This dataset was collected during a survey within GEOSED Project by means of the MBES system Reson SeaBat8111 in the area named Punta Licosa in the Tyrrhenian Sea, Central Mediterranean. The dataset was acquired on the continental shelf in the depth range 10-150 meters.The Multibeam has 101 beams 1°x1° and an operational frequency of 100 kHz. A LandStar 12 channel DGPS system was used for ship positioning and a motion sensor TSS-DMS02-05 was used to provide corrections for attitude data. A Sound Velocity Sensor was installed near the transducers thus providing realtime sound speed for beam steering. A sound velocity profiler Reson SVP20 was lowered through the water column every 6–8 h to get the velocity profile required for the depth computation. The bathymetric data were processed using the PDS2000 software. Data de-spiking was carried out without the application of automatic filters in order to preserve data accuracy and resolution
