The One Ocean Science Congress (OOSC), organized by CNRS and IFREMER, will be held in Nice, France, 4 to 6 June 2025. It is a UN Special Event serving as the scientific foundation of the Third United Nations Ocean Conference (UNOC3).
This three-day congress will generate science-based outcomes and recommendations to support the global discussions at UNOC3.
We welcome contributions from the international scientific community on 10 key themes, which are aligned with the UN Decade of Ocean Science for Sustainable Development and intended to inform the Ocean Action Panels of UNOC3. These themes are action- and solution-oriented, and designed to transcend traditional disciplinary boundaries:
- Theme 1: Integrating knowledge systems, with a focus on responsibility and respect for the ocean
- Theme 2: Effectiveness, equitability and safety of ocean-based approaches to reach the mitigation and adaptation goals of the Paris Climate Agreement
- Theme 3: Protection and restoration of marine and coastal ecosystems to ensure sustainable and equitable management
- Theme 4: Knowledge of the deep ocean and ways to enable its sustainable use
- Theme 5: Marine genetic resources: from discovery to equitable access and sharing of associated benefits
- Theme 6: Transparency in the fisheries sector, including illegal, unreported and unregulated fishing
- Theme 7: Sustainability, equitability, and safety of ocean-based food systems
- Theme 8: Marine plastic pollution
- Theme 9: Environmental footprint of maritime transport and decarbonization of shipping
- Theme 10: Vibrant science to inform and support ocean action
The congress will include a combination of plenary sessions featuring keynote lectures, as well as oral and poster presentations. To foster greater interaction between science, society, action, and policy, and to involve civil society more broadly, ‘town hall’ meetings will also be organized.
