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 measured during R/V Polarstern cruise ANT-XII/4 along transits, survey profiles and partly during stationary work. Data were gained in Southern Ocean and South Pacific Ocean. The main investigation area, situated around the Freeden Seamount, was the Eltanin impact area, which was surveyed during twelve days. In addition, parts of the central De Gerlache Seamounts were surveyed with some track lines. The multibeam sonar system Hydrosweep DS-1 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. |
