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 ...

From April to September 2008, University of Alaska Fairbanks researcher Matt Nolan is living on McCall Glacier in Northern Alaska with his wife, son and fellow researchers, subjecting the glacier to a battery of tests... and blogging the process. Because McCall Glacier is so remote, he’s only able to send his blog entries by plane every few weeks or so. We’ve just received — and posted — the most recent batch. You can access all of Matt’s posts via this link. What makes Matt’s posts so interesting is that he uses an assortment of multimedia tools to get his message across. Not “just” text and photos, but also video (posted to YouTube and embedded here on IPY.org)...

The Arctic field season is now in full flow.. IPY researchers are busy in Northern Canada, Alaska, Greenland, Russia, Scandinavia, and the Arctic Ocean. They are also, like their Antarctic colleagues, committed to public outreach. So where are the stories? Well.. they're just starting to come in, as the researchers return to a more-connected world. This image shows BAS personnel Crispin Day (left), Richard Hindmarsh (centre) and Fabien Gillet (right) who went to NSF Summit Station in Greenland to deploy the BAS phase-sensitive radar (pRES). This measures deformation in ice, and the team will exploit a glaciological phenomenon known as the "Raymond Effect" to achieve a high-accuracy determination of the viscosity (stickiness) of ice. Knowledge of this is essential in predi...

Sooty particles emitted during the incomplete combustion of fossil fuels (petroleum, coal), biofuels, and biomass (wood, animal dung, etc.) can do more than just create unsightly pollution and provoke respiratory problems. Known within the scientific community as black carbon, research and modelling conducted in recent years shows that this dark-coloured aerosol has been playing a significant role in climate warming through its absorption of solar radiation. Its impact is heaviest in the cryosphere, where its presence can reduce snow albedo and can lead to faster melting of snow on land and on sea ice. ...

There are three graduate students on this trip: Darek Ignatiuk, Ryo Kusaka, and Jason Geck. Our project is part of the IPY Glaciodyn effort, an international project focusing on the role of arctic glaciers in the global system, involving more than a dozen countries. To facilitate exchange of ideas and comparisons between glacier systems, as part of this larger project we try to exchange personnel on field trips whenever possible, and Darek and Ryo are part of that exchange. Darek is from Poland and is a graduate student at the University of Silesia in Katowice, studying under Dr. Jacek Jania. His interests are broadly based but have an emphasis on surface energy and mass balance. His primary glacier field work has been in Svalbard, working on glaciers around the Polish Polar...

With the deep drilling finished, it was time to start transitioning fully into our process studies on McCall Glacier. What we are particularly interested in this year is the fate of surface snow melt. How much of this drips into the snow pack and refreezes? How much reaches the bottom the glacier and helps the glacier move faster? To answer these questions we are planning to track this meltwater throughout the year. We will do this by repeatedly coring the upper 10 meters or so of snow in the accumulation areas, and by studying the stream at the outlet of the glacier. This is logistically complicated because these two areas are at opposite ends of the glacier – the very top and the very bottom. Separated by seven kilometers, this means a lot of hiking back and forth to try to watch both ...

Jason and I were near our second camp location installing a continuously-recording D-GPS system on the ice when we heard Darek’s voice on the radio “We finished!” The third and final hole of this trip was completed. We quickly finished hooking up the wires and cables for the GPS system and confirmed it was working, then headed up to lower cirque to drop down our thermistor string. Yesterday had been largely a bust in terms of drilling, as well as most other things. The weather continued to remain snowy and windy, and conditions on the glacier were poor for travel as the snow was deep, the trail drifted over, and visibility was frequently zero. I used one break in the weather to pack down the skiway, but that was the extent of my travel away from camp. The drill team tr...
