Seabed photographs taken along OFOBS profile HE502_6-1 during HEINCKE cruise HE502

The OFOBS system consisted of a towed underwater camera system equipped with both a high-resolution photo-camera (iSiTEC, CANON EOS 5D Mark III) and a high-definition video-camera (iSiTEC, Sony FCB-H11) as well as an integrated sidescan sonar system. The cameras were mounted on a steel frame (140L x 92W x 135H cm), together with two strobe lights (iSiTEC UW-Blitz 250, TTL driven), 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) to track the position of the OFOBS during deployments, with additional positioning information provided by the integrated INS and DVL systems, which was undergoing testing during this cruise. In this dataset seabed photos from a height of approximately 60 cm from the seafloor, depicting an area of approximately 1.5 m**2, with variations depending on the actual height above ground of the system. Conditions were not optimal, with many particles in the water and considerable ship heave.
