Understanding the cumulative impacts of beaver activity on stream health in the Inuvialuit Settlement Region
chercheur principal: Musetta-Lambert, Jordan
Année(s) de permis: 2024 2023
Résumé: This licence has been issued for the scientific research application No. 5641. The broad research question is: How will beaver activity in the tundra impact aquatic ecosystem health? This research project will answer this broad question by addressing the following specific objectives and questions: Generate an understanding of beaver activity impacts on aquatic food webs in tundra streams. Que...

Permafrost slumping and land-water connections on the Peel Plateau
chercheur principal: Tank, Suzanne E
Année(s) de permis: 2024 2023 2022 2021
Résumé: This licence has been issued for the scientific research application No.5249. 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 che...

Identifying sources of mercury in Arctic rivers
chercheur principal: Zdanowicz, Christian M
Année(s) de permis: 2019 2018
Résumé: The goal of this project is to identify and quantify (measure) the different possible sources of toxic mercury that is transported in rivers of the Mackenzie River basin, all the way down to the Beaufort Sea. In particular, the research team want to establish how much mercury comes from "modern" sources (like distant air pollution, runoff from rain/snow, wash-out from surface soils, etc.) and how ...
