Dr. Oliver Sonnentag, Associate Professor at the University of Montreal will be visiting us here in Askja. He has offered to give a talk about his research in Canada:
Given their large areal coverage, high carbon densities, and unique land surface properties and disturbance regimes (e.g., wildfires), the world’s boreal forests are integral components of the global and regional climate systems. A large portion of boreal forests contain permafrost. In northwestern Canada, the northernmost boreal forests grow on cold and thick continuous permafrost. More southerly boreal forests occur in areas with discontinuous and sporadic permafrost. Using satellite remote sensing in combination with micrometeorological measurements, I will discuss how rapidly changing permafrost conditions affect boreal forest cover along the southern limit of permafrost, and how thaw-induced boreal forest cover loss affects land-atmosphere interactions in the southern Taiga Plains ecozone, Northwest Territories.
