Raw multibeam bathymetry data were recorded on RV Meteor during M62/3 using an Atlas Hydrosweep DS2 multibeam echosounder. The cruise took place between 03.09.2004 - 27.09.2004 (Recife, Bazil - Mindelo, Cape Verde) in the Southern Atlantic. Data were recorded international waters outside EEZs and within the Cape Verde EEZ with an approximate average depth of around 1500m.M62/3 is aimed to study the impact of hotspot volcanism on the structure and properties of the Earth's surface, crust, and lithosphere.There is no information about sound velocity correction made.There are no extra SVP files provided in this publication.Data are unprocessed and can therefore contain incorrect depth measurements (artifacts) if not further processed. Note that refraction errors can be expected due to the lack of proper SVP.The data are archived at the Federal Maritime and Hydrographic Agency of Germany (Bundesamt für Seeschifffahrt und Hydrographie, BSH) and provided to PANGAEA database for data curation and publication.Data publication is accomplished within work package 2 of the EU Horizon 2020 project iAtlantic- Integrated Assessment of Atlantic Marine Ecosystem in Space and Time (https://www.iatlantic.eu/).

These data should not be used for navigational purposes. Data publishing was realized by Mia Schumacher, GEOMAR.
