NASA flies to Antarctica for largest airborne polar ice survey
NASA begins a series of flights Oct. 15 to study changes to Antarctica's sea ice, glaciers and ice sheets. The flights are part of Operation Ice Bridge, a six-year campaign that is the largest airborne survey ever made of ice at Earth's polar regions. view more (2009-10-09)
Has the mystery of the Antarctic ice sheet been solved?
A team of scientists from Cardiff University's School of Earth and Ocean Sciences and Amgueddfa Cymru - National Museum Wales travelled to Africa to find new evidence of climate change which helps explain some of the mystery surrounding the appearance of the Antarctic ice sheet. view more (2008-02-28)
Space shuttle Columbia's last flight formed clouds over Antarctica
A burst of mesospheric cloud activity over Antarctica in January 2003 was caused by the exhaust plume of the space shuttle Columbia during its final flight, reports a team of scientists who studied satellite and ground-based data from three different experiments. view more (2005-07-07)
NASA's AURA satellite peers into Earth's ozone hole
NASA researchers, using data from the agency's AURA satellite, determined the seasonal ozone hole that developed over Antarctica this year is smaller than in previous years. view more (2005-12-07)
Study shows snowfall hasn't increased over Antarctica in last 50 years
An international effort to determine the variability of recent snowfall over Antarctica shows that there has been no real increase in precipitation over the southernmost continent in the last half-century. view more (2006-08-11)
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)
NASA provides new perspectives on the earth's changing ice sheets
It's widely documented that climate change is causing the Greenland and Antarctic ice sheets to shrink. Air temperatures in many parts of the polar regions have increased and waters that surround parts of the ice sheets have warmed up. view more (2006-12-12)
Collapse of Antarctic Ice Shelf Unprecedented
The Antarctic Peninsula is undergoing greater warming than almost anywhere on Earth, a condition perhaps associated with human-induced greenhouse effects. view more (2005-08-04)
Alaska's Columbia Glacier continues on disintegration course
Alaska's rapidly disintegrating Columbia Glacier, which has shrunk in length by 9 miles since 1980, has reached the mid-point of its projected retreat, according to a new University of Colorado at Boulder study. view more (2005-12-08)
Study Finds Subglacial Water in West Antarctica Considerably More Active Than Previously Observed
The recent discovery of a subglacial water system beneath the West Antarctic ice sheet (WAIS) is causing scientists to rethink the mechanisms that control the flow of ice streams into the Ross Ice Shelf and ultimately into the Southern Ocean, according to a report in the February 15, 2007, issue of Science magazine online. view more (2007-02-16)
WHEELS WITHIN WHEELS: RARE ORBITAL ANOMALY MAY HAVE CAUSED GLOBAL COOLING 23 MILLION YEARS AGO
A rare coincidence of orbital cycles may have caused sudden global cooling 23 million years (Ma) ago, according to scientists, who used high resolution records and new techniques that allow astronomical calibration to be extended much further back in time. The late Oligocene to early Miocene Earth (20-26 Ma ago) experienced a complex climate... view more... (2001-06-21)
Emory Researcher Finds Crayfish Fossils Provide Missing Evolutionary Link
Crayfish body fossils and burrows discovered in Victoria, Australia, have provided the first physical evidence that crayfish existed on the continent as far back as the Mesozoic Era, says Emory University paleontologist Anthony Martin, who headed up a study on the finds. view more (2008-02-07)
Southern Ocean could slow global warming
The Southern Ocean may slow the rate of global warming by absorbing significantly more heat and carbon dioxide than previously thought, according to new research. view more (2006-12-06)
Alaskan storm cracks giant iceberg to pieces in faraway Antarctica
A severe storm that occurred in the Gulf of Alaska in October 2005 generated an ocean swell that six days later broke apart a giant iceberg floating near the coast of Antarctica, more than 8,300 miles away. view more (2006-10-03)
Climate Research: Oldest Ice in Process
Scientists at the Alfred Wegener Institute for Polar and Marine Research (AWI) are handling the oldest ice that has ever been unearthed: The ice cores, which were drilled during last winter in the Antarctic research station Dome C, are up to 900.000 years old. They come from a depth of 3200 metres and contain information about the climate and... view more... (2003-11-14)
Algae and pollen grains provide evidence of remarkably warm period in Antarctica's history
For Sophie Warny, LSU assistant professor of geology and geophysics and curator at the LSU Museum of Natural Science, years of patience in analyzing Antarctic samples with low fossil recovery finally led to a scientific breakthrough. view more (2009-10-01)
£37,000 Dream takes University of Warwick Researcher from the Boiling Heat of the Sun to the Cold of the Antarctic
A University of Warwick astrophysicist is to be extracted from her work studying extreme events involving the sun to join a scientific expedition to the extreme cold of the Antarctic. The NESTA "Dream Time Fellowship" award of £37,875 will let Professor Sandra Chapman, travel to the Southern ends of the earth to work with scientists based... view more... (2002-11-08)
Researchers plumb mysteries of Antarctic Mountains
The 3,000-kilometer-long Transantarctic Mountains are a dominant feature of the Antarctic continent, yet up to now scientists have been unable to adequately explain how they formed. view more (2007-07-20)
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)
Possible dinosaur burrows clues to survival strategies
Internationally renowned palaeontologist and Monash University Honorary Research Associate, Dr Anthony Martin has found evidence of a dinosaur burrow along the coast of Victoria, which helps to explain how dinosaurs protected themselves from climate extremes during the Cretaceous period - the final era for dinosaurs before their extinction. view more (2009-07-16)
