The impact of permafrost thaw on Taiga Shield and Taiga Plains lakes
Principal Investigator: Palmer, Mike
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5974. The specific research objectives are: 1) to implement a geologically-based classification scheme to group permafrost lake types for the range of biophysical environments encountered across the NWT; and 2) to determine whether these lake types can be distinguished by their physical and water chemistry characteristics....


Enhanced Characterization of Groundwater Flow Phenomena Within Discontinuous Permafrost Terrain in the Central Mackenzie
Principal Investigator: Rudolph, David
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5990. The main objective of the proposed research is to continue investigating the groundwater flow conditions within the Central Mackenzie Valley of the Northwest Territories (NWT), with a specific focus on how permafrost discontinuity and thaw processes will influence groundwater circulation and interaction with surface...


The water quality response of Arctic rivers to regional variability in landscape and permafrost conditions
Principal Investigator: Hille, Erika C
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No. 5596. The objectives of this study are to conduct spatially detailed surveys of water quality and stream discharge along the Miner River, in order to examine how water quality responds to organic-rich peatland tributary streams and retrogressive thaw slumping; and, to examine the seasonal water quality of Caribou Creek and...


How are changes on the land affecting water resources around Fort Good Hope and Ts’ude Niline Tuyeta?
Principal Investigator: Comte, Jerome
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5930. This project proposes to evaluate responses of aquatic ecosystems to permafrost thaw, lake drying, and wildfire, as well as their cumulative impacts. Lake chemistry and biological diversity (microbes and invertebrates) in water (current environmental change) and in sediments (historical change) will be characterized,...


Impacts of wildfire on runoff response and downstream water chemistry in a region with rapid permafrost loss
Principal Investigator: Olefeldt, David
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5892. Objective summary: To assess the effect of wildfires on changes in water quality in the Dehcho and South Slave region, which are affected by runoff from peatlands (containing e.g., organics, nutrients, and mercury/methylmercury), which are already experiencing increased permafrost thaw due to climate change. Synop...


The frontline of permafrost thaw: a transect of eddy covariance towers across the southern Taiga Plains to better understand changing regional carbon and water budgets
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2024 2023 2022 2021 2019 2018 2018 2017 2016 2015
Summary: This licence has been issued for the scientific research application No. 5890. Through this project my research group will address the following objectives: What is the net effect of permafrost thawing induced biophysical and biogeochemical feedbacks to the climate system? How do these two types of feedback differ between the sporadic and discontinuous permafrost zones? Is the reported decrease...


Studies of greenhouse gas release and associated environmental processes with thawing permafrost in the Inuvialuit Settlement Region
Principal Investigator: Morse, Peter D
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5797. The goals of this multi-year-long project are to assess greenhouse gas (methane and carbon dioxide) release from warming permafrost and tundra lakes in the ISR and to study associated carbon dynamics and microbiological processes, including the release of mercury to the environment. The first year of field activit...


Jean Marie River First Nation Climate Change Adaptation
Principal Investigator: Latta, Alex
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No. 5803. The objective of the proposed research is to support a climate change adaptation planning process in Jean Marie River, NWT. Simultaneously, it addresses the related objectives of two funded research projects: the Dehcho Collaborative on Permafrost (ArcticNet) and Advancing Indigenous Environmental Stewardship (SSHRC)...


North Slave Permafrost Study: Characterization and Predicting Discontinuous Permafrost for Climate Change Adaptation
Principal Investigator: Wolfe, Stephen A
Licensed Year(s): 2024 2023 2022 2021 2020
Summary: This licence has been issued for the scientific research application No. 5775. This activity describes and predicts the occurrence of discontinuous permafrost in the northern Great Slave Lake region to assist in planning, development and maintenance of community and industry infrastructure. Changes in climate are affecting permafrost distribution, temperatures and geotechnical conditions. Diffe...


Long-term ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT
Principal Investigator: Mamet, Steven D
Licensed Year(s): 2023 2022 2021 2020 2019
Summary: This licence has been issued for the scientific research application No. 5659. The objectives of this research project are to determine: 1) the status of permafrost landforms; 2) the circumstances surrounding long-term recovery after abandonment of the CANOL No. 1 project, including oil spills and gravel pits; 3) the status of treeline. Sampling and testing will consist of: 1) permafrost: th...
