MetaSeis - Metadata concept for OBS and 3D Seismic data for the German Community

Reflection seismic data, 2D, as well as 3D, and refraction data such as active OBS (Ocean Bottom Seismometer) data, are the paramount source of information for the deep subsurface structure as they provide by far the highest resolution of any comparable geophysical technique. Within MetaSeis, we will develop unifying data infrastructure and prepare for future archival of reflection 3D seismic data and active OBS data from recent and future research cruises. We aim to adopt and extend existing standards and interoperable vocabularies in the seismic metadata, including metadata quality and validation checks. With this initiative, Helmholtz Metadata Collaboration will serve Germany’s marine geophysics community as represented by AGMAR of the Fachkollegium Physik der Erde of DFG but also contribute to the efforts of NFDI4Earth/DAM/DataHUB and the involved Helmholtz centres to establish a distributed infrastructure for data curation by harmonised data workflows with connections to international data repositories. MetaSeis is funded 2024-2025 by the Initiative and Networking Fund of the Helmholtz Association (Helmholtz Metadata Collaboration HMC, Project Cohort 2023).
