Launched on 9 June 2026 during the 9th Copernicus Marine General Assembly in Brussels, MyOcean Health provides free and open access to key indicators that help track the state of the ocean. Developed by Mercator Ocean International on behalf of the European Commission, the platform brings together more than 30 years of ocean observations and modelled data in an accessible and user-friendly format.

Users can explore six indicators of ocean health: sea surface temperature, marine heatwaves, sea level, ocean acidification, and Arctic and Antarctic sea ice extent. Alongside historical records dating back to 1993, the platform also provides near real-time information and ten-day forecasts for sea surface temperature and marine heatwave activity.

Designed for scientists, policymakers, educators, journalists and citizens alike, MyOcean Health makes it easier to understand how the ocean is changing and how current conditions compare to long-term trends. Interactive maps, charts and graphics can be explored online and shared more widely through embedded visualisations.

The launch comes at a timely moment, as scientists continue to monitor marine heatwaves and the potential development of a strong El Niño event later this year. By making complex ocean data easier to access and interpret, MyOcean Health supports informed decision-making and helps bring ocean science closer to society.

As climate change and other pressures continue to affect marine ecosystems around the world, initiatives such as MyOcean Health highlight the growing importance of accessible and reliable ocean information for understanding and responding to change.
