Navire océanographique et brise-glace Polarstern
Since the ship was first commissioned in 1982, Polarstern has completed a total of more than fifty expeditions to the Arctic and Antarctic. It was specially designed for working in the polar seas and is currently the most sophisticated polar research vessel in the world. Polarstern is possession of the Federal Republic of Germany, represented by the Ministry of Education and Research, operated by the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association, and managed by the shipping company Laeisz. The Polarstern spends almost 310 days a year at sea. Between November and March it usually sails to and around the waters of the Antarctic, while the northern summer months are spent in Arctic waters.
The ship is equipped for biological, geological, geophysical, glaciological, chemical, oceanographic and meteorological research, and contains nine research laboratories. Additional laboratory containers may be stowed on and below deck. Refrigerated rooms and aquaria permit the transport of samples and living marine fauna.
Research equipment and measuring instruments are positioned with the help of cranes and winches, sometimes at extreme depths. Special sounding devices with depth ranges up to 10,000 metres and which can penetrate up to 150 metres into the sea floor are available for scientific investigations. The computer system on board continuously captures and stores meteorological, oceanographic and other data as required.
The ship has a crew of at most 44, and offers work facilities for a further 50 scientists and techniciens.
