Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) are setting out with the research vessel Polarstern towards Spitsbergen, to use newly developed equipment in the Arctic Ocean. Autonomous instruments on the seabed, in the water column and in the air will complement the long-term measurements of the deep-sea research group. In this way researchers can analyse the climatic changes in the Arctic and their impact on the fauna in the future with higher temporal and spatial resolution.

Scientific publications involving scientists from the Helmholtz Association should be freely available to the public. This is the intention of a new open access policy recently adopted by the Assembly of Members of Germany’s largest research organisation. According to this policy, publications in the natural sciences should be made available free of charge within six months at the latest; in the humanities and social sciences the deadline is twelve months.

The waters around the Antarctic Peninsula are characterized by significant environmental changes and pronounced natural gradients in physical characteristics. The journal Polar Biology has now dedicated a special issue to this region. The articles in the issue report a wide range of results on the ecology of the Southern Ocean.

On Wednesday, 11 May 2016, the research vessel Polarstern is expected back in its home port of Bremerhaven after a good six months of Antarctic expeditions. In the austral summer, the research vessel of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), penetrated into the southern Weddell Sea as far as the Filchner-Ronne Ice Shelf, where oceanographic and biological work was the focus. In addition, the expedition members provided logistical support for a research camp there.

An international team of researchers headed by scientists from the Alfred Wegener Institute has gained new insights into the carbon dioxide exchange between ocean and atmosphere, thus making a significant contribution to solving one of the great scientific mysteries of the ice ages. In the past 800,000 years of climate history, the transitions from interglacials and ice ages were always accompanied by a significant reduction in the carbon dioxide content in the atmosphere. It then fell from 280 to 180 ppm (parts per million). Where this large amount of…

A unique series of measurements taken over several years in the Antarctic Ocean provide new findings about the daily vertical migration of zooplankton communities: scientists of the Thünen Institute of Sea Fisheries in Hamburg and the Alfred Wegener Institute in Bremerhaven observed changes during the year and between years. The Antarctic zooplankton is the main source of food for many fish and whale species, including the largest mammal in the world, the blue whale.

Sea ice physicists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), are anticipating that the sea ice cover in the Arctic Ocean this summer may shrink to the record low of 2012. The scientists made this projection after evaluating current satellite data about the thickness of the ice cover. The data show that the arctic sea ice was already extraordinarily thin in the summer of 2015. Comparably little new ice formed during the past winter. Today Dr Marcel Nicolaus, expert on sea ice, has presented these findings at…

Researchers of the Alfred Wegener Institute (AWI) will introduce their latest developments in the field of bionic lightweight design at Hannover Messe from 25 to 29 April 2016. Their focus is on the ELiSE lightweight construction method, which uses structures from nature to gain a developmental edge over methods that start from scratch. The industry is currently looking for lightweight reinforcement of complex flat and 3D-components. The AWI researchers have developed and built a holo pyramid that allows them to demonstrate the different procedures to…

An international team of scientists led by the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) have managed to open a new window into the climate history of the Arctic Ocean. Using unique sediment samples from the Lomonosov Ridge, the researchers found that six to ten million years ago the central Arctic was completely ice-free during summer and sea-surface temperature reached values of 4 to 9 degrees Celsius. In spring, autumn and winter, however, the ocean was covered by sea ice of variable extent, the scientists explain…

There is no place in Potsdam for hostility towards foreigners and those seeking refuge, argue the heads of educational and research institutes in Potsdam in an open letter published on 16 March 2016 in the Märkischen Allgemeinen, the Potsdamer Neuesten Nachrichten and other newspapers.
