Digital Twins of the Ocean - DITTO Decade programme

DITTO supports the development of digital twins of the ocean as a realistic digital representations of assets, processes or systems in the built or natural environment. This will be accomplished by establishing and advancing a digital framework on which all marine data, satellite data and reanalyzes, modelling and simulation along with high-performance computing (HPC) capacities, artificial intelligence (AI) algorithms and specialized tools including relevant best practices will form a new globally shared capacity to access, manipulate, analyze, visualize and effectively use marine information.
DITTO enable users and partners to create their own digital twin of the ocean to answer "what if" questions in support of a wide range of use in the context of ocean development addressing issues such as development of a sustainable Blue Economy and effective Maritime Spatial Planning.

Duration: 01/07/2021 - 30/06/2030


The Vision of the DITTO Programme is a world where Digital Twins of the Ocean are used to support ocean protection, ocean governance and a sustainable Blue Economy.


The Mission of DITTO is to develop and share a common understanding of digital twins of the ocean (DTO); to establish best practice in the development of DTOs; and advance a digital framework for DTOs to empower ocean professionals from all sectors around the world including scientific users, to effectively create their own digital twins.


Digital Twins will enable users to address ‘What if’ questions based on shared data, models and knowledge. DTOs empower ocean professionals, citizen scientists, policymakers, and the general public alike to visualise and explore ocean knowledge, data, models and forecasts. The use of Digital Twins is wide and rapidly developing spanning a wide range of use cases from engineering to policy to science to operational services. DITTO will promote co-design of twins, education and uptake to demonstrate the value in the Digital Twins.

DITTO White Paper

The DITTO Whitepaper defines the concept of digital twins of the ocean, lays out the challenges, opportunities for actions and suggestions for their implementation. Moreover, it introduces the six working groups of DITTO, each focusing on one key element in the development of digital twins of the ocean:

WG 1: Supportive ocean observations and data delivery

WG 2: Data analytics and prediction engines

WG 3: Data lakes and interoperability

WG 4: Interactive layers and visualisations

WG 5: Framework – architecture, design and implementation

WG 6: Education, training and capacity development

"Digital Twins of the Ocean will bring together ocean data, models and digital information with those who are planning and regulating human ocean interactions. They will become an indispensable element of sustainable development of the ocean space"
