New insight into accelerating summer ice melt on the Antarctic Peninsula
A new 1000-year Antarctic Peninsula climate reconstruction shows that summer ice melting has intensified almost ten-fold, and mostly since the mid 20th Century. Summer ice melt affects the stability of Antarctic ice shelves and glaciers. View More (2013-04-15)
Marine animals suggest evidence for a trans-Antarctic seaway
A tiny marine filter-feeder, that anchors itself to the sea bed, offers new clues to scientists studying the stability of the West Antarctic Ice Sheet - a region that is thought to be vulnerable to collapse. View More (2010-08-31)
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)
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)
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 irreparable damage. Between 1997 and 2001, Dutch... View More (2001-11-26)
Ice Shelves Disappearing on Antarctic Peninsula
Ice shelves are retreating in the southern section of the Antarctic Peninsula due to climate change. This could result in glacier retreat and sea-level rise if warming continues, threatening coastal communities and low-lying islands worldwide. View More (2010-02-23)
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)
Recent climate, glacier changes in Antarctica at the 'upper bound' of normal
In the last few decades, glaciers at the edge of the icy continent of Antarctica have been thinning, and research has shown the rate of thinning has accelerated and contributed significantly to sea level rise. View More (2013-04-15)
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 equipped with an auxiliary steam engine in... View More (2005-03-10)
3 scientific expeditions seek treasure under the ice in the Frozen Continent
In a modern iteration of the great age of Antarctic exploration of the 19th and 20th centuries, three teams of scientists are rushing to reach not the South Pole like Roald Amundsen, Robert Falcon Scott and Ernest Shackleton, but lakes deep below the surface of the Frozen Continent believed to hold scientific treasures.

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 to the Antarctic. David Barnes of the British... View More (2002-04-23)
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 Antarctica. View More (2005-05-19)
UIC scientists find ancient microbes in salty, ice-sealed Antarctic lake
Shedding light on the limits of life in extreme environments, scientists have discovered abundant and diverse metabolically active bacteria in the brine of an Antarctic lake sealed under more than 65 feet of ice. View More (2012-11-27)
Climate changes are linked between Greenland and the Antarctic
Even if climate records from Greenland and Antarctic ice cores look different, climate of Artic and Antarctic are directly linked. Investigations of an Antarctic ice core indicate a principle connection between both hemispheres by a 'bipolar seesaw'. View More (2006-11-10)
New evidence shows Antarctica has warmed in last 150 years
Despite recent indications that Antarctica cooled considerably during the 1990s, new research suggests that the world's iciest continent has been getting gradually warmer for the last 150 years, a trend not identifiable in the short meteorological records and masked at the end of the 20th century by large temperature variations.

Genes hold secret of survival of Antarctic 'antifreeze fish'
A genetic study of a fish that lives in the icy waters off Antarctica sheds light on the adaptations that enable it to survive in one of the harshest environments on the planet. View More (2008-10-17)
Female Antarctic seals give cold shoulder to local males
Female Antarctic fur seals will travel across a colony to actively seek males which are genetically diverse and unrelated, rather than mate with local dominant males. View More (2007-02-08)
El Nino events affect whale breeding
A thirty-year study by an international team of scientists found a strong relationship between breeding success of whales in the South Atlantic and El Nino in the western Pacific. View More (2006-01-11)
Antarctic ice sheet losing mass, says University of Colorado study
University of Colorado at Boulder researchers have used data from a pair of NASA satellites orbiting Earth in tandem to determine that the Antarctic ice sheet, which harbors 90 percent of Earth's ice, has lost significant mass in recent years. View More (2006-03-03)
