Landscape Effects and Changes in Permafrost Depth in Atqasuk, Alaska
Thaw depth was measured in a tundra ecosystem in Atqasuk, Alaska. This project focuses on the Atqasuk dry site which has been studied to understand the impacts of experimental warming on the tundra ecosystem. We were interested in how the spatial distribution of plots influences thaw depth measureme...
