The 9th Data Science Symposium took place from April 4 - 5, 2024. This time it was organized by AWI. Established in 2017, this is part of a joint series of symposia of AWI, GEOMAR and Hereon. It aims at building bridges between science methods, science applications, and infrastructure developments. As in previous years, contributions are collected, including ideas or results from ongoing projects. As an infrastructure provider, we are particularly interested in current trends, current and overarching developments and community activities. HGF project-related information (Helmholtz Incubator, pilots and projects within the framework of the Initiative and Networking Fund (IVF)) are as interesting as current developments in High Performance Computing, O2A, as well as other projects related to PoF IV or Data Science and Data Management.
