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
- 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.
- The Ocean State Report 11 call for contributions is open. Researchers are invited to propose contributions by 4 February 2026 to support a flagship EU publication that delivers independent, peer-reviewed insights on ocean conditions and change, grounded in Copernicus Marine data and supporting evidence-based decision-making.
- Copernicus Marine Service is releasing new global coastal satellite-derived bathymetry products delivering 100 m-resolution depth information in coastal waters. These datasets are designed to support coastal management, marine and climate research, and the Blue Economy.
- The Copernicus Marine Service has launched the beta of the MyOcean Dashboards — interactive, customisable workspaces that put the ocean at your fingertips. Build your own view with maps, graphs and annotations, and explore marine conditions across time, space, depth and variables.
- Copernicus Sentinel-6B, scheduled for launch in November 2025, represents Europe’s next step in monitoring sea level from space. Building on the legacy of Sentinel-6A, it will extend the long-term record of ocean height observations, ensuring the continuity of high-precision satellite altimetry data feeding into Copernicus Marine’s ocean monitoring and forecasting products.
- On 4 November 2025, the Copernicus Sentinel-1D satellite was successfully launched, extending continuity of EU radar observations from space. Its data will support a range of key marine applications, including sea ice monitoring, climate studies, and safe navigation.
Use Cases News
- Aquaculture production is a key activity in the Alfacs Bay of the Ebro Delta. Therefore, maintaining high water quality is essential in the area. In this context, Harmful Algal Blooms (HABs) represent one of the most significant local hazards. The FLORETHA Project enhances local forecasting capability, delivering a new very high resolution (70 m) coastal model application […]
- The Murcia coast, known as the Costa Cálida ("Warm Coast"), stretches approximately 250 km along Spain's southeastern Mediterranean shoreline. This region contributes to ensuring the EU's food security with its significant aquaculture production (around 16.000 fish tonnes per year).The OCEAMMUR project provides high resolution 3D hydrodynamic conditions and forecasts for these production areas. The modelling […]
- The dataset represents the total phosphorus (TP) concentration in water across the Gulf of Finland and the Archipelago Sea from the coastal zone towards the open sea. TP comprises both river-sourced phosphorus, bound in suspended solids, and dissolved forms of phosphorus. The data are provided for representative dates, cloudiness and satellite overpasses allowing, at a […]
- Industrial microplastic pollution heavily impacts the coastal waters of Tarragona and Vilaseca, creating an urgent need for reliable, short-term predictions of where floating plastic will drift and accumulate. To address this, Digital Earth Solutions (DES) developed an operational service that upgrades the SPOT forecasting system by integrating multi-source oceanographic data including Copernicus Marine variables, Puertos […]
- When winter ice begins to move in the Gulf of Riga, ships, coastal communities, and new wind‑farm sites all need an early warning. This service turns Copernicus Marine information into high‑resolution forecasts and maps that show how drifting, ridged ice interacts with planned and existing offshore wind-farm areas—and where that ice is likely to travel […]
