JAGO is the only crewed German research submersible. The submersible and the crew K. Hissmann and the pilot J. Schauer are based at the GEOMAR Helmholtz Centre for Ocean Research Kiel since 1 January 2006. The former owner was zoologist Hans Fricke from the Max Planck Institute for Behavioral Physiology in Seewiesen, Bavaria. JAGO can dive up to 400 metres (1,300 ft) and can carry one pilot and one observer. It can sample organisms, rock, gas and liquids, and can be used as a rescue and recovery vehicle for the northern Baltic Sea area. Due to the multidisciplinary connection between the GEOMAR and the Christian-Albrechts-Universität zu Kiel, scientists from the Cluster of Excellence "The Future Ocean" have occasional access to the submersible.[1]
In 2011 JAGO undertook a search to find and inspect Nautilus, one of the first submarines adapted for research.[2]

The research vessel ALKOR in a Norwegian Fjord. With the manned submersible JAGO the Kiel marine researchers want to explore the unique ecosystems on the floor of the Norwegian Sea. At the moment JAGO is still relying on an entire team, every maneuver counts. The submersible is free, one last check and JAGO submerges. We are on guard, because JAGO is in action. Karen Hissman navigates the submersible from the bridge; radio contact is the only connection with JAGO. Jürgen Schauer is gliding close to the corals; the pilot has logged over 5000 hours with JAGO. In the coral reef we are usually surrounded by the fish that live there. We call it the nursery of the ocean perch and the fish are really not afraid. They live there and we glide over, it is all very peaceful down there. When we dive down to the reef we usually begin at the base of the reef ... ... and feel our way up slowly to the top and up on the top is of course the most beautiful part of the reef. Here we see every possible color and this in a water depth of 300 to 400 meters at 5 degrees Celsius. And you ask yourself: “How is it possible?”. Jürgen Schauer gathers single samples with the gripper arm; he handles the precious corals carefully. The dive is over. „JAGO to ALKOR, we have surfaced.” Return from a depth of 250 meters. Getting the 3 ton submersible in and out of the water are critical moments in the mission. The scientists take the corals. They have to hurry to make sure they survive. I think that nothing comes close to manned diving. When you are on the sea floor yourself you have a completely different feeling about your environment, about the things you see there, ... ... in three dimensions you perceive them in a different way entirely. These days we also work with deep diving robots, especially in ocean depths and areas where using a manned submersible would be too difficult. But I think that manned research dives will maintain their importance. What is special about manned dives is that you don’t destroy anything when you explore these coral reefs, you can be very selective when taking samples. You can create a comprehensive picture very carefully, you can look at the whole ... ... and I believe that is a great advantage over other methods of taking samples on the sea floor.
