Abstract:
Raw multibeam bathymetry data were collected aboard RV MARIA S. MERIAN during cruise MSM17/4 using a Kongsberg EM 120 multibeam echosounder. The expedition took place during 10.03.2011 - 12.04.2011 from Dakar (Senegal) to Las Palmas (Spain). Data were recorded in the EEZs of Mauritania. Main research topic of leg MSM 17/4 was the investigation of the oxygen minimum zone (OMZ) in the coastal upwelling areas off Mauretania and Senegal. 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 the former Leibniz Institute of Marine Sciences at the University of Kiel, provision of the data is supported by the DAM Underway Project and published according to the FAIR principles.
