This Subtopic studies how marine ecosystems facilitate the sequestration of CO2 in the ocean. Employing the knowledge gained in Subtopics 6.1 and 6.2, Subtopic 6.3 investigates how CO2 uptake and turnover by marine ecosystems respond to ongoing and future climate change, and collaborates with Topic 2 on past ocean carbon fluxes and climate. Subtopic 6.3 contributes to the overall Program by assessing fluxes of CO2 and other climate active gases across the atmosphere/ocean boundary, one of the major interfaces of the Earth system.
