The NFDI4Earth Pilot German Marine Seismic Data Access is an initiative by the working group Marine Geophysics (AGMAR) of the Deutsche Geophysikalische Gesellschaft. The two main task areas are to establish an agreed standard for data archival and to develop a rescue strategy for legacy seismic data for the foreseeable future. Pilot Projects are one of the community engagement measures of NFDI4Earth (Measure 1.1 in Task Area 2Participate). In open calls ideas for innovative solutions in Research Data Management are collected from the Earth System Science community and selected projects are funded for 1 year. For more information see: https://www.nfdi4earth.de/2participate/pilots. On October 19th and 21st 2022 the first round of pilot projects (2022-2023) presented their progress after half of their project duration in an online event. NFDI4Earth is a consortium of the National Forschungsdaten Infrastruktur (National Research Data Infrastructure) and funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) – project number: 460036893.
