Pollutants travel thousands of kilometers
It is commonly known, that certain pollutants can travel through air - but how far? Geoscientists found that pollutants can travel thousands of kilometers through air and can lead to deposition long distances from where thay were produced or used. For example, high levels of pesticides from afar are present in Arctic beluga whales. (September 24, 2001)

Classification of sea ice
In August 2000 DMI (Danish Meteorological Survey) started a project with the purpose to improve the mapping of sea ice around Greenland using various satellite data. Data have just been examined and analyzed, and the results will be presented at an international conference held in France from September 20th. (September 24, 2001)

El Niño & La Niña rearrange sea ice
Scientists have been mystified by observations that when sea ice on the one side of Antarctica recedes, it advances farther out on the other side of the continent. NASA findings suggest for the first time that this is the result of El Niños and La Niñas driving changes in the subtropical jet stream, which then alter the path of storms that move sea ice around Antarctica.

'Long waves' ozone hole trigger
NASA researchers using 22 years of satellite-derived data have confirmed a theory that the strength of 'long waves', bands of atmospheric energy that circle the Earth, regulate the temperatures in the upper atmosphere of the Arctic, and play a role in controlling ozone losses in the stratosphere.

The ozone hole above Antarctica
According to NASA (National Aeronautics and Space Administration) scientists this year's ozone hole above Antarctica is already larger than Antarctica itself. In 2000, the ozone hole was the largest on record, three times larger in area than the entire land mass of the United States. But what causes these holes? Read a background article on the chemical reactions that proceed the formation of the yearly ozone hole above Antarctica. (September 19, 2001)

Ozone layer threatened by new chemicals
A range of new chemicals, used in everything from fire extinguishers to cleaning fluids, are appearing on the market to the concern of scientists studying the ozone layer. UNEP (United Nations Environment Programme) has estimated that the oxone layer and the ozone hole over Antarctica will recover by 2050. But the emergence of these new chemicals has triggered concern that this recovery date may be significantly delayed. (September 17, 2001)

Around Greenland in four years
In May 1997 Lonnie Dupre and John Hoelscher began their adventurous trip around Greenland. Now - after travelling 10,500 km on dog sledges and almost 5000 kilometers in kayaks - they have reached their goal. The two explorers have travelled the traditionel Inuit way to pay their respects to Inuit culture and to get up close and personal with nature. (September 10, 2001)

Arctic without ice in Ice Age
Imagine the Arctic Circle in the Ice Age - white and cold. No, think again! Archeologists say a recent discovery of animal bones, stone tools and fossils indicate humans lived there more than 40,000 years ago, and the region then may not have been covered in ice at all. The findings suggest that the northeast must have been relatively dry and ice free in that period of the Ice Age. (September 10, 2001)

Online debate on Antarctic climate
Scientist Susan Solomon has just published a book that sheds light on the effect that the Antarctic climate had on the tragic story of Sir Ernest Shackleton. Monday the 11th of September NSF will broadcast an online paneldiscussion about the difficulties of predicting and modelling the Antarctic weather. Participating will be Susan Solomon (NOAA), Charles Stearns (University of Wisconsin) and several others. See the NSF press release. (September 7, 2001)

An Antarctic warming puzzle
UK scientists say parts of Antarctica have recently been warming much faster than most of the rest of the Earth. They suggest three possible mechanisms that may account for what is happening: Changing ocean currents, reducing sea-ice or a unique sea-ice-atmosphere feedback. But the scientists can not identify a cause with certainty. (September 7, 2001)

Grant for North Atlantic vikings
Thanks to a grant from the UK Leverhulme Trust, researchers from University of Aberdeen and CUNY (City University of New York) are going to shed light over what happens socially and environmentally when a group of people - in this case the vikings in Greenland, Iceland and the Pharoah Islands - colonize 'pristine' landscapes. Using fossil evidence and historical documents the researchers will look into the long-term effects of settlement in environmentally sensitive areas. (September 6, 2001)

Evidence of ancient Arctic campers
Primitive stone tools and other artifacts discovered close to the Arctic circle in the desolate far north of Russia indicate a band of hunters set up camp there almost 40,000 years ago - far earlier than previously thought, researchers report. It was previously believed that humans had not reached this far north until the final stage of the last Ice Age some 13,000 - 14,000 years ago. (September 6, 2001)

Icefish holds genetic answers
Research on the genetic make-up of Antarctic icefish can help scientists solve genetic puzzles related to blood diseases in humans such as anemias and leukemia. The Antarctic icefish (in latin known as Chaenichthys) is the only vertebrate taxonomic group that produces neither red blood cells nor hemoglobin. This means that the icefish lives without a normal oxygen transport system. (September 4, 2001)

This years hole in the ozone layer
During the last week of August the yearly hole in the ozone layer above Antarctica has formed. September 1st the hole covered 23 million square kilometers - or 2,5 times the size of USA! That is only exceeded by last years hole in the Antarctic ozone layer which covered an area of 28 million square kilometers.

Rock and ice crushes identically
Observations of ice in the polar regions now lead researchers to believe that most brittle materials, like rock and ice, crumble or fail in the same manner. It is apparantly a specific type of cracking mechanism that leads to collapse. As ice is compressed, cracks within it slide together and link up, eventually causing the ice to fail. The research shows that this mechanism is also present in other brittle materials and can help predict how they will fail and why. (September 3, 2001)

Mercury falling into food chain
New research shows, that the sudden burst of sunlight after long polar winters drives chemicals in sea salt to react with normally inert mercury vapour in the air depositing it onto snow. On melting this snow injects a pulse of mercury into the Arctic ecosystem. The mercury becomes concentrated as it passes through the food chain. Levels are particularly high in Arctic fish and mammals and in the Inuit people who eat them. See also our article in Polarfronten on environmental toxins in the Inuit of North Eastern Greenland.

Seal pups recognise mum's voice
French scientists have discovered that pups of the Antarctic fur seal are able to recognise their mothers voices as early as two days after birth. The mother needs to hunt for fish a few days after the pup is born. She delays her first fishing trip until after the pup has learnt her voice. When she returns, after a few weeks at sea, she locates her pup among many others in the rookery by calling out. (August 30, 2001)

Permafrost in 3 million years
In Yukon, Canada scientists have discovered evidence of North America's oldest permafrost. A small pile of discoloured earth is the proof of permafrost for as long as 3 million years ago. The findings can help scientists to a better understanding of the Ice Age of Yukon and Alaska, and help them predict the impacts of future climate change. (August 30, 2001)
