be extended across the Arctic Slope and expanded to the warmer tundra on the Seward Peninsula as a step towards developing a circumpolar map of active layer thickness. The trends reported hereare useful for palaeo-ecological reconstructions and predictions
-tundra boundary. In particular, the AA. address 2 questions : what is the relationship between active-layer thickness, soil drainage, and vegetation? what are the temporal dynamics of tree colonization and mortality in this thaw-pond complex?
