AWI researchers recently assessed subglacial lakes detected by satellite, and found very little water. But if that's the case, what is the source of the East Antarctic Ice Sheet's massive ice streams?
Large rock hills deep below glaciers can cause huge channels on the ice surface – even if the hills are buried under two kilometres of ice.
Winds blowing across snow dunes on Antarctica's Ross Ice Shelf cause the massive ice slab's surface to vibrate, producing a near-constant set of seismic "tones" scientists could potentially use to monitor changes in the ice ...
More than 26,000 years ago, sea level was much lower than it is today partly because the ice sheets that jut out from the continent of Antarctica were enormous and covered by grounded ice—ice that was fully attached to ...
As global warming outpaces efforts to tame it, scientists have proposed building massive underwater structures to prevent an Antarctic glacier the size of Britain from sliding into the sea and lifting the world's oceans by ...
Targeted engineering projects to hold off glacier melting could slow down the collapse of ice sheets and limit sea-level rise, according to a new study published in the European Geosciences Union journal The Cryosphere. While ...
In July 2017, one of the largest icebergs on record calved from the Larsen C ice shelf in Antarctica. However, sea ice to the east and shallow waters to the north kept this giant berg, named A68, hemmed in. So for more than ...
Melting of ice shelves in West Antarctica speeds up and slows down in response to changes in deep ocean temperature, and is far more variable than previously thought, according to new research published this week in the journal ...
An international team of scientists has shown how much sea level would rise if Larsen C and George VI, two Antarctic ice shelves at risk of collapse, were to break up. While Larsen C has received much attention due to the ...
The Pine Island Glacier in Western Antarctica is not only one of the fastest-flowing ice streams in the Southern Hemisphere; over the past 11 years, four major icebergs have calved from its floating tongue. In February 2017, ...
