Imagery transects with a camera attached to a frame design for taking pictures in a 50 x 50 cm area. Seabed images transects were carried out by scientific divers during the Heincke HE601 cruise focusing on developing and testing monitoring techniques at the Borkum Reef Ground and Sylt Outer Reef Marine Protected Areas. The camera used was a Canon EOS M6 camera, the pictures were taken perpendicularly to the seabed. The transects were done along a preset track across the reefs, number of pictures per transect varied based on diving time. The seabed images provide insights into the general composition of key species, higher systematic groups and ecological guilds. The images also contain valuable information on how benthic species are associated to each other. Transect files include individual images, whereas metadata of each image including diving depth, date/time, if the image was further analyzed, corresponding diver is found in a separate file. Geographical coordinates of individual images is unavailable.
