How does proximity to roadways impact water quality and invertebrates in Arctic lakes?
chercheur principal: Gray, Derek K
Année(s) de permis: 2021
Résumé: This licence has been issued for the scientific research application No.4966. The purpose of the proposed project is to improve the understanding of the effects of road development on lakes in Canada’s north. To achieve this purpose, the research team will pursue two objectives: 1) to determine if changes in water quality caused by road dust affects invertebrate communities (bugs and waterfleas...


A monitoring program for Frame Lake
chercheur principal: Gray, Derek K
Année(s) de permis: 2020 2019
Résumé: We are planning to establish a long-term monitoring program in Frame Lake to monitor water quality, zooplankton, and benthic Invertebrates. Water quality probes will be set up at a central monitoring point on the lake. A buoy will be anchored to the lake bottom and the probes will be attached to the buoy. The probes will monitor temperature, dissolved oxygen, pH, and conductivity levels near th...


How will fish communities in Gwich’in and Inuvialuit lakes respond to climate change?
chercheur principal: Gray, Derek K
Année(s) de permis: 2019 2018 2017
Résumé: The purpose of this project is to obtain baseline data for fish communities in Gwich’in Settlement Area (GSA) and Inuvialuit Settlement Region (ISR) lakes and use these data to predict future changes in fish communities caused by climate change. Specific objectives are: 1) to develop a baseline data set for fish populations, fish habitat, water quality, and water temperature for small and m...


Impact of ferry landings on water quality and traditional fish harvesting in the Mackenzie and Peel Rivers
chercheur principal: Gray, Derek K
Année(s) de permis: 2019 2018
Résumé: Fishing is an important part of the Gwich’in way of life. Concerns in the Gwich’in communities of Fort McPherson and Tsiigehtchic have arisen with regards to the use of granular material in ferry landings. Anthropogenic sediment from ferry landings has the potential to alter river ecology downstream thus impacting valuable fish habitat. The objectives of this research project are to determine ...
