Swath sonar bathymetry during SONNE cruise SO196 with links to multibeam raw data files

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.多波束数据（Multibeam data）于“松内号”科考船（R/V Sonne）SO-196航次（2008年3月2日至2008年3月27日）期间采集，采集场景涵盖测线剖面航行、往返航程及定点作业时段。数据采集区域位于冲绳海槽（Okiwana Trough），尤其集中在与那国海山（Yonaguni Knoll）与鸠间海山（Hatoma Knoll）周边海域。本次作业采用康斯伯格EM120（Kongsberg EM120）多波束声呐系统，该系统配置191个波束，最大孔径角可达150°。本次航次采集的CTD（温盐深，Conductivity-Temperature-Depth）剖面数据被用于实施折射校正。恶劣天气时段采集的数据质量可能有所下降。本数据集包含未经处理的原始数据，因此可能存在深度与位置相关的误差与粗差。
