Cold Seeps of the Eastern Pacific – New Technologies Yield New Perspectives on the Biogeochemical Processes of a Well-Studied Subduction Margin

Session ID#: 78396

Session Description:
New technologies for seafloor observation, mapping, and analysis are changing the way scientists explore Earth’s oceans.  This session aims to bring together scientists from recent marine expeditions that have used innovative technologies to analyze cold seeps along the western margins of northern North America and Central America.  These regions have been widely studied to learn about the role of fluids in subduction zones.  However, new technologies for automated mapping and analysis of the seafloor and water-column are leading to fresh perspectives about subsurface fluid-flow processes and the metabolic pathways of biologic communities that depend on those processes, and to new tools that can be more broadly used to explore ocean-covered areas elsewhere in the solar system.  For this session, we invite geologists, biologists, computer scientists, marine engineers, and any others who have contributed to these recent expeditions to describe both the new technologies and the scientific outcomes of the investigations.
