Healthy oceans are fundamental to life on Earth. Protecting these ecosystems and the marine life at their core is a central goal of the European Union's Mission to Restore our Ocean and Waters. This video explores the European Union's efforts to create a digital twin of the ocean (DTO) to support policy and decision-making for marine management and protection. A critical challenge addressed is the integration of complex marine biodiversity data—the "forgotten twin"—to ensure the DTO accurately reflects the reality of ocean life. 🔎 Discover how DTO BioFlow is helping turn marine data into decision-ready knowledge.
