The vessel was set-up for data acquisition and navigation with NAVPRO software, interfacing by a MOXA multiserial and Ethernet link several instruments, among them the DGPS by SEAPATH, the Kongsberg EA60 Scientific single-beam echosunder, and the Aanderaa 3660 meteorological station. The position and depth data were also distributed to the CTD data acquisition console (????). A Kongsberg processor running the SIS software, collected the multibeam data, including a SEAPATH MRU, compass, and DGPS. The MBES was the 300kHz, 508 beams 0.5°, 170°aperture EM3002D Dual Head (400 m range) model by Kongsberg. The sonar head is positioned on the ship's keel using a V-shaped steel frame. A Sound Velocity probe at the the Sonar Head is interfaced directly to the MBES processor, thus providing the necessary real-time data for the beam-forming. CTD casts were normally used for input of the sound velocity profile to the system.
