Abstract

Restoring and monitoring marine ecosystems are global priorities for international governance. Central to these efforts is the Digital Twin of the Ocean (DTO), a virtual replica powered by real-time data from advanced monitoring platforms. This abstract showcases three ongoing Horizon Europe projects—DIGI4ECO, SUN-BIO, and MERLIN focusing on complementary aspects of this vision. DIGI4ECO provides a global framework, establishing the foundation for the DTO through standardization of ecological metrics and monitoring technologies. SUN-BIO focuses on a fixed monitoring platform integrated with a hybrid green energy generator and restoration hubs, showcasing sustainability at a localized level. MERLIN employs marine autonomous robots for advanced data collection and intervention, enhancing connectivity between monitoring sites. Together, these projects create a comprehensive framework for advancing marine conservation and sustainable resource management through cutting-edge technologies.
