New Insights into Oceanic Spreading Centers from Seafloor Observatories Posters


Submit an Abstract to this Session


Session ID#: 48836

Session Description:
Oceanic Spreading Centers (OSC) are complex settings in which geological, hydrothermal, biological and oceanographic processes all interact. The challenges of understanding these systems and of capturing the volcanic and tectonic events responsible for forming the ocean crust has led to the establishment of longterm multidisciplinary seafloor observatories and miscellaneous deep-sea experiments. The resulting datasets require exploration, integration, and modeling at a level that cumulatively must transcend traditional disciplinary boundaries. The goal of this session is to bring together the broad research community working on OSC to better understand 1) magma supply, storage and emplacement 2) the dynamic hydrothermal system that link the geosphere to the ocean and 3) the associated seafloor ecosystems We also  encourage submissions presenting new advances in deep-sea technologies involved in OSC experiments.
