7600 scientist from 36 nations have gained insights into the polar oceans aboard Polarstern, facilitating our current understanding of the earth as a system. Polarstern provides ideal working conditions for international and interdisciplinary research teams and offers safe transport in polar seas.
Currently, Polarstern is on her way to the Antarctic as part of the International Polar Year 2007/08. The birthday celebration for Polarstern will take place on November 28 at the Museum of Natural History in Berlin, and will include a special address by Chancellor Dr Angela Merkel.
The international research community owes a vast amount of knowledge to the operation of Polarstern, e.g. concerning past climate and the largely unexplored deep sea. The largest German research vessel was funded by the then Federal Ministry of Education and Research, and is operated by the Alfred Wegener Institute for Polar and Marine Research. "For 25 years, expeditions aboard Polarstern have been producing scientific results which have significantly advanced our understanding of important parts of the earth as a system", says Prof Dr Karin Lochte, Director of the Alfred Wegener Institute.
Polarstern expeditions are designed as international and interdisciplinary ventures in order to enhance insights into the polar regions through optimal scientific exchange and data gain. Polarstern can accommodate up to 55 scientists, who, aside from being provided with a bunk, have access to modern laboratories, aquaria and measuring equipment, but are also able to bring their own instruments or work around the clock. During extended research voyages to the polar regions, Polarstern must be entirely self-sufficient, with the crew being able to carry out even complicated repairs independently. Polarstern not only represents a floating laboratory, it also supplies Neumayer Station in the Antarctic, which is operated year round, with food, materials and fuel.Polar research is climate research
In order to facilitate participation by the general public and future young scientists in polar research, individual Polarstern voyages are occasionally accompanied by media representatives, teachers and artists. University students and PhD candidates regularly join Polarstern in order to get to know the practical aspects of polar research and to collect important data for diploma and doctoral research.
Both anchored and drifting recording platforms, deployed during expeditions in the Arctic and Southern Oceans, have been providing multi-year data records of salinity, temperature and currents, including during winter and from below the sea ice. Oceanographers at the Alfred Wegener Institute have been using these data to examine the effects of current climate change on polar oceans and broader global climate developments. The operation of such observation systems requires continual maintenance and a reliable polar research programme.
The winter expeditions attracted particular attention. Usually, Polarstern travels to the Arctic during the European (i.e. Arctic) summer and spends her winters (austral summers) in the Antarctic. However, several research expeditions were also carried out during the polar winter seasons. These investigations pose very high technical demands, but are essential for observations of full annual cycles in polar environments. 2005/2006 was the last time Polarstern spent a full year in the Antarctic to explore the development of sea ice and associated species communities. One important component of polar animal life is the Antarctic krill. These crustaceans not only represent the most significant food source for many marine mammals, but also have much commercial potential.
Geoscientists owe their current knowledge about the origin of the polar oceans to seismic investigations aboard Polarstern. The opening and closing of ocean basins severely influenced the development of life, as well as climate, during the various geological periods on Earth. Sediment cores obtained from aboard Polarstern, provide insights into the climate history of the planet.Polarstern during the International Polar Year 2007/08
On October 26, 2007, Polarstern left Bremerhaven for Cape Town. During this voyage, marine biologists have been studying the species composition and distribution of small animals drifting in the water, the so-called zooplankton. The microscopic organisms form the dietary basis of many fishes, thus representing an essential component of marine food webs in the ocean. Within the framework of the project 'Census of Marine Zooplankton', the marine biologists are expecting to discover numerous new species of plankton. After a brief stop in Cape Town, Polarstern will start heading towards Antarctica on November 28, 2007.Polarstern - 25 years of research in Arctic and Antarctic

For the first time, an international team of scientists based in Regensburg, Germany, has recorded the orbitals of single molecules in different charge states in a novel type of microscopy. The research findings are published under the title “Mapping orbital changes upon electron transfer with tunneling microscopy on insulators” in the prestigious journal “Nature”.

Physicists from the University of Basel have developed a new method to examine the elasticity and binding properties of DNA molecules on a surface at extremely low temperatures. With a combination of cryo-force spectroscopy and computer simulations, they were able to show that DNA molecules behave like a chain of small coil springs. The researchers reported their findings in Nature Communications.
DNA is not only a popular research topic because it contains the blueprint for life – it can also be used to produce tiny components for technical applications.
