Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No.5558. The goal of this project is to design and maintain a long-term, locally-based, diet and condition data collection program focused on ringed seals (Pusa hispida) and bearded seals (Erignathus barbatus) in the Darnley Bay, Sachs Harbour, and Ulukhaktok areas of the Inuvialuit Settlement Region, NT. To accomplish the ...

Summary: This licence has been issued for the scientific research application No. 5635. The objectives are: To establish the patterns of occupancy of beavers along the Inuvik-Tuk highway. To establish the patterns of past occupancy of beavers along the Inuvik-Tuk highway. To coproduce monitoring methods for ongoing beaver monitoring and research with community researchers. To develop methods for ide...

Summary: This licence has been issued for the scientific research application No. 5640. Objectives: To address changing beaver population and the impacts on lakes and streams, fish and communities and wellbeing, including: a) research with communities to develop an approach for mapping beaver occupancy using photo, video and drones b) research in to the impacts of beavers on people c) research in...

Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5471. The objectives of this research project are to: 1. Characterize the effects that chemical extracts from the traditional food samples have on a number of cellular processes. Their results can indicate the type of toxicity that those chemical extracts may cause. 2. Use the Arctic beluga as a "clean" reference in inves...

Summary: This licence has been issued for the scientific research application No.5342. The objectives of this project are to document Inuit knowledge and observations of Arctic char and Greenland cod movement ecology and health. The research team will co-produce knowledge among Inuit and scientists to better understand changes in Arctic char and Greenland cod and fisheries. The team will examine if and ...

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...

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...

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...

Licensed Year(s): 2015
Summary: Thaw slumps are one of the most dramatic thermokarst features in permafrost regions. The number of thaw slumps on Banks Island has more than tripled in recent decades and it is likely that this change is altering terrestrial and aquatic ecosystems. This multidisciplinary research project investigates the short- (1960s-present day) and long-term (Medieval Warm Period to today) impacts of permafrost...

Summary: This study will examine the effects of permafrost and flooding on the ecological structure and carbon exchange of contrasting lakes in the Mackenzie River Delta. Patterned ground marked by ice-wedge polygons is formed by freezing and thawing of the soil, which forms cracks into which ice can spread and cause the soil to uplift. These processes have effects on the hydrology and water chemistry of a...
