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
chercheur principal: Sonnentag, Oliver
Année(s) de permis: 2024 2023 2022 2021 2019 2018 2018 2017 2016 2015
Résumé: This licence has been issued for the scientific research application No. 5890. Through this project my 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...


North Slave Permafrost Study: Characterization and Predicting Discontinuous Permafrost for Climate Change Adaptation
chercheur principal: Wolfe, Stephen A
Année(s) de permis: 2024 2023 2022 2021 2020
Résumé: This licence has been issued for the scientific research application No. 5775. This activity describes and predicts the occurrence of discontinuous permafrost in the northern Great Slave Lake region to assist in planning, development and maintenance of community and industry infrastructure. Changes in climate are affecting permafrost distribution, temperatures and geotechnical conditions. Diffe...


Long-term ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT
chercheur principal: Mamet, Steven D
Année(s) de permis: 2023 2022 2021 2020 2019
Résumé: This licence has been issued for the scientific research application No. 5659. The objectives of this research project are to determine: 1) the status of permafrost landforms; 2) the circumstances surrounding long-term recovery after abandonment of the CANOL No. 1 project, including oil spills and gravel pits; 3) the status of treeline. Sampling and testing will consist of: 1) permafrost: th...


Understanding the impacts of permafrost thaw on water resources and hydrology in the Dehcho region.
chercheur principal: Quinton, William L.
Année(s) de permis: 2022
Résumé: This licence has been issued for the scientific research application No.5120. The long-term objective of this research program is to improve the understanding, parameterisation and prediction of water flow and storage processes in peatland-dominated, thawing, discontinuous permafrost. Over the next 5 years, significant progress toward this long term objective will be made through the following ...


Understanding and predicting the impacts of permafrost thaw on water resources and ecosystems
chercheur principal: Quinton, William L.
Année(s) de permis: 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2001
Résumé: Understanding the integrated eco-hydrological behaviour of ecosystems in the context of thawing permafrost is a major challenge. To meet this, the research team will measure the present surface and near-surface water supplies and their inter-annual variability assuming a condition of no permafrost thaw. The team will also develop new knowledge on the eco-hydrology of the major ecosystems (i.e. bog...


Canada-Korea-USA Beaufort Sea Geoscience Research Program: 2013 Activities
chercheur principal: Dallimore, Scott R
Année(s) de permis: 2017 2014 2013
Résumé: The agencies involved are undertaking this research to acquire geoscience knowledge about the outer shelf of the Beaufort Sea with intent to address knowledge gaps related to thawing of subsea permafrost and gas hydrates. The research will be made publicly available to northern communities, regulators, the scientific community and industry through the release of scientific papers, maps and reports...
