Recent Advances in Hydrothermal Vent Ecosystem Studies Gained Through The Application of Interdisciplinary Research

Session ID#: 161930

Session Description:
Active hydrothermal vent systems are vital components of the ocean system, influencing elemental budgets, exchanging heat with the Earth’s interior, and hosting unique biological communities. Recent interest in inactive hydrothermal sulfides has revealed them to be unique ecosystems, distinct from their active counterparts, yet relatively less understood.  Additionally, these inactive sulfides are potential targets for deep-sea mining, further necessitating studies concerning their importance as seafloor biomes and their role in ocean geochemical cycling.  This session will present results of studies that use interdisciplinary approaches to generate new insights into the biology, chemistry and geology of hydrothermal ecosystems including high-temperature and diffuse-flow vents as well as  inactive sulfides and local host rock.  We particularly welcome abstracts that address connections between basic science and policy relating to hydrothermal vent ecosystems and proposals to produce mineral resources from marine hydrothermal systems. Contributions from early career researchers are strongly encouraged.
