Impact of wildfire and forest management on permafrost and post-fire regeneration
Principal Investigator: Baltzer, Jennifer L
Licensed Year(s): 2024 2023 2022 2021 2020 2019
Summary: This licence has been issued for the scientific research application No.5543. This projects two main objectives are to monitor the recovery of NWT forests following wildfire to better understand post-fire changes on forest composition and ground vegetation and to develop baseline information about proposed forest management areas to support assessment of harvesting impacts on these areas. T...


NASA Arctic-Boreal Vulnerability Experiment (ABoVE) Airborne Initiative 2022
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 ...


Hydrothermal Regime of Riparian Terrain in Continuous Permafrost, Western Canadian Arctic
Principal Investigator: Ensom, Timothy P
Licensed Year(s): 2022 2021 2020 2019 2018 2017
Summary: This licence has been issued for the scientific research application No.5168. 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 Inuvik to Tuktoyaktuk Highway (ITH) through ground-based and aerial reconnaissance of stream crossings; 2) Identify relations between physical watershed charact...


Impact of climate change on catchment biogeochemistry in plains and shield regions
Principal Investigator: Olefeldt, David
Licensed Year(s): 2021 2019 2018
Summary: This licence has been issued for the scientific research application No.4734. The objective of this research is to identify impacts of climate change and permafrost thaw on pond methane emissions, and on water chemistry in streams that drain peatland-rich catchments. Impacts on methane emissions will be assessed. Specific objectives are: 1) to characterize the trends and variability in magn...


Using the past to inform the future: A paleoecological perspective of the impacts of drought and fire on lakes, permafrost and forests
Principal Investigator: Pisaric, Michael FJ
Licensed Year(s): 2019 2018 2017 2016
Summary: This licence has been issued for the scientific research application No.4564. The objectives of this research are to examine the frequency and severity of past wildfire and drought (drought-like) conditions in the southern Northwest Territories. Specifically, the research team will examine the following questions: 1) how frequent and severe have fires been in the; 2) are fires becoming more fre...


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'...


Quantifying permafrost thaw
Principal Investigator: Gruber, Stephan
Licensed Year(s): 2019 2018 2017 2016 2015
Summary: The objectives of this research are: 1) to understand better how permafrost differs in temperature and chemical/physical characteristics from place to place; 2) to understand how these different types of permafrost respond to change (climate/disturbance); and, 3) to understand which future changes in permafrost are likely and which are less likely based on computer simulations. High-quality mea...


PermASAR - Airborne SAR campaign on permafrost soils and boreal forests in the Canadian North-West
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...


Application of passive seismic methodologies to the determination of overburden thickness in a permafrost-rich environment
Principal Investigator: McPeak, Sara E
Licensed Year(s): 2018
Summary: The objectives of this project are to test if passive seismics can be used to map the thickness of overburden in a permafrost-rich environment; and, to compare overburden thickness derived from passive seismic data and known overburden thickness from drilling. This project will test to see if the earth’s natural vibration can be used to determine how much sand, gravel, soil and permafrost are a...
