Identifying habitats that influence body condition and fitness of adult female caribou in the southern Northwest Territories [traditional knowledge component
Principal Investigator: Kelly, Allicia
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4572. The objective of this project is to describe different plants and vegetation communities that offer different nutritional value to boreal caribou using both scientific and traditional knowledge language. As well as create a plain-language document that shares information on habitats, vegetation communities, plant sp...


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): 2019
Summary: This licence has been issued for the scientific research application No.4543. The overarching project goal is to characterize changes in waterfowl habitat using remote sensing approaches. The first objective is to create wetland type and surface inundation products (maps) for the Arctic-Boreal Vulnerability Experiment (ABoVE) boreal region. The second objective is to assess the efficacy of remo...


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...


Drivers and constaints of ecological change in the western Arctic
Principal Investigator: Lantz, Trevor C.
Licensed Year(s): 2019 2018 2017
Summary: This license has been issued for the scientific research application No.4431. The objectives of this research are: 1) to use remote sensing (Landsat, QuickBird, InSAR, Airphotos, UAVs, etc.) to document regional landscape change (tundra fire, infrastructure, saline flooding, slumps, subsidence, vegetation change, lake drainage/expansion, etc.); and, 2) to use field sampling and monitoring to d...


Future of Tundra-Atmosphere Climate Interactions
Principal Investigator: Lafleur, Peter M
Licensed Year(s): 2019
Summary: The overall goal of this project is to increase the knowledge of how tundra environments interact with the atmosphere and predict how changing tundra vegetation will affect future climates. Tundra ecosystems exchange energy, water and carbon gases with the atmosphere, which are important elements of the climate system. As tundra vegetation reorganizes in response to global warming, these exchange ...


Vegetation Productivity on the Bathurst Caribou Range
Principal Investigator: Danby, Ryan K
Licensed Year(s): 2019 2018
Summary: The two main objectives are: to map changes in vegetation productivity on an annual basis across the Bathurst caribou herd’s range using satellite imagery obtained from NASA’s MODIS sensor (available since 2000) and analyze these data to identify where the most significant changes have occurred; and to collect and analyze data on the growth, establishment, and mortality of shrubs and trees over th...


Understanding changes in aquatic ecosystem health and water quality in the Fort Good Hope – Ramparts Area
Principal Investigator: Gurney, Kirsty E.
Licensed Year(s): 2019 2018 2017
Summary: The project aims to build community partnerships, identify field sites, and develop and implement sampling protocols for long term, community-based, monitoring of wetland ecosystems near Fort Good Hope (FGH). Whereas some wetlands in the study area have either already been, or are likely to be, impacted by a wide range of industrial activities, including development of oil and gas and associat...


Do diversity gradients and wildfires interact to facilitate tree range expansion across a broad latitudinal scale?
Principal Investigator: Reid, Kirsten
Licensed Year(s): 2019 2018
Summary: The overarching research goal of this project is to determine what conditions facilitate tree range expansion across the western Canadian boreal-tundra ecotone. Using a biogeographical, multi-trophic level approach, the research team aim to determine: 1. how multi-trophic level species composition changes across the tundra and which conditions dictate these changes; and, 2. the constraints, dri...


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): 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): 2019 2017 2016 2015 2014 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 ...
