Research Vessel ‘Polarstern’ Departs on Antarctic Expedition

Research Vessel 'Polarstern' Departs for Antarctic Expedition

On Saturday, 8 June 2013 the research vessel Polarstern will be embarking on an expedition to the Antarctic winter. 49 researchers from institutes in twelve countries together with 44 crew members will spend a good two months in the Southern Ocean. They will be exploring the sea ice, the atmosphere and the ocean, until the expedition comes to an end on 12 August in Punta Arenas, Chile.

The research ice-breaker Polarstern is one of the few ships in the world that is able to navigate the Antarctic Ocean in the winter. At this time of the year the Weddell Sea, which is the destination of the expedition, is covered by sea ice, and the members of the expedition team will face temperatures of around minus 30 degrees Celsius and the polar night with only a few hours of twilight. These special conditions have meant that not enough research has been carried out into several physical, chemical and biological processes in the Antarctic winter. The Antarctic plays a key role in the Earth System: It is where the so-called deep water, which drives global ocean currents, is formed.

Chief scientist Prof. Dr. Peter Lemke from the Alfred Wegener Institute has assembled an international team and is taking the most modern research equipment on the expedition in order to obtain baseline data in the wintery Antarctic. On the Greenwich Meridian through to the Antarctic coast the team plans to investigate, for example, the fundamental question of why Antarctic sea ice is expanding slightly whilst the sea ice cover in the Arctic is steadily shrinking.

The second half of the expedition then moves on to the incipient spring: the planned route takes the Polarstern from the Antarctic coast in a north-westerly direction, away from the polar night and into the rising sun. The second central question addressed by the research programme looks at which mechanisms permit the ecosystem of the Southern Ocean to come back to life after the long, cold and dark winter.
