Latest Polar ice cap Stories
WASHINGTON, April 6 /PRNewswire-USNewswire/ -- The latest Arctic sea ice data from NASA and the National Snow and Ice Data Center show that the decade-long trend of shrinking sea ice cover is continuing.
NASA and the National Snow and Ice Data Center say that the decade-long trend of shrinking sea ice cover in the Arctic is continuing and new evidence suggests that the ice cap is thinning as well.
ESAâ€™s Mars Express orbiter imaged the snow-laden region of Rupes Tenuis on the martian north pole on July 29, 2008.
Renowned Arctic explorer Pen Hadow and two companions have set out on a grueling 90-day trek to the North Pole, collecting data along the way to determine precisely how fast the Arctic sea-ice is melting.
Following a record-breaking season of arctic sea ice decline in 2007, NASA scientists have kept a close watch on the 2008 melt season. Although the melt season did not break the record for ice loss, NASA data are showing that for a four-week period in August 2008, sea ice melted faster during that period than ever before.
Environmental scientists studying the world's shrinking polar ice sheets will soon get a substantial boost in computing power thanks to IU's Polar Grid Project.
Scientists are now able to better explain why Marsâ€™s residual southern ice cap is misplaced, thanks to data from ESAâ€™s Mars Express spacecraft - the martian weather system is to blame. And so is the largest impact crater on Mars â€“ even though it is nowhere near the south pole.
US scientists say global warming caused arctic sea ice to melt to its second-lowest level this year, rising slightly from 2007's record but still showing a downward trend.
Scientists at the National Snow and Ice Data Center say Arctic Ocean sea ice has melted to the second lowest minimum since satellite observations began.
New observations from NASA's Mars Reconnaissance Orbiter indicate that the crust and upper mantle of Mars are stiffer and colder than previously thought.
