Mechanical and thermal design of embankments built on permafrost
Principal Investigator: Doré, Guy
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4562. 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 ...


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): 2019 2018
Summary: 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 runoff to the Beaufort Sea; 4) examining the effects of coastal erosion and thaw ...


Climate change impacts on lake ecosystems of the western Canadian Arctic
Principal Investigator: Korosi, Jennifer B
Licensed Year(s): 2019
Summary: The objectives of this research is to: 1) determine if thaw slumping results in the loss of a large-bodied zooplankton species (Daphnia) from lakes; and 2) measure polychlorinated biphenyl concentrations in lake sediments near the Distant Early Warning Line site in Tuktoyaktuk, to assess whether legacy contamination is still evident. The research team will be collecting sediment cores from ...

Hydrological Remote Sensing
Principal Investigator: Berg, Aaron A
Licensed Year(s): 2018 2017 2016
Summary: Our research has three main objectives: 1. to monitor the spatial variability of soil moisture at approximately a 10km resolution in the region of Trail Valley Creek (TVC); 2. to test the soil moisture retrieval algorithms in high organic soils through both satellite based measurements; and, 3. to measure and model the mass wasting at retrogressive thaw slumps as a function of debris thickness...


Correlation of water quality parameters of a disturbed slump and an undisturbed river bank on the east branch of the Mackenzie River.
Principal Investigator: Hansen, Jeremy R
Licensed Year(s): 2017
Summary: The objective is to investigate a disturbed slump site and an undisturbed river bank to measure and compare what is possibly melting/flowing/leaching into the river system possibly due to climate change. Physical descriptions of both sites combined with temperature, potential of hydrogen (pH), TSS (total suspended solids), TDS (total dissolved solids), and turbidity will be collected, analysed, an...


Effects of Climate Change and Landscape Perturbation on Arctic Tundra Lake Water Quality
Principal Investigator: Droppo, Ian G
Licensed Year(s): 2017
Summary: The overall goal of this study is to obtain information, through laboratory experiments (rainfall simulator; 2m annular flume) on sediments collected from retrogressive permafrost thaw shoreline slumps affecting numerous Arctic tundra lakes in the Mackenzie Upland Region east of the Mackenzie Delta, on the physical processes through which slump material is transported and delivered to a receiving ...
