Mapping, monitoring and modelling permafrost change in the NWT
chercheur principal: Kokelj, Steve V
Année(s) de permis: 2024 2023 2022 2021
Résumé: This licence has been issued for the scientific research application No. 5855. 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 ass...


North Slave Permafrost Study: Characterization and Predicting Discontinuous Permafrost for Climate Change Adaptation
chercheur principal: Wolfe, Stephen A
Année(s) de permis: 2024 2023 2022 2021 2020
Résumé: 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...


Impact of wildfire and forest management on permafrost and post-fire regeneration
chercheur principal: Baltzer, Jennifer L
Année(s) de permis: 2024 2023 2022 2021 2020 2019
Résumé: This licence has been issued for the scientific research application No.5543. This projects two main objectives are to monitor the recovery of NWT forests following wildfire to better understand post-fire changes on forest composition and ground vegetation and to develop baseline information about proposed forest management areas to support assessment of harvesting impacts on these areas. T...


Carbon sequestration in boreal forests during regeneration process after forest fire disturbances.
chercheur principal: Matsuura, Yojiro
Année(s) de permis: 2022
Résumé: This licence has been issued for the scientific research application No.5340. Main objective of the project is to re-start and maintain study sites after two growing season without any census and sample collections. The research team will also establish additional study sites for regeneration process and soil condition monitoring (detection of permafrost table depth). The team will try again to...


NASA Arctic-Boreal Vulnerability Experiment (ABoVE) Airborne Initiative 2022
chercheur principal: Miller, Charles E
Année(s) de permis: 2022
Résumé: This licence has been issued for the scientific research application No.5304. The extended ABoVE Study Area includes most of northwestern North America west of Hudson Bay and north and east of the coastal mountain ranges. It encompasses the variability in the key types of ecosystems that are both unique to arctic and boreal regions in North America as well as being representative of the larger ...


Hydrothermal Regime of Riparian Terrain in Continuous Permafrost, Western Canadian Arctic
chercheur principal: Ensom, Timothy P
Année(s) de permis: 2022 2021 2020 2019 2018 2017
Résumé: 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...


Impact of climate change on catchment biogeochemistry in plains and shield regions
chercheur principal: Olefeldt, David
Année(s) de permis: 2021 2019 2018
Résumé: This licence has been issued for the scientific research application No.4734. The objective of this research is to identify impacts of climate change and permafrost thaw on pond methane emissions, and on water chemistry in streams that drain peatland-rich catchments. Impacts on methane emissions will be assessed. Specific objectives are: 1) to characterize the trends and variability in magn...


Using the past to inform the future: A paleoecological perspective of the impacts of drought and fire on lakes, permafrost and forests
chercheur principal: Pisaric, Michael FJ
Année(s) de permis: 2019 2018 2017 2016
Résumé: This licence has been issued for the scientific research application No.4564. The objectives of this research are to examine the frequency and severity of past wildfire and drought (drought-like) conditions in the southern Northwest Territories. Specifically, the research team will examine the following questions: 1) how frequent and severe have fires been in the; 2) are fires becoming more fre...


Transitioning of permafrost to wetland and implications for biomass gains and losses
chercheur principal: Chasmer, Laura E
Année(s) de permis: 2019
Résumé: This licence has been issued for the scientific research application No.4527. The objectives are to: 1) Compare the distribution of tree and shrub biomass within accessible areas in the Taiga Shield and Taiga Plains landscapes using lidar remote sensing, and by developing tree and shrub vegetation biomass models from field data; 2) Characterize and compare non fire-disturbed patterns of veget...


ABoVE Permafrost Dynamics Observatory
chercheur principal: Miller, Charles E
Année(s) de permis: 2019
Résumé: The objective of this project is to collect physical and geophysical measurements quantifying permafrost susceptibility to ABoVE's internationally-available dataset. Researchers can access these data to bolster understanding of environmental processes and the ability to remotely-sense these on a regional scale. Airborne remote sensing missions from August 2017, 2018, and August of 2019 by NASA'...
