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...


Mapping, monitoring and modelling permafrost change in the NWT
Principal Investigator: Kokelj, Steve V
Licensed Year(s): 2024 2023 2022 2021
Summary: This licence has been issued for the scientific research application No.5473. The primary objectives of this research are: 1) to develop and test new methods of characterizing permafrost and monitoring permafrost landscape change with a focus on the Beaufort Delta, central Mackenzie Valley and North Slave regions; 2) mapping sensitive permafrost terrain across NWT by integrating expert assessme...


Characterization of recent permafrost landslides and ground ice distribution in the central Mackenzie Valley, NWT
Principal Investigator: Froese, Duane G
Licensed Year(s): 2023 2022 2021
Summary: This licence has been issued for the scientific research application No.5423. This work builds on studies over the last several years, including field work in the Mackenzie River valley in 2018 and 2019. The objective of 2021 fieldwork is twofold: 1) characterizing a large suite of retrogressive thaw slumps and thaw-induced landslides in the Redstone, Keele, and Johnson River basins that have i...


Impacts of Permafrost Thaw Slump Extent, Severity and Persistence on Stream Biotic Health
Principal Investigator: Musetta-Lambert, Jordan
Licensed Year(s): 2023 2022
Summary: This licence has been issued for the scientific research application No.5324. The project with investigate impacts of permafrost slumping on water quality, benthic macroinvertebrate communities, fish communities and ecosystem function by advancing research on thaw slumps within the Stony Creek Watershed. The research team will directly collaborate with the Northwest Territories Geological Surve...


Beaufort Sea Coastal Restoration – Exploring the Potential for Using Indigenous Plant Species to Revegetate Coastline Affected by Permafrost Thaw Slumping
Principal Investigator: Hille, Erika C
Licensed Year(s): 2021 2021 2020 2019 2018
Summary: This licence has been issued for the scientific research application No.5057. The objectives include: 1) Creating a series of maps showing the thaw slump activity along the Beaufort Sea Coast near Tuktoyaktuk; 2) Developing detailed water, vegetation, and ground temperature maps of the study sites using drones; 3) Examining the effects of thaw slumping on the water quality of landscape-level r...


Trajectories of landscape change due to thawing permafrost
Principal Investigator: Korosi, Jennifer B
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4727. The research team will use lake sediment cores to track the history of shoreline permafrost thaw slump activity over the last several thousand years, and associated lake ecological responses to thaw slumping, in order to provide a long-term context for present-day observations. The team will select three pairs of ...


Permafrost thaw slumps, sediment dynamics and ecosystem health of upland tundra lakes within the western Canadian Arctic
Principal Investigator: Droppo, Ian
Licensed Year(s): 2020
Summary: This licence has been issued for the scientific research application No.4759. The overall objective of this research is to assess the permafrost thaw slump erosion and transport of its sediment by rainfall/runoff to depositional zones within Arctic tundra lakes. To achieve this, we will link a rainfall simulator with an annular flume (to simulate lake currents) located in the Hydro-ecology Moni...


Mechanical and thermal design of embankments built on permafrost
Principal Investigator: Doré, Guy
Licensed Year(s): 2020 2019
Summary: This licence has been issued for the scientific research application No.4629. The main objective is to develop a practical method for the mechanical and thermal design of embankments built on permafrost based on the properties of the active layer and of the permafrost as well as the loading conditions. The development of decision-making tools to select the optimal course and the optimal embankm...


Self-stabilization of thaw slumps
Principal Investigator: Doré, Guy
Licensed Year(s): 2019
Summary: The research team are studying the natural stabilization of thaw slumps in the aim to eventually develop adapted management strategies for infrastructure at risk. The specific objectives are to assess the variations of thaw slump stabilization across landscapes, regions, and climates; and to assess the positive and negative feedback effects controlling the natural stabilization of thaw slumps....


Impacts of Natural and Anthropogenic Disturbances on the Aquatic Health of Tundra Lakes in the Upland Region Northeast of Inuvik, NT
Principal Investigator: Hille, Erika C
Licensed Year(s): 2019
Summary: The objectives of this project are to examine the long term effects of thaw slumping on the water quality of water running off the landscape to the lakes and the lakes themselves, using data collected over the 10 year study period; and to examine the effects of tundra fire on the water quality of water running off the landscape to the lakes and the lakes themselves. This study will focus on 10 ...
