Heavy sea ice conditions have thwarted a science mission from reaching the Larsen C Ice Shelf in Antarctica from which a large iceberg broke off in July ... of the seafloor biodiversity in this area and provide a more accurate timeframe for retreat of ice sheets from the eastern side of the Antarctic Peninsula.
Extreme cold in Britain, Switzerland and Japan, a record-breaking cold snap in Canada and the US and an expansion of the East Antarctic ice sheet coincided with a Bureau of Meteorology tweet (later retracted) that January 7 had set a heat record for the Sydney Basin. Steffen told us these seemingly ...

But "the elephant in the room" is the polar ice sheets, said Naish. "For Antarctica," he said, showing another PowerPoint slide, "it's very much in that red area of west Antarctica where we're seeing significant contributions; in fact, east Antarctica, if anything east Antarctica ice sheets are gaining a bit of mass.".
The researchers found that between 2008 and 2015, the East Antarctic Ice Sheet had essentially no change in its rate of ice discharge—ice flow into the ocean. They also confirmed that the flow of West Antarctica's Thwaites and Pine Island glaciers into the ocean continues to accelerate, albeit at a slower ...
And they have suspected this could lead to more snowfall in Antarctica, but observations were few and far apart. So Brooke Medley, a NASA research scientist, and her colleagues, analyzed a 500-foot-deep ice core extracted from the thick ice sheet in Queen Maud Land, an area in East Antarctica due ...
The findings, published February 13 in The Cryosphere, reveal accelerating ice flow in the West Antarctic ice sheet, and a steady flow in the East. Much of the findings confirm what previous studies have shown, but using more direct and precise measurements of the ice sheets. Based on seven years of ...

A NASA study has provided the clearest picture yet of changes in Antarctic ice flow into the ocean. The findings uses satellite data to confirm accelerating ice losses from the West Antarctic Ice Sheet and also reveal surprisingly steady rates of flow from its much larger neighbor to the east.

Steven Phipps, a paleo ice sheet modeller from the University of Tasmania, knows all about the challenges of understanding the great southern continent. "There is so much uncertainty because we know so little about the Antarctic ice sheet," Dr Phipps said. "Antarctica is very remote. It is a very extreme ...
Before the ice ages began, back in the Pliocene epoch, say four million years ago, the East Antarctic ice sheet was the only such mass of ice on Earth. The Arctic was anywhere from ten to twenty degrees warmer than it is today and probably entirely free of ice, and the world was, on average, an estimated ...
The melting of Greenland or the East Antarctic Ice Sheet could not explain it, because both are located on solid earth and would respond relatively slowly to warming. By contrast, much of the West Antarctic Ice Sheet is grounded well below sea level. That makes it a “uniquely vulnerable and unstable body ...
Ice sheets play a crucial role in maintaining sea levels. The amount of ice loss from the West Antarctic Ice Sheet has accelerated, increasing by 70% in the past decade, according to research published in the journal Science. While the ice sheet in East Antarctica is gaining in mass because of increased ...

A team from the National Centre for Antarctic and Ocean Research (NCAOR), Goa, and the Norwegian Polar Institute drilled through an ice shelf up to a depth ... Maitri in Dronning Maud Land in eastern Antarctica as part of a four-year Madice project to study Antarctica's contribution to global sea level rise.

It is a piece of a larger puzzle that begins with an ice rise in East Antarctica. Vikram Goel, 28, says he is not answering any big questions yet but is hopeful that what he has researched will be a step towards a larger understanding of how ice sheets in the region will behave with change in climate. Goel is a ...
“Researchers have generally thought that the East Antarctic Ice sheet has remained relatively stable despite global warming. But this is not the case, according to a recent study published in Science Advances. Chad Greene and a team of researchers discovered that the Totten, the largest glacier in East ...
Enough water is frozen into the East Antarctic ice sheet that if all of it melted, it could raise sea levels nearly 174 feet. The ice sheet was previously believed to be much more stable, especially in comparison with its cousins: the West Antarctic and Greenland ice sheets. But a study published last Wednesday ...
New research has confirmed one of the worst nightmares of climate science: the instability of the East Antarctic ice sheet. This vast mass holds enough water to raise sea levels by 53 metres worldwide. And researchers have confirmed that one stretch of the southern polar coastline has melted many times in ...
Washington, Dec 18 The East Antarctic Ice Sheet, which locks away enough water to raise sea level by an estimated 53 metres - more than any other ice sheet on the planet - may not be as stable as thought, scientists say. A study, published in the journal Nature, found that the ice sheet has a long history of ...
"It turns out that for much of the East Antarctic Ice Sheet's history, it was not, as commonly perceived, a large, stable ice sheet that underwent only minor changes in size over millions of years," he said. "Rather, we have evidence for a very dynamic ice sheet that grew and shrank significantly between glacial ...
The East Antarctic Ice Sheet locks away enough water to raise sea level an estimated 53 meters (174 feet), more than any other ice sheet on the planet. It's also thought to be among the most stable, not gaining or losing mass even as ice sheets in West Antarctica and Greenland shrink. But new research ...
Scientists sounding the seabed off Antarctica have uncovered some surprising episodes from the continent's history: The East Antarctic Ice Sheet, they say, experienced a series of dramatic retreats in the distant past—retreats that were often punctuated by catastrophic floods of meltwater that erupted from ...
The Greenland Ice Sheet extends about 656,000 square miles (1.7 million square km), covering most of the island of Greenland, or three times the area of Texas, according to the National Snow & Ice Data Center. The Antarctic Ice Sheet covers nearly 5.4 million square miles (14 million square km). Both ice ...
