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 ocean is changing. A new platform from the Copernicus Marine Service makes it possible for anyone to track those changes. Combining decades of observations, MyOcean Health provides an overview of current conditions and short-term forecasts on key ocean variables.
- As ocean temperatures rise, sea ice declines and coastal communities face growing environmental pressures, the demand for reliable ocean data has never been greater. Meeting that demand was a central theme of the 9th Copernicus Marine General Assembly, held in Brussels from 8–10 June as part of the first Digital Ocean Week, organised by Mercator […]
- Discover how the European Digital Twin Ocean is transforming our understanding of the ocean, combining satellite data, ocean models and artificial intelligence to simulate future scenarios and support better decisions for a sustainable ocean future.
- Copernicus Marine Service is welcoming a new Monitoring and Forecasting Centre (COLAB MFC) as a contributor to its network, marking a major step in expanding the service's global reach through international data-sharing partnerships.
- Ocean forecasting is key to understanding and preparing for change. From marine heatwaves to sea ice loss and harmful algal blooms, forecasts help scientists, governments and industries anticipate future conditions and make informed decisions.
- Understanding the ocean starts with data. From satellites orbiting Earth to autonomous floats drifting through deep waters, a global network of technologies continuously monitors ocean conditions in near real time. This article explores how ocean data is collected from space and from the ocean itself.
Use Cases News
- In the inter tropical zone, the ocean water temperature is strongly dependent on the depth. Heated by the sun, the surface water is warm, at around 25 ° C, while the deep water is rather cold (usually 5 ° C at 1000m deep). Ocean Thermal Energy Conversion (OTEC) is a technology that converts this temperature […]
- The aim of SIMROUTE software is to provide a comprehensive, open and easy tool including pre- and post-processing for ship weather routing simulations. The software is constructed considering the Copernicus Marine Environment Monitoring Service wave predictions systems which are available for free use. The code provides the optimized route and the minimum distance route together […]
- Coastal zones are increasingly exposed to the impacts of climate change and more frequent extreme marine events. In Spain, where a large share of the population, infrastructure, and economic activity is located along the coastline, understanding and managing coastal vulnerability has become a priority for public authorities, environmental agencies, and coastal planners.This case focuses on […]
- The northwest Iberian coast is influenced by a low‑salinity water mass formed by river discharges, known as the Western Iberia Buoyant Plume (WIBP). This plume influences coastal circulation, stratification, and upwelling, creating nutrient‑rich zones that support high biological productivity. Understanding how the WIBP behaves is essential for marine spatial planning and water‑quality management. WHISTLE provides […]
- 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 […]
