Charting the Unknown: The Ambitious Quest of Seabed 2030

In a world where the deep ocean remains less understood than the surfaces of distant planets, the international initiative Seabed 2030 stands out as one of the most ambitious scientific endeavors of our time: to produce, by the end of this decade, a definitive map of the global ocean floor. Led by The Nippon Foundation, a Japanese philanthropic organization supporting global maritime initiatives, in partnership with the General Bathymetric Chart of the Oceans (GEBCO), an international scientific body dedicated to mapping the seafloor, Seabed 2030 operates a flagship program of the UN Decade of Ocean Science for Sustainable Development (2021-2030). Its mission is to assemble bathymetric data from across the world, combining historical records, cutting-edge sonar surveys, and novel partnerships, into a unified, publicly accessible high-resolution seafloor grid.

To manage a project of planetary scale, Seabed 2030 employs a distributed structure. Regional Centers, each responsible for areas such as the Arctic and North Pacific, Southern Ocean, Atlantic and Indian Oceans, and the South and West Pacific, coordinate the acquisition, processing, and evaluation of bathymetric data. These regional compilations are then synthesized at the Global Center, hosted by the British Oceanographic Data Center. This decentralized model has enabled rapid growth in both participation and data volume. Legacy datasets are standardized and refined, while new mapping and campaigns continually enhance global coverage. Contributions now flow from research institutions, private companies, NGOs, and citizen scientists– each addition increasing the resolution of the global map and demonstrating the power of collective action in advancing ocean knowledge. The result is a dynamic, increasingly detailed atlas of the seafloor that evolves year after year.

The implications of a fully mapped seabed are expansive. Underwater ridges direct major currents; deep trenches influence global heat and carbon storage; and submerged mountain ranges host ecosystems that are still largely unknown. A comprehensive seafloor map promises to transform multiple domains of science, policy, and industry:

Advancing climate understanding: Ocean circulation drives global weather and climate, and circulation patterns are shaped by the contours of the seafloor. More accurate bathymetry will strengthen climate models, improving projections of temperature shifts, storm intensity, and long-term sea level change.

Supporting ecosystem protection: Marine habitats, from continental-shelf coral gardens to organisms thriving around hydrothermal vents, are defined by subtle variations in seafloor topography. Identifying these features is essential for effective conservation planning, particularly as nations expand networks of marine protected areas.

Improving maritime infrastructure: Modern society depends on subsea cables, global shipping routes, and offshore energy installations. High-resolution bathymetry reduces risk, informs safer engineering decisions, and supports the development of resilient ocean infrastructure.

Enabling scientific discovery: Each newly mapped region creates opportunities to uncover unfamiliar geological formations, biological communities, and environmental processes. The act of mapping itself becomes a catalyst for discovery, broadening our understanding of Earth’s most enigmatic realm.

As Seabed 2030 progresses toward its 2030 target, the global community stands to benefit from an increasingly detailed view of the deep ocean– a shared resource that will guide scientific research, inform policy, and strengthen environmental and economic resilience well into the future.

Accelerating Ocean Mapping: A global initiative relentless in our pursuit of achieving a complete map of the ocean floor by 2030.
