Raw water column data were collected aboard RV MARIA S. MERIAN during cruise MSM127 MAURIBO using a Kongsberg 12kHz EM 122 multibeam echosounder. The expedition took place during 18.03.2024- 20.04.2024 from Las Palmas to Las Palmas (Gran Canaria) in the Northern Atlantic. Data were recorded in the EEZs of Mauritania and Western Sahara and outside. The main objective of the MSM127 (Bremen Cluster expedition MAURIBO) research expedition was aimed at obtaining long sedimentary records by using the Bremen sea floor drill rig MeBo70. 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, provision of the data is supported by the DAM Underway Project and published according to the FAIR principles.
