Researchers and affiliation:-Kethra Campbell-Heaton; graduate student; Department of Geography, Environment and Geomatics, University of Ottawa, Canada-Denis Lacelle; professor, Department of Geography, Environment and Geomatics, University of Ottawa, Canada-Wayne Pollard; professor, Department of Geography, McGill University, CanadaWhat:Proposed is scientific research, to be carried out over 3-4 years. This project seeks to understand the impact thawing permafrost has on two watersheds in the high Arctic. This project's scale is small, as it will focus on two streams near the Eureka Weather Station. However, this project's results can be used to address the impacts of permafrost thaw on other high arctic watersheds. There are approximately three people involved in the project, with one to two participating in fieldwork. Planes will be the primary means of transport to and from Eureka, transportation will be arranged on a commercial aeroplane from Ottawa to Resolute. Then, from Resolute to Eureka a Twin Otter will be used, this is provided by PCSP.Why:The importance of this project is rooted in climate change research. Much of the circumpolar Arctic is experiencing rapid climate change; thus, northern communities are experiencing permafrost thaw firsthand. Thawing permafrost can alter a regions' water resources, increase surface flooding and cause terrain instability. This project aims to understand the impact climate-induced permafrost thaw has on two high Arctic watersheds. The long-term implications of permafrost thaw are unknown; as climate warming increases, we see a shift in the Arctic tree line, more flooding events, a thicker active layer and more carbon emissions. Therefore, it is more important than ever to study permafrost thaw in relation to water resources in the high Canadian Arctic. Where:This study location for this project is near the Eureka Weather Station, Nunavut. This area has the PEARL research station and a national defence base. This area is over 500km away from northern communities and protected areas.When:This is a multi-year project (2021-2024), with fieldwork occurring during the summer months (May-August).
