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)

Symposium in Sisimiut
Arctic Technology Centre at the Technical University of Denmark will throw a symposium on Arctic Solar Energy in Sisimiut, Greenland on the 18th and 19th of September, 2001. The aim is to elucidate solar energy resources and the technological potential, work out an action plan for solar energy, establish a research network and create a basis for coorporation with the aim of increasing the utilization of solar energy. For further information please contact Simon Furbo at Arctic Technology Centre.


North Atlantic right whales float
Scientists studying the diving habits of the North Atlantic right whale say it is more buoyant than other marine mammals and thus more likely to collide with vessels. The whales have to put a lot of swimming effort into diving but can glide quickly upwards. This means that is has more difficulty in diving to escape from dangers on the surface such as an approaching ship. (August 29, 2001)

Bad luck tipped Scott's scales
Two months after reaching the South Pole, Captain Robert F. Scott froze to death just 11 miles from a depot of food and heating oil. His arrival at the pole had been a bitter disappointment because a Norwegian team lead by Roald Amundsen had beaten them by a month. A researcher has used modern climate data to help uncover what went wrong and why. (August 28, 2001)

NASA shuts down 'ozone-probe'
A space probe that has kept track of the hole in the ozone layer over Antarctica will cease operations at the end of next month. NASA has pulled the plug on the project because it costs too much - 10 million US dollars a year - even though the scientists involved in the project are furious. A replacement mission, AURA, is scheduled to be launched in 2003. (August 27, 2001)

Ocean circulation in a million years
Scientists have clocked the speed of global ocean circulation over some one million years, helping to record how the Earth's climate has changed over time. By drilling deep into the ocean bed the scientists recovered 'cores' of material that reveal layers of the sea bed's history. Analyses of these cores show substantial variations in the speed of sea flow originating around Antarctica that are consistent with ice age and warm age climate over the past 1.2 million years.

'Deviant' polar bears in Greenland
There is - and have been - focus on the possible environmental effects of persistant organic pollutants (POP's). Polar bears are in the top of the Arctic food chain and recieve a relatively large amount of POP's through their food. In 1999 DMU's (National Environmental Institute of Denmark) Department of Arctic Environment and Greenland Institute of Natural Resources began a survey on the state of the polar bears in Eastern Greenland. The report is now finished and can be downloaded in Danish only. (24/08-01)

Pole-to-pole view of the weather
For the first time ever scientists can simultaneously measure the height and motion of clouds over Earth from pole to pole, which may improve weather forecasts. The NASA researchers have measured cloud heights from a single satellite, simultaneously measured cloud heights and winds, and done this above Earth's polar regions as well as lower latitudes.

Alaska Range - 150 years of warmth
In the northwest foothills of the Alaska Range, the last 150 years have been warm by historical reckoning, scientists report. They also note, that two other periods of natural climatic warmth occured from 0-300 and 850-1200. The scientists can't say wheater this occuring period of climatic warmth is naturally created.

Environmental atlas on-line
DMU (National Environmental Institute of Denmark) have just published an on-line environmental atlas of the west coast of Greenland. The atlas will secure that e.g. oiling activities are planned so they will have the smallest impact on the environment. In the environmental atlas you can find information on climate, ice, animals, botanics, hunting and fishery. (August 22, 2001)

Cool summer frustrates archeologists
Cool summer weather has caused headaches for archeologists looking for ancient artifacts in the Yukon. They say that ice patches have revealed stone-age tools almost 7000 years old, but the ice patches have not been melting this year because of the low temperatures. (August 21, 2001)

Arctic 'antifreeze'
American chemists claim they have come up with a new 'antifreeze' that could protect crops from frost and allow e.g. soft fruit to be grown in countries where until now it has been too cold for them to survive. The new 'antifreeze' is based on proteins produced naturally in fish who live in polar waters. Their blood contains a chemical called glycoprotein which prevents it from freezing. (August 20, 2001)

Global warming without greenhouse gases
According to Jørgen Peter Steffensen, a Danish scientist from University of Copenhagen, global warming is not necessarily caused by our discharge of greenhouse gases. Actually it is not normal that we have had stabile temperatures for as long as we have. Therefore the global warming we see today is not unusual. (August 20, 2001)

Caribou dead from accident or disease
Recently the Greenland Institute of Natural Resources in Nuuk have recieved reports of caribou dead from accident or disease in the area around the towns of Sisimiut and Kangerlussuaq. The Greenland Institute of Natural Resources have not yet investigated the deaths and can therefore not determine any possible causes. But according to them it is normal that somewhere between four and six percent of a caribou population dies every year. (August 14, 2001)

Cosmic rays linked to ozone depletion
According to two canadian radiation scientists cosmic rays are eating away at the Earth's protective ozone layer. They claim to have evidence of a strong correlation (statistical 'harmony') between cosmic ray intensity and ozone depletion across different levels of the atmosphere and different latitudes. The scientists found evidence for their model in a laboratory simulation of the conditions found in Antarctic clouds. (August 9, 2001)

Brucellosis found in Arctic marine mammals
Canadian authorities have found nine cases of marine brucellosis in the Arctic, Up until recently, the bacteria that causes the disease was only thought to occur in land mammals such as caribou. The brucella bacteria was found in ring and harp seals and a beluga whale. There is a risk that the bacteria will also be found in narwhal and walrus. It is not yet determined if some of Greenland's marine mammals belong to the same population as the infected animals, but no cases of brucellosis have been discovered in Greenland. (August 9, 2001)

'Cold war' over Lake Vostok
Russian scientists have declared that they disagree with western scientists on which method should be used to drill down to the buried Antarctic lake Lake Vostok. The Russians now wish to use a already existing drill hole - and still keep the pristine waters clean. NASA's plan to build a sterile robot has been rejected by the Russians - their own methods are simpler and more reliable. (August 9, 2001)

Solar storms destroy ozone
A new study from NASA confirms a long-held theory that large solar storms rain protons (electrically charged particles) down on Earth's atmosphere and deplete the upper-level ozone for weeks to months thereafter. When protons like these bombard the upper atmosphere, they break up molecules of gases like nitrogen and water vapor, and once freed, those atoms react with ozone molecules and reduce the layer.

Solar energy in Greenland
Surveys from Centre for Arctic Technology under DTU (Technical University of Denmark) have shown that Greenland, because of it's clean air can benefit up to 40 percent more from solar energy than Denmark can. Even in the dark Greenland can use alternative energy because of the light coming from the snow, and students in the town of Sisimiut are kept warm during the winter using the rays of the sun.

Ridge tells how Earth's crust is formed
Right now research teams are leaving for The Arctic Ocean on board the two icebreakers Healy and Polarstern. The purpose of the trip is to bring home pieces of volcanic rock from the sea floor along Gakkel Ridge hidden three miles beneath the ocean surface. The researchers believe that the rock contains information that can help them fill the gap in their knowledge of how the Earth's crust forms. The Gakkel Ridge is an ultra slow spreading ridge, meaning it is spreading less than one centimeter a year. (August 1, 2001)
