needleleaf classes and permafrost extent after Kotlyakov and Khromova: Land Resources of Russia – Maps of Permafrost and Ground Ice, Version 1, NSIDC 2002) Boreal forests in permafrost regions make up around [...] vegetation – permafrost dynamics can have a potentially high impact on the numerous feedback mechanisms between the two ecosystem components. Increased soil carbon release from thawing permafrost through the [...] to understand how the interactions between the vegetation, permafrost and the atmosphere stabilize the forests and the underlying permafrost. A one-dimensional land surface model (CryoGrid) is adapted

deep permafrost soil carbon pools to rapid thaw and resulting impacts. The three research topics were: (1) Systematic measurement of rapid permafrost thaw, (2) Characterization of deep permafrost SOC stocks [...] PETA-CARB wordle (Graphic: Alfred Wegener Institut) What is Permafrost? Carbon in Permafrost Arctic landscapes, especially those underlain by permafrost, are threatened by climate warming and may degrade in [...] Wegener Institut) Arctic permafrost deposits are estimated to freeze-lock as much carbon in the atmosphere, allowing a potentially significant climate warming feedback loop when permafrost thaws and carbon is
