Polarsternexpedition ANT-XXIX/6; 8. Juni - 12. August 2013; Kapstadt-Punta Arenas
Ziel der Expedition: Ein interdisziplinäres Forschungsprogramm in Atmosphäre, Meereis, Ozean und Ökosystem im antarktischen Winter, um die physikalischen und biogeochemischen Eigenschaften und Prozesse während der Wachstumsphase des Meereises besser zu verstehen. Fahrt war die erste antarktische Winterexpedition seit dem Jahr 2006. (Kurs wie im Winterexperiment 1992)

AWI sea-ice physicists are working on the sea ice, while the wind is acclerating and the snow drift is increasing.

Polarsternexpedition ANT-XXIX/6; 8. June - 12. August 2013; Cape Town -Punta Arenas (Chile); The aim of the cruise is to carry out an interdisciplinary research programm on atmosphere, sea ice, ocean, and ecosystem during winter to obtain an understanding of physical and biogeochemical properties and processes during the sea ice growth season. It was the first Antarctic winter expedition since the year 2006.

    The Pulse of Heat in the North Atlantic

    The future of the Arctic Ocean will be decided in part in the Fram Strait, a region between Greenland and Svalbard in which warm water flows northward from the Atlantic. The AWI is investigating just how much of that water actually reaches the Arctic

    Microalgae are microscopically small, single-celled algae species and an important source of food in the oceans. AWI researchers examines how changed living conditions as a result of climate change affect Arctic microalgae

  • In uncharted territory: No other research vessel has made it to this point so far - the German polar research vessel Polarstern in front of the floating ice tongue of the 79° North Glacier, Greenland.

    Uncharted territory!

    The ice shield of Greenland is shrinking – at an ever faster rate. To understand why AWI researchers had to take the Polarstern where no other research vessel had ever been – directly to the glacier front. An expedition report

The Marine Soundscape and Anthropogenic Noise

Due to construction work in the sea, shipping, and gas and oil extraction, the oceans are becoming increasingly louder. A comprehensive international study has now shown that this noise affects the behaviour of far more animal species than previously assumed. The researchers call for us to listen closely to the ocean and to finally regulate noise worldwide.

The grand finale to the expedition of a century

After more than a year in the Central Arctic, this Monday, 12 October, the research icebreaker Polarstern returned to her homeport in Bremerhaven. Accompanied by a ‘welcome committee’ of ships that came to greet, the ship entered the North Lock with the morning high tide, at ca. 9:00 am.

Sea-ice extent in the Arctic at a historical low

The Arctic sea-ice extent is the lowest it’s ever been in July since the beginning of satellite observation. The sea-ice retreat is especially pronounced off the Siberian coast, as a result of which the Northeast Passage (also referred to as the Northern Sea Route) was ice-free by mid-July.

  • The wind has opened a lead between ice floes. As the white streaks reveal, the water surface is freezing again immediately. The streaks occur when the wind drifts loose ice crystals.

  • Spitsbergen: When the winter cold leaves behind cracks in the permafrost soil, they tend to attract small rocks and other flotsam transported by springtime melt water streams. When the water in the cracks refreezes and expands, all the deposited material is spit back up, forming these distinctive ring patterns.

    Shipping in the Arctic

  • Arctic and Antarctic - more differences than similarities?

  • Heading for the new MOSAiC ice floe, Polarstern takes the shortest way to the area of interest: via the North Pole. On tghe way north, the sea ice is surprisingly weak, has lots of melt ponds, and Polarstern is able to easily break it.
