The rate of glacier ice flow is more sensitive to stress than previously calculated, according to a new study by MIT researchers that upends a decades-old equation used to describe ice flow. Stress in ...

A University of Otago—Ōtākou Whakaihu Waka-led study is developing innovative methods to accurately predict how ice sheets and glaciers are deforming and moving. Just published in the journal Nature ...

A glacier's flow depends on how microscopic defects move through the ice, according to new research that also yielded a new model for predicting how glaciers will flow, ultimately contributing to ...

Laboratory experiments designed to deform ice at its pressure-melting temperature were like grabbing a bagel at the top and the bottom, then twisting the two halves to smear the cream cheese in the ...

Melt water flowing through ice sheets via crevasses, fractures and large drains called moulins can carry warmth into ice sheet interiors, greatly accelerating the thermal response of an ice sheet to ...

Using satellite data and the physics of ice flow, researchers have mapped Antarctica’s hidden subglacial bedrock landscape – one of the Solar System’s least mapped planetary surfaces – in ...

A NASA researcher finds that the amount of sea ice that moves between Greenland and Spitsbergen, a group of islands north of Norway, is dependent upon a “wave” of atmospheric pressure at sea level. By ...

This polarized light image shows ice grains deformed in experiments with the ring-shear device in Neal Iverson's Iowa State laboratory. The experiments show that grains, on average, grow about 3 times ...

AMES, Iowa – Neal Iverson started with two lessons in ice physics when asked to describe a research paper about glacier ice flow that has just been published by the journal Science. First, said the ...
