The EU Mission “Restore our Ocean and Waters” (Mission Ocean) aims to protect and restore the health of our oceans and waters by 2030. This mission involves research, innovation, citizen engagement, and blue investments.

The European Digital Twin Ocean (EU DTO) supports Mission Ocean and the European Commission’s key initiative, Destination Earth (DestinE), aiming at creating an accurate digital model of the Earth on a global scale in order to monitor, simulate, and predict interactions between natural phenomena and human activities.

SEADITO, addressing the Horizon Europe call HORIZON-MISS-2023-OCEAN-01-8, focuses on developing analytical methods and tools for the EU DTO. It integrates social-ecological models to establish a comprehensive decision support platform.

SEADITO is going to update and integrate these models for improved Ecosystem-based Management. Case studies in the Baltic Sea, North Sea, Mediterranean, and a Pan-European study will provide the context for multi-actor processes. Components and services are going to be co-designed and tested in targeted user communities.

The results include interoperable, spatially explicit, and DTO-compliant social-ecological decision-support components based on FAIR principles. Additionally, scalable and multi-level social-ecological models, quantitative and qualitative indicators, and workflows are integrated. Testing occurs through the SEADITO Explorer, an interactive spatial platform with visual demonstrators and a Scenario Toolkit (WIST). Learning materials target young researchers, decision-makers, and the public.
