Session Proposal: Multi-disciplinary perspectives on ocean island and seamount processes from above the top to below the bottom (AGU25)

V020
Multi-disciplinary perspectives on ocean island and seamount processes from above the top to below the bottom

Session ID#: 252035

Session Description:
Ocean islands provide a window into mantle chemistry and dynamics that lead to innovations in our understanding of the properties of Earth’s mantle and its evolution over geologic time. Furthermore, the growth and eventual subsidence of marine volcanic islands alters ocean circulation, biological evolution of island species, and the chemistry of the ocean-atmosphere system. This session aims to unite advancements from a wide range of studies to address questions related to melting and fluid dynamics of the mantle beneath these features, the composition of the mantle sourcing ocean island volcanism, the magmatic and physical expressions of volcanism at ocean islands, impacts of these systems on the ocean-atmosphere system, and relationships between these themes. We intend for this session to highlight the major themes for advances and challenges in seamount and ocean island science, identifying gaps in knowledge that could be addressed through cross-disciplinary collaboration.
