Impacts of wildfire on runoff response and downstream water chemistry in a region with rapid permafrost loss
Principal Investigator: Olefeldt, David
Licensed Year(s): 2024
Summary: 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
Principal Investigator: Olefeldt, David
Licensed Year(s): 2023 2022 2021
Summary: 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 ...

Further Examination of the Bio- Magnification of Mercury within Fish Species and watersheds of the Deh Cho and Their Varying Levels Among Lakes
Principal Investigator: Low, Mike
Licensed Year(s): 2024 2023 2021 2019
Summary: This licence has been issued for the scientific research application No.5348. The objectives of this research project are: 1) to determine why fish mercury levels vary among lakes in the Dehcho region; 2) to identify best predictors of fish mercury levels; 3) to determine with fish have the lowest levels of mercury and the highest levels of nutrients; and, 4) to collect data on parameters that ...

Contaminant Biomonitoring in the Northwest Territories Mackenzie Valley: Investigating the Links Between Contaminant Exposure, Nutritional Status, and Country Food Use
Principal Investigator: Laird, Brian D
Licensed Year(s): 2018 2016
Summary: The overall objective of this research is to promote country foods in the Dehcho Region in a way that balances contaminant risks and nutrient benefits in order to maximize nutrient status while minimizing mercury exposure. The research team will work towards this objective through the implementation of research that will consist of the biomonitoring study to evaluate country food usage patterns, c...

Updating data on mercury levels in food fish species in lakes used by Deh Cho communities
Principal Investigator: Low, George
Licensed Year(s): 2016 2015 2014 2012 2011
Summary: The objectives of this project are: 1) to determine through which lakes are important as food sources in four Dehcho communities and which fish species are used for human food from these lakes; 2) to train community monitors to collect fish and other samples according to Environment Canada and Department of Fisheries and Oceans protocol; 3) to involve local school children in the studies by ...

Investigation of factors affecting high mercury levels in fish in lakes in the Mackenzie River Basin (2002-2003)
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2003 1998
Summary: This study is based on earlier research conducted by the Department of Fisheries and Oceans which found that fish in many lakes in the Mackenzie River Basin had high mercury concentrations. This study examines the environment in which the fish live in o...
