Use limitation
The main limitation come from the heterogeneity of the bathymetric data in terms of distribution and quality, and the possible errors generated during the interpolation procedures. Not for navigation.

Statement
Bathymetric data were processed using CARIS HIPS & SIPS software.
Description
Multibeam data were collected using different multibeam echosounders (RESON 8160-50kHz, RESON 8125-455kHz, RESON 7125-400kHz RESON 8111-100kHz, RESON 8101-240kHz e EM 710-60/500kHz), during 18 cruises performed by CoNISMa-UniRoma1 from 2002 to 2019, on board R/V Urania, Universitatis, Tethis and and little boats.
