One workstations was used for the acquisition of multibeam data, interfacing by a multiserial and Ethernet link a RESON 8160 P1 processor, an TSS MAHRS MRU and FOG compass, DGPS receiver (Fugro Omnistar), by a MOXA Multi/serial I/O, TC/P and UDP network sockets. The MBES was the 50kHz, 126 0.5°, 150°aperture RESON 8160 (5000 m range). The sonar head is positioned on the ship's keel using a V-shaped steel frame. A Sound Velocity probe at the Sonar Head is interfaced directly to the MBES processor, thus providing the necessary real-time data for the beam-forming. XBT abd CTD casts were used for input of the sound velocity profile to the system.
In addition two data sets were generated and stored on separate computer for backup on HD and CD/DVD. The PDS-2000 was able to build a 20 m DTM during the acquisition of the entire surveyed areas. The existing multibeam datasets will therefore be used for an up-to-date regional bathymetric compilation.
