The MARSIS radar estimates the volume of water in the south pole of Mars
By studying the South Polar region of Mars, the MARSIS (Mars Advanced Radar for Subsurface and Ionospheric Sounding) radar of the Mars Express space probe has enabled the structure of the layered deposits of this region to be elucidated. view more (2007-04-02)
Science From Space
Scientists working at the Bristol Glaciology Centre at the University of Bristol will be staying up all night to watch the lift-off of the largest and most powerful Earth observation satellite ever to be launched by the European Space Agency. The satellite, called ENVISAT, is 25 metres high, ten metres wide and weighs over eight tons. Fully... view more... (2002-02-28)
Measuring water from space
Observations from satellites now allow scientists to monitor changes to water levels in the sea, in rivers and lakes, in ice sheets and even under the ground. As the climate changes, this information will be crucial for monitoring its effects and predicting future impacts in different regions. view more (2008-11-13)
Wilkins Ice Shelf hanging by its last thread
The Wilkins Ice Shelf is experiencing further disintegration that is threatening the collapse of the ice bridge connecting the shelf to Charcot Island. Since the connection to the island in the image centre helps to stabilise the ice shelf, it is likely the break-up of the bridge will put the remainder of the ice shelf at risk. view more (2008-07-11)
Study casts doubt on 'Snowball Earth' theory
"Snowball Earth" proponents, who say that Earth's oceans were covered by thick ice, explain the survival of life by hypothesizing the existence of small warm spots, or refugia. view more (2005-09-30)
Research icebreaker 'Polarstern' drifting in Antarctic ice
Since November 27, an ice floe has served as home as well as working place for 55 scientists from 11 nations. The research icebreaker 'Polarstern' of the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven has been tied up firmly to a drifting ice floe in the Antarctic Weddel Sea. view more (2004-12-09)
First direct evidence that human activity is linked to Antarctic Ice Shelf collapse
The first direct evidence linking human activity to the collapse of Antarctic ice shelves is published this week in the Journal of Climate. view more (2006-10-17)
Older Arctic sea ice replaced by young, thin ice, says CU-Boulder study
A new study by University of Colorado at Boulder researchers indicates older, multi-year sea ice in the Arctic is giving way to younger, thinner ice, making it more susceptible to record summer sea-ice lows like the one that occurred in 2007. view more (2008-01-14)
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)
How chilly was the last ice age?
Polar oceans permanently covered with ice, temperatures ten to twelve degrees Celsius lower than today in the North Atlantic region, tropical oceans on the other hand only two degrees Celsius below modern values: Until quite recently these were the general ideas climate researchers had about the climax of the last ice age 20.000 years ago. Now... view more... (1999-05-03)
New Arctic satellite data shows Arctic literally on thin ice
The latest data from NASA and the University of Colorado at Boulder's National Snow and Ice Data Center show the continuation of a decade-long trend of shrinking sea ice extent in the Arctic, including new evidence for thinning ice as well. view more (2009-04-07)
Arctic sea ice recovers slightly in 2009, remains on downward trend, says U. of Colorado report
Despite a slight recovery in summer Arctic sea ice in 2009 from record-setting low years in 2007 and 2008, the sea ice extent remains significantly below previous years and remains on a trend leading toward ice-free Arctic summers, according to the University of Colorado at Boulder's National Snow and Ice Data Center. view more (2009-10-07)
Scientists discover pentagonal ice
Scientists at the University of Liverpool have discovered a five-sided ice chain structure that could be used to modify future weather patterns. view more (2009-04-07)
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)
Role of Silica in Climate Cycles
New research from the University of East Anglia (UEA) has demonstrated that the compound silica was not solely responsible for changes in carbon dioxide levels during past Ice Ages. It is already known from scientific research that during past Ice Ages increased amounts of silica, a common component of wind-blown dust, were deposited in the ocean.... view more... (2001-06-21)
Sea level on the rise - in real and virtual worlds
The climate system, and in particular sea level, may be responding more quickly to rising carbon emissions than climate scientists have estimated with climate models. view more (2007-02-05)
Cooling with tiny crystals
Refrigeration equipment prevents sweaty brows in the summer and also keeps our food fresh for longer periods. With CryoSol®, a new and easily pumpable liquid ice suspension, space requirements for cold storage are much lower than with conventional coolants. view more (2004-08-27)
Higher Water Temperatures and Reduced Ice Cover In the Arctic Ocean
Over the past six weeks, scientists aboard the research vessel "Polarstern" of the Alfred Wegener Institute for Polar and Marine Research have been investigating changes in ocean temperature and sea ice cover in the area of Fram Strait between Spitsbergen and Greenland. In this area significant exchange of water masses between the Arctic Ocean... view more... (2004-08-27)
Cosmic Rays Hit Space Age High
Planning a trip to Mars? Take plenty of shielding. According to sensors on NASA's ACE (Advanced Composition Explorer) spacecraft, galactic cosmic rays have just hit a Space Age high. view more (2009-09-30)
U.S.-Led, International AGAP Team Poised to Probe One of Antarctica's Last Unexplored Places
A U.S.-led, multinational team of scientists from six nations will pierce the mysteries of one of the globe's last major unexplored places this month. Using sophisticated airborne radar and other Information Age tools and techniques, the scientists will virtually "peel away" more than four kilometers (2.5 miles) of ice covering an... view more...
