JAGO (German research submersible)

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]

Research submersible JAGO

In 2011 JAGO undertook a search to find and inspect Nautilus, one of the first submarines adapted for research.[2]
