Oceanographers in their group have been studying how CO2 emissions affect the ocean system for more than three decades and continue to monitor ocean acidification in all the world’s oceans from coral reef ecosystems to deep North Pacific waters. The website provides valuable information on the ocean carbon cycle and ocean acidification processes, including model simulations of future projections. It also provides ocean carbon data via an easy-to-use Google web-based data portal. The website is easy to navigate and contains many links to ocean acidification data and information sources.
