Permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT
Principal Investigator: Smith, Sharon S
Licensed Year(s): 2023 2022 2021 2020 2019
Summary: This licence has been issued for the scientific research application No.5419. This project continues the on-going monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT. This phase of the project is largely data collection. Objectives are to provide baseline knowledge of permafrost and terrain conditions (specifically ground temperature and active la...


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: This licence has been issued for the scientific research application No.5221. The project 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 anemome...


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: This licence has been issued for the scientific research application No.5219. Through this project the research group will address the following objectives: 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...


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...


Dehcho Collective on Permafrost
Principal Investigator: Sioui, Miguel PS
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4512. The overall objective is to generate a fusion of leading-edge scientific and Indigenous knowledge on permafrost, and use it as a basis to co-develop new predictive decision support tools and innovative risk management strategies to inventory and manage permafrost and adapt to permafrost thaw. This program will co-d...


Long-term aquatic ecosystem change at the southern limit of permafrost
Principal Investigator: Korosi, Jennifer B
Licensed Year(s): 2019 2018
Summary: The goal is to reconstruct long-term environmental change (hundreds to thousands of years) by examining chemical and biological fossil remains preserved in lake sediment cores, in order to better understand how thawing permafrost impacts lake ecosystems. 1) Water chemistry and plankton survey The research team will collect lake water samples from the study lakes to analyze for water chemistry...


Short and long term effects of forest fires on the stability of carbon pools in the arctic permafrost and subarctic forests (ARCTICFIRE)
Principal Investigator: Koster, Kajar
Licensed Year(s): 2018 2015
Summary: The aim of this project is to study the short term and long term effects of different fire intensities on the decomposition of soil organic matter (SOM) in northern boreal forests under changing fire regimes. The objectives are to: 1) explore the short and long term effects of forest fires with different intensity on above- and belowground biomasses; 2) explore changes in albedo, snow depths an...


Permafrost mapping and food security vulnerability assessment in Jean Marie River First Nation Lands
Principal Investigator: Laurent, Cyrielle C
Licensed Year(s): 2018
Summary: The proposed project will build on the proven methodology used during previous permafrost studies in Jean Marie River First Nation (JMRFN). It aims to extend the vulnerability map by including the McGill and Deep Lake area. These lakes are traditionally and culturally very important to JMRFN (for example, the area surrounding these lakes is also used repeatedly by caribou year after year) and the ...


Impacts of 10 years of climate warming on forests and peatlands in the Dehcho
Principal Investigator: Errington, Ruth
Licensed Year(s): 2018
Summary: After 10 years of warming climate conditions, the Canadian Fire Service is leading a field project to re-measure a series of permanent monitoring plots to identify any changes to the forest stand structure, tree growth rates, plant community composition, tree, shrub, herb, and lichen biomass. These changes will be associated with climate trends and environmental factors such as soil type, presence...
