East Arm basin targeted bedrock mapping project
Principal Investigator: Canam, Rebecca
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5175. The main research objective of this project is to conduct targeted bedrock mapping and supporting analytical work to improve our understanding of the tectonic framework of the East Arm basin. The research team aims to document the timing of crystallization and metamorphism of the basement rocks onto which the East Arm...


Nutrient and contaminant status in the wetlands of the Slave River Delta
Principal Investigator: Doig, Lorne
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4988. The objectives of this project are to determine: 1) From the outer Slave River Delta (SRD) (river-water dominated) to the apex of the SRD (runoff dominated), what the current status of nutrients and contaminants in SRD wetland ecosystems are; 2) How trace elements (e.g., mercury) move through SRD wetland food webs; an...


Sources and fate of microplastics in Great Slave Lake
Principal Investigator: Bourdages, Madelaine
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5004. The first objective of this project is to quantify microplastic concentration and composition in water, sediment, zooplankton, and air around Great Slave Lake. The second objective of this project is to examine if microplastic concentrations are greater near communities than the open water of Great Slave Lake. The thi...


Bioavailability and toxicity of heavy metals in the Slave River Delta, NWT
Principal Investigator: Stone, Michael
Licensed Year(s): 2004
Summary: Currently, there is no information about the bioavailability and toxicity of metals in the Slave River delta. The goal of this research is to examine metal cycling pathways in the delta and to assess the role of aquatic vegetation for metal accumulation...


Use of Ground Penetrating Radar to Assess Subsurface Sediments in the Fort Smith, Slave, Hay River and Liard Deltas
Principal Investigator: Jol, Harry M.
Licensed Year(s): 1992 1991 1990
Summary: Surveys will be conducted on the surface of the delta plains. A Pulse Ekko IV ground penetrating radar system will be used to take measurements every 1 to 2 metres using this portable system. These waves due to their frequency (50 to 200 MHz) have no affect on the environment (they are similar to FM radio waves)....


Influence of the Slave River on Great Slave Lake
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 1992
Summary: The Researchers will collect a series of sediment and water samples. These will be analyzed for plant nutrients, concentration of microscopic plant cells, bacteria, suspended solids, dissolved oxygen and organic contaminants. Microscopic animals will also be netted. They will determine the abundance and composition of the animals and conduct experiments to measure their feeding rates and fat cont...
