Description
Summary:The 2011 field season continued the development of centimeter-level mapping techniques for marine geology, biology, and archaeology. The ROV Hercules is equipped with a suite of mapping instruments that enable detailed visual and acoustic seafloor surveys. The mapping sensors include a 1,375 kHz BlueView Technologies multibeam, verged color and black and white 12-bit 1360 x 1024 Prosilica stereo cameras, and a 100 mW 532 nm green laser sheet. The sensors are mounted near the rear of vehicle and arranged to image a common area. The vehicle navigation data comes from an RDI Doppler velocity log (DVL), IXSEA OCTANS fiber-optic gyroscope, and a Paroscientific depth sensor.
