redOrbit Staff & Wire Reports - Your Universe Online Previous instances of rapid thinning of Pine Island Glacier suggests that current ice loss in the Antarctic could continue for several more decades, a team of geologists from the US, UK and Germany report in this week’s edition of the journal Science. Pine Island Glacier, which is part of the West Antarctic Ice Sheet, is rapidly accelerating, thinning and retreating, and the researchers report that it has thinned rapidly in the...

Disappearing Snow Increases Risk Of Ice Shelves Collapsing  In Antarctica
2014-01-30 08:19:42

British Antarctic Survey Sea-level research in Antarctica A number of floating ice shelves in Antarctica are at risk of disappearing entirely in the next 200 years, as global warming reduces their snow cover. Their collapse would enhance the discharge of ice into the oceans and increase the rate at which sea-level rises. A rapid reduction of greenhouse gas emissions could save a number of these ice shelves, researchers at Utrecht University and the British Antarctic Survey say in a new...

Sea Anemones In Antarctica Find A Home On The Ice
2014-01-17 07:46:08

April Flowers for redOrbit.com - Your Universe Online A team of scientists and engineers with the Antarctic Geological Drilling (ANDRILL) Program used a camera-equipped robot to explore beneath the Ross Ice Shelf off Antarctica, making an astonishing discovery. The team found many thousands of small sea anemones that were burrowed into the underside of the ice shelf with their tentacles protruding into frigid water like flowers on a ceiling. "The pictures blew my mind," said...

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...

Shrinking Habitat Doesn't Keep Emperor Penguins From Breeding
2014-01-09 11:35:03

[ Watch the Video: Emperor Penguins Are Breeding On Ice Shelves ] Gerard LeBlond for redorbit.com - Your Universe Online The emperor penguins of Antarctica, which have lost much of their breeding habitat due to shrinking ice pack, have shown their resiliency to environmental impacts by moving to new breeding locations where ice is thicker, as has been seen via satellite images, reports BBC News' Jonathan Amos. A new study, published in the online journal PLOS ONE, describes the...

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...

The Health Of Antarctic Glaciers Relies On Salt Intake: NASA
2013-12-06 10:19:26

April Flowers for redOrbit.com - Your Universe Online An intriguing link between sea ice conditions and the melting rate of Totten Glacier, the glacier in East Antarctica that discharges the most ice into the ocean, has been found by a NASA-led study. The discovery, published in Nature Communications, involves cold, extra salty water—brine—that forms within openings in sea ice. The findings will add to our understanding of how ice sheets interact with the ocean, and may improve our...

Channels In Antarctic Ice Shelf Will Help Predict Future Of Antarctic Ice
2013-10-07 04:31:47

redOrbit Staff & Wire Reports - Your Universe Online The discovery of hundreds of kilometers worth of channels beneath a floating ice shelf in Antarctica could help experts understand how the ice will respond to changes in environmental conditions, according to a study published Sunday in the journal Nature Geoscience. Researchers from the University of Exeter, Newcastle University, the University of Bristol, the University of Edinburgh, the British Antarctic Survey and the...

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...
