Monitoring cumulative effects to water quality: An NWT Pilot Study - expanded to include aquatic invertebrates
chercheur principal: Chin, Krista
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No. 5647. The main objective of this research project is to further inform the story of how cumulative effects impact lake systems in the Yamba River basin. The research team intends to accomplish this by collecting benthic macroinvertebrates in 70 lakes in the Yamba River basin to compliment water quality data that were colle...


Impacts of Permafrost Thaw Slump Extent, Severity and Persistence on Stream Biotic Health
chercheur principal: Musetta-Lambert, Jordan
Année(s) de permis: 2023 2022
Résumé: This licence has been issued for the scientific research application No.5613. The project with investigate impacts of permafrost slumping on water quality, benthic macroinvertebrate communities, fish communities and ecosystem function by advancing research on thaw slumps within the Stony Creek Watershed. The research team will directly collaborate with the Northwest Territories Geological Surve...


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...


Northern Water Futures Baseline Environmental Monitoring
chercheur principal: Baltzer, Jennifer L
Année(s) de permis: 2021 2019 2018
Résumé: This licence has been issued for the scientific research application No.4983. The overall objective is to understand existing and potential impacts of climate change and resource development in the Sahtú region on four key aspects: 1) the landscape, 2) vegetation, 3) water resources, and 4) aquatic ecosystems. Specifically, the team seek to understand: a) terrain instability due to permafrost t...


A multidisciplinary investigation of recovery in Yellowknife area lakes from 50 years of arsenic pollution: What are the factors inhibiting recovery and the biological consequences?
chercheur principal: Palmer, Mike
Année(s) de permis: 2019 2018 2017
Résumé: The overarching objectives of this research are two-fold: 1)To investigate watershed and within-lake abiotic processes affecting the recovery of mine-impacted lakes in the Yellowknife area, including storage and release of arsenic from soils, seasonal dynamics of arsenic export in runoff, and fluxes of arsenic to and from lake sediments; and 2) To investigate the toxicological consequences of ...


Identification of hybrid copepods between C. finmarchicus and C. glacialis
chercheur principal: Maps, Frederic FM
Année(s) de permis: 2018
Résumé: Project aims to identify hybrid between C. finmarchicus and C. glacialis and to estimate the geographical distribution of the hybrids. Sample will be collected from a ring net, mesh size 200 micrometer (µm). The net will be deployed from the back of the boat. It will be towed vertically at a speed of 30 m/min. The samples collected will be sieve through 200 µm stainless steel mesh to separate w...


Further Examination of the Bio- Magnification of Mercury within Fish Species of the Deh Cho and their Varying Levels among Lakes
chercheur principal: Swanson, Heidi
Année(s) de permis: 2018 2017 2016 2016 2015 2014 2013
Résumé: 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; and, 3) to determine with fish have the lowest levels of mercury and the highest levels of nutrients. The methods for this project include field sampling, laboratory analysis, and data analysis and reporting. The resea...


Understanding the potential impact of metals in aquatic systems.
chercheur principal: McGeer, Jim
Année(s) de permis: 2017
Résumé: The objectives of this research are to evaluate the relative sensitivity of northern aquatic invertebrates and northern ecosystems in comparison to southern species and environments. The focus of comparisons is in relation to the toxicity of metals. Three types of sample collections are proposed. These would be done at selected sites along the Ingraham Trail (highway 4) east of Yellowknife. The...


A Coastal, Pan-Canadian Collection of Plants, Microalgae, and Marine Invertebrates for the Canadian Museum of Nature
chercheur principal: Graham, Mark S
Année(s) de permis: 2017
Résumé: The goal of this work is to assemble a representative collection of marine invertebrates, vascular plants, lichens, mosses, liverworts and aquatic, microscopic algae for research and educational purposes at the national museum (the Canadian Museum of Nature). Specimens will be used in ongoing research projects at the Canadian Museum of Nature, focused on the biodiversity of the vascular plant, lic...


Under The Pole - Innovative Underwater Exploration
chercheur principal: Bihan-Poudec, Anne-Claire
Année(s) de permis: 2017
Résumé: This survey aims at discovering bioluminescent and biofluorescent species in Polar Regions (namely the Arctic), assessing and understanding the potential functions of the phenomena. Marcel Koken and his team hope to discover bioluminescent or biofluorescent species in the Arctic mesophotic zone. As the mission consists of an exploration of an under-studied part of the ocean, the scientific team...
