🌊 The ocean sustains life on Earth. It regulates the climate, supports livelihoods and economies, and provides essential resources for billions of people.
This , the theme “REIMAGINE: Beyond the world we know, a new relationship with our ocean” invites us to rethink how we understand, value and care for the ocean.
Through the Intergovernmental Oceanographic Commission (IOC) of UNESCO, more than 153 countries work together to observe the ocean, share scientific knowledge and strengthen the evidence needed for sustainable ocean management. Every day, IOC-coordinated systems deliver thousands of observations and make marine biodiversity data openly accessible to researchers, policymakers and communities worldwide.
As we reimagine our relationship with the ocean, science remains one of our most powerful tools for moving from awareness to stewardship and from commitment to action.
The ocean has no boundaries. Its future depends on our collective action.
