Influence of changing active-layer thickness on permafrost peatland trace gas exchanges and carbon balance
Principal Investigator: Sonnentag, Oliver
Licenced 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 ...


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
Licenced Year(s): 2019 2018 2018 2017 2016 2015
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 sporadic and discontinuous permafrost zones? Is the reported decrease (increase) in net carbon dioxide (methane) exchange based on flux measur...


Quantifying carbon fluxes and budgets of boreal forest-tundra landscapes under the influence of rapidly changing permafrost regimes
Principal Investigator: Sonnentag, Oliver
Licenced Year(s): 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...
