the concerns are concerning the sources of water, both within the homes and natural water sources, ...


Assessing the impact of small, Canadian Arctic river flows to the freshwater budget of the Canadian Archipelago
Principal Investigator: Alkire, Matthew B
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...


Improving Habitat Connectivity to Enhance Productive Capacity of Arctic Freshwater Ecosystems
Principal Investigator: Tonn, William
Licensed Year(s): 2014 2013 2012 2011 2010 2009
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 ...


Examining the impacts of climate change on aquatic and terrestrial ecosystems of the Mackenzie region, NWT
Principal Investigator: Pisaric, Michael FJ
Licensed Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The objectives of this research are to examine the impacts of climate and environmental change on freshwater ecosystems in the Inuvik region across a variety of spatial and temporal scales. Specifically, the team is examining the impacts of permafrost degradation and subsequent thaw slumping on freshwater ecosystems and the impact of climate change on tree growth in the Mackenzie Delta. Lake s...
