State of the Ocean

Explore the state of our Ocean through key indicators featured in the Ocean Climate Portal, powered by the Copernicus Marine Service. Implemented by Mercator Ocean, the Copernicus Marine Service delivers state-of-the-art data and information across the Blue (physical), Green (biogeochemical), and White (sea ice) Ocean, capturing the effects of global warming and human-driven stressors alongside natural variations.
