Snowdrifts prove less ephemeral than they might seem, occurring in the same places year after year.
Properties
Antarctic Ice Cores Might Be Older Than Dirt
Using cosmogenic nuclide dating, scientists determined a 10-meter core just below the surface to be over a million years old.
Light Permeates Seasonally Through Arctic Sea Ice
The transmission of sunlight through Arctic sea ice depends on the presence of ice, snow, and melt ponds, data collected over 6 years reveal.
Icy Interactions
Complex interactions between ice sheets and other components of the Earth system determine how ice sheets contribute to sea level rise.
A Novel Way to Map Debris Thickness on Himalayan Glaciers
By combining changes in elevation with other data, scientists have developed a method for estimating the thickness of debris covering glaciers on whose water more than 800 million people depend.
Ice-Penetrating Radar Reveals Age of Greenland Ice Sheet Layers
First comprehensive analysis of deep radar data gives insight into the dynamics and history of the Greenland Ice Sheet.
Tracking the Sources and Sinks of Antarctica’s Subglacial Waterways
Researchers examined the water flowing into and out of several Antarctic ice streams to determine the cause of a recent observed slowdown of some of these ice streams.
