The carbon cycle is the primary mechanism by which ocean processes determine future atmospheric CO₂ concentration and associated climate changes. Ocean acidification affects all marine biota and future ocean carbon fluxes and ocean-atmosphere CO₂ exchange. This session includes presentations on the ocean carbon cycle, its interactions with the biogeochemical cycles of nitrogen and other nutrient elements, and ocean acidification. Processes of interest are ocean-atmosphere exchange, fluxes across the pycnocline, interactions of CO₂ with the carbon cycle that determine the future course of ocean acidification and ocean CO₂ concentration, and acidification impacts on biota.
