The head of the Research Unit Potsdam of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association, Prof. Dr. Hans-Wolfgang Hubberten, is the new president of the International Permafrost Association IPA. His appointment took place at the 9th International Conference on Permafrost in Fairbanks, Alaska. Prof. Hubberten will lead the International Permafrost Association for the next four years. During his term in office he will coordinate, among other things, the analysis of the scientific results of the International Polar Year. “In these times of global warming, research on permafrost gains in importance”, explains Hubberten. Permanently frozen areas of the polar region and higher latitudes, which make up about 25% of the earth's surface, a...

A 150-meter ice core pulled from the McCall Glacier in the Arctic National Wildlife Refuge this summer may offer researchers their first quantitative look at up to two centuries of climate change in the region. The core, which is longer than 1 1/2 football fields, is the longest extracted from an arctic glacier in the United States, according to Matt Nolan, an associate professor at the University of Alaska Fairbanks Institute of Northern Engineering who has led research at McCall Glacier for the past six years. The sample spans the entire depth of the glacier and may cover 200 years of history, he said. What we hope is that the climate record will extend back into the Little Ice Age,said Nolan. Up until the late 1800s these glaciers were actually gr...

What's it like to be a research scientist working in the Arctic and Antarctica? In celebration of the International Polar Year, the Exploratorium gave polar scientists cameras and blogs and asked them to document their fieldwork in real time. The result is a groundbreaking Web-based project, Ice Stories: Dispatches from Polar Scientists (http://icestories.exploratorium.edu), where you can follow along on the scientists’ research, ask questions, and share ...

From the mountains to the coast - the Alfred Wegener Institute for Polar and Marine Research based in Bremerhaven inherits the World Radiation Monitoring Center, Switzerland The international archive for radiation data, the World Radiation Monitoring Center (WRMC), provides climate research with high-precision meteorological series of measurements. After a term of fifteen years at the Swiss Federal Institute of Technology Zurich (ETHZ), the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association ensures the successful continuity and enhancements of this unique archive. These data serve the monitoring of the climate, the surveillance of anthropological influence on the earth's surface as well as the improvement of climate forecasts. ...

How will the Arctic sea ice cover develop this summer? ­ Climate scientists from the Alfred Wegener Institute present their own prognosis for the first time Bremerhaven, July 7, 2008. The ice cover in the Arctic Ocean at the end of summer 2008 will lie, with almost 100 per cent probability, below that of the year 2005 ­ the year with the second lowest sea ice extent ever measured. Chances of an equally low value as in the extreme conditions of the year 2007 lie around eight per cent. Climate scientists from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association come to this conclusion in a recent model calculation. They participate with their prognosis in an international scientific contest, in which some of the most renowned institutes on ...

An explorative and research expedition bordering on the inhabited world, in order to investigate the lands and the people living face to face with the ice. How could some hunter groups reach a remote area of Eastern Greenland, known as the Ammassalik District? The answer is not easy, but an Italian scientific expedition is trying to find a possible explanation to the question, while exploring the ice land. The expedition, called Saxum, is led by Gianluca Frinchillucci, director of the Polar Museum “S. Zavatti” of Fermo and responsible for the project CNR-Polarnet “Map of Arctic People”, on his seventh polar explorative mission, and involves several researchers and Italian universities. The initiative falls into the few Italian projects p...

International Award for Information Technology Goes to Research Institutions in the German Federal State of Bremen for the Data Library PANGAEA® The Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association (AWI) and the Center for Marine Environmental Sciences (MARUM) received the 21st Century Achievement Award of the Computerworld Honors Program in the category Environment, which is one of the most prestigious awards in information technology. The award has been granted in response to PANGAEA¹s implementation and successful operation of a unique information system for archiving, publishing and processing of earth system data. Designed to support an integral view on earth, this information system was named after the supercontinent, combining all ...

An international team of researchers was able to provide evidence of explosive volcanism in the deeps of the ice-covered Arctic Ocean for the first time. Researchers from an expedition to the Gakkel Ridge, led by the American Woods Hole Oceanographic Institution (WHOI), report in the current issue of the journal Nature that they discovered, with a specially developed camera, extensive layers of volcanic ash on the seafloor, which indicates a gigantic volcanic eruption. ³Explosive volcanic eruptions on land are nothing unusual and pose a great threat for whole areas,² explains Dr Vera Schlindwein of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association. She participated in the expedition as a geophysicist and has been, together with her tea...

MEDIA ADVISORY JUNE 18TH: POLAR LAND AND LIFE DAY On June 18th, 2008, the International Polar Year 2007-8 (IPY) launches its fifth ‘International Polar Day' focusing on Land and Life: the plants and animals of polar lands and the changing permafrost and hydrologic systems. This Polar Day occurs as hundreds of researchers focus on Arctic environments. It has been timed in conjunction with the Ninth International Conference on Permafrost (NICOP) in Fairbanks, Alaska, and the UNEP TUNZ...

Press release: Bremerhaven, June 9th 2008. Research ice breaker Polarstern of the Alfred Wegener Institute for Polar and Marine Research of the Helmholtz Association puts out to the Arctic on June 12th after three weeks in the dockyards. The expedition of four months length is divided into three stages and leads via the Greenland Sea to Spitsbergen and up to the Fram Strait. The journey through the Northwest Passage up to the East Siberian Sea is planned as the third stage. Two days earlier, on June 10th, the research vessel Heincke leaves the island of Helgoland towards the Orkney Islands. Research is centred on marine biological investigations in the North Atlantic. The emphasis of research of the first part of Polarstern's journey are oceanographic read...
