Navigating the Arctic Firescape: Indigenous Perspectives on Climate Variations and Land Use Practices in Northern Canada
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5958. The main objective of this project is to understand the perceptions of Indigenous community members, from the ISR and/or the GSA, of how wildfires have modified, and might modify, the landscape and their relationship with it. The Principle Investigator will conduct a dozen semi-structured interviews with community...


Understanding carbon and water fluxes in the forest-tundra ecotone across scales
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No.5536. The project brings together expertise from historically separated knowledge systems and scientific communities, integrating Indigenous perspectives with atmospheric biogeosciences, ecology, airborne remote sensing, and computer science. The project builds on the collective desire to engage community members in knowled...


Scotty Creek 2.0: how interaction between rapidly thawing permafrost and wildfire affect peatland complex trace gas exchanges
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No.5532. The objective of the research project is to elucidate the change in the atmospheric carbon balance of thawing permafrost regions post-disturbance. The impact of disturbances such as fire, especially in conjunction with permafrost thaw, are still not well understood. By installing a new 15-m eddy covariance tower at Sc...


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 research team will address the following objectives: 1) determine the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system; 2) determine how these two types of feedback differ between the sporadic and discontinuous permafrost zones; 3) determine if s the reported decrease (increase) in net carbon dioxide (methane) exchange...


Quantifying carbon fluxes and budgets of boreal forest-tundra landscapes under the influence of rapidly changing permafrost regimes
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2022 2021 2019 2018 2017 2016 2015 2014 2013
Summary: Through this project the principal investigator 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 discontinuous and continuous permafrost zones? Is the reported decrease (increase) in net Carbon Dioxide (CO2)-Methane (CH4) exchange based on...


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 objectives of this project are: 1) to determine the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system, 2) to determine how these two types of feedback differ between the discontinuous and continuous permafrost zones, 3) to determine if the reported decrease (increase) in net CO2 (CH4) exchange based on plot- (<1m2) and ecosystem-scale (~1km...
