Improved measurements of Arctic snowfall using a novel interdisciplinary approach (A-Snow) - Atmospheric science component
chercheur principal: Thériault, Julie Mireille
Année(s) de permis: 2024
Résumé: This licence has been issued for the scientific research application No. 5743. The objective of this proposal is to develop a next-generation method to accurately measure Arctic snowfall under a range of environmental conditions typical across the Arctic. The specific objectives are: 1) Measure key snowfall parameters using state-of-the-art instruments as required to estimate snowfall during t...


GMOB: Remediation Strategies for the Long-term Management of Arsenic-trioxide-bearing Roaster Wastes at the Giant Mine, Northwest Territories
chercheur principal: Blowes, David W.
Année(s) de permis: 2024 2023 2022 2021
Résumé: This licence has been issued for the scientific research application No. 5779. The overall goals of the four projects proposed within Phase 1 are to: 1. Provide an enhanced understanding of the physical and geochemical properties of the roaster waste 2. Screen for potentially viable remediation alternatives that may warrant additional research (e.g., long-term laboratory experiments, pilot-s...


Three-Dimensional multi-methodological Investigation of Retrogressive Thaw Slumps in the Mackenzie Delta region (3DIRTS)
chercheur principal: Kunz, Julius
Année(s) de permis: 2023
Résumé: 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...


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)
chercheur principal: Vieira, Gonçalo
Année(s) de permis: 2023
Résumé: 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...


Impacts of climate change on fire fuels in wetlands and forested areas
chercheur principal: Chasmer, Laura E
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No. 5614. The objectives for this research licence are to compare the fuel characteristics within accessible areas in the Fort Simpson area to collected lidar remote sensing, to develop an ecozone specific fire fuel model; to determine how fire fuels have changed within northern latitudes over time and compare them to the chan...


Permafrost and ground hazard mapping between Norman Wells and Wrigley along the Mackenzie Valley winter road using airborne geophysics
chercheur principal: Froese, Duane G
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No. 5160. The research team will use airborne geophysics (helicopter-based surveys) flying the central Mackenzie Valley corridor along the existing winter road to map permafrost across different landforms and terrain types. The objectives of this study are to: 1) Fly multiple lines of airborne electromagnetic geophysical data ...


Multi-methodological three-dimensional investigation of open- and closed-system Pingos in northwestern Canada (Pingo3D)
chercheur principal: Kneisel, Christof
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No. 5654. This research project aims to investigate the three-dimensional internal structure of pingos in the Mackenzie Delta Region. The focus is on small-scale heterogeneities and a detailed delineation of ice-rich or unfrozen areas within, underneath and in close proximity to different pingos. High-resolution, three-dimensi...


Quantification of carbon fluxes and ecosystem characteristics in permafrost regions with a special focus on the impact of degradation processes
chercheur principal: Goeckede, Mathias
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No. 5609. As part of the ERC-synergy project Q-Arctic, the research team plans to investigate biogeochemical and biogeophysical processes along transects following landscape gradients. Such gradients include natural variability within heterogeneous permafrost landscapes, such as: a transect from dry upload tundra into a lower ...


NASA Arctic-Boreal Vulnerability Experiment (ABoVE) Airborne Flights 2023
chercheur principal: Miller, Charles E
Année(s) de permis: 2024 2023
Résumé: This licence has been issued for the scientific research application No. 5601. From 2017 – 2022, ABoVE airborne teams collected data across a wide variety of ecosystems in both the US and Canada. Depending on available funds, the team may re-fly one of the sensors to collect hyperspectral data at several locations in 2023. For 2023, the NASA Dynamic Aviation King Air B-200 aircraft with a h...


Capitalizing on long-term experimental manipulations to understand and predict arctic terrestrial ecosystem responses to climate warming
chercheur principal: Grogan, Paul
Année(s) de permis: 2024 2023 2022 2021 2019
Résumé: This licence has been issued for the scientific research application No. 5660. The objectives of this research project are: 1) To determine the biogeochemical and ecological significance of the discovery that mesic tundra plant growth can be co-limited by nitrogen and phosphorus. 2) To predict the likely impacts of not just climate change, but also declining caribou and other mammalian herbivor...
