An ROV by GEI of Barga was used on a karstic hole in the Kotor Bay.
The datum was set to WGS84 and the Direct Mercator 38N, UTM, zone 33N and 34N were chosen for navigation, display, and data acquisition. The time zone was set to the UTC for the instrumental data acquisition.
The positioning maps and bathymetric images were produced with GMT [Wessel & Smith(1998)].
The multibeam data were pre processed on board by the CARIS and GMT software and ISMAR's routines and scripts, using the SIS production DTMS or raw .all file.
Photographs and video were taken by digital cameras and video-camera.
