Scientists from the Alfred Wegener Institute have researched the geology of the seabed in the Labrador Sea on board of the research vessel Maria S. Merian. They have studied the so-called Eirik Drift at the southern tip of Greenland, a structure of several hundred kilometres length formed like a ridge. They discovered a submarine mountain (seamount) at the south-western fringe of their area of investigation that indicates volcanic eruptions during the past few million years.The Eirik Drift...

Researchers in Germany and Canada reported on Thursday that climate change could effect the global food chain by supporting animals with short life spans rather than their larger long-lived predators. Researchers noted that animals showed widely differing "thermal windows" -- a range of temperatures in which they best feed, grow and reproduce, meaning that global warming would have a varying effect on each species. "Climate change will favor species with wide thermal windows, short life...

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...

Climate scientists from the Alfred Wegener Institute present their own prognosis for the first time The ice cover in the Arctic Ocean at the end of summer 2008 will lie, with almost 100 per cent probability, below that of the year 2005 "“ the year with the second lowest sea ice extent ever measured. Chances of an equally low value as in the extreme conditions of the year 2007 lie around eight per cent. Climate scientists from the Alfred Wegener Institute for Polar and Marine Research in...

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...

Drift Expedition NP 35 has Produced Unique Data about the Hibernal Atmosphere above the Central ArcticFor the first time, a German has taken part in a Russian drift expedition and has explored the atmosphere above the central Arctic during the polar night. Jrgen Graeser, a member of the Potsdam Research Unit of the Alfred-Wegener-Institute for Polar and Marine Research in the Helmholtz Association, has just returned home to Germany. As a member of the Russian expedition NP 35 (35. North Pole...

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...

An international team of scientists including Universit© Laval biologist Connie Lovejoy has discovered new life forms in the Arctic Ocean. The team's findings are reported in the January 12 edition of the journal Science. The researchers have discovered a new group of microscopic organisms, which they have baptized "picobiliphytes": pico because of their extremely small size, measured in millionths of a meter, bili because they contain biliproteins, highly fluorescent substances that...

Alfred Lothar Wegener (November 1, 1880 "“ November 2, 1930) was a German scientist, geologist, and meteorologist. He is best known for establishing the theory of the continental drift. His 1915 theory of continental drift surmised that the continents were slowly floating around the Earth. Most of his basis was strictly circumstantial evidence, and further he was not able to exhibit a mechanism for continental drift, which resulted in an unaccepted hypothesis until the 1950s. At that...
