Raw water column data were collected aboard RV METEOR during cruise M192/1 using a 40-100kHz Kongsberg EM 710 multibeam echosounder. The expedition took place during 8.8.23 - 18.8.23 from Piraeus to Piraeus (Greece) in the Mediterranean Sea. The major aims of the first leg of the M192 BRIDGEHELL cruise was to map areas around Milos in the southeast and in the northwest by means of the ship-board shallow-water multibeam system EM 710 and the autonomous underwater vehicle AUV MARUMSEAL 5000 in order to find hydrothermal vents at medium depths. 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 MARUM and the Faculty of Geology and Geo-Environment of University of Athens, provision of the data is supported by the DAM Underway Project and published according to the FAIR principles.

These data should not be used for navigational purposes.These data should not be used for exploitation, e.g. fishing.Data publishing was realised by Mia Schumacher, GEOMAR.
