The ocean urgently needs decisive, swift, and unified efforts to address its critical condition. This is the challenge facing the global community at the third United Nations Ocean Conference (UNOC3), to be held in Nice from 9 to 13 June 2025. To ensure that the political decisions to be taken are rooted in science, IFREMER and CNRS organize the international scientific congress One Ocean Science bringing together 2,000 experts from all over the world.

Nice will host the One Ocean Science Congress organised by the CNRS and the Ifremer from June 4th to 6th 2025 - just before the 3rd United Nations Ocean Conference. Jean-Pierre Gattuso, an oceanographer and CNRS research professor, and François Houllier, president and director of IFREMER, explain the main issues involved.
