Bathymetry gridded data for the Lido inlet, Venice Lagoon, (2016 survey)
This high-resolution (0.5m resolution) gridded bathymetry data set was collected during April and May 2016 in the Lido inlet (Venice Lagoon) using a Kongsberg Simrad EM 3002 Compact single-head MBES system and a Kongsberg EM 2040 Compact dual-head MBES system. The operational frequency for this survey was set at 360 kHz for the EM 3002 system and at 320 kHz for the Kongsberg EM 2040 system. A Seapath 330 positioning system with a Fugro HP DGNSS corrections was used for ship positioning with the Kongsberg EM 3002 system and a Seapath 300 system supplied by a Fugro HP DGPS was used for ship positioning with the Kongsberg EM 2040 system. Tidal correction of bathymetric data was based on the vertical datum of Punta Salute (1897) (ZMPS - Zero Mareografico Punta Salute) used locally as reference for the tidal measurements. The data was collected aboard small boat MBF1213 of the Hydrographic Office of Italian Navy and aboard small boat Litus, operated by CNR-ISMAR. The bathymetry data was processed with CARIS HIPS&SIPS to account for sound velocity profiles, tide corrections, and manual quality control. The data file is in the ESRI ASCII grid format, WGS-84, UTM zone 33N. Funding for this study came from the Italian Ministry of University and Research RITMARE Flagship Project.
