Interactions between climate, vegetation and the active layer in soils at two Maritime Antarctic sites
In the summer 2000-01, thermal monitoring of the permafrost active layer within various terrestrial sites covered by lichen, moss or grasses was undertaken at Jubany (King George Island) and Signy Island in the Maritime Antarctic. The results demonstrated the buffering effect of vegetation on ground...
