Multibeam data were measured during R/V Polarstern cruise ANT-XIX/5 along track lines of approximately 4000 NM total length in the Scotia Sea. Data were achieved along the Scotia Arc from Burdwood Bank to King George Island. A multibeam box survey was conducted at the southern part of the Discovery Rise, located at 50°55'S / 35°30'W and covering an area of 90 x 15 NM. A bathymetric survey of 25 x 60 NM was carried out at the eastern part of the South Shetland Trench and its intersection with the Shackleton Fracture Zone, continuing multibeam data from former expeditions. The multibeam sonar system Hydrosweep DS-2 was operated using 59 beams and 90° aperture angle. The refraction correction was achieved utilizing the system's own cross fan calibration. 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.
