About
The Copernicus Marine Service, part of the EU’s Copernicus Programme, provides free and reliable information about:
🔵 Blue Ocean
Physical data
Example: Ocean Currents
⚪ White Ocean
Sea ice
Example: Sea Ice change
🟢 Green Ocean
Biogeochemical
Example: Clorophyll activity
Funded by the European Commission and implemented by Mercator Ocean International, it supports EU policies, international commitments, and the Blue Economy.
Its high-quality data contributes to marine protection, pollution control, maritime safety, sustainable ocean use, climate monitoring, and more. The service also helps raise public awareness by offering open access to global and regional ocean data, empowering citizens, researchers, and industries with vital ocean knowledge.

Blue North
Copernicus Marine NCP
Launched in June 2025, Blue North is Iceland’s first project under the Copernicus Marine National Collaboration Programme (Lot 3) implemented by Mercator Ocean International. Lead by the University of Iceland in collaboration with the Natural Science Institute of Iceland and the Icelandic Ocean Cluster.
It aims to boost marine data literacy and user engagement, supporting national implementation of EU policies. Activities include:
User Forum
International Seminar
Training Workshop
Ocean Hackathon
These initiatives build capacity, foster innovation, and promote access to marine data for sustainable fisheries, coastal monitoring, and ocean governance. Blue North Project strengthens Iceland’s position within the Copernicus community and enhances the national material with Icelandic-language resources and real-world marine applications.
Example Use Cases
Sea Ice Monitoring
Monitor drifting sea ice, the age of the ice, its path and more using the Copernicus Marine services.
Tracking Plastic
The marine data can be used to track plastic origin and plastic pathways in the ocean. Explore it here by setting a point where your plastic is starting from and see where it will end up over time. Or change setting to “Origin of Plastic” to see where it comes from.
Biological Monitoring
Understanding the parameters that affect a specific sea species and its migration might allow for forecasting capabilities. Here an example from the Sargassum seaweed.

Copernicus Marine News
- Copernicus Marine has introduced a new global altimetry dataset that significantly improves how scientists observe the ocean.
- The Copernicus Marine Service has launched a new User Feedback & Needs Platform to strengthen user-driven engagement and improve its products and services.
- At the 18th EU Space Conference from 27-28 January, the Copernicus Marine Service will showcase how oceanographic data supports safety, navigation, port infrastructure, and security across Europe’s maritime sector.
- As the High Seas Treaty enters into force, the Copernicus Marine Service provides the scientific backbone for marine protected areas, environmental impact assessments, and evidence-based ocean governance.
- Abstract submissions are open for the session “The Copernicus Marine Service and the European Digital Twin of the Ocean” (OS4.8) at the European Geosciences Union (EGU) General Assembly 2026, which will take place from 3 to 8 May 2026 at the Austria Center Vienna and online. Abstracts are required to be submitted through the EGU […]
- The Copernicus Marine Service recently released a new operational Sargassum detection product as part of its November 2025 service update. This product delivers near real-time monitoring of floating sargassum across the Atlantic and Caribbean basins, strengthening Copernicus Marine’s biogeochemical product portfolio.
Use Cases News
- Coastal regions of small and mountainous oceanic islands such as Madeira are highly vulnerable to what happens on land. Heavy rain, steep slopes and limited wastewater treatment mean that nutrients from agriculture, urban areas and streams can rapidly reach the coastal ocean. These inputs can trigger algal blooms, reduce water quality and disturb fragile coastal […]
- STORMPACT is a coastal monitoring and forecasting service which uses Copernicus Marine data to address the impacts of ocean storms on the shoreline. The service complements national Early Warning Systems at a regional level by a refined decision-aid for storm-induced hazard management up to the beach-scale. STORMPACT is developed by a transnational France-Spain consortium composed […]
- Denmark is transitioning toward a more holistic and data-driven approach to marine environmental monitoring. The Coastal DIAMONDS initiative, led by the Danish Agency for Green Transition and Aquatic Environment (SGAV) introduces a new operational framework designed to support key European directives, including the Water Framework Directive (WFD), the Marine Strategy Framework Directive (MSFD), the Habitat Directive, […]
- There are several coastal, seawater-cooled nuclear power stations in the Northern Baltic Sea. In the event of a nuclear incident where radioactive substances are released into the marine environment, it is crucial for national authorities to monitor the radionuclide transport, retention and accumulation to minimize impacts on human and ecosystem health.The Radiation and Nuclear Safety Authority in Finland (STUK) is responsible for tracking radionuclides in the environment. While STUK routinely models atmospheric dispersion and deposition, tools for oceanic transport have been limited. To address this gap, the Finnish Meteorological Institute (FMI) explored leveraging Copernicus […]
- The Ría de Arousa is a major aquaculture hot spot within the Galician Rías, hosting more than 2,800 mussel rafts out of roughly 3,600 deployed across Galicia. This region accounts for around 11% of global mussel production, highlighting its strategic relevance for European and international aquaculture as well as its exposure to environmental variability.As one […]
