Latest Polar ice cap Stories
Even in the clearest, bluest sky on Earth, there is still water vapor in our atmosphere. If you could condense all the water vapor out of the atmosphere above you, it would form a layer of water two centimeters deep. On Mars today, there is also water vapor in the atmosphere but it would create a layer just 10 micrometers thick.
SAN FRANCISCO—NASA scientists have discov
Melting Arctic sea ice has shrunk to a 29-year low, significantly below the minimum set in 2005, according to preliminary figures from the National Snow and Ice Data Center, part of the University of Colorado at Boulder.
A team of NASA and university scientists has found clear evidence that extensive areas of snow melted in west Antarctica in January 2005 in response to warm temperatures.
It is perhaps an unlikely combination â€“ an international team of scientists stationed in Svalbard, Norway and two polar explorers crossing the North Pole on foot. Both teams, however, are currently part of a common effort to collect vital data on the ground and from the air in support of ESA's ice mission CryoSat-2.
Vast, yet remote; frigid, yet teeming with life; stark and barren, yet serenely beautiful -- these are just a few of the contradictions of Earth's polar regions.
The amount of water trapped in frozen layers over Mars' south polar region is equivalent to a liquid layer about 11 metres deep covering the planet.
What we learn about the poles can teach us about the history of the entire planet. All Mars science is polar science.
Every spring brings violent eruptions to the south polar ice cap of Mars, according to researchers interpreting new observations by NASA's Mars Odyssey orbiter.
New high-resolution images of mid-latitude Mars are revealing glacier-formed landscapes far from the Martian poles, says a leading Mars researcher.
