RV Polarstern (meaning pole star) is a German research icebreaker of the Alfred Wegener Institute for Polar and Marine Research (AWI) in Bremerhaven, Germany. Polarstern was built by Howaldtswerke-Deutsche Werft in Kiel and Nobiskrug in Rendsburg, was commissioned in 1982, and is mainly used for research in the Arctic and Antarctica. The ship has a length of 118 metres (387 feet) and is a double-hulled icebreaker. She is operational at temperatures as low as −50 °C (−58 °F). Polarstern can break through ice 1.5 m (4 ft 11 in) thick at a speed of 5 knots (9.3 km/h; 5.8 mph). Thicker ice of up to 3 m (9.8 ft) can be broken by ramming.
