WP 3: Climatic control on landscape processes and vulnerable permafrost carbon pools.
Based on IPY permafrost projects TSP and CAPP, we study how landforms, permafrost C pools and their potential remobilization are affected by climate changes. We focus on geomorphological and meteorological control of timing and duration of annual freezing and thawing, and studies of the ground thermal regime. The influence of snow on the ground thermal regime is also included. Permafrost C estimates for the High Arctic and northern Eurasia will be significantly improved. We aim to define SOM lability at the circumpolar scale.
