Greenland and Antarctica's ice streams play a key role in transporting ice from polar ice sheets to the ocean. Their flow speed directly influences sea-level rise, making their understanding ...

In Greenland, Dr. Fichtner and a colleague lowered a cable by hand nearly a mile down a borehole, one that other scientists had drilled to extract an ice core. There the cable lay for 14 hours ...

Khan and his colleagues plan to investigate inland sections of other large ice flows in Greenland and Antarctica, with the hopes of improving forecasts of sea level rise (SN: 1/7/20).

Meltwater flows from the Greenland ice sheet into the Baffin Bay near Pituffik, Greenland on July 17, 2022 as captured from the ground on a NASA mission along with University of Texas scientists ...

Greenland’s melting ice will affect millions. In 2020, researchers calculated that Greenland’s ice sheet annually loses about 9 billion tons of water every hour. The total annual freshwater ...

Ice streams like NEGIS carry massive amounts of ice from the interior of the Greenland ice sheet to the ocean, and their rate of flow is directly tied to how quickly sea levels rise.

New radar technology allowing scientists to examine the Greenland ice sheet has revealed that major flows of ice across the continent can change much more rapidly than was previously thought.. The ...

New 3-D Study of the Greenland Ice Sheet Shows Glaciers Falling Apart Faster Than ... Crevasses are wedge-shaped fractures and cracks that open in glaciers where the ice begins to flow faster.

The Greenland ice sheet lost 20 percent more ice than scientists previously thought, posing potential problems for ocean circulation and sea level rise, a study says.

Greenland’s terrestrial ice has existed for about 2.6 million years and has expanded and contracted with two dozen or so “ice age” cycles lasting 70,000 or 100,000 years, punctuated by ...

"Zombie ice" that has broken away from the glaciers that feed them in Greenland is melting and may cause ocean levels to rise by 10 inches if they fully melt.

Ice streams like NEGIS carry massive amounts of ice from the interior of the Greenland ice sheet to the ocean, and their rate of flow is directly tied to how quickly sea levels rise.
