Soil organic carbon storage in a mountain permafrost area of Central Asia (High Altai, Russia)
Abstract The thawing and subsequent decomposition of large stocks of soil organic carbon (SOC) currently stored in the northern circumpolar permafrost region are projected to result in a ‘positive’ feedback on global warming. The magnitude of this feedback can only be assessed with improved knowledg...
