D. Graham (ORNL) is an expert in microbial biochemistry and methanogenesis; he will lead this team. B. Gu (ORNL) is an expert in SOM and its interactions; he will lead tasks to measure rates and mechanisms of soil carbon transformation and carbon-mineral interactions. S. Painter (ORNL) will assist with the interpretation and modeling of soil water measurements and thaw experiments. M. Torn (LBNL) is an expert in the controls of soil organic matter dynamics and GHG flux measurements and isotopic analysis, and N. Taş (LBNL) is expert in microbial community analysis; they will lead in situ manipulation experiments and surface gas flux analysis. W. Riley and C. Koven (LBNL) will coordinate closely with the team on biogeochemical process modeling. B. Newman and J. Heikoop (LANL) are experts in isotopic geochemistry; they will contribute to the geochemical characterization of soil water and permafrost dissolved organic and inorganic matter. Postdoctoral research associates and technical staff at ORNL, LBNL and LANL will assist with each of these tasks.
