The iMagine project was launched under the Horizon Europe programme with the mission to revolutionise how researchers monitor and understand aquatic ecosystems through advanced artificial intelligence (AI) and open science. Running from September 2022 to August 2025, iMagine has brought together a diverse consortium of partners spanning environmental sciences, data management, AI developments, e-infrastructures and Research Infrastructure. Its overarching objective: to bridge the gap between marine and freshwater research communities and cutting-edge digital technologies, creating a robust, open access platform for AI-powered image analysis that serves both scientific and societal needs.Through the development of new AI models, user-driven services, and a powerful cloud-based platform for AI model development, the project has empowered researchers to automate complex environmental assessments, accelerating insights and enabling real-time monitoring across freshwater and marine domains.
