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...
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...

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 ...
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 ...

2022
2021201920182017 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...
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...

202020192018 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...

2020
2019201820172016 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...
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...
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'...
