Brett Smith for redOrbit.com - Your Universe Online An international team of researchers has developed a new, vivid map illustrating the world’s seafloor with twice the detail and accuracy of the previous version, which was created over 20 years ago. Using two streams of previously untapped data, scientists have mapped thousands of previously uncharted mountains rising from the seafloor along with providing additional clues about the formation of the continents. According to a study...

European Space Agency Although not designed to map changes in Earth’s gravity over time, ESA’s extraordinary satellite has shown that the ice lost from West Antarctica over the last few years has left its signature. More than doubling its planned life in orbit, GOCE spent four years measuring Earth’s gravity in unprecedented detail. Scientists are now armed with the most accurate gravity model ever produced. This is leading to a much better understanding of many facets of our...

Chuck Bednar for redOrbit.com - Your Universe Online The sea level around the coast of Antarctica is expected to rise faster than the projected global rate, experts from the University of Southampton report in research appearing Sunday in the advanced online edition of the journal Nature Geoscience. In the paper, lead author Craig Rye and colleagues from the National Oceanography Centre, the British Antarctic Survey and the Scottish Association for Marine Science explain that satellite...

digital elevation models for Greenland and Antarctica

April Flowers for redOrbit.com - Your Universe Online Data from the European Space Agency's (ESA) CryoSat-2 spacecraft has been used to map elevation and elevation changes in both Greenland and Antarctica by a team of researchers from the Alfred Wegener Institute (AWI) in Germany. The new maps, which are the most complete to ever be created from a single satellite mission, reveal the ice sheets are losing volume at an unprecedented yearly rate (approximately 500 cubic kilometers). The...

CryoSat Shows Increase In Antarctica’s Ice Losses
2014-05-19 03:52:32

ESA Three years of observations from ESA’s CryoSat satellite show that the Antarctic ice sheet is now losing 159 billion tonnes of ice each year – twice as much as when it was last surveyed. The polar ice sheets are a major contributor to the rise in global sea levels, and these newly measured losses from Antarctica alone are enough to raise global sea levels by 0.45 mm each year. These latest findings by a team of scientists from the UK’s Centre for Polar Observation and...

Ice Mission And Harsh Polar Camping
2014-05-16 03:57:04

ESA While camping may appeal to some, scientists recently took the pastime to punishing limits. Enduring the bitter Arctic cold out on the sea ice, they were part of a major international effort to ensure ESA’s CryoSat satellite is delivering a true picture of Earth’s changing ice. Considered a barometer of climate change, diminishing polar ice has been a hot topic for a number of years. Over the last few decades, satellites have shown a downward trend in the area of Arctic Ocean...

redOrbit Staff & Wire Reports - Your Universe Online Scientists working on NASA’s Operation IceBridge mission are en route to Greenland to kick off this year’s Arctic land and sea ice data collection efforts, officials from the US space agency announced on Wednesday. On Monday, the researchers departed from the Wallops Flight Facility in Wallops Island, Virginia on board the agency’s P-3 research aircraft. They will be collecting and reporting valuable information on rapidly...

WASHINGTON, March 12, 2014 /PRNewswire-USNewswire/ -- Researchers aboard NASA's P-3 research aircraft left the agency's Wallops Flight Facility in Wallops Island, Va., March 10 for Greenland to begin a new season of collecting data on Arctic land and sea ice. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The mission, known as Operation IceBridge, is to gather data on changes to polar ice and maintain continuity of measurements between NASA's Ice, Cloud and Land Elevation...

Acquiring Signals From A Speeding Satellite
2014-03-07 14:51:31

ESA Soaring high above Earth as they speed through space, satellites are difficult targets to track. Now a new approach developed in Europe is helping ground stations to acquire signals faster and more accurately than ever before. During launch, a satellite is flung into orbit with tremendous force, attaining speeds of over 28 000 km/h – about 40 times faster than a commercial airliner. A critical moment is when the satellite separates from its rocket and starts transmitting radio...

NASA IceBridge Science Team Making Plans For The Future
2014-02-13 14:51:44

George Hale - NASA Twice a year, members of NASA's Operation IceBridge science team meet to discuss the mission's goals and progress, to define plans for upcoming field campaigns and get feedback from the scientific community. The science team met from January 28 through 30, 2014, at NASA's Goddard Space Flight Center in Greenbelt, Md. This was the first meeting for IceBridge's new science team, which will serve from 2014 until 2017. IceBridge's previous science team was selected in...


Word of the Day
ween
  • To think; to imagine; to fancy.
  • To be of opinion; have the notion; think; imagine; suppose.
The word 'ween' comes from Middle English wene, from Old English wēn, wēna ("hope, weening, expectation"), from Proto-Germanic *wēniz, *wēnōn (“hope, expectation”), from Proto-Indo-European *wen- (“to strive, love, want, reach, win”).
