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...

Winter Ice Is On The Decline Across Alaskan Lakes
2014-02-03 10:22:48

Brett Smith for redOrbit.com - Your Universe Online According to a new study from the European Space Agency, ice in northern Alaska’s lakes during winter months is on the decline. Twenty years of satellite radar images in the study, which was published in The Cryosphere, show how shifts in our climate are affecting high-latitude regions. [ Watch the video: Monitoring Lake Ice ] Alterations in air temperature and winter precipitation over the last 50 years have affected the timing,...

Pine Island Glacier Retreating
2014-01-14 14:44:51

Lee Rannals for redOrbit.com - Your Universe Online Antarctica’s Pine Island Glacier (PIG) is now in an irreversible retreat, according to a study published in the journal Nature Climate Change. PIG is one of the biggest single contributors to global sea-level rise, and the latest study says that it could add as much as 0.39-inches to ocean levels in 20 years. “Over the past 40 years Pine Island Glacier in West Antarctica has thinned at an accelerating rate, so that at present it is...

Arctic Ice Improving
2013-12-16 15:27:28

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency’s (ESA) CryoSat satellite has delivered some good news about the Arctic sea ice this fall. New measurements taken by CryoSat show the volume of Arctic sea ice has significantly increased this fall, rising by about 50 percent compared to last year. Satellites have been showing a downward trend in the area of Arctic Ocean covered by ice over the past few decades, so the latest measurements are much welcomed news....

ESA CryoSat Mission Confirms Antarctic Ice Loss Is On The Rise
2013-12-12 06:08:21

Alan McStravick for redOrbit.com - Your Universe Online With news out of San Francisco this week, at the autumn meeting of the American Geophysical Union (AGU), we learned scientists have incorrectly estimated the amount of ice being lost on the polar continent of Antarctica. This environmental faux pas directly affects the estimates on global sea level rise as well. The team presenting these findings conducted their research with the Natural Environment Research Council’s Center for...
