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-XXII/4 leading to the Scotia Sea. Multibeam sonar system was ATLAS HYDROSWEEP DS2 which was continuously operated by three hydrographers. Data are unprocessed and may contain outliers and blunders. Therefore the data should not be used for high quality grid calculations and charting projects without further editing. The 129 raw multibeam sonar files in SURF format are compressed as TAR archive with GZIP to size of 1.89 GB. One dataset contains a measurement period not exceeding eight hours. SURF data files can be processed using the software packages CARIS HIPS/SIPS or with the open source software package MB-System (http://www.ldeo.columbia.edu/res/pi/MB-System/).
