Objective(s): To study the physical and chemical changes to the climate from permafrost thaw: to determine if carbon dioxide and methane changes differ in different permafrost zones if they respond to differences in amount of precipitation.
Project Description: This licence has been issued for the scientific research application No.4785. 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 (increase) in net carbon dioxide (methane) exchange based on plot- (<1m2) and ecosystem-scale (~1km2) flux measurements made over mostly tundra sites in the continuous permafrost zone generalizable to boreal forest and peatland ecosystems with sporadic and discontinuous permafrost? Do the net ecosystem carbon dioxude and methane exchanges of boreal forest and peatland ecosystems in different permafrost zones respond differently to higher/lower precipitation inputs than, for example, thawing/growing season lengths?
