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): 2017 2016 2015
Summary: The objectives of this research project are to: 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 the reported decrease (increase) in net carbon dioxide (methane) exchange based on flux measurements made...


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): 2017 2016 2015 2014 2013
Summary: This project will address the following questions: 1) What is the effect of permafrost thawing-induced biophysical and biogeochemical feedbacks on the climate system? 2) How do these two types of feedback differ between the discontinuous and continuous permafrost zones? 3) Is the observed carbon flux measurements in tundra sites in the continuous permafrost zone generalizable to boreal fores...


Influence of changing active-layer thickness on permafrost peatland trace gas exchanges and carbon balance
Principal Investigator: Sonnentag, Oliver
Licenced Year(s): 2017 2016 2015 2014 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...
