| Apart from the pure TV-system it is necessary to provide seperately the Multicorer which can be borrowed e.g. at the AWI department of Geology (Dr. Jens Matthiessen). The TV-system consits of underwater camera, LED lights, underwater telemetry and board unit. These components are stored on board. Camera, lights and underwater telemetry must be mounted to the Multicorer individually.||||
