The OFOBS consisted of a towed underwater camera system equipped with a high-resolution photo-camera (iSiTEC, CANON EOS 5D Mark III). The camera was mounted on a steel frame (140 L x 92 W x 135 H cm), together with two strobe lights, three laser pointers spaced with a distance of 50 cm used to estimate the size of seafloor structures, four LED lights, and a USBL positioning system (Posidonia). An automatic seafloor image was taken every 20 seconds to obtain 'TIMER' stills distributed at regular distances along each of the survey profiles. Additional 'SW_RELEASER' photos were triggered individually when interesting objects appeared in the live feed. During this expedition, no positioning data was available for the OFOBS. Here, image data of 3 OFOBS deployments is presented.
