The IOC is the only UN body specialized in ocean science and services. It provides a focus for other UN organizations and agencies with regard to ocean science, observations and data exchange, and services such as global tsunami warning systems. Established in 1960, the Commission celebrated its 50th anniversary in 2010 and currently has 147 Member States. Since the IOC often has its own accreditation within meetings such as those of the United Nations Framework Convention on Climate Change (UNFCCC), the Convention on Biological Diversity (CBD) and the United Nations Conference on Sustainable Development (Rio+20), this gives UNESCO two seats and two voices at the table.
