Horizontal position of the ship acquiring multibeam bathymetry was determined using differential GPS. Real-time original horizontal resolution of the MBES data was 0.5 m for depths less than 20 m and 2 m for the deeper areas; the final CARIS combined base surface for the MBES data were produced at a 2-m cell size.
Attitude of the vessel (e.g. pitch, roll, and heave) acquiring multibeam bathymetry was monitored by an Applanix TSS POS/MV 320 Version 3 GPS aided navigation system. The vertical resolution of the original bathymetry data is approximately 0.5% of the water depth.
All collected data were processed and used to produce this dataset.
No additional checks for consistency were performed on this data.
