That’s the challenge facing the Nippon Foundation-GEBCO Seabed 2030 Project, a global initiative to deliver a complete map of the ocean floor by 2030. As of the June 2025 update, Seabed 2030 has mapped 27.3% of the ocean floor – adding around four million km² in just one year. Our Seabed 2030 Regional Centers are always available to support ocean mappers in identifying priority areas and encouraging coordinated efforts to map them. We do this by inspiring ocean mapping and compiling available bathymetry into the GEBCO Map. We’re keen to continue encouraging national and regional mapping efforts, and it’s encouraging to see growing contributions from Africa and the Pacific.
