Purpose Multibeam data were collected to extend the global database of seafloor topography and to provide high resolution bathymetry for the expedition's scientific program.
Abstract Multibeam data were collected during R/V Polarstern cruise ANT-VIII/4. Data recording was executed in Bransfield Strait and across South Shetland Trough and was supervised by a hydrographer. 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 one file in ATLAS ascii multibeam format including 'record control words' (*.dux) which is compressed with GZIP to size of 5.43 MB. Atlas DUX data files can be processed using the open source software package MB-System (http://www.ldeo.columbia.edu/res/pi/MB-System/). Values of depths and lateral distances are averaged with neighbouring beams.
