Multibeam data were collected without operator supervision on R/V Polarstern cruise ANT-XV/4 along track lines of about 7000 NM total length. Data were achieved during transits and stationary work in the western Weddell Sea, at the Weddell-Scotia Confluence, and on a transect along the Prime Meridian of about 1300 NM length, between 69°S and 47°S. The multibeam sonar system Hydrosweep DS-2 was operated using 59 beams and 90° aperture angle. The quality of data might be reduced during bad weather periods or adverse sea ice conditions. The dataset contains raw data that are not processed and thus may contain errors and blunders in depth and position.
