This session aims to facilitate collaboration and knowledge exchange among projects, networks, and partnerships within the field of underground bioscience research. Serving as an entry point for more specialized sessions on specific aspects such as life in extreme environments, astrobiology, planetary exploration, and beyond-Earth human habitation, the session promotes a cross-disciplinary perspective. By fostering communication between initiatives, it ensures that the outcomes of diverse research efforts are widely disseminated within the EGU community, encouraging a holistic approach to advancing bioscience research in underground laboratories. The session will also explore the infrastructure requirements necessary to support future scientific developments in this unique environment.
