T019:
Hydrothermal processes and deep-sea plumes: from solid earth to ocean circulation





Session ID#: 25132

Session Description:
In the proximity of active mid-ocean ridges, hydrothermally induced fluid flow drives heat and mass exchange between the crust and ocean. This flow, which warms the ocean bottom boundary layer and cools the crust and upper mantle, impacts both ocean circulation, evolution of the lithosphere and ultimately climate. Recent modelling studies and data from interdisciplinary surveys and longer-term observatories enable a systems approach to further the understanding of this exchange process.

We bring together members of the solid earth and ocean research communities to discuss interactions between the crust and the oceans, focusing on the mid-ocean ridge and its flanks, through a holistic interdisciplinary approach. We encourage submissions exploring: heating of the ocean bottom boundary layer; measuring and modelling hydrothermal flow; crustal porosity, permeability, alteration and mineral deposition; and the wider implications to understanding of ocean circulation and lithosphere evolution.
