RV Polarstern set off on 27th Antarctic Expedition

25.10.2010
Research vessel Polarstern launches expedition to Antarctic summer – focus on impacts of climate change on oceanic currents, animal and plant world

The research vessel Polarstern sets off on its 27th Antarctic expedition on coming Monday, 25 October. The voyage will consist of four legs separated by port calls in Cape Town (South Africa), Punta Arenas (Chile) and back to Cape Town.

The scientific focal points of the expedition are atmospheric research, oceanography and biology. In addition, the ship will bring supplies to Neumayer Station III, the Dallmann laboratory and the British Rothera station during the expedition. Over 180 researchers from institutes in 15 countries are taking part in the expedition, which will end in Bremerhaven in mid-May 2011.

From Bremerhaven the vessel will first set course for Cape Town, South Africa. The team headed by chief scientist Dr. Karl Bumke from the Leibniz Institute of Marine Sciences (IfM-Geomar) will take advantage of the voyage across the Atlantic to carry out measurements of atmospheric and oceanic properties, determine energy and material fluxes between the ocean and atmosphere and conduct chemical investigations. To study the energy and material fluxes, the scientists will again use instruments installed in the container of the Oceanet project, which was specially developed for applications on freight and research vessels under the management of IfM-Geomar with the Institute of Tropospheric Research in Leipzig.

Furthermore, the scientific team will test an updated system for measuring the seafloor that was installed on board during the dry dock overhaul in Bremerhaven. Dr. Hans-Werner Schenke of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association has been using the so-called Hydrosweep echo sounder for many years, among other things, to draw up nautical charts. Such mapping of the seafloor forms the basis for many other kinds of research work on board. Biologists, for instance, want to put out fish traps on the third leg of the expedition and can determine the most favourable places to do so on the basis of bathymetric data.

The largest living creatures on our planet, the whales, also play a role on the expedition. Researchers of the Oceanic Acoustics working group of the Alfred Wegener Institute want to anchor an acoustic recorder at a depth of around 900 metres at the northern end of the Walvis Ridge west of Namibia shortly before calling at Cape Town. It will record the songs of whales in an area where presumably many species give birth to their young. Since little is known about the migration and breeding grounds of many whales at present, this acoustic method will supply new information on the threatened marine mammals.

In Cape Town a new team of scientists and technicians will put to sea, setting course for the Southern Ocean at the end of November. Among other things, the team predominantly consisting of oceanographers and biologists will study how the Antarctic Ocean changes. Polarstern will additionally bring supplies to Neumayer Station III, the Dallmann laboratory and the British Rothera station and is scheduled to return to Bremerhaven on 20 May 2011.

The Alfred Wegener Institute conducts research in the Arctic, Antarctic and oceans of the high and mid latitudes. It coordinates polar research in Germany and provides major infrastructure to the international scientific community, such as the research icebreaker Polarstern and stations in the Arctic and Antarctic. The Alfred Wegener Institute is one of the sixteen research centres of the Helmholtz Association, the largest scientific organisation in Germany.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
