Objective(s): To determine the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system.
Project Description: Through this project the following objectives will be addressed: 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? Identical to Scotty Creek, Havkipak Creek and Trail Valley Creek, the core component of my project at Sm... Show more
