Understanding the impacts of thermokarst lakes on permafrost stability, C cycling and greenhouse gas emissions

This research integrates field studies in a range of disciplines (geomorphology, geophysics, paleoecology, hydrology, limnology) with process modeling of permafrost thaw, lake formation, carbon cycling, and greenhouse gas (GHG) emissions to understand how permafrost degradation in the Arctic, particularly thermokarst-lake evolution, affects long-term atmospheric trace gas dynamics by releasing ancient carbon (C) stored in permafrost as carbon dioxide (CO2) and methane (CH4).
