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): 2022 2020 2019
Summary: This licence has been issued for the scientific research application No.5205. 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...


Pointed Mountain Abandonment Project field surveys
Principal Investigator: Carnochan, Stacey
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4987. The proposed Fieldwork will inform the baseline setting of the environmental site assessment (ESA), while also aiding in the development of feasible mitigation measures that will reduce potential effects that the Project may have on wetlands, wildlife, and vegetation. As well, the fieldwork reconnaissance will provide...


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...


The frontline of permafrost thaw: a transect of eddy covariance towers across the southern Taiga Plains to better understand changing regional carbon and water budgets
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2024 2023 2022 2021 2019 2018 2018 2017 2016 2015
Summary: Through this project the following objectives will be addressed: What is the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system? How do these two types of feedback differ between the sporadic and discontinuous permafrost zones? Is the reported decrease (increase) in net carbon dioxide (methane) exchange based on plot- (<1m2) and ecosystem-scale...


Influence of changing active-layer thickness on permafrost peatland trace gas exchanges and carbon balance
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2022 2021 2019 2017 2016 2015 2014 2013 2013
Summary: The project of the present application is the continuation of year-round eddy covariance measurements of carbon, water and energy fluxes at Scotty Creek, established in 2013. The key methodology is tower-mounted micrometeorological measurements around the eddy covariance technique using an open-path infra-red gas analyzer and a sonic anemometer. These measurements are supported by measurements ...


Deh Cho Region Wetland Mapping Project
Principal Investigator: Merchant, Michael A
Licensed Year(s): 2018
Summary: The main objective of this project is to develop wetland inventory for south western NWT that will be used to provide a baseline for many kinds of planning (including updates to the land use planning processes) and research in support of biodiversity conservation and sustainable management of habitat. Specific objectives are to: 1) develop and use computer-based methods to produce wetland maps wi...


Impacts of wildfire extent and severity on caribou habitat
Principal Investigator: Baltzer, Jennifer L
Licensed Year(s): 2018 2017 2016
Summary: The objective is to improve the empirical foundations for predictive caribou habitat mapping within the forested areas of the Taiga Plains and Taiga Shield Ecoregions in the Northwest Territories, roughly south of Great Bear Lake. The research team will establish a network of long-term study plots across a range of fire characteristics and vegetation types, where the team will measure the rate and...


Impacts of forest fire on discontinuous permafrost in the south-western Northwest Territories
Principal Investigator: Lewkowicz, Antoni G
Licensed Year(s): 2018 2017 2016
Summary: The goal of this project is to look at how permafrost is changing following forest fire over a range of environmental conditions, with the purpose of improving how change is modeled in the future. The fires of 2014 in the southwestern Northwest Territories (NWT) provide an opportunity to examine how discontinuous permafrost responds to disturbances. This work is being carried out in collaboration ...


Active Layer Monitoring Network in the Mackenzie Valley
Principal Investigator: Nixon, Frederick M
Licensed Year(s): 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
Summary: The active layer is the earth overlying permafrost that thaws from the surface and re-freezes each year, and it responds to climate change. Active layer thickness influences vegetation and soil conditions, potentially influencing hunting, forestry, etc. and it’s, thickness, texture and moisture content affects foundations. Changes in the active layer and thaw depth can contribute to slope instabil...


Tammerlane Baseline Studies
Principal Investigator: Hoos, Rick
Licensed Year(s): 2006
Summary: The objective is to obtain sufficient baseline data to develop a lead and zinc mine adjacent to the old Pine Point property. The owl survey to identify species presence and breeding territories in the vicinity of the study area will include an evening broadcast-call program that will commence 0.5 hours after sundown to 0.5 hours before sunrise in April and May. This owl survey will target the Bor...
