European lead in reading past climates from ice cores
Climate change is a reality today, but how can we find out about the future dangers it poses" What we really need is a full record of the Earth's climate for several hundred thousand years, complete with samples of air from different epochs that can be taken to the lab for analysis. view more (2007-10-12)
NASA researchers find snowmelt in Antarctica creeping inland
On the world's coldest continent of Antarctica, the landscape is so vast and varied that only satellites can fully capture the extent of changes in the snow melting across its valleys, mountains, glaciers and ice shelves. view more (2007-09-21)
Icy calculations on a hot topic
University of Utah mathematicians have arrived at a new understanding of how salt-saturated ocean water flows through sea ice - a discovery that promises to improve forecasts of how global warming will affect polar icepacks. view more (2007-09-11)
ODP scientists say no large Northern Hemisphere ice sheets 41 million years ago
New research to test global ice volume approximately 41.6 million years ago shows that ice caps at this time, if they existed at all, would have been small and easily accommodated on Antarctica. view more (2007-08-23)
Texas researchers and educators head for Antarctica
It's been more than 100 years since anyone has journeyed to this section of Antarctica's Amundsen Sea, but that is about to change. view more (2007-08-16)
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)
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)
March of the giant penguins
Giant prehistoric penguins? In Peru? It sounds more like something out of Hollywood than science, but a researcher from North Carolina State University along with U.S., Peruvian and Argentine collaborators has shown that two heretofore undiscovered penguin species reached equatorial regions tens of millions of years earlier than expected and... view more...

Hundreds of Antarctic Peninsula glaciers accelerating as climate warms
Hundreds of glaciers on the Antarctic Peninsula are flowing faster, further adding to sea level rise according to new research published this week in the Journal of Geophysical Research. Climate warming, that is already causing Antarctic Peninsula increased summer snow melt and ice shelf retreat, is the most likely cause. view more (2007-06-06)
Study of underground lakes in Antarctica could be critical, prof says
The discovery of interconnected lakes beneath kilometers of ice in Antarctica could be one of the most important scientific finds in recent years, but proper procedures need to be established before investigation begins, says a Texas A&M University scientist who is a leader in the research efforts. view more (2007-06-06)
B12 Is Also an Essential Vitamin for Marine Life
B12 - an essential vitamin for land-dwelling animals, including humans - also turns out to be an essential ingredient for growing marine plants that are critical to the ocean food web and Earth's climate, scientists have found. view more (2007-05-21)
Short-circuit found in ocean circulation
Scientists have discovered how ocean circulation is working in the current that flows around Antarctica by tracing the path of helium from underwater volcanoes. The details are published in Nature this week. view more (2007-05-11)
Global warming, Antarctic ice is focus of multinational workshop
As the national repository for geological material from the Southern Ocean, the Antarctic Marine Geology Research Facility at Florida State University houses the premier collection of Antarctic sediment cores -- and a hot new acquisition will offer an international team of scientists meeting there May 1-4 its best look yet at the impact of global... view more...

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)
NASA and USGS Produce Most Detailed Satellite Views of Antarctica
Researchers from NASA and the U.S. Geological Survey (USGS), Golden, Colo., have woven together more than a thousand images from the Landsat 7 satellite to create the most detailed, high-resolution map ever produced of Antarctica. The Landsat Image Mosaic of Antarctica (LIMA) offers views of the coldest continent on Earth in 10 times greater... view more... (2007-03-08)
Antarctic Ice Sheet's Hidden Lakes Speed Ice Flow Into Ocean, May Disrupt Climate
Just as explorers once searched the vast reaches of Africa's Nile River for clues to its behavior and ultimate source, modern-day scientists are searching Antarctica for its hidden lakes and waterways that can barely be detected at the surface of the ice sheet. view more (2007-03-07)
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)
Delft nano-detector very promising for remote cosmic realms
A miniscule but super-sensitive sensor can help solve the mysteries of outer space. Cosmic radiation, which contains the terahertz frequencies that the sensors detect, offers astronomers important new information about the birth of star systems and planets. view more (2007-01-18)
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)
Volcanic blast likely killed and preserved juvenile fossil plesiosaur found in Antarctica
Amid 70-mile-an-hour winds and freezing Antarctic conditions, an American-Argentine research team has recovered the well-preserved fossil skeleton of a juvenile plesiosaur-a marine reptile that swam the waters of the Southern Ocean roughly 70 million years ago. view more (2006-12-12)
