BN016:
Methane from the Subsurface through the Bio-, Hydro- and Atmosphere: Advances in Natural Hydrate Systems and Methane Seeps in Marine Ecosystems


Session ID#: 28189

Session Description:
Gas hydrates and gas-filled pockets in marine sediments represent enormous repositories of methane. Methane seepage into the ocean fuels chemosynthetic biological communities, supports the formation of new habitats through long-term precipitation of carbonate hard grounds, and potentially has a regional impact on the chemistry and biology of the overlying water column. There has been a rapid advance in the discovery of these sites, with a new appreciation for the ubiquitous nature of hydrate and methane fueled systems at both active and passive continental margins and the recognition that geological or environmental events, such as earthquakes, submarine landslides, and ocean warming, can alter the release of sequestered methane to the ocean. These discoveries change our understanding of the role and scale of methane-based processes to the earth-ocean-atmosphere system. This session seeks to combine multi-disciplinary research topics to assess the current baseline of methane seepage to the global oceans and its environmental impact. We welcome contributions including, but not limited to, geophysical surveys of the subsurface, regional mapping of gas plumes, analyses of source gases and hydrate and their fate in the water column, temporal studies from ocean observatories, sediment and carbonate geochemistry, and biological studies of seep-driven chemosynthetic ecosystems.
