📢🇧🇷 The 2027 Ocean Decade will take place on 7-9 April 2027 in Rio de Janeiro, Brazil! Co-organised by @IocUnesco @gov_mcti @Prefeitura_Rio, #OceanDecade27 will bring together up to 2,000 participants for three days of dialogue, partnership, and action: ow.ly/PHal50X7MoR

With 40% of Europe’s population living within 50 km of the coast, the ocean is embedded in many of the continent’s cultures, economies, and ways of life. See how National Decade Committees across the region translate global #OceanDecade goals into action: ow.ly/TMvm50ZbRg8

🌍🌊 A major international recognition for our commitment to advancing ocean knowledge and conservation 💪 We are very proud to announce that our initiative to model global zooplankton and micronekton biomass has been officially endorsed as a project of the @UN Decade of Ocean Science for Sustainable Development. These organisms are key components of marine ecosystems, linking primary producers to top predators. They also perform vertical migration, making them crucial players in the transport and sequestration of carbon from the surface layer to the deep ocean, which is of paramount importance in the context of climate change. 🐟 This recognition was granted by the @IocUnesco, with the support of the #OceanDecade Coordination Team, as part of the global effort to build “the science we need for the ocean we want” through strengthened scientific knowledge and international cooperation aimed at addressing the major challenges of understanding, protecting, and sustainably managing the ocean. Our project is now part of the international programme #JETZON (Joint Exploration of the Twilight Zone Ocean Network), dedicated to exploring and understanding the mesopelagic zone, a critical yet still poorly understood ocean ecosystem. This endorsement highlights: 🔵 The strategic importance of low and mid trophic levels in ocean ecosystem functioning, 🔵 The need for open, collaborative, and accessible science, 🔵 And the importance of dialogue between scientists, economic stakeholders, and policy makers. We warmly thank the Intergovernmental Oceanographic Commission (IOC) of UNESCO, the Ocean Decade Coordination Team, as well as all our partners and collaborators for their trust and support. This milestone marks the beginning of a new phase of international momentum for our work, fostering greater collaboration and advancing our collective understanding of the ocean.

🔵 No nation can protect the ocean alone. Since 1960, @IocUnesco has powered global ocean science: 153 nations, 120K daily observations, early warnings across 5 basins. This #WorldOceansDay, let's turn ocean knowledge into action. #OceanDecade youtu.be/PeR-kbTTm2E?si=L8Xh…

🎂 5 years ago, the #OceanDecade endorsed the @OceanDecadeECOP Programme — and it has since become one of the Decade's most meaningful initiatives. In its new Global Report, the programme highlights 5 years of results and achievements. Read it here: ow.ly/QbUO50Z8SYM

The ocean reminds us we are bound together. It shapes our climate, sustains ecosystems & economies, and feeds billions. On World Ocean Day, let's act with ambition & resolve to build a new relationship with the ocean – grounded in science & build on shared responsibility.

🔵 This #WorldOceanDay, the #OceanDecade endorses 73 new Decade Actions to reimagine the future of the ocean through science, partnerships, and action — bringing to 882 the total number of Decade Actions delivering ocean solutions worldwide. 👉 ow.ly/unLT50Z8EVS

This week's #OceanDecade events, with a special #WorldOceanDay focus! 🐧 Antarctica — Domain One: Art performance in Rome, Italy: ow.ly/8MaH50Z80iu 🌊 Ocean Week Brunei 2026: ow.ly/SwPl50Z80iv ⛵ Arved Fuchs's Open Observation Expedition: ow.ly/ZF8X50Z80iw

What is ocean science, and why do we need it? The ocean sustains all life on Earth, and is the planet's largest ecosystem – yet we know very little about it. #OceanScience enables us to understand and protect the ocean and the services it provides to humanity. #WorldOceanDay

Following the Island States Ocean Summit, participants gathered for a collaborative workshop to explore how the Sustainable Ocean Planning and Management Support Platform can help countries access knowledge, partnerships, and financing to turn plans into action. #OceanDecade

🔵 Just published: A new #OceanDecade paper by Laura Meyer, Adam Leadbetter and Peter Burger examine the critical role of private sector ocean data in advancing sustainable ocean governance from national waters to Areas Beyond National Jurisdiction. 👉 ow.ly/9K2W50Z7zq0
