Session Proposal: New Results in Scientific Ocean Drilling from the South Atlantic Ocean (AGU25)

PP021
New Results in Scientific Ocean Drilling from the South Atlantic Ocean

Session ID#: 252140

Session Description:
The South Atlantic Ocean with its slow to intermediate spreading rate and subtropical gyre fills an important gap for studies of oceanic crust formation, hydrothermal fluid flow, deep-biosphere ecosystems, and paleoceanography, which are best known from fast-spreading crustal areas. The uppermost ocean crust in the South Atlantic Ocean records low-temperature hydrothermal processes and exchanges between seawater and basalts. The sediments deposited on top of this ocean crust record the development of Cenozoic ocean circulation in a critical junction between the Atlantic, Pacific, and Southern Oceans, and the development of the South Atlantic Gyre. This session seeks to bring together interdisciplinary studies stemming from recent scientific ocean drilling projects in the South Atlantic Ocean to understand the interactions between lithosphere, hydrosphere, and biosphere in a complex Earth system. We welcome experimental, theoretical, modeling, and observation-based studies from recent and past expeditions of the International Ocean Discovery Program (IODP) and its predecessors.
