The goal of the OA-ICC is to act as a hub to communicate, promote and facilitate international activities on ocean acidification. These are divided into three categories: science, capacity building, and communication. The target audience is not only scientists but any group or individual interested in ocean acidification, such as policy-makers, the media, schools and the general public. The OA-ICC brings together experts to discuss issues of relevance to the global ocean acidification community, organizes training courses, compiles and centralizes information, as well as provides a number of online resources.
