Multibeam data were collected during RV Polarstern cruise ANT-XIII/3. Data are unprocessed and may contain outliers and blunders. Therefore the data should not directly be used for grid calculations and charting projects but need to be edited furthermore. The dataset consists of files in ATLAS ascii multibeam format including 'record control words' (*.dux). Atlas DUX data files can be processed using the open source software package MB-System (Caress et al., MB-System: Mapping the Seafloor,http://www.mbari.org/products/research-software/mb-system/ 2021). Values of depths and lateral distances are averaged with neighbouring beams.Ancillary sound velocity profiles (SVP) for data calibration are not part of this dataset publication.

These data should not be used for navigational purposes.Data were provided to PANGAEA by Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research personnel (contact: infobathy@awi.de).
