Vulnerability of northern drinking water sources to environmental change
Principal Investigator: Comte, Jerome
Licensed Year(s): 2023 2022
Summary: This licence has been issued for the scientific research application No.5418. The overarching goal of this project is to assess the implications of climate change on drinking water quality and practices, and to implement a community-based monitoring program. Specifically, the research team will: 1) engage and work with local communities to co-design and undertake a drinking water quality monito...


Natural Resources Canada - Canadian National Seismograph Network Operations
Principal Investigator: McKee, Lorne
Licensed Year(s): 2023 2022
Summary: This licence has been issued for the scientific research application No.5415. The objective is to incorporate two existing seismic stations installed and currently operated by the Incorporated Research Institutions for Seismology (IRIS) into the Canadian National Seismograph Network (CNSN), where NRCan, through the Canadian Hazard Information Service (CHIS), would operate and maintain the stati...


Tectonic studies of the Rae craton and flanking orogenic systems
Principal Investigator: Thiessen, Eric
Licensed Year(s): 2023 2022
Summary: This licence has been issued for the scientific research application No.5403. This research will be guided by three objectives: 1) determine the largest possible contribution of mantle-derived heat sources; 2) establish a modern structural and tectono-metamorphic framework; and 3) evaluate evidence for mantle-derived heat input. Studies will involve field observations and targeted small-vol...


Tonian–Ediacaran Geobiology of the Mackenzie Mountains, NWT
Principal Investigator: Strauss, Justin Vincent
Licensed Year(s): 2023 2022
Summary: This licence has been issued for the scientific research application No.5409. This proposal aims to investigate three of the most intriguing questions of the Neoproterozoic Era (1000-541 million years ago, Ma) by performing a field-based examination of sedimentary rocks in the Mackenzie Mountains of Northwest Territories. These questions include: 1) what are the stratigraphic expressions and si...


Watershed-scale geomorphic response to climate change in the Aklavik Range, NWT
Principal Investigator: Strauss, Justin Vincent
Licensed Year(s): 2023 2022
Summary: This licence has been issued for the scientific research application No.5411. or this latest phase of research, the research team propose to integrate field observations, geochemical techniques, and historical remote sensing analysis to quantify the rates and processes by which sediment is generated from bedrock and transported downslope via hillslope and river processes under a changing climat...


Potential for large lakes to serve as climate refugia for cold-adapted plants
Principal Investigator: Nielsen, Scott
Licensed Year(s): 2023 2022
Summary: This licence has been issued for the scientific research application No.5407. The objective of this thesis is to quantify the extent of lake-mediated cooling and its effect on shoreline and inland plant species at varying scales. The principal investigator (PI) will establish a series of transects at large lakes in northern regions of Manitoba, Saskatchewan, Alberta, and the Northwest Terr...


Capitalizing on long-term experimental manipulations to understand and predict arctic terrestrial ecosystem responses to climate warming
Principal Investigator: Grogan, Paul
Licensed Year(s): 2022 2021 2019
Summary: The objectives of this research project are: 1) to determine the biogeochemical and ecological significance of our discovery that mesic tundra plant growth can be co-limited by nitrogen (N) and phosphorus (P); 2) to predict the likely impacts of not just climate change, but also declining caribou and other mammalian herbivory, on tundra deciduous and evergreen shrub abundances; and, 3) to evaluate...


Inuvik to Tuktoyaktuk Highway Metal Chemistry
Principal Investigator: Gammon, Paul R
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5369. The overall objective of the research is to eventually determine the environmental chemistry of the elevated metal concentrations, which will in turn determine the environmental risk that these measured concentrations pose (i.e. will answer, at least in part, the questions: do these sites require remediation, and in w...


Yellowknife Wetland Delineation Study and Great Slave Lake Monitoring
Principal Investigator: Brown, Jennifer M
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5336. The purpose of the Wetland Delineation Study is to define the flow paths of effluent from the treatment lagoon to Great Slave Lake and thereby inform sampling design of the Great Slave Lake Monitoring Program. The objectives of the Wetland Delineation are varied and, based on available documentation, we understand the...


Investigating the seasonality of subarctic lakes in a changing climate using satellite & field data
Principal Investigator: Kheyrollah Pour, Homa
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5335. This proposed research is directed at understanding the impact of current/future climate warming on subarctic lake ecosystems. The aim is to explore the relationship of seasonal lake ice growth/ablation and water quality across a wide range of lake characteristics (size, volume, productivity, catchment characteristics...
