Description: Multibeam snippet raw data were recorded using a Norbit STX WBMS multibeam echosounder mounted to the side of the 6.5 m-long aluminum catamaran KLAASHAHN. Data were recorded using frequencies 200 and 400 kHz. Files are stored in the s7k-format, and sorted by date of acquisition and frequency. The 200 and 400 kHz frequency data were manufacturer-calibrated. Correct absorption values have been applied during the export. Data can be processed, e.g., with the open source software package MB-System (Caress, D.W., and D.N. Chayes, MB-System: Mapping the Seafloor, http://www.mbari.org/products/research-software/mb-system/, 2021). No SVP files exist, due to the low water depths (4-7 m), the values of the inbuild sound velocity sensor can be used throughout the water column. The investigation site was located in the Southern Baltic Sea close to the city of Rostock (Germany) and includes three habitat types: seagrass meadows, a mussel covered reef, and coarse sand and gravel areas. Distance to the shoreline was 500 to 1000 m, and water depth varied between 4.5 and 6.5 m.
