As glaciers flow outward from the Greenland Ice Sheet, what lies beneath them offers clues to their role in future ice thinning and sea-level rise contribution. Outlet glaciers are rivers of ice flowing within the cracks of the bedrock and draining into the surrounding sea. They retreat and start to […]

Kötlujökull, the fourth largest glacier in Iceland, hosts abundant microorganisms sustained by hydrogen produced by weathering of basaltic bedrock. Credit: Eric S. Boyd. Using years of data collected from ice-covered habitats all over the world, a Montana State University team has discovered new insights into the processes that support microbial […]

Peterman Island, Graham Land, Antarctica. A new study finds that atmospheric rivers in the Southern Hemisphere have been gradually shifting toward the South Pole for the past 40 years, a trend which could lead to increased rates of ice melt in Antarctica.

The unstable terrain that poses a landslide threat lies between the Cascade Glacier and Barry Arm Glacier, which has been steadily retreating over the last decade. The above satellite images show the glacier’s retreat from 2013 (above) to 2019 (below). Credit: NASA Earth Observatory images by Lauren Dauphin, using Landsat […]

NASA scientists traverse Antarctica’s icy landscape, towing scientific instruments and cold-weather gear with them. The team was tasked with collecting ground data to verify the accuracy of measurements made by the IceSat-2 satellite.

Satellite imagery has revealed that two of the fastest-changing glaciers in Antarctica are fracturing and weakening faster than ever – the first step towards the glaciers disintegrating and causing sea levels to rise dramatically. Using observations from ESA, NASA and USGS satellites, the researchers explored the Pine Island and Thwaites Glaciers in the […]

Lake Imja near Mount Everest in the Himalaya is a glacier lake that has grown to three times its length since 1990. Credit: Planetary Science Institute/Jeffrey S. Kargel In the largest-ever study of glacial lakes, researchers using 30 years of NASAsatellite data have found that the volume of these lakes worldwide […]
