Going to AGU 2019? Submit to our #deepbiosphere #biogeochemistry session B076: Microbial Metabolisms and Biogeochemical Processes in Earth's Subsurface
Earth’s subsurface contains the majority of the planet’s prokaryotic life, and is the largest reservoir of organic carbon. Microbial activity in the subsurface shapes biogeochemical cycles from nanometer to planetary scales, over thousand-year timescales. Recent advances in technological, analytical, -omics, and modeling approaches have led to substantial progress toward linking microorganisms to major biogeochemical cycles, as well as in defining the boundaries and limits of life. We encourage abstracts on field, laboratory and theoretical studies that present new insight into the environmental and geological drivers that shape microbial metabolisms, the diversity and imprint of life in and on the subsurface, and the limits of life. This session encompasses all of Earth’s subsurface environments including the marine, continental, and crustal biosphere, and we wish to promote cross-disciplinary dialogue between (but not limited to) microbiologists, geobiologists, geochemists, and modelers.
Session chairs: James Bradley, Cara Magnabosco, Nagissa Mahmoudi
