Townhall – Marine Knowledge at the Fingertips of our Communities: Designing Digital Twins of the Ocean

Digital Twins of the Ocean (DTO) presents transformative opportunities for advancing sustainable ocean management.
The townhall, through panel discussions and interaction with diverse stakeholders, including scientists, policymakers, and community representatives, will focus on key themes such as:

• Sustainable Ocean Management: Participants will examine practical applications of DTOs. A case study will illustrate how DTOs can enhance decision-making by providing visual but science-based, what-if scenarios, enabling stakeholders to better manage fisheries, prevent pollution, or address climate impacts.
• Observations, Data Ecosystems and Interoperability: Effective DTOs rely on adequate ocean observations and robust, interconnected data ecosystems. The townhall will discuss the importance of integrating diverse data sources, from satellite observations to citizen science. Addressing the challenge of data interoperability, participants will explore ways to ensure that data from different sources can be harmonized and used across platforms, enabling seamless collaboration between ocean researchers, policymakers, and industries.
• DTO Architecture: Technical discussions will cover the core architecture of DTOs, including the development of scalable, modular frameworks that can be adapted to various regions and environmental conditions. Experts will delve into the computational requirements, highlighting innovations in cloud computing and AI that support the development of realistic and accurate DTOs.
• Governance, Equity, and Capacity Building: The success of DTOs hinges on effective governance and equitable access to resources. The townhall will examine the frameworks needed to ensure transparent, inclusive governance of ocean data and models. Special attention will be given to equity in the distribution of DTO benefits, emphasizing capacity-building initiatives for developing countries and marginalized communities. Ensuring that all stakeholders—especially those most affected by ocean changes—can access and contribute to DTOs will be critical in promoting global ocean sustainability.

Through this townhall, participants will collaborate on strategies to harness the power of digital twin technology, advancing collective efforts toward healthier, more resilient oceans for future generations.

The townhall is proposed jointly by the European Commission, the DITTO Decade programme and the G7 Future of the Seas and Ocean Initiative working group.
