B31F:
Soil Carbon Stocks, Fluxes, and Vulnerability at Large Spatial Scales I


Session ID#: 8182

Session Description:
Soil carbon is the largest terrestrial carbon stock, but there is little consensus on likely soil-atmosphere feedbacks with climate change, highlighting significant gaps in our understanding of large-scale soil carbon cycling. Static estimates and maps of soil organic carbon pools have existed for decades, but how do dynamic components of soil carbon—such as fluxes across ecosystem boundaries or vulnerability to climate change or management practices—vary at landscape to global scales? What are useful ways to consider fluxes and vulnerability at watershed to regional to global scales, and what are the necessary ingredients for these considerations? Ultimately, what can we reasonably project about future interactions between belowground carbon and the changing climate? We intend this session as a venue for researchers investigating soil carbon stocks, fluxes, and vulnerability at large spatial scales. Approaches that harness data generated by multiple, complementary approaches in order to address large-scale questions are particularly solicited.
