Swath sonar bathymetry during Maria S. Merian cruise MSM15/2 with links to multibeam raw data files

Multibeam data were collected during R/V Maria S. Merian cruise MSM15/2 leading to Black Sea. Multibeam sonar system was Kongsberg Simrad EM-120. Data are unprocessed and may contain outliers and blunders and should not be used for grid calculations and charting projects without further editing. The raw multibeam sonar data in Simrad multibeam processing format (*.all) were recorded with Simrad SIS software running on Windows operating system. 228 files are compressed with GZIP to size of 1.15 GB (2.18 GB without compression). One dataset contains a measurement period of half an hour. Simrad data files can be processed using the software packages CARIS HIPS/SIPS or with the open source software package MB-System.
