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: 2025 2024 2023 2022 2021 2019 2018 2018 2017 2016 2015
Résumé: 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...

From Archaea to the Atmosphere: Integrating Microbial, Isotopic and Landscape-Scale Observations to Quantify Methane Emissions from Global High-Latitude Ecosystems
chercheur principal: Varner, Ruth K
Année(s) de permis: 2019
Résumé: The aim of this project is to combine remote sensing data, field measurements and biogeochemical modeling to improve methane emissions estimates from thawing permafrost peatland landscapes at local, regional and global scales. To accomplish this, the research team will integrate data on water table and vegetation from remote sensing (satellites, unmanned aerial vehicle (UAVs)), with local measurem...

Influence of changing active-layer thickness on permafrost peatland trace gas exchanges and carbon balance
chercheur principal: Sonnentag, Oliver
Année(s) de permis: 2022 2021 2019 2017 2016 2015 2014 2013 2013
Résumé: 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 ...
