The datum was set to WGS84 and the UTM (zone33) was chosen for navigation, display, and data acquisition. The time zone was set to the UTC for the instrumental data acquisition. The 1Km resolution bathymetric data of the SRTM30-PREDICTED dataset by [Becker et al.(2008)] were used for preplanning. The lat-lon data were used to produce GMT Netcdf grids, and, after conversion to the UTM Projection, for input to the PDS-2000 ans SIS packages. The positioning maps and bathymetric images were produced with GMT [Wessel and Smith (1995)]. The multibeam data were pre processed on board by the MB-System [Caress and Chayes(2009)] and GMT software and ISMAR's routines and scripts, using the SIS production DTMS or XYZ ASCII converted data. ISMAR's computing center employed several INTEL based PC running the GNU-Linux and the Microsoft O.S., in addition to a SUN-SPARC workstation for multibeam data processing (NEPTUNE). Photographs and video were taken by digital cameras and video-camera.
