Quantifying carbon fluxes and budgets of boreal forest-tundra landscapes under the influence of rapidly changing permafrost regimes
chercheur principal: Sonnentag, Oliver
Année(s) de permis: 2022 2021 2019 2018 2017 2016 2015 2014 2013
Résumé: The objectives of this research project are to: 1) determine if 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 discontinuous and continuous permafrost zones; 3) determine if the reported decrease (increase) in net CO2 (CH4) exchange based on plot- (<1m2) and ecosystem-scale...

Résumé: This licence is being issued for the scientific research application no. 947. The objectives of this research are 1) to measure how important greenhouse gases, carbon dioxide and methane, are exchanged between tundra surfaces and the atmosphere; 2) relate them to environmental variables such as soil properties and weather. This is all in hopes of understanding more about how future climate cha...
