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...


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): 2023
Summary: This licence has been issued for the scientific research application No. 5646. This project proposes to evaluate responses of aquatic ecosystems to permafrost thaw, lake drying, and wildfire, as well as their cumulative impacts. The researchers will characterize lake chemistry and biological diversity (microbes and invertebrates) in water (current environmental change) and in sediments (histori...


Three-Dimensional multi-methodological Investigation of Retrogressive Thaw Slumps in the Mackenzie Delta region (3DIRTS)
Principal Investigator: Kunz, Julius
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5655. This project aims to investigate the three-dimensional subsurface structures in the vicinity of active retrogressive thaw slumps and their relationship to spatio-temporal slump-development. The number and activity of retrogressive thaw slumps have increased during the last decades due to climatic, hydrologic and ther...


Effects of permafrost thaw and vegetation shifts on carbon and mercury cycling
Principal Investigator: Wild, Birgit
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5564. The main goal of the project is to understand how gradients in tundra vegetation and permafrost thaw affect soil carbon and mercury cycling. This will allow the research team to assess how permafrost thaw and changes in vegetation in a warmer climate could alter future carbon dioxide fluxes and impact mercury cycling ...


Perma-X Airborne Campaign 2023
Principal Investigator: Grosse, Guido
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5656. The objective is to conduct airborne surveys at 3300ft (1000m) altitude to collect high-resolution aerial images and LiDAR elevation data that can be used to describe and quantify rates of permafrost thaw, coastal erosion, thaw slumping, lake change, and vegetation change. Daily survey flights (depending on cloud-fre...
