Intergovernmental Oceanographic Commission
The Intergovernmental Oceanographic Commission (IOC) is a functional body of UNESCO responsible for promoting international cooperation in marine scientific research, ocean observation, ocean services, capacity development, and the sustainable management of the world's oceans. Established in 1960 by the General Conference of UNESCO, the Commission serves as the principal intergovernmental organization within the United Nations system dedicated to ocean science. Headquartered in Paris, France, the IOC coordinates collaborative scientific programmes among its Member States to improve understanding of the oceans, support sustainable development, reduce marine hazards, and strengthen evidence-based ocean governance.
The Intergovernmental Oceanographic Commission coordinates international programmes relating to ocean observation, marine biodiversity, climate science, ocean circulation, marine ecosystems, coastal management, tsunami warning systems, harmful algal blooms, ocean acidification, and marine pollution. Its principal responsibilities include supporting oceanographic research, developing global ocean observing systems, facilitating the exchange of oceanographic data and information, promoting marine scientific capacity-building, and providing scientific advice for policy development. The Commission also oversees major international initiatives such as the Global Ocean Observing System (GOOS), the International Oceanographic Data and Information Exchange (IODE), and the Tsunami and Other Coastal Hazards Warning System, contributing to disaster risk reduction and climate resilience.
In addition to scientific coordination, the IOC promotes international collaboration on sustainable ocean management, marine spatial planning, blue economy initiatives, and the implementation of the United Nations Decade of Ocean Science for Sustainable Development (2021–2030). The Commission works with governments, research institutions, universities, and international organizations to advance ocean literacy, improve marine data accessibility, strengthen scientific infrastructure, and support evidence-based policymaking. It also co-sponsors the General Bathymetric Chart of the Oceans (GEBCO) programme with the International Hydrographic Organization (IHO), contributing to global seabed mapping and marine geospatial knowledge.
The Intergovernmental Oceanographic Commission works closely with institutions including UNESCO, the United Nations, the International Maritime Organization (IMO), the International Hydrographic Organization (IHO), the World Meteorological Organization (WMO), the United Nations Environment Programme (UNEP), the International Seabed Authority (ISA), and the United Nations Convention on the Law of the Sea (UNCLOS) framework. It also collaborates with national oceanographic institutions, hydrographic offices, and scientific organizations worldwide. Through marine science, ocean observation, capacity development, and international cooperation, the IOC plays a central role in advancing knowledge of the oceans and supporting their sustainable management for the benefit of present and future generations.
