Should governments prioritize funding for projects to map the entire ocean floor?
Prince Albert II of Monaco has inaugurated the new GEBCO Secretariat to serve as a central hub for global seabed mapping efforts. This new body aims to coordinate data-sharing initiatives and accelerate progress toward the GEBCO 2024-2030 strategy goal of doubling global ocean mapping capacity.
Why it matters
The establishment of a dedicated Secretariat provides the necessary administrative infrastructure to centralize efforts from over 220 international contributors. This move is designed to unify data collection strategies, which remain fragmented despite decades of effort, to provide a more accurate global bathymetric model.
The 2026 GEBCO global grid currently accounts for 104 million square kilometers of seafloor, representing 28.7% of the total ocean area. These maps rely on data contributions from 220 different organizations to refine the global bathymetric model.
The players
Prince Albert II
The Sovereign Prince of Monaco who oversees the principality's initiatives in marine conservation and oceanographic research.
GEBCO Secretariat
A newly inaugurated administrative body based in the IHO offices tasked with coordinating global seabed mapping and data-sharing policies.
International Hydrographic Organization
An intergovernmental organization that coordinates the standardization of hydrographic survey data and provides the facility for the Secretariat.
Sam Harper
The appointed Head of the GEBCO Secretariat responsible for directing global mapping partnerships.
The details
The GEBCO Secretariat coordinates seabed mapping by facilitating technical collaboration and data standardization across the international scientific community. The program operates under the auspices of the International Oceanographic Commission (IOC) and the International Hydrographic Organization (IHO), which provide the framework for integrating hydrographic surveys into a unified digital representation. By centralizing these workflows, the Secretariat intends to standardize the protocols used to convert depth soundings into high-resolution terrain models of the underwater topography.
Timeline
1903: Initial GEBCO charts were first published.
April 2026: Release of the current GEBCO global grid.
October 15, 2026: Official inauguration of the new Secretariat in Monaco.
2021-2030: United Nations Decade of Ocean Science timeframe.
2024-2030: Operational period for the current GEBCO strategy.
The Tech Race
The formation of the Secretariat formalizes the administrative support for the United Nations Decade of Ocean Science. It follows a historical trend of increasing international collaboration to replace isolated survey efforts with a singular, unified global bathymetric standard.
This development primarily affects the scientific community, policymakers, and maritime industries that rely on high-resolution seafloor data for navigation and environmental monitoring. The Secretariat is funded by the Government of Monaco for an initial three-year pilot period.
The takeaway
The creation of a centralized Secretariat marks a significant shift from decentralized mapping to a structured institutional approach. Observers should track the GEBCO 2024-2030 strategy milestones to see if the organization meets its stated goal of doubling total ocean mapping capacity by the end of the decade.
