Description :
The AA. examine how vegetation, soils, and thaw depth vary across the arctic bioclimate gradient in northern Alaska. One objective is to determine if the patterns of vegetation and active layers observed in the Kuparuk River basin could reasonably 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 of future ecosystem changes in the Low Arctic.
