Food shortages threaten Antarctic wildlife
Antarctic whales, seals and penguins could be threatened by food shortages in the Southern Ocean. Numbers of Antarctic krill (Euphausia superba), a shrimp-like crustacean at the heart of the food chain, are declining. The most likely explanation is a dramatic decline in sea-ice. The results are published this week in the journal Nature. view more (2004-11-01)
Unmanned aerial vehicles mark robotic first for British Antarctic Survey
Scientists at British Antarctic Survey (BAS) in collaboration with the Technical University of Braunschweig (TUBS), Germany have completed the first ever series of flights by autonomous unmanned aerial vehicles (UAVs) in Antarctica. view more (2008-03-19)
Antarctic krill provide carbon sink in Southern Ocean
New research on Antarctic krill (Euphausia superba), a shrimp-like animal at the heart of the Southern Ocean food chain, reveals behaviour that shows that they absorb and transfer more carbon from the Earth's surface than was previously understood. view more (2006-02-07)
New Era for Norwegian Antarctic Research
The framework conditions for Norwegian research in Antarctica are completely changing. The Norwegian summer station, Troll, will be a year-round station, and the airstrip beside Troll will soon accommodate intercontinental flights. This will have enormous consequences for Norwegian research. From February 2005, year-round operations at the... view more... (2004-08-04)
Satellite spies on doomed Antarctic ice shelf
Satellite images have revealed the collapse of Larsen B ice shelf on the Antarctic Peninsula fulfilling predictions made by British Antarctic Survey (BAS) scientists. The collapse of the 3250 km2 ice shelf is the latest drama in a region of Antarctica that has experienced unprecedented warming over the last 50 years. Earlier this month Ted Scambos... view more...

Hibernation-like behavior in Antarctic fish -- on ice for winter
Scientists have discovered an Antarctic fish species that adopts a winter survival strategy similar to hibernation. Reporting this week in the journal PLoS ONE, the online journal from the Public Library of Science, scientists from British Antarctic Survey (BAS) and the University of Birmingham reveal, for the first time, that the Antarctic 'cod'... view more...

UK Princess sees oldest ice on earth
Princess Anne, currently visiting Antarctica, was today given a gift of ice that is 50000 years old. It came from an ice core - a cylinder of ice drilled from the Antarctic ice sheet - drilled by the European Project for Ice Coring in Antarctica (EPICA). EPICA, a consortium of 10 European nations, is drilling two ice cores in Antarctica, in order... view more... (2002-02-08)
The Risk Of Antarctic Ice Sheet Collapse
There has been much speculation that global warming may cause sea levels to rise due to the melting of ice sheets. For the first time scientists have worked out the likelihood of Antarctic ice sheet collapse using engineering risk-analysis techniques. They conclude that there is a 5% chance of major sea level rise (up to 1 metre) in the next... view more... (2001-12-28)
In the Cornucopia of the European Project of Ice Coring in Antarctica: the oldest Antarctic ice core
On Tuesday 21th of December 2004 a European team involved in Epica (European Project for Ice Coring in Antarctica) reached the drilling depth of 3270.2, which is five meters above the bedrock at Dome C, on the central plateau of the east Antarctic ice sheet. The ice is melting at the bedrock and it has been decided to stop at this depth to avoid... view more... (2005-01-13)
Overall Antarctic snowfall hasn't changed in 50 years
The most precise record of Antarctic snowfall ever generated shows there has been no real increase in precipitation over the southernmost continent in the past half-century, even though most computer models assessing global climate change call for an increase in Antarctic precipitation as atmospheric temperatures rise. view more (2006-08-11)
Antarctica glacier retreat creates new carbon dioxide store
Large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula. view more (2009-11-10)
New Antarctic seabed sonar images reveal clues to sea-level rise
Motorway-sized troughs and channels carved into Antarctica's continental shelves by glaciers thousands of years ago could help scientists to predict future sea-level rise. view more (2009-05-05)
NASA Study Finds Clock Ticking Slower On Ozone Hole Recovery
The Antarctic ozone hole's recovery is running late. According to a new NASA study, the full return of the protective ozone over the South Pole will take nearly 20 years longer than scientists previously expected. view more (2006-06-30)
Warming oceans threaten Antarctic glaciers
Scientists have identified four Antarctic glaciers that pose a threat to future sea levels using satellite observations, according to a study published in the journal Science. view more (2007-03-16)
Antarctic plants repair themselves
Dutch researchers funded by NWO have studied the effects of the hole in the ozone layer on the vegetation in Antarctica. The repair mechanisms of lichens and mosses appear to be effective even at low temperatures. Nevertheless, the ecology of the Antarctic is still under threat. The rise in temperature caused by the greenhouse effect is doing... view more... (2001-11-26)
New clues to ozone depletion
Laerge quantities of ozone-depleting chemicals have been discovered in the Antarctic atmosphere by researchers from the University of Leeds, the University of East Anglia, and the British Antarctic Survey. view more (2007-07-27)
175th birthday of the German polar explorer Eduard Dallmann
2005 marks the 175th birthday of Eduard Dallmann, a pioneer of German Antarctic research. Through his expeditions, Dallmann, who was born in Blumenthal (now part of Bremen) contributed significantly to the knowledge about Antarctica. He named numerous island groups and straits. From 1873 onwards, the 'Grönland', one of the first sailing ships... view more... (2005-03-10)
Discarded human debris threatens global biodiversity
Discarded human debris is encouraging colonization of exotic marine animals in the world`s oceans and threatening global biodiversity, particularly in the Southern Ocean. The findings, reported in this week`s NATURE, are based on a 10-year study of human litter (mostly plastic) washed ashore on 30 remote islands around the globe, from the Arctic... view more...

Antarctica - an awakening giant?
The crucial role that Antarctica plays in global climate change and its future contribution to sea-level rise was highlighted today by Professor Chris Rapley, Director of British Antarctic Survey (BAS). Speaking at an international convention on climate change in Bonn, Germany* he presented a summary of the latest scientific results from... view more... (2005-05-19)
