Nice, France | 3–6 June 2025
The One Ocean Science Congress (OOSC) kicked off today in Nice, France, bringing together global experts to explore the future of ocean science, governance, and sustainability. DOSI is proud to spotlight a series of deep-sea-related events and presentations led by DOSI members and ambassadors throughout the week.

From biodiversity and climate resilience to ocean governance and mining, DOSI is contributing cutting-edge insights that reflect the urgent need for inclusive, science-based stewardship of the deep ocean.
Several DOSI ambassadors and members are attending and actively engaging with the sessions throughout the week. If you are in Nice for OOSC be sure to introduce yourself to discuss deep-sea science and policy.
