The Copernicus Marine Service is the marine component of the European Union’s Copernicus Programme. It provides free, open-access, and science-based information on the state of the Ocean at both global and regional scales. This includes data on the physical Ocean (Blue Ocean), sea ice (White Ocean), and Ocean biogeochemistry (Green Ocean).

Funded by the European Commission and implemented by Mercator Ocean International, the service supports the implementation of EU policies and International legal Commitments related to Ocean Governance. It also aims to meet the growing demand for reliable Ocean knowledge across society, and to foster sustainable development in the Ocean sectors by providing state-of-the-art Ocean data and forecasts.

The Copernicus Marine Service contributes to a wide range of applications, including marine protection, climate change monitoring, pollution tracking, maritime safety, sustainable use of marine resources, and the development of renewable Ocean energy. It is also an asset for scientific research and innovation, and plays a key role in raising public awareness of Ocean-related issues by making complex Ocean information accessible to citizens all around the world.
