Water column raw data using the ship's own Kongsberg EM 122 multibeam echosounder was almost continuously recorded during RV METEOR cruise M126. Data were recorded on 25 days between 2016-04-23 and 2016-05-20 in the Atlantic Ocean.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. Ancillary sound velocity profiles (SVP) files from the cruise are archived at the BSH and added to the corresponding multibeam raw dataset doi:10.1594/PANGAEA.957021This publication is conducted within the efforts of the German Marine Research Alliance in the core area 'Data management and Digitalization' (Deutsche Allianz Meeresforschung, DAM).

These data should not be used for navigational purposes.The original bathymetry dataset (doi:10.1594/PANGAEA.866373) was archived in 2016 but not published until April 2023. This dataset has been archived again according to PANGAEA standards. Data publishing was realized by Daniel Damaske & Marianne Rehage, MARUM - Center for Marine Environmental Sciences (University Bremen).
