Principal Investigator: Somers, Gila L
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No.4762. Water Quality Monitoring equipment is deployed at over 40 sites across the NWT to address community concerns. Community members were trained to use the following equipment: • Sondes: sit in the water and measure basic water quality parameters every 2 hours for up to 3 months. Analysis undertaken at Environment and...

Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4823. The purpose of this work is to identify indicators of aquatic ecosystem health i.e., organisms such as bacteria, phytoplankton and invertebrates that are sensitive to environmental forces and play key role in aquatic food webs, to monitor and predict the response of aquatic ecosystems to environmental changes (e.g. pe...

Principal Investigator: Drygeese, Cody RJ
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4994. The goal of this project is to document existing environmental conditions surrounding the Project area. Studies may include the following. Hydrology studies include the measurement of selected lake inflow and outflow and stream profile through field surveys, and installation of data loggers to continually monitor l...

Principal Investigator: Lattaud, Julie
Licensed Year(s): 2020
Summary: This licence has been issued for the scientific research application No.4698. The project will study the dynamics of deltaic lake ecosystems over the past century through the application of recently developed molecular (lipid biomarker) and isotopic (radiocarbon and stable isotopes) proxies to lake sedimentary records. This will unravel the impact of old carbon input into aquatic ecosystems. Ra...

Summary: 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...

Summary: The objectives of our study are to 1) establish the importance of lake connectivity in determining the community composition and species richness of the invertebrate community of a lake, and the contribution of lakes of differing connectivity to the regional diversity of the Mackenzie Delta, 2) characterize the response of invertebrate communities to changing peak flood levels to allow prediction ...

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...

Summary: The objective of this study is to determine the effect of fire on water quality within the southern NWT landscape. The research team will work across the Taiga Plains and Taiga Shield ecoregions. Differences in landscape between these regions will affect the catchment response to fire. The team will also target catchments with variable permafrost extent, and wetland/lake coverage. The research ...

Summary: The objective is to describe the aquatic environment in the Yellowknife River between Bluefish Lake and Prosperous Lake as per the Fisheries Authorization and the Water Licence. This may include investigating aquatic vegetation, water quality and quantity, benthic invertebrates, fish and substrate. The results will be used to determine the most suitable means of fish habitat compensation or produc...

Summary: The project team intend to study carbon cycling in peatland catchments, in order to determine whether the interactions between wildfire and permafrost thaw causes increased release of greenhouse gases from peatlands and aquatic ecosystems to the atmosphere, and thus cause amplified climate change. Given the overall objective of the project, the team intend to address five research questions: ...
