World Maritime Day: The Campus Mondial de la Mer and Major International Events in Resonance

The Campus is “a concentration of multidisciplinary expertise within the region” (Chantal Compère, Ifremer – SONAR 12).

“This interdisciplinarity is what makes us unique on a European scale” (Vianney Pichereau, UBO – SONAR 12).

SONAR Magazine, the expertise of the Campus community

Published twice a year in French and English, SONAR highlights the actors in marine science and technology from the Campus community. Its editorial calendar follows major milestones in the maritime sector.

SONAR 12 (June 2025): A special issue dedicated to the United Nations Ocean Conference.

• Blue Economy and Finance Forum, with Crédit Agricole and Ifremer as participants

Side events contributors: Actimar, ENSTA, Ifremer, French Biodiversity Agency (OFB), Ocean Ops, and Shom.

In diplomatic and public areas, Olivia Lahens, Head of the Campus Mondial de la Mer, met with many community members, including: 52 Hertz, Cedre, CEREMA, CINAV, CLS, ENSTA, Exail, Hytech Imaging, Ifremer, IFM, MNHN Concarneau, Océanopolis, Pôle Mer Bretagne Atlantique (PMBA), Shom, Station Biologique de Roscoff, UBO, and more.

Campus Mondial de la Mer Assembly

The community will gather on December 3, 2025, in Brest.

On the agenda: the 2025–2030 strategy, co-developed with members of the Campus governance council.

Happy World Maritime Day to all!
