Raw water column data were collected aboard RV METEOR during cruise M204 using a 12kHz Kongsberg EM 122 multibeam echosounder. The expedition took place during 2024-09-27 – 2024-10-20 from Bridgetown (Barbados) to Las Palmas (Spain) in the Central Atlantic. The major aims of M204 Transformers III is to gain new insights into the seismic activity and geological processes at this largely unexplored plate boundary. Data were recorded outside EEZ in international waters. 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, provision of the data is supported by the DAM Underway Project and published according to the FAIR principles. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.973610"! ** These data should not be used for navigational purposes or exploitation.
