Critical environmental challenges affect aquatic ecosystems worldwide, and the need to coordinate research efforts is increasingly urgent. Mesocosms are key Research Infrastructures (RIs) allowing the study of highly complex environments comparable to natural ecosystems. Mesocosm experiments, which offer controlled yet realistic settings, are crucial for understanding and mitigating the impact of various stressors and their combinations on aquatic ecosystems. The AQUACOSM-RI consortium, comprising over 60 individual state-of-the-art mesocosm facilities at 28 host institutions across Europe, has therefore been instrumental in advancing aquatic environmental research across climate zones including marine, brackish and freshwater ecosystems.

The AQUANAVI project (Navigating Grand Challenges and their Mitigation using Aquatic Experimental RIs) aims to create an interactive atlas of aquatic mesocosm-based experimental research. Data, publications, reports and information generated by the AQUACOSM consortium and other mesocosm facilities worldwide will be integrated into a single, accessible platform incorporating Open Knowledge Maps' AI-driven visual discovery tools. The project will foster collaborations and, by enhancing data FAIRness, it will facilitate fast discovery and efficient use of aquatic RIs globally, accelerating the development of environmental mitigation strategies.
