Seabed 2030 — Global mapping
GEBCO / Nippon Foundation
Global collaboration of ~200 organizations. Multibeam sonar, AUVs, satellites.
Goal: map 100% of the ocean floor by 2030. As of April 2026, 28.7% had been mapped to modern standards.
- Bathymetry
- Multibeam sonar
- AUV
- Open data
Roadmap: 50% of the seafloor mapped
2028
Triton — Deep-sea submersibles
Triton Submarines
Vehicles for research and scientific tourism. Mariana Trench record.
Private submersibles capable of reaching the deepest trenches (11 km). Full ocean depth certified vehicles.
- Submersibles
- Full ocean depth
- High-pressure materials
- Research
Roadmap: Multi-passenger abyssal submersible
2027
Development
The Metals Company — Polymetallic mining
The Metals Company
Controversial but strategic. ISA regulatory framework in progress.
Collecting polymetallic nodules from the ocean floor (Clarion-Clipperton Zone). Critical source of nickel, cobalt, manganese.
- Polymetallic nodules
- Autonomous collectors
- Environmental impact
- Critical metals
Roadmap: ISA commercial exploitation permit
