Remote Sensing and Geophysics of Tundra Landscapes
chercheur principal:
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...


Characterizing the sensitivity and response of freshwater systems to permafrost thaw in the Western Canadian arctic
chercheur principal:
Année(s) de permis: 2021 2021 2020 2019 2018
Résumé: This licence has been issued for the scientific research application No.4934. The purpose of this study is to develop a method of characterizing the sensitivity and response of streams and rivers to regional variability in permafrost thaw in the Beaufort Delta Region, Western Canadian Arctic. All of the field team members are from within the NWT. This field program will follow the attached E...


Hydrothermal Regime of Riparian Terrain in Continuous Permafrost, Western Canadian Arctic
chercheur principal:
Année(s) de permis: 2022 2021 2020 2019 2018 2017
Résumé: This licence has been issued for the scientific research application No.4938. 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 ITH through ground-based and aerial reconnaissance of stream crossings; 2) Identify relations between physical watershed characteristics and icing dynamics thro...


Permafrost in the western Arctic
chercheur principal:
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...


Radar Satellite Observations of Lake Ice Breakup and Freeze-up
chercheur principal:
Année(s) de permis: 2020 2019
Résumé: This licence has been issued for the scientific research application No.4648. This project aims to evaluate and develop the utility of Canada’s future RADARSAT Constellation Mission (RCM) (launch June 2019) for the monitoring of lake ice breakup and freeze-up. RCM-type radar images will be simulated using data from Canada’s current radar satellite – that is - RADARSAT-2. Validation data in the ...


ABoVE Permafrost Dynamics Observatory
chercheur principal:
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'...


NASA ABoVE Airborne Campaign 2019
chercheur principal:
Année(s) de permis: 2019 2018 2017
Résumé: This licence has been issued for the scientific research application No.4499. This airborne field campaign will link studies conducted on the ground with data collected through satellite remote sensing, enabling a deeper understanding of the vulnerability and resilience of these ecosystems, and how people within and beyond this region are responding to change. The ABoVE airborne campaigns can p...


Forest Ecotone Experiment
chercheur principal:
Année(s) de permis: 2019 2018 2017
Résumé: The overarching objective of the study is to integrate light detection and ranging (LiDAR), passive spectral, and tree ecophysiological data to link biophysical structure to ecological function in the Forest Tundra Ecotone. In so doing, the research team will be able to remotely assess the vulnerability and resilience of the forest tundra ecotone (FTE) to environmental change. The field work wi...


PermASAR - Airborne SAR campaign on permafrost soils and boreal forests in the Canadian North-West
chercheur principal:
Année(s) de permis: 2019 2018
Résumé: For this project the research team will conduct the collection of microwave radar backscatter data of permafrost and boreal forest at wavelengths of 3cm (X-band), 6cm (C-band), 10cm (S-band) and 23cm (L-band). This process will capture two stable permafrost active layer states: thawed and frozen. The research team will derive information about permafrost (e.g. soil status, soil moisture) and about...


Remote Sensing and Geophysics of Tundra Landscapes
chercheur principal:
Année(s) de permis: 2019 2018
Résumé: The proposed project 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 connections that exist between observable surface properties and their associated subsurface/permafros...
