Description: Permafrost soils are a significant global store of carbon (C) with the potential to become a large C source to the atmosphere. Climate change is causing permafrost to thaw, which can affect primary production and decomposition, therefore affecting ecosystem C balance. We modeled decadal and millennial soil C inputs, decomposition constants, and C accumulation rates by plotting cumulative C inventories against C ages based on radiocarbon dating of surface and deep soils, respectively, in subarctic tundra soils undergoing minimal, moderate, and extensive permafrost thaw near Eight Mile Lake in Healy, Alaska.
Keywords: permafrost thaw, carbon accumulation, net ecosystem production, radiocarbon, soil carbon inventory, carbon pools, tundra
