  You can´t get any “higher”: on 22 August 2011 at exactly 9.42 a.m. the research icebreaker Polarstern of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association reaches the North Pole. The aim of the current expedition is to document changes in the far north. Thus, the researchers on board are conducting an extensive investigation program in the water, ice and air at the northernmost point on the Earth. The little sea ice cover makes...

The research aircraft Polar 5 of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association returned to Bremerhaven from a six-week expedition in the high Arctic on May 6. Joint flights with aircraft of the European and American space agencies (ESA and NASA) were a novelty in sea ice research. Simultaneous measurements with a large number of sensors on three planes underneath the CryoSat-2 satellite led to unique data records. Furthermore, the international team...

International studies describe current state of the Arctic coasts The coastline in Arctic regions reacts to climate change with increased erosion and retreats by half a meter per year on average. This means substantial changes for Arctic ecosystems near the coast and the population living there. A consortium of more than thirty scientists from ten countries, including researchers from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association and from the...

The freshwater content of the upper Arctic Ocean has increased by about 20 percent since the 1990s. This corresponds to a rise of approx. 8,400 cubic kilometers and has the same magnitude as the volume of freshwater annually exported on average from this marine region in liquid or frozen form. This result  is published by researchers of the Alfred Wegener Institute in the journal Deep-Sea Research. The freshwater content in the layer of the Arctic Ocean near the surface controls whether...

The extent of the sea ice in the Arctic will reach its annual minimum in September. Forecasts indicate that it will not be as low as in 2007, the year of the smallest area covered by sea ice since satellites started recording such data. Nevertheless, sea ice physicists at the Alfred Wegener Institute are concerned about the long-term equilibrium in the Arctic Ocean. They have indications that the mass of sea ice is dwindling because its thickness is declining. To substantiate this, they are...

Autonomous underwater vehicle of the Alfred Wegener Institute dives under the Arctic ice for the first time The Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association for the first time sent its Autonomous Underwater Vehicle (AUV) on an under-ice mission at about 79° North. The four-metre-long, torpedo shaped underwater vehicle was deployed from the research icebreaker Polarstern under heavy pack ice. The vehicle was subsequently recovered by helicopter. "We...

Researchers from German Alfred Wegener Institute and KlimaCampus present forecasts on September minimum A critical minimum for Arctic sea ice can also be expected for late summer 2010. Scientists from the German "Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association (AWI)" in Bremerhaven and from "KlimaCampus" of the University of Hamburg have now published their projections in the current Sea Ice Outlook. The online publication compares the forecasts on ice...

Elephant Seals send Scientific Data from the Antarctic to Bremerhaven via Satellite Transmitter "Gustavo" is an imposing bull always in search of the best feeding grounds. The elephant seal weighing 3 tons and measuring 4 meters in length belongs to a group of 14 animals that serve researchers of the Alfred Wegener Institute as scientific assistants since recently. At the beginning of the Antarctic winter "“ from mid-March to the end of April "“ the mighty elephant seal bulls were...

Scientists from the Alfred Wegener Institute present first results of a new measurement method in Antarctica Currently the yearly General Assembly of the European Geological Union takes place in Vienna, Austria. Dr. Olaf Eisen from the German Alfred Wegener Institute presents results from an environmentally friendly measurement method that he and his colleagues used on an Antarctic ice-shelf for the first time in early 2010. It supplies data that are input to models for the ice mass balance...

The first season of the international drilling project NEEM (North Greenland Eemian Ice Drilling) in north-western Greenland was completed at August 20th. A research team, with the participation of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association, has drilled an ice core of altogether 1757.87 m length on the Greenland inland ice within 110 days. It is expected to contain data on climate history of about 38.000 years. The oldest ice comes from a period...

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...
