Researchers Decipher Climate Paradox From The Miocene

AWI Scientists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), have deciphered a supposed climate paradox from the Miocene era by means of complex model simulations. When the Antarctic ice sheet grew to...

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...

Antarctica Holds Subglacial Valley Bigger Than The Grand Canyon

[ Watch the Video: A Giant Is Lurking Beneath Antarctica's Ice ] Gerard LeBlond for redOrbit.com - Your Universe Online A team of scientists from Newcastle University, the University of Bristol’s Glaciology Centre, the British Antarctic Survey and the universities of Edinburgh, Exeter and York, have discovered a giant trench below the ice in Antarctica. The research team has spent the last three seasons in the West Antarctic region investigating and mapping the area. Recently, they...

Climatic Variability Has A Significant Impact On Pine Island Glacier
2014-01-03 07:31:08

redOrbit Staff & Wire Reports - Your Universe Online Pine Island Glacier, one of the largest routes for ice to flow from Antarctica into the sea, is far more susceptible to climatic and ocean variability than previously believed, according to research published Thursday in the advanced online version of the journal Science. Observations from Dr. Pierre Dutrieux of the British Antarctic Survey (BAS) and his colleagues showed sizable fluctuations in ocean heat in Pine Island Bay. They...

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...

Greenland Ice Sheet Is Hiding Subglacial Lakes
2013-11-28 04:29:14

redOrbit Staff & Wire Reports - Your Universe Online Researchers have discovered a pair of subglacial lakes discovered over 800 meters beneath the Greenland Ice Sheet – the first ever to be discovered in the island nation, according to research appearing in the latest edition of the journal Geophysical Research Letters. The two lakes are reportedly between eight and 10 square kilometers in surface area, but might have been up to three times larger than their current size at one...

Antarctic Glacier Rapidly Melting
2013-09-19 12:50:41

Michael Harper for redOrbit.com - Your Universe Online When it comes to predicting the effects of global warming on our environment, scientists look to the world’s glaciers, exceptionally large masses of ice which are melting into the sea. Now researchers from the University of Alaska Fairbanks say they've completed a thorough examination of these melting glaciers to get a better picture of how climate change is affecting Earth. Specifically, the researchers examined the ice melt from...

New research has revealed that more ice leaves Antarctica by melting from the underside of submerged ice shelves than was previously thought, accounting for as much as 90 per cent of ice loss in some areas. Iceberg production and melting causes 2,800 cubic kilometers of ice to leave the Antarctic ice sheet every year. Most of this is replaced by snowfall but any imbalance contributes to a change in global sea level. For many decades, experts have believed that the most important process...

Pine Island Glacier Is Melting From Below
2013-09-13 04:27:05

[ Watch the Video: Warm Ocean Melting Pine Island Glacier ] redOrbit Staff & Wire Reports - Your Universe Online The floating ice shelf in a remote region of Antarctica is being melted by warm ocean water, not hot air, an international team of researchers report in the latest edition of the journal Science. As described in the new study, an expedition to Pine Island Glacier allowed scientists to get an up-close-and-personal look beneath the ice of one of the most difficult to...

British Antarctic Survey To Launch Long-Term Survey Of Pine Island Glacier
2013-09-09 10:34:32

Lawrence LeBlond for redOrbit.com - Your Universe Online An ambitious science mission is about to begin in Antarctica, with team members from the British Antarctic Survey (BAS) looking to understand why the continent’s Pine Island Glacier (PIG), located on the West Antarctic Ice Sheet, is rapidly diminishing. The goal of the mission is to ultimately discern if rapid ice loss will continue to increase or if it will slow down. The team argues that this research is crucial for...

Antarctica
2013-02-18 10:15:24

Antarctica is the Earths southernmost continent; it contains the geographic South Pole. It’s situated in the Antarctic area of the Southern Hemisphere, almost completely south of the Antarctic Circle, and is bordered by the Southern Ocean. It’s the fifth-largest continent at 5.4 million sq miles. On average, it is the driest, coldest, and windiest continent as well as having the highest average elevation of all the continents. Considered a desert, the annual precipitation is only 8...
