RV Polarstern (meaning pole star) is a German research icebreaker of the Alfred Wegener Institute for Polar and Marine Research (AWI) in Bremerhaven. Polarstern was commissioned in 1982 and is mainly used for research in the Arctic and Antarctica. It is planned that she will be replaced by Polarstern II around the year 2020,[2] after it was decided that the European Research Icebreaker Aurora Borealis will not be built in her original form.

Polarstern was built by Howaldtswerke-Deutsche Werft in Kiel and Nobiskrug in Rendsburg. 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. Thicker ice up to 3 m (9.8 ft) thick can be broken by ramming.


On 7 September 1991, Polarstern, assisted by the Swedish arctic icebreaker Oden reached the North Pole as the first conventional powered vessels.[3] Both scientific parties and crew took oceanographic and geological samples and had a common tug of war and a football game on an ice floe. Polarstern again reached the pole exactly 10 years later[4] together with the USCGC Healy. She returned for a third time on 22 August 22 2011 at exactly 9.42 a.m. This time she reported the most frequently recurring ice thickness at 0.9 m compared with 2 m in 2001, which corresponds to the long-term average.[5]

On March 2, 2008, one of the vessel's helicopters crashed on a routine flight to the Antarctic Neumayer II base. The German pilot and a Dutch researcher were killed, three other passengers were injured.[6][7]

On October 17, 2008, Polarstern was the first research ship to ever travel through both the Northeast Passage and the Northwest Passage in one cruise, thus circumnavigating the North Pole.[8]

In popular culture[edit]

Polarstern is also the name of the first track of Eisbrecher's (German for Icebreaker) first album, Eisbrecher. Throughout the track in Russian, French and only then in German, narrations are given specifying the dimensions and specifications of an enormous ship, blowing the measurements of the real icebreaker out of proportion (e.g.: length of 236 metres). This way the artist may probably want to reference the international matter of Arctic, the untouchable dominance of Soviet technology pioneers in nuclear-powered icebreakers, and to give the tribute to Russian Arctic researches: Fabian Gottlieb Thaddeus von Bellingshausen, Ferdinand Friedrich Georg Ludwig von Wrangelll, Georgy Alexeyevich Ushakov, Otto Yulyevich Schmidt and Ivan Dmitrievich Papanin.

The ship plays a central role in German musician Schiller's 2010 album Atemlos. A track is titled after the ship. It is also featured in the DVD of the same title, showing the musician's expedition on the vessel.
