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 […]

The prevailing theory has been that sea ice can act as a lid to keep carbon in the ocean from escaping back to the atmosphere. However, researchers at MIT have now identified a counteracting effect that suggests Antarctic sea ice may not be as powerful a control on the global […]

A surging glacier in the St. Elias Mountains, Canada. Credit: Gwenn Flowers New model answers longstanding question of how these sudden flows happen; may expand understanding of Antarctic ice sheets. About 10 percent of the Earth’s land mass is covered in glaciers, most of which slip slowly across the land […]

It’s amongst the best ocean-floor imagery obtained anywhere around Antarctica DOWDESWELL ET A Scientists are learning just how fast the ice margin of Antarctica can retreat in a warming world. They’ve identified features on the seafloor that indicate the ice edge was reversing at rates of up to 50m a […]

Denman Glacier, February 26 – 28, 2020. Using a combination of satellite sensors, scientists recently found that Denman Glacier has been retreating both above and below the water line. That one glacier in East Antarctica holds as much ice as half of West Antarctica, so scientists are concerned about its […]
