    AbstractThis dataset was collected within the Pelagie Islands Marine Protected Area Project aimed to assess the conservation status and map the distribution of P. oceanica meadows. Bathymetric data were collected by means of the MBES system Reson SeaBat 7125, a 400 kHz and 512 beams 1°x1° multibeam echosounder. A Trimble DGPS system was used for ship positioning and a motion sensor Ixea Octans3000 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 SVP15 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.
