The One Ocean Science Congress is taking place in Nice, France from the 4th to the 6th of June 2025!

The Ocean urgently needs decisive, swift, and unified efforts to address its critical condition and maximize the solutions it offers. This presents a major challenge for the global community at the Third United Nations Conference on the Oceans (UNOC3), to be held in Nice from 9 to 13 June 2025. The goal is to spur action and implement SDG 14, which is the least funded of all Sustainable Development Goals.

CNRS and IFREMER have been tasked with organizing the One Ocean Science Congress (OOSC), a UNOC3 Special Event dedicated to Science, and to provide Heads of State, Government, and the broader society, with comprehensive scientific insights on the Ocean's health and future trajectory. Science-informed decisions should enable the conservation and sustainable use of the Ocean, optimize the solutions it offers, and safeguard the services and benefits it provides to humanity.

The Congress will feature a mix of plenary sessions, including opening and keynote speeches, alongside parallel oral and poster presentations. To enhance interactions between science and society, action and policy, and to engage civil society more broadly, 'townhalls' such as panels and roundtables will also be arranged.

Contributions are welcome on the 10 following themes that are designed to be action- and solution-oriented and to move beyond limited disciplinary confines.

• 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 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

Abstract submission will open from 15 September 2024.
