Through its role in supporting the Global Ocean Acidification Observing Network (GOA-ON), the IOC helps Member States to coordinate the resources from different countries and organizations needed to understand and tackle the problem of ocean acidification. Every year the ocean absorbs about 25% of human-made carbon dioxide (CO2) emissions, increasing acidity as this CO2 dissolves in the seawater. This change is making it difficult for organisms such as corals and molluscs to produce their shells or skeletons, creating major disruption to marine biodiversity. The Global Ocean Acidification Observing Network was established in 2012 together with a number of organizations including the International Atomic Energy Agency (IAEA) and the U.S. National Oceanic and Atmospheric Administration (NOAA).
"It’s important that we understand what’s happening in the ocean from local to global scales. The IOC is central in helping to bring together different countries, identifying the major issues and facilitating responses." - Dr Bronte Tilbrook, Co-Chair of the Global Ocean Acidification Observing Network
