Following last summer's record minimum ice cover in the Arctic, current observations from ESA's Envisat satellite suggest that the extent of polar sea-ice may again shrink to a level very close to that of last year. Envisat observations from mid-August depict that a new record of low sea-ice coverage could be reached in a matter of weeks. This animation is a series of mosaics of the Arctic Ocean created from images acquired between early June and mid-August 2008 from the Advanced...

The German Research Vessel Polarstern had to prove its ice breaking capabilities in Arctic waters to gain data on two series of long-term research measurements. After working in regions up to latitude 82° N, Polarstern of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association entered port in Reykjavik (Iceland) on August 10th. "This year, we had to cope with exceptional heavy ice coverage", says chief scientist Prof. Gerhard Kattner. The sea ice covered...

RV Polarstern finished first Antarctic field season within the International Polar YearThe Antarctic deep sea gets colder, which might stimulate the circulation of the oceanic water masses. This is the first result of the Polarstern expedition of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association that has just ended in Punta Arenas/Chile. At the same time satellite images from the Antarctic summer have shown the largest sea-ice extent on record. In the...

Federal research minister aboard the research icebreaker PolarsternIn the Southern Ocean, large quantities of surface-drifting plankton algae are able to significantly reduce the carbon dioxide content of the surface waters, which can affect the global carbon dioxide cycle. This is one of the results from an Antarctic expedition which has just drawn to a close in Cape Town on February 4, and which was led by the Alfred Wegener Institute, part of the Helmholtz Association. On February 5, an...

By Michael McCarthy An astonishing array of wildlife has been unexpectedly found in one of the world's most hostile environments - the pitch-black, freezing extreme depths of the Southern Ocean surrounding Antarctica. More than 700 creatures new to science, ranging from crustaceans and molluscs to carnivorous sponges and free-swimming worms, have been discovered on a series of expeditions exploring the deep waters of the Weddell Sea. No fewer than 585 new species of crustacean were brought...
