Atmospheric Composition and Structure: Biosphere/atmosphere interactionsAtmospheric Composition and Structure: Geochemical cyclesMethane is the most abundant organic chemical in Earth's atmosphere, and its concentration is increasing with time, as a variety of independent measurements have shown. Photochemical...
Biogeochemical aspects of the anaerobic oxidation of methane in diffusive ocean margin sediments Ocean margin sediments are an extensive reservoir of methane, but methane release from these settings to the atmosphere is only a minor component of the global atmospheric methane budget, because of subsurfac...

fluids, and a complex mixture of sediments1,2,3. They are considered as significant geological sources of global atmospheric methane emissions4,5. In the atmosphere, methane is a strong greenhouse gas that is
aspects of climate change are likely to change erosion rates worldwide. Conclusion Lateral distribution of topsoil and associated C and N with soil erosion can affect fluxes, stocks, and persistence of C and N in the soil system. Even though erosion induces a net terrestrial sink for ...
the productivity of the ecosystem. Finally, microbial processes such as methanogenesis, methane oxidation, and denitrification mediate the production and consumption of methane and nitrous oxide that could impact atmospheric levels [10]. Improving predictive models of microbial processes in low-oxygen ...
observations and models from the Atmospheric Carbon and Transport (ACT) - America NASA Earth Venture Suborbital mission. We welcome contributions from the inverse modeling, carbon cycle modeling, satellite remote sensing, methane source quantification, and atmospheric chemical transport modeling communities....

aspects of biogeochemical cycling in the land and ocean—remineralization, denitrification, nitrogen fixation, methanogenesis, etc.—are often crudely parameterized10. Such models have limited prognostic capability. For example, models typically prescribe the ecological niche of a given metabolism with ...
