Join the Global Ocean Observing System in Nice, France this June as the global community gathers for the One Ocean Science Congress and the 2025 UN Ocean Conference. Explore our events and advocacy efforts to elevate the ocean observing system as critical infrastructure for society and a sustainable future.
This June 2025, the global community will gather in Nice, France, for two landmark events focused on the future of our ocean. The One Ocean Science Congress (4–6 June), co-organized by CNRS and IFREMER, will bring together leading scientists to generate evidence-based recommendations ahead of the 2025 UN Ocean Conference (9–13 June), co-hosted by the Governments of France and Costa Rica. With the theme of “Accelerating action and mobilizing all actors to conserve and sustainably use the ocean”, the UN Ocean Conference will focus on driving real progress on Sustainable Development Goal 14 (Life Below Water), from advancing international cooperation, to scaling up financing and making ocean knowledge more accessible for better decision-making.
At both events, the Global Ocean Observing System (GOOS) will play an active role, co-organizing and contributing to multiple high-level sessions, panels, and side events. GOOS will advocate for the ocean observing system as critical infrastructure, essential for safeguarding communities, guiding sustainable development, and supporting climate resilience. We will work to elevate the role of ocean data in policymaking, and to unite our global community in calling for support and coordinated investment in sustained ocean observations.
This page highlights ocean observing-related events taking place at the One Ocean Science Congress and the UN Ocean Conference. We invite the ocean observing community to join us and help champion the transformative power of ocean data for a more sustainable future.
Ocean observing events at the One Ocean Science Congress:
4 June 2025
- TM-8: The Need for a Sustained and Fit-for-Purpose Ocean Observing System: From Physics to Socio-Ecosystems
Town Hall | 9:00 – 10:00 | Room 1 | GOOS event!
The Global Ocean Observing System (GOOS) plays a key role in providing critical ocean data that underpins climate modeling, disaster preparedness, and sustainable decision-making. However, major gaps in observational coverage and sustained funding persist, especially in under-observed and vulnerable regions. Advancing a robust, holistic ocean observing system that incorporates economic and societal parameters alongside traditional environmental data is essential to meet the growing societal demand for comprehensive ocean information. This Town Hall will introduce the crucial elements of the transition towards an integrated, comprehensive observing system.

Town Hall | 12:45 – 13:45 | Room 7 | GOOS event!
The aim of this Town Hall meeting is, by briefly recalling a few particularly instructive examples, to discuss possible and original ways of improving the current governance of the Global Ocean Observing System (GOOS) to make it more sustainable. Should GOOS governance move closer to that of the World Meteorological Organization Integrated Global Observing System (WIGOS)? Is this possible without a change in the very paradigms of GOOS? Are other models possible? What balance should be struck between the current approach led by the United Nations’ specialised agencies and more targeted diplomacy led by motivated national entities, as history has sometimes shown?
