Nations Advance Ocean Protection, Vow to Defend Seabed
- The 11-day summit on ocean conservation, held in Nice, France, wrapped up on June 13, 2025, marking a significant gathering of global leaders and stakeholders focused on protecting marine ecosystems.
- This event followed months of negotiation and was driven by urgent calls to address ocean threats, with upcoming talks on deep-sea mining and a global plastics treaty set for July and August.
- At the conference, 19 countries ratified the High Seas Treaty, bringing total ratifications to 50, while more than 90 ministers urged limits on plastic production and 14 nations unveiled new marine protected areas.
- John Kerry emphasized that safeguarding the ocean requires addressing the main underlying issue pushing it toward a critical state, while Antonio Guterres cautioned against treating the deep sea as a lawless frontier.
- The summit generated positive momentum for ocean stewardship and financing, but future implementation and strong action against deep-sea mining remain critical for lasting ocean conservation.

Nations advance ocean protection, vow to defend seabed
A global oceans summit wrapped up Friday with world leaders taking major steps toward marine protection and vowing a showdown when nations meet to negotiate rules for deep-sea mining next
The UN Ocean Conference was concluded on Friday, 13 June, on the French Riviera. With, at the key, a lot of commitments, little concrete progress, apart from a salve of ratifications of the Treaty on the High Seas, which should allow for the entry into force of this agreement in 2026 and the creation of a new COP.
The fight against all forms of pollution, conservation of ocean resources and marine biodiversity, including the deep sea, and face the effects of climate change are some promises.
DEBATE: – Mapping the seabed opens doors, write Andreas Bjelland Eriksen and Marianne Sivertsen Næss.
