During the last Antarctic season, British Polarstern expedition members Dr. Robert D. Larter and Dr. Claus-Dieter Hillenbrand from the British Antarctic Survey (BAS) discovered a new landmark in the Southern Ocean with one of the Polarstern helicopters. This cape is named in honour of the late AWI geologist Christian Hass.
