OFOS
Cable-operated deep-sea devices
We have several cable-guided deep-sea devices available for various tasks. With an OFOS (Ocean Floor Observation System), seafloor visualizations are recorded over several kilometers, with a camera providing a live stream to the ship and a high-resolution camera taking detailed pictures of the seafloor. To sample cold water springs, a video-guided ring water sampler is used to visually spot the springs and to collect water samples using the water bottles. A video-guided hydraulic grab is available for rock or sediment samples, with its help, samples weighing up to 2T can be lifted from a depth of 6000m.
