Session Details: Permafrost zone soils contain 1330-1580 Pg of organic carbon (C). Permafrost degradation can decrease ecosystem C storage by enhancing microbial activity and ecosystem respiration, but can also stimulate
plant growth and lateral C flux, potentially increasing C stored in vegetation, soil, and sediment. This session invites papers that examine factors causing losses and gains in ecosystem C storage that relate to the question: What is the magnitude, timing,
and form of C release from permafrost zone ecosystems to the atmosphere in a changing climate? Papers may address any aspect of this topic from molecular to global scales, using measurements or modeling to detect or forecast permafrost thaw and its influence
on the C cycle and climate.
Session conveners: Christina Schaedel, Jessica Ernakovich, and Ted Schuur
