Multibeam bathymetry raw data using the ship's own Atlas Hydrographic Hydrosweep DS 2 multibeam echo sounder was almost continuously recorded during RV METEOR cruise M57/2. Data was recorded on 27 days between 2003-02-11 and 2003-03-09. This dataset contains a elongated survey mostly 100 nautical miles of the Namibian coast. The approximate average depth of the entire dataset is around 2600m. Data analysis during data curation revealed that the data are partially of bad to very bad quality (especially in shallow areas), which is indicated in the parameter table. 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. No ancillary sound velocity profiles (SVP) from the cruise are archived at the BSH, thus no SVP added to this dataset. Whether SVP has been changed during the survey is unknown. This publication is conducted within the efforts of the German Marine Research Alliance in the core area "Data management and Digitalization" (Deutsche Allianz Meeresforschung, DAM). Data are unprocessed and therefore may contain incorrect depth measurements (artifacts) without further processing. Data can be processed e.g. with the open source software package MB-System (Caress, D. W., and D. N. Chayes, MB-System: Mapping the Seafloor, http://www.mbari.org/products/research-software/mb-system/, 2021). ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.939054"! ** These data should not be used for navigational purposes. Data publishing was realized by Daniel Damaske, MARUM - Center for Marine Environmental Sciences (University Bremen).
