Wetland status, change, and seasonal inundation dynamics for assessing the vulnerability of waterfowl habitat within the ABoVE study domain
Principal Investigator: French, Nancy H
Licensed Year(s): 2020 2019
Summary: This licence has been issued for the scientific research application No.4624. The main project goal is to characterize changes in waterfowl habitat using remote sensing approaches developed during prior NASA ABoVE research campaigns. The first objective is to create wetland type and surface inundation products (maps) for the ABoVE boreal region. The second objective is to assess the efficacy of...


Deglaciation of the NW Laurentide Ice Sheet and opening of the Mackenzie valley
Principal Investigator: Froese, Duane G
Licensed Year(s): 2020 2019 2018
Summary: This licence has been issued for the scientific research application No.4490. In this project, the research team aim to improve the chronology of the retreat of the Laurentide Ice Sheet from the eastern foot of the Mackenzie Mountains and the Mackenzie River valley that began around 14,000 years ago, and to gain better understanding of the dynamics of how the ice left the region and development...


Radar Satellite Observations of Lake Ice Breakup and Freeze-up
Principal Investigator: Drouin, Hugo
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4588. 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 ...


Transitioning of permafrost to wetland and implications for biomass gains and losses
Principal Investigator: Chasmer, Laura E
Licensed Year(s): 2019
Summary: 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
Principal Investigator: Miller, Charles E
Licensed Year(s): 2019
Summary: 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
Principal Investigator: Miller, Charles E
Licensed Year(s): 2019 2018 2017
Summary: 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...


From Archaea to the Atmosphere: Integrating Microbial, Isotopic and Landscape-Scale Observations to Quantify Methane Emissions from Global High-Latitude Ecosystems
Principal Investigator: Varner, Ruth K
Licensed Year(s): 2019
Summary: The aim of this project is to combine remote sensing data, field measurements and biogeochemical modeling to improve methane emissions estimates from thawing permafrost peatland landscapes at local, regional and global scales. To accomplish this, the research team will integrate data on water table and vegetation from remote sensing (satellites, unmanned aerial vehicle (UAVs)), with local measurem...


Understanding the Interactions between Wildfire Disturbance, Landscape Hydrology and Post-Fire Recovery in Boreal-Taiga Ecosystems
Principal Investigator: Bourgeau-Chavez, Laura L.
Licensed Year(s): 2019
Summary: The overall goal of the research is to improve understanding of the controls and impacts of a changing climate on the vulnerability and resiliency of boreal-taiga ecosystems to wildfire. This is being addressed through field sampling and process-based ecological and hydrological modeling of the 2014-2016 wildfires of southern NWT. To conduct the proposed research, the research team will addres...


Remotely Piloted Aircraft Based Research
Principal Investigator: Rogers, Marty W
Licensed Year(s): 2019
Summary: The goal of this project are to safely collect high-resolution images utilizing remotely piloted aircraft, producing image products to allow for a better understanding of the road infrastructure and nearby habitat, and of the Beluga Whale population in the near-shore Tarium Niryutait Marine Protected Area. Remotely Piloted Aircraft Systems (RPAS), based at Inuvik Airport will be used to fly abo...


Beaufort Sea Coastal Restoration – Exploring the Potential for Using Indigenous Plant Species to Revegetate Coastline Affected by Permafrost Thaw Slumping
Principal Investigator: Hille, Erika C
Licensed Year(s): 2019 2018
Summary: 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 runoff to the Beaufort Sea; 4) examining the effects of coastal erosion and thaw ...
