Methane Cold Seep Processes, Dynamics, and Impacts
Session ID#: 248471
Session Description:
Seafloor cold seeps are broadly distributed and widely recognized as an important component of the global carbon cycle, serving as a physical pathway and biological filter for hydrocarbons (particularly methane) migrating from subseafloor reservoirs into the ocean. Hydrocarbons in cold seep systems drive a wide range of interconnected biogeochemical processes in the shallow subsurface, at the seafloor, and in the overlying water column, resulting in complex geochemical gradients, distinct geomorphologies, and biodiverse chemosynthetic communities. The impacts of cold seeps on the surrounding environment are complex, highly dynamic, and sensitive to external perturbation. This multidisciplinary session seeks contributions that advance our understanding of cold seep processes, dynamics, and impacts. We welcome contributions on topics including, but not limited to, geologic control of seepage, subsurface fluid migration, biogeochemical cycling, chemosynthetic ecosystems, carbonate geochemistry, seep detection/distribution, and fossil cold seeps. Results from field, laboratory, theoretical, and numerical simulation studies are welcome.
