Description:
Raw multibeam bathymetry data were collected aboard RV Maria S. Merian during cruise MSM87 using a Kongsberg EM122 multibeam echosounder. The expedition took place during 16.11.19 - 25.11.19, Las Palmas (Spain) - Mindelo (Cape Verde) in the Central Atlantic Ocean. The main aim of MSM87 was to collect new high-resolution seismic reflection data as a pre-site survey for an IODP site on the Cape Verde Plateau as part of the IODP full-proposal 973 'Neogene climate of NW Africa'. Data were recorded inside the Cape Verde and the Mauritanian EEZ as well as outside EEZs. 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 are published according to the FAIR principles.
