The origin of the neurotoxin azaspiracid has finally been identified after a search for more than a decade. The azaspiracid toxin group can cause severe poisoning in human consumers of mussels after being enriched in the shellfish tissues. The scientific periodical European Journal of Phycology reports in its current issue (Vol. 44/1: p. 63-79) that a tiny algal species, the dinoflagellate Azadinium spinosum, is responsible. Researchers from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association have isolated and…

The ice cap of the Western Antarctic has apparently deglaciated completely many times three to five million years ago. The periodical nature reports in its current issue (vol. 458) that these regular deglaciation phases have been caused by changes in the tilt of the Earth’s rotational axis in times of increased atmospheric carbon dioxide concentrations. This is the result of a sediment core drilled under German participation below the Antarctic Ross ice shelf in the framework of the international drilling project ANDRILL (ANtarctic geological DRILLing).

The International Polar Year 2007/2008 nears its end. Today, about 120 people celebrate two years of intense and internationally coordinated scientific campaigns in earth’s two Polar Regions in the Klimahaus Bremerhaven. During the German closing event of the International Polar Year 2007/2008, they did not only look back upon new insights and successful German contributions. The researchers from all over Germany emphasized the future importance of Polar research.

The Federal Minister for Education and Research, Dr Annette Schavan, inaugurated Neumayer Station III today at noontime. The new German research facility thereby starts its scientific operation. It is located 6.5 km south of the old Neumayer Station on the Ekström ice shelf in Dronning Maud Land in the Antarctic. The station serves as a base for scientific observatories as well as logistic centre for inland expeditions and polar aircraft.

The Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association can conduct the ongoing Polarstern expedition „LOHAFEX”. Independent scientific and legal reviews sought by the Federal Ministry of Education and Research and the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety concluded that the iron fertilisation experiment LOHAFEX is neither against environmental standards nor the international law in force. There are thus no ecological and legal reasons to further suspend the iron fertilisation…

The new German research base Neumayer Station III can be seen in its final form for the very first time. A new milestone in the construction of the station is reached after the successful completion of the outer shell. The Shell protects the upper two floors - which are comprised of container modules - from exterior weather conditions.

The German research vessel Polarstern is currently on its way to the Southwest Atlantic Sector of the Southern Ocean. The team of 48 scientists (30 from India) on board left Cape Town on 7th January to carry out the Indo-German iron fertilization experiment LOHAFEX (LOHA is Hindi for iron, FEX stands for Fertilization EXperiment).

The Alfred Wegener Institute for Polar and Marine Research and the engineering company Wärtsilä Ship Design Germany presented the technical design of the European Research Icebreaker „Aurora Borealis“ in Berlin. As a combination of a heavy icebreaker, a scientific drilling ship and a multi-purpose research platform it is planned to operate year-round in all polar waters.

Changes to marine ecosystems caused by climatic conditions show how closely physiological and ecological processes are intertwined. This is described by Prof. Dr. Hans-Otto Pörtner, physiological ecologist at the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association, in the current issue of the periodical Science.
