Seeing the Greenland Ice Sheet Through Students’ Eyes
A team of students and faculty advisers revisited the site of pioneering geosciences expeditions from the 1920s, looking to introduce young researchers to polar science.
Freshwater Pools Show Antarctica Is More Vulnerable Than We Thought
East Antarctica’s lakes cluster in patterns similar to those on Greenland’s ice sheet, which is melting rapidly.
Grim Report on Climate Change Impacts on Oceans and Cryosphere
A new report by the Intergovernmental Panel on Climate Change states that bold actions can prevent significantly worse impacts.
New Earth Orbiter Provides a Sharper Look at a Changing Planet
A first look at data from NASA’s laser altimeter mission ICESat-2 reveals very high resolution 3-D profiles of ice on land and sea, forests, and shallow bodies of water.
Ceres: Evolution of the Asteroid Belt’s Icy Giant
A new special collection in JGR: Planets explores how ice has played a key role in the development of the landscape on the surface of Ceres.
Vintage Radar Film Tracks What’s Beneath Antarctic Ice
The newly digitized data double the timescale of ice-penetrating radar monitoring in some of the fastest changing areas of Antarctica.
Is the Northern Permafrost Zone a Source or a Sink for Carbon?
Thawing permafrost could release large amounts of carbon into the atmosphere, but finding out how much requires better collection and curation of data.
Microbes Spotted on Blades of Ice High in the Andes
Researchers discover microbial life on ice spires known as penitentes on the arid, sunlight-blasted upper reaches of Llullaillaco, one of the best earthly analogues for Mars.
A Nearly 100-Year-Old Physics Model Replicates Modern Arctic Ice Melt
The model was previously used to describe the behavior of ferromagnets in the presence of external magnetic fields.
