glaciers in the Antarctic

Antarctica - The ice deep below eight of Antarctica's largest glaciers is melting at an alarming rate, a new scientific analysis has revealed. ... then many models show that a significant portion of the Antarctic ice sheets will eventually melt, especially Western Antarctica," Burton said, adding that even if it took ...

An ambitious mapping project demonstrates that glaciers all around the Antarctic coastline, and particularly in West Antarctica, are retreating inland (Climatewire, April 4). Scientists already generally agree that glacier retreat in Antarctica is largely being driven by warm water seeping underneath the ...

They spent the Antarctic summer, which is Maine's winter, taking samples, transporting hundreds of tons of gear, or sticking cameras on the backs of seals. In doing so, they hope to uncover the secrets of Antarctica's glaciers, fossils, and living mammals; what they find might teach us more about our world ...

The ice sheet is not one homogeneous mass, but a collection of glaciers all moving slowly but inexorably towards the sea. Their retreat is happening underwater, and invisibly, as the ocean erodes the foot of the glacier, known as the “ground line”, where its contact with the sea floor ends. Beyond that point ...

Although meteorites frequently fall all over the world, they get concentrated in special places in Antarctica, making them easier to find. As meteorites strike glaciers, they get buried in the ice and accumulate over thousands of years. As the glaciers slowly flow, the meteorites are carried with them. If a glacier ...

Retreat at Thwaites Glacier, on the other hand—another of West Antarctica's monster glaciers, and currently the subject of greatest concern among Antarctic ice experts—has slightly increased in the last few years, from about 1,100 feet to nearly 1,400 feet per year. The news comes as U.S. and U.K. ...

Antarctica isn't what it used to be. The ice that covers the continent and its surrounding ocean waters is always in flux with the seasons: Ice melts in the summer, and winter snowfall eventually gets packed down into new ice to replace what was lost. But in recent years, that snowfall hasn't been able to make ...

More of one of Antarctica's largest and most important glaciers is floating on top of the ocean than previously thought, researchers say, which could have a significant impact on the rise of global sea levels. The new research from the Australian Antarctic Program has found the Totten Glacier, located in the ...

Airborne soot produced by wildfires and fossil-fuel combustion and transported to the remote McMurdo Dry Valleys of Antarctica contains levels of black carbon too low to contribute significantly to the melting of local glaciers, according to a new study by researchers supported by the National Science ...

Presently, glaciers occupy about 10 per cent of the world's total land area, with most located in polar regions like Antarctica, Greenland, and the Canadian Arctic. Glaciers can be thought of as remnants from the last Ice Age, when ice covered nearly 32 percent of the land, and 30 percent of the oceans.

One idea is to build mounds of sand and stone underwater at the mouth of at-risk glaciers near the sea, such as Thwaites Glacier in the Antarctic. The walls, which would stretch for miles on the seafloor, would slow or reverse their collapse. Robinson Meyer reported on this proposal for The Atlantic in ...

(right) The change in surface ice velocity from 2008 to 2015 in meters per year for that region, whose boundary is identified in both panels by ...

A fascinating video of ice being dropped 90 metres into an Antarctic glacier has been shared thousands of times on Twitter – and it's sure to appeal to your ... Those holes are from Taylor Glacier in the McMurdo Dry Valleys of Antarctica, where Peter and his team were drilling to recover ice cores and study ...

Sea ice mixed with glacier ice off the coast of Brabant Island, Palmer Archipelago, Antarctic. (Christian ... Sydney – Sea ice cover in Antarctica has dropped to its second-lowest on record, Australian authorities said on Friday, adding that it was not yet clear what was driving the reduction after several years of ...

It's not shocking that dropping a chunk of ice down a 90-meter borehole into an Antarctic glacier sounds cool, but the actual sound it makes is still totally unexpected. In this video posted ... When #science is done, it's fun to drop ice down a 90 m deep borehole in an #Antarctic #glacier ❄ . So satisfying ...

A decade ago, a thick layer of ice covered the Collins Glacier on Antarctica's King George Island. Now, the ... But even as these melting glaciers worry the scientific world, the presence in Antarctica of plants proving resistant to extreme conditions has also sparked hope for a warming planet. Chile is one of ...

A decade ago, a thick layer of ice covered the Collins Glacier on Antarctica's King George Island. ... over a 15-year period, and even within a human's lifetime, you can already see the changes brought about by climate change,” the director of the Chilean Antarctic Institute (INACH), Marcelo Leppe, told AFP.

Antarctica's glaciers are on the run: Landsat reveals accelerating melt. ANTARCTICA is melting. Fast. New satellite data has been compiled into a map revealing ... The flow of Antarctic ice, derived from feature tracking of Landsat imagery. Picture: NASA Earth ObservatorySource:Supplied. That's up 36 ...

The new software was used to parse through hundreds of thousands of satellite images of Antarctic glacier movement from 2013 to 2015 and, afterward, compared that data to older measurements to reveal the changes outlined in the map. It allowed the researchers to investigate ice flow in parts of the ...

Findings published in the journal Cryosphere reveal they are slipping ever faster into the Southern Ocean. There, as icebergs, they melt away. Calculations based on seven years of Landsat satellite images reveal 1,929 gigatons of ice broke away in 2015. The flow of Antarctic ice, derived from feature ...

Scientists from the British Antarctic Survey are taking off this Wednesday to explore a once-inaccessible marine ecosystem beneath the Larsen C ice ... The ice shelf, which is essentially like a massive ice cube buttressing glaciers from sliding into the sea, is the fourth largest in the world, according to NASA.

But the concept of polar geoengineering — physically manipulating conditions in the Arctic and Antarctic to try to protect the ice, if only temporarily — has been ... that the intervention could potentially be applied to one of the world's largest and most vulnerable glaciers, Thwaites Glacier in West Antarctica.

The researchers found that a previously unmeasured acceleration of glacier flow into Antarctica's Getz Ice Shelf on the southwestern part of the continent is likely a result of ice-shelf thinning. The glaciers feeding Marguerite Bay on the western Antarctic Peninsula, increased their rate of flow by 1,300 to ...
