What is the European Digital Twin of the Ocean?
A digital twin is a digital representation of real-world entities or processes. Digital twins use real-time and historical data to represent the past and present, and create models to simulate future scenarios.
The European Digital Twin Ocean's 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 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 on existing European science and assets, the European DTO will provide consistent high-resolution, multi-dimensional descriptions of the ocean. This includes its physical, chemical, biological, socio-ecological and economical dimensions, with forecasting periods ranging from seasons to multi-decades.
It will transform data into knowledge for everyone's benefit.
The European Commission is investing €13 million to develop a core European Digital Twin Ocean. This complements the €19 million project, Iliad, funded under the Green Deal Call for research proposals to pilot the DTO concept.
Building on existing assets
In the last decade, the European Union has developed core data infrastructures and ocean services such as
- Copernicus Marine Service
- 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.
The European Commission will now build on those existing assets, connect them with similar systems focused on inland waters and further integrate the whole knowledge value chain, from observations to end-user applications.
Importance to other policies and initiatives
The 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 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.
The European DTO, build on the EU Digital Agenda, and will benefit from the upcoming initiative for Ocean Observation.
What can we use the Digital Twin Ocean for?
The Digital Twin Ocean is a place of digital co-creation, bringing together different disciplines and communities. Its uses are unlimited.
Researchers will be able to use the DTO to predict how climate change and human activity will affect marine ecosystems, such as the Posidonia meadows and tuna migration. It will help to assess different management plans to choose the most efficient one to implement taking into consideration all parameters, including socio-economic ones.
Entrepreneurs will be able to use the DTO to plan aquaculture farms, taking into account decadal predictions of salinity, currents and extreme heat events, with daily forecasting of oxygen, nutrients, nitrates or harmful algae blooms. This will optimise production and minimise negative impacts.
Local authorities will be able to use the DTO to test the effectiveness of blue and green infrastructures resilient to sea-level rise tested on several scenarios.
Citizens will be able to contribute to biological and ecological observation campaigns (e.g. on plastics) to improve models and use these models for own purposes e.g. extreme weather events alerts, local jellyfish bloom predictions or safe and clean swimming spots.
How will it work?
The European Digital Twin Ocean will consist of a core DTO on which a multitude of tailor-made applications, or 'local twins' can be plugged in. These will answer individual priorities by and for public users and industry, for national, local or thematic policies or sector areas.
The core European DTO will be a public good, connecting the physical, biological and socio-economic dimensions of the ocean.
It will include
- big data, rooted in the ocean data space of the DTO: high volume and variety of data, with long time series, including data on human activities, real time access, all trustable, standardised and ready for latest big data analytics.
- scientific models representing all components of the ocean system, making state-of-the-art science and knowledge outcomes accessible and easy to combine, aiming to unlock the unknowns through transdisciplinary scientific approaches and through predictions of possible future changes of the oceans.
- a single cutting-edge virtual collaborative environment. This digital space will allow everyone to use the digital backbone, the central access to knowledge, diversity of digital and artificial intelligence tools with a capacity to upload and share their own science and data, to revolutionise work practices and help them to make science-based, informed decisions.
