Raw multibeam bathymetry data were collected aboard RV METEOR during cruise M216 using a Kongsberg EM 122 multibeam echosounder. The expedition took place during 2026-01-13 – 2026-02-09 from Limassol (Cyprus) to LAs Palmas (Spain) in the Mediterranean and Atlantic. The objective of this cruise is to repeat the zonal Med-SHIP01 line, 8 years after its last repeat (2018), and 15 years after its first implementation in 2011. This will add crucial knowledge on the different scales and magnitudes of variability and trends in circulation, hydrography, biogeochemistry and biology of the Mediterranean Sea. Data were recorded in the Greek and Italian 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.

These data should not be used for navigational purposes.
