As predicted by all IPCC models, Arctic sea ice will most likely disappear during summers in the near future. However, it seems like this is going to happen much sooner than models predicted, as pointed out by recent observations and data reanalysis undertaken during IPY and the Damocles Integrated Project. On February 25, 2009, there will be a celebration in Geneva, Switzerland to officially close the 4th IPY that started on March 1st 2007 in Paris, France. It is not a surprise that one of the main topics of this 4th IPY was climate change, since the polar regions play a very important role in Earth's climate. This role is magnified by the combined effect of two main processes: one is due to the presence of greenhouse gases in the atmosphere trapping longwave solar radiat...

Recent observations of Arctic Ocean outflow in the Fram Strait suggest that freshwater is piling up in the Arctic Ocean. A change in wind direction could release the largest amount of freshwater through Fram Strait ever recorded. Photo: Rudi Caeyers The freshwater transport from the Arctic to lower latitudes is one of the main ways of the Arctic to interact with the global climate system. The effect of such a release of freshwater depends on the final magnitude and nature of the release. “The effects this release will have on the climate processes are in the focus of ongoing res...

As part of the field season of the 2007 International Polar Year, the Zackenberg research station was kept open two months longer than normal to host the project: Influence of Snow and Ice on the Winter Functioning and Annual Carbon Balance of a High-Arctic Ecosystem (ISICaB). This opening gave us a chance to observe autumn and early-winter carbon fluxes. Six automated chambers provided methane flux measurements once per hour, day and night in a typical fen area. At the end of the growing season, emissions decreased during September until they reached the presumed low winter emission level. However, at the onset of soil freeze-in, a substantial increase in emissions was observed and was sustained for several weeks, corresponding to the time required for a complete freeze-in of the entire a...

The Arctic has always been a difficult place to do any extensive monitoring and data collection. Until recently, there have only been a limited number of projects that have taken any significant, long-term, and coordinated observations of the Arctic Ocean and adjacent bodies of water. This is due in part to the extensive sea ice cover that persists over Arctic waters for a good part of the year, which makes it difficult to conduct ship surveys or deploy weather buoys and moorings to measure deep water currents. Arctic ROOS (Regional Ocean...

Permafrost research makes you happy Photo: Dominik Langhamer Thanks to Hanne H. Christiansen from UNIS for the text of this clog, sent from the field. To follow their adventures or get more details about the course have a look at www.tspnorway.com ! In just one long day 10 m of mainly frozen sediment cores were collected from 4 different parts of the landscape here in NE Greenland using hand held drilling machines. Thermistor strings were installed down to 3.2 m below the terrain surface in the deepest hole. This was done by the Interna...

In a period of 48 hours, our weather has changed three times, from (almost) Miami Beach-type temperatures, to driving snow, and back to sun late this afternoon. Lingering morning snow prevented a survey of the region by helicopter. Instead, time on the ground gave the scientists an opportunity to finish building their instrument towers. We also have started to pack camp, stacking trash bags and tools about 200 feet from our tent in preparation for our scheduled helicopter ride off the ice tomorrow morning. There is still no word about Sarah Das’s dye, which she poured in a moulin several days ago to track drained lake water flowing from the base of the ice sheet to the coast. Our source on the coast south of Ilulissat (Sarah’s graduate student, Maya Bhatia) said recent s...

The Arctic Social Indicators (ASI) project is an IPY project and is following up on the activities of the Arctic Human Development Report (AHDR), and is initiated by the Stefansson Arctic Institute, Akureyri, Iceland, which also hosts the secretariat. ASI has been endorsed by the Arctic Council.

Gallery SPOT features the painter Pierre Auzias, the photographer Martin Lehmann and the filmmaker Bertrand Lozay in the art installation: Slush! Artistic reflections on the increasing global temperature in Greenland Launching Saturday, March 1. From 2 - 5 pm. The exhibition runs to March 30, 2008. The exhibition operates in two levels, connecting both to the physical gallery space as well as to the social and psychological space of Greenland. By embracing a variety of different media and symbolic effects, the exhibition demonstrates current identity and environmental issues in Greenland. During the opening show Pierre Auzias is working in an interdisciplinary manner, creating a site specific installation. Auzias´...

PRESS RELEASE North3 Goes Live on the Internet From: Canadian Embassy Heads of Mission: Ralph Lysyshyn (MOSCOW) Anna Blauveldt (REYKJAVIK) Scott Fraser (HELSINKI) Fredericka Gregory (COPENHAGEN) Jillian Stirk (OSLO) and Alexandra Volkoff (STOCKHOLM) Date: 2008-01-10 Summary: To mark the International Polar Year, Canada's circumpolar embassies have launched an internet outreach project to engage northern youth. Canadian embassies in COPENHAGEN, HELSINKI, MOSCOW, OSLO, REYKJAVIK and STOCKHOLM are pleased to announce that North3 is now on the internet (www.ookpik.org/north3). These missions have collaborated...

This week, a Nordic tissue paper company called Metsa? Tissue, launched it's campaign announcing a one million kronor donation to IPY. The majority of these funds were directed to the IPY project, KINNVIKA , but about one third was used to support the first meeting of the International Youth Steering Committee and Association of Polar Early Career Scientists. The meeting was essential for bringing together key volunteers who have been working hard over the last two years to establish an international network of polar researchers, and aspiring polar researchers, between the undergraduate and early-career stages of their careers. At the meeting, the two groups agreed to merge under the common title: APECS, Association of Polar E...
