Aufnahme von der ersten Tiefsee-Testfahrt des AWI-Tiefseeroboters TRAMPER. 
Forscher und Ingenieure des Alfred-Wegener-Institutes (AWI) hattben während der aktuellen Forschungsreise des Forschungsschiffes Sonne (So 242-2) erste erfolgreiche Tiefsee-Fahrten mit dem autonom agierenden AWI-Unterwasserroboter Tramper durchgeführt. Die Testfahrten des Kettenfahrzeuges erfolgten in einer Tiefe von 4150 Metern in einem Geabiet des tropischen südöstlichen Pazifiks, circa 850 km vor der Küste Perus. Tramper wird von den AWI-Tiefseeforschern im Rahmen der Helmholtz-Allianz Robotische Exploration unter Extrembedingungen (ROBEX) entwickelt und soll künftig im Projekt FRAM als eigenständig agierende robotische Plattform für Sauerstoffmessungen in der arktischen Tiefsee dienen – dort insbesondere am AWI-Tiefseeobservatorium HAUSGARTEN.

Image from the first endurance test for AWI deep sea robot TRAMPER
 
During an expedition on board the research vessel Sonne (So 242-2), researchers and engineers from the Alfred Wegener Institute (AWI) successfully used the autonomous AWI robot, Tramper, for the first time on a deep-sea mission. The continuous-track vehicle’s first demo missions took place at a depth of about 4150 metres in an area of the subtropical Southeast Pacific around 850 km off the coast of Peru. Tramper was developed by AWI deep-sea researchers as part of the Helmholtz Alliance Robotic Exploration of Extreme Conditions (ROBEX) and will be used in future in the FRAM project as an autonomous robotic platform for oxygen measurements in the Arctic deep-sea  - particularly at the AWI deep-sea observatory HAUSGARTEN there.
