THAWPOND-NWT – Remote sensing analysis of vegetation and thaw pond colour dynamics in the continuous permafrost zone: from local to regional (Northwest Territories, Arctic Canada)
Principal Investigator: Vieira, Gonçalo
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5639. The goal of this research project is to better understand the characteristics of various different lakes, how their characteristics vary, as well as their potential relation to permafrost thaw events in the recent or distant past. The frequency of occurrence across space and time as well as the variability of: 1) opt...


Hydrothermal Regime of Riparian Terrain in Continuous Permafrost, Western Canadian Arctic
Principal Investigator: Ensom, Timothy P
Licensed Year(s): 2022 2021 2020 2019 2018 2017
Summary: This licence has been issued for the scientific research application No.5168. The specific objectives of the project are as follows: 1) Determine the spatial extent, distribution, and timing of winter icing events in streams along the Inuvik to Tuktoyaktuk Highway (ITH) through ground-based and aerial reconnaissance of stream crossings; 2) Identify relations between physical watershed charact...


Understanding the impacts of permafrost thaw on water resources and hydrology in the Dehcho region.
Principal Investigator: Quinton, William L.
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5120. The long-term objective of this research program is to improve the understanding, parameterisation and prediction of water flow and storage processes in peatland-dominated, thawing, discontinuous permafrost. Over the next 5 years, significant progress toward this long term objective will be made through the following ...


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...


Permafrost in the western Arctic
Principal Investigator: Kokelj, Steve V
Licensed Year(s): 2020 2019 2018 2017 2016
Summary: This licence has been issued for the scientific research application No.4663. The primary objectives of this research are: 1) to develop and test new methods of monitoring permafrost landscape change; 2) to investigate the impacts of natural and human disturbance on permafrost terrain and the ground temperature conditions in natural environments and in communities; and 3) to assess the physical...


A Mass-Energy Analysis of Permafrost and Vegetation Change Across a Mackenzie Mountain Treeline Ecotone: 1944 to 2017
Principal Investigator: Kershaw, Geoffrey GL
Licensed Year(s): 2020 2019 2018 2017
Summary: The goal of this thesis is to characterize the hydrology of an alpine valley's landscape Types (LTs) and how they affect storage and runoff responses to precipitation through the following four research objectives: 1) a physical description of LTs composing an alpine study catchment that are expected to exhibit distinct hydrological responses to precipitation inputs; 2) a physical description of w...


The effect of permafrost slumping on carbon delivery from land to water
Principal Investigator: Tank, Suzanne E
Licensed Year(s): 2019 2018 2017 2016 2015 2014
Summary: The objective of this study is to understand how permafrost slumping increases the mobilization of carbon from land to water, and the effects of this transport on stream ecosystems and the global carbon cycle. This summer, the research team will measure streamwater chemistry at a series of sites draining from the Peel Plateau, near where they enter the Mackenzie Delta. At one site (Stony Creek), t...


Remote sensing of Arctic-Boreal surface water
Principal Investigator: Smith, Laurence C.
Licensed Year(s): 2017
Summary: The goal of this project is to measure variations in water surface elevation, inundation extent, permafrost presence/absence, active layer thickness, soil moisture and related variables for lakes, wetlands and rivers in four primary study areas within the Northwest Territories (NWT). Using ground measurements combined with maps of water surface elevation produced by the Air Surface Water and Ocean...


The effects of wildfire on diverse aquatic ecosystems of the NWT
Principal Investigator: Tank, Suzanne E
Licensed Year(s): 2017 2016
Summary: The objective of this study is to determine the effect of fire on water quality within the southern NWT landscape. The research team will work across the Taiga Plains and Taiga Shield ecoregions. Differences in landscape between these regions will affect the catchment response to fire. The team will also target catchments with variable permafrost extent, and wetland/lake coverage. The research ...


Investigations of the water cycle and hydrological processes of the subarctic Canadian Shield
Principal Investigator: Spence, Christopher
Licensed Year(s): 2017 2016 2012 2011 2010 2009 2008 2007
Summary: It is the objective of this research to determine the water cycle processes acting in watersheds that could affect the streamflow response and water chemistry of Taiga Shield streams. The proposed work will take place within a research basin framework. The proposed watershed, the upper reaches of Baker Creek, is a typical Canadian Shield stream that drains 150 km2 into Great Slave Lake. There ...
