Seismic Surveys in the Arctic: Visualization on maps and link to data archive at the Alfred Wegener Institute

The contribution presents the MetaSeis Project. Aim of the project is to develop a 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. To ensure long-term archival in the
digital library system "PANGAEA" according to the FAIR-principles, a workflow for the integration of future and
legacy data sets is established. The contribution presents the way in which the Alfred Wegener Institute
makes its seismic data visible and accessible, and the difficulties that arise. Aim is to visualize the marine
seismic profiles measured to date on maps via track lines and to make the corresponding data accessible to
the geoscientific community via data archive "PANGAEA" as part of the "Open Access Agreement".For a first
overview the online portal https://marine-data.de presents the location of the acquired seismic profiles, and
displays meta data as expedition data, contact persons, descriptions of the surveys, and a link to the cruise
report. JPG-Images are provided for some significant seismic profiles. These maps can be quickly updated
after new expeditions to keep the community informed about where data has been collected and where there
are still gaps.In a second step the Marine Data Portal is linked to the data archive “PANGAEA”. The data itself
can be accessed there within the scope of the “Open Access Agreement”. The “PANGAEA” archive provides
the basis for the data to be permanently visible to the scientific community and to be digitally available for
future projects. Another major advantage is that the data is assigned a DOI, which is becoming increasingly
important for the submission of publications, research proposals and other applications.
