A monitoring program for Frame Lake
Principal Investigator: Gray, Derek K
Licensed Year(s): 2019
Summary: 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?
Principal Investigator: Gray, Derek K
Licensed Year(s): 2019 2018 2017
Summary: 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
Principal Investigator: Gray, Derek K
Licensed Year(s): 2019 2018
Summary: 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 ...

Predicting climate-driven changes in water quality and biological communities in Gwich'in lakes
Principal Investigator: Gray, Derek K
Licensed Year(s): 2017
Summary: Zooplankton play a key role in aquatic food webs, providing a conduit for the movement of energy between primary producers (algae) and larger organisms such as macroinvertebrates and fish. Therefore, elucidating the impact of permafrost melting on zooplankton is key to gaining a broader understanding of climate change on aquatic ecosystems in Canada’s north. Objectives of this proposed researc...
