Raw water column data were collected aboard RV METEOR during cruise M215 using a Kongsberg EM 710 multibeam echosounder. The expedition took place during 2025-12-17 – 2026-01-10 from Heraklion (Greece) to Limassol (Cyprus) in the Mediterranean. The overall scientific aim of the studies on the Santorini-Kolumbo System is to reconstruct geological processes that determine tsunamigenic volcanic extreme events and to improve short-term probability estimates for extreme events through new monitoring approaches. Data were recorded in the Greek EEZ. Sound velocity profiles (SVP) were applied on the data for calibration. Please see environmental data and the cruise report for details. The data are unprocessed and can therefore contain incorrect depth measurements (artifacts) if not further processed. Note that refraction errors may occur when no proper SVP is applied. Data acquisition was done by GEOMAR Helmholtz Centre for Ocean Research Kiel, provision of the data is supported by the DAM Project Underway Research Data and published according to the FAIR principles. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.994139"! ** These data should not be used for navigational purposes.
