Statement
Bathymetric data were processed using CARIS HIPS & SIPS software.
Description
Multibeam data were collected using different multibeam echosounders (KONGSBERG EM710, SIMRAD EM710, RESON 8160, RESON 8125, RESON 8111 e EM 3002D), during 30 cruises performed by CNR-IGAG from 2003 to 2012, on board R/V Urania, Maria Grazia, Universitatis, Tethis and Minerva Uno.
