Oceanic uptake of anthropogenic CO₂ is altering the seawater chemistry of the world’s oceans with consequences for marine biota, ecosystems, and biogeochemistry. Understanding these impacts requires integrative approaches to understand the linkages among ecosystem components and feedbacks to climate. The Ocean Carbon and Biogeochemistry (OCB) program is a scientific community-driven coordinating body that promotes U.S. research and international cooperation to investigate the ocean’s role in the global Earth system. With oversight from the OCB Ocean Acidification Subcommittee, the OCB Project Office has developed this website as a clearinghouse of ocean acidification news and informational resources to support the ocean acidification research community.
