Unravelling Interactions between Large-Scale Ocean Circulation, Biogeochemical Cycles, and Marine Ecosystems

Session ID#: 258179

Session Description:
Large-scale ocean circulation patterns fundamentally control the distribution and transport of biogeochemical resources such as carbon, oxygen, and nutrients. These patterns determine primary production, export fluxes, air-sea gas exchange, oxygen minimum zones, and deep-ocean carbon sequestration across various timescales. However, substantial uncertainties remain about how key circulation features—including the meridional overturning circulation and its regional components, boundary currents, the gyres, tropical circulations, and the Antarctic Circumpolar Current—have evolved historically and how they will respond to future climate forcing. This session invites observational and modeling studies that examine how large-scale circulation influences marine biogeochemical cycles and ecosystems, spanning paleo, present, and projected future climates. We aim to advance understanding of physical-biogeochemical interactions and their feedback mechanisms, with broad implications for marine environment and climate regulation.
