Impacts of wildfire on runoff response and downstream water chemistry in a region with rapid permafrost loss
chercheur principal: Olefeldt, David
Année(s) de permis: 2024
Résumé: This licence has been issued for the scientific research application No. 5892. Objective summary: To assess the effect of wildfires on changes in water quality in the Dehcho and South Slave region, which are affected by runoff from peatlands (containing e.g., organics, nutrients, and mercury/methylmercury), which are already experiencing increased permafrost thaw due to climate change. Synop...


Murky waters: Impacts of disturbances on the mobilization and downstream delivery of mercury and methylmercury
chercheur principal: Olefeldt, David
Année(s) de permis: 2023 2022 2021
Résumé: This licence has been issued for the scientific research application No.5448. This project proposes to monitor wetlands, streams, rivers, and lakes in the Dehcho region, with a focus on understanding current and future trends in aquatic mercury and methylmercury. The region has vast stores of mercury accumulated in organic wetland soils, and there is a risk that disturbances such as permafrost ...
