The datum was set to WGS84 and the UTM, zone 35 was chosen for navigation and 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 and Smith (1995)]. The multibeam data were pre processed on board by the GMT software and ISMAR's routines and scripts, using the PDS-2000 production DTMS, after conversion to the ASCII format.
Bathymetric data were complemented by the GEBCO data. On-land SRTM topography data was used for mapping, structural analysis, after conversion to NETCDF GMT grid files.
The computing center employed three INTEL based PC running the SUSE GNU-Linux and the Microsoft Windows 2000 O.S., and one SUN workstations running Solaris 8, in addition to portable computer for data acquisition and personal processing. The Linux machines were used as data repositories using the SAMBA software, providing alse network services like WWW server, to share ongoing information and results, and DHCP and NAT.
Photographs and video were taken by digital cameras and video-camera.
