AH21A:
Updates, Advancements, and Projections on the State of the Ocean Carbon Cycle (SOCC): How the Ocean is "SOCC"ing it to us! I

Submit an Abstract to this Session

Session ID#: 11441

Session Description:
The global ocean is a major sink of anthropogenic carbon dioxide (CO2), significantly slowing the accumulation of this important greenhouse gas in the atmosphere. The physical, biological, and chemical processes and exchanges that occur in and across ocean and atmosphere represent a major control on ocean CO2 uptake. This session will feature new observations, process studies, and modeling advancements that further our understanding of the carbon cycle in the ocean and its connection to ecosystems and climate. Spanning regions of the ocean dominated by coastal and equatorial upwelling, deep convection, mesoscale eddies, etc., this globally expansive session will include presentations that highlight the strong connection between the ocean carbon cycle and the climate, focusing on physical dynamics, chemistry changes (e.g., ocean acidification), and biological responses and feedbacks.
