Fluxes from Land to Ocean: How Coastal Habitats in the Arctic Respond (FLO CHAR)
chercheur principal: Juhls, Bennet
Année(s) de permis: 2024 2023
Résumé: This licence has been issued for the scientific research application No. 5841. The overall objective of this project is to determine the impact of changing land-ocean matter fluxes and coastal subsea permafrost on nearshore ecosystems and biodiversity in the Beaufort Sea. To reveal the trajectory of coastal habitats, it is critical to (1) determine how fluvial and coastal fluxes from the land...


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...


Measuring surface displacement using winter SAR
chercheur principal: Rabus, Bernhard
Année(s) de permis: 2023 2022
Résumé: This licence has been issued for the scientific research application No. 5676. The objective of this research is to determine: 1) the accuracy of existing physical models of the Interferometric synthetic-aperture radar (InSAR) dry snow signal; 2) if the snow signature can be removed to enable accurate measurement of heave from winter refreezing in the active layer. There are currently three ...


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 ...


Drivers and constraints of ecological change in the western Arctic
chercheur principal: Lantz, Trevor C.
Année(s) de permis: 2022 2021 2019 2018 2017
Résumé: This licence has been issued for the scientific research application No.5277. The objectives of this research are: 1) Use remote sensing (Landsat, QuickBird, InSAR, Airphotos, UAVs, etc.) to document regional landscape change (tundra fire, infrastructure, saline flooding, slumps, subsidence, vegetation change, lake drainage / expansion, etc.); and 2) Use field sampling and monitoring to determi...


Remote Sensing and Geophysics of Tundra Landscapes
chercheur principal: Ullmann, Tobias
Année(s) de permis: 2022
Résumé: This licence has been issued for the scientific research application No.5193. The research team will investigate the possibility of linking field-measured characteristics of tundra landscapes (e.g. active layer thickness, soil moisture, plant distribution and ecosystem composition, etc.) with remotely-sensed data. The overall objective of the project is to identify the connection that exist bet...


Beaufort Sea Coastal Restoration – Exploring the Potential for Using Indigenous Plant Species to Revegetate Coastline Affected by Permafrost Thaw Slumping
chercheur principal: Hille, Erika C
Année(s) de permis: 2021 2021 2020 2019 2018
Résumé: 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
chercheur principal: Kokelj, Steve V
Année(s) de permis: 2020 2019 2018 2017 2016
Résumé: 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...


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'...
