What is the European Digital Twin Ocean?
The European Digital Twin Ocean is a virtual replica of the ocean. It integrates data from many different sources, including satellites, sensors, computer models and even personal devices like smartphone apps. These different data sources constantly “feed” the Digital Twin to provide continuous and up-to-date information about the ocean: from the behaviour of marine species to weather patterns, chemical processes, economic activities and much more.
The European Digital Twin Ocean uses real-time and historical data to represent the past and present and numerical models to simulate possible future scenarios. It can help us answer questions around what’s happened, what’s happening now, and what might happen next with an unparalleled level of detail and accuracy. It fuels knowledge, decision-making and action for a sustainable ocean.
The European Digital Twin Ocean was announced by President von der Leyen at the One Ocean Summit in Brest in February 2022. Its ambition is to make ocean knowledge readily available to citizens, entrepreneurs, scientists and policy-makers by providing them with an innovative set of user-driven, interactive and data visualisation tools. This knowledge will help design the most effective ways to restore marine and coastal habitats, support a sustainable blue economy and mitigate and adapt to climate change.
Leveraging existing European science and assets, it will provide consistent high-resolution, multi-dimensional analyses and forecasts of the ocean. This includes its physical, chemical, biological, socio-ecological and economical dimensions, with forecasting periods ranging from seasons to multi-decades. The European Digital Twin Ocean will transform data into knowledge for everyone's benefit.
Conceived as a public service and a public good , the European Commission has been investing, through the Mission Restore our Ocean and Waters work programme, about €15 million annually since 2021 to develop the European Digital Twin Ocean, including EDITO, its core public infrastructure. This complements the €19 million Iliad project, funded under the Green Deal Call for research proposals to pilot the concept, as well as a number of research projects developing the background science.

EDITO: the core infrastructure of the European Digital Twin Ocean, building on existing assets
In the last decade, the European Union has developed core data infrastructures and ocean services such as
- Copernicus Marine Service (CMEMS)
- Copernicus Data and Information access services (DIAS)
- European Marine Observation and Data Network (EMODnet)
They offer global and pan-European quality-controlled ocean observation data, forecasts, analysis and projections.
They offer global and pan-European quality-controlled ocean observation data, forecasts, analysis and projections.
To develop the core, public infrastructure platform of the European Digital Twin Ocean (EDITO) the European Commission has built on those existing assets, and will connect them with similar systems focused on inland waters (i.e., IDEATION CSA project) and further integrate the whole knowledge value chain, from observations to end-user applications thanks to the latest digital technologies.
To this aim, the European Commission has entrusted 2 main operators behind the CMEMS and EMODnet programmes, namely Mercator Ocean International and the Flanders Marine Institute, to develop EDITO (https://www.edito.eu). EDITO is an open infrastructure, conceived to facilitate the development of digital twin applications and services. It is co-designed and co-developed with all interested parties, who may also contribute with data, models, and intermediate or final services.
The first prototype of the core infrastructure, EDITO, has been unveiled at the Digital Ocean Forum 2024 and is accessible to all via https://www.edito.eu/.
Building on existing European assets, the public infrastructure platform of the European Digital Twin Ocean upgrades, combines and integrates data and services from EMODnet and the Copernicus Marine Service into a single digital framework. By building on these established European infrastructures, EDITO harmonizes high-resolution ocean observation data, forecasts, and analysis.
Users can explore data using cutting-edge tools to inform decisions, build their own digital twins, apps and services, or use existing tools to predict and assess the impact of climate scenarios and human activities.
Importance to other policies and initiatives
The European Digital Twin of the Ocean is a main element of the Digital Ocean Knowledge System under the EU Mission Restore our Ocean and Waters.
It is also a priority in many different initiatives such as the International Ocean Governance, the UN Decade of Ocean Science for Sustainable Development, the All-Atlantic Ocean Research Alliance and the G7 working group Future of the Seas and Oceans Initiative which the EU contributes to.
EDITO builds on the EU Digital Agenda, will be interoperable with Destination Earth, and will benefit from the upcoming initiative for Ocean Observation.
What can we use the public platform of the European Digital Twin Ocean for?
The European Digital Twin Ocean is being built with the cooperation of many users. Some build and run new digital tools like models and simulations, share data, or collaborate with other technical users. Others explore data, run simulations, and consider actions to take based on this information. Everyone has a role to play and benefits from each other’s contributions and interactions via EDITO.
For example:
Researchers, including marine and data scientists, can use the EDITO platform to build and run digital twins, explore data, share their apps and services and secure uptake and legacy for their projects.
Entrepreneurs such as blue economy actors could use EDITO to plan the most fuel-efficient shipping routes or determine the optimal location for an aquaculture pen, wind farm or tidal turbine.
Policymakers such as local authorities could use EDITO to explore different solutions for protecting coastal areas from rising sea levels and climate change threats.
NGOs and environmental groups who advocate for a clean, sustainable ocean and protected marine areas can use EDITO to better support their agendas - from protecting biodiversity, to managing marine pollution.
EDITO can also fulfil an educational purpose for citizens that may lead to a bluer generation. Educators, artists, influencers, journalists, families, and individuals can use What-if Scenarios to learn and show what, where and why some of the most talked-about ocean and coastal issues are occurring, increasing the ocean literacy levels in society.
How does the EDITO platform work to power the European Digital Twin Ocean?
EDITO is a data lake (a high-speed central storage) of all EMODnet and Copernicus Marine products. Building on existing European assets, the public infrastructure platform of the European Digital Twin Ocean upgrades, combines and integrates data and services from EMODnet and the Copernicus Marine Service into a single digital framework. By building on these established European infrastructures, EDITO harmonizes high-resolution ocean observation data, forecasts, and analysis.
Located beside the data are virtual machines that run e.g., Jupyter notebooks, Python, etc. The concept is that, if you want to process Big Data, then you bring your code to EDITO rather than download the data sets. When you access datalab.dive.edito.eu you are running your code on virtual machines beside the data. You are still free to download data from the existing EMODnet and Copernicus Marine Portals to work on locally. EDITO is a complementary service focused on providing Cloud Computing services and the data products on the respective portals are identical to what is available through EDITO.
