Purpose Raw multibeam sonar data, format Kongsberg EM-120. One dataset contains a period of normally 30 minutes. Kongsberg raw data can be processed i.e. with the software packages CARIS HIPS/SIPS, Caraibes or with the open source software package MB-System.
Abstract Multibeam data were measured during R/V Sonne cruise SO-196 (2008-03-02 to 2008-03-27) along survey profiles, transits and during stationary work. Data were achieved at the Okiwana Trough, particularly in the area of Yonaguni Knoll and Hatoma Knoll. The multibeam sonar system Kongsberg EM120 was operated using 191 beams and up to 150 deg aperture angle. The refraction correction was achieved using CTD profiles measured during this cruise. The quality of data might be reduced during bad weather periods. The dataset contains raw data that are not processed and thus may contain errors and blunders in depth and position.
