Principal Investigator: Vieira, Gonçalo
Licensed Year(s): 2023
Summary: 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...

Principal Investigator: Rabus, Bernhard
Licensed Year(s): 2023 2022
Summary: This licence has been issued for the scientific research application No.5270. The objective of this research is to determine the accuracy of existing physical models of the InSAR (Interferometric Synthetic Aperture Radar) dry snow signal; and, if the snow signature can be removed to enable accurate measurement of heave from winter refreezing in the active layer. There are currently three res...

Principal Investigator: Miller, Charles E
Licensed Year(s): 2022
Summary: 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 ...

Principal Investigator: Ullmann, Tobias
Licensed Year(s): 2022
Summary: 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...

Licensed Year(s): 2021 2021 2020 2019 2018
Summary: 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...

Licensed Year(s): 2020 2019 2018 2017 2016
Summary: 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...

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'...

Principal Investigator: Hajnsek, Irena
Licensed Year(s): 2019 2018
Summary: 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...

Licensed Year(s): 2019 2018
Summary: 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...

Principal Investigator: Nguyen, Thai-Nguyen
Licensed Year(s): 2006 2005
Summary: The climate and numerous field reports indicate that permafrost should be continuous in the Mackenzie Delta. However, the most recent permafrost map in the Atlas of Canada classifies the delta as having discontinuous permafrost. Yet, no extensive fieldwork covering the entire delta has ever been realized. Unfrozen conditions beneath the ground, near shifting channels, have been recognized by vario...
