A recent assessment of glacier flow in Western Palmer Land on the Antarctic Peninsula reveals that sea-ice loss in the region isn’t as drastic as previously reported. Using five different satellites, researchers tracked changes in the speed of more than 30 glaciers over the past 25 years. Their findings provide evidence that Western Palmer Land […]

Survey charts meltwater and streams across Antarctica
For the first time ever, researchers have mapped out the movement of water across Antarctica in an intricate network of lakes and streams. Researchers catalogued satellite images and aerial photographs of the continent starting from the late 1940s. In their analysis of the images, researchers found nearly 700 seasonal systems of interconnected ponds, channels and […]
West Antarctica Ice Sheet is Collapsing
On May 12, 2014, two papers were released which indicated that the Thwaites glacier, a major component of the West Antarctic Ice Sheet, is already under collapse, possibly irreversibly. The first paper, accepted for publication in Geophysical Research Letters, was done by researchers from the University of California Irvine and NASA’s Jet Propulsion Laboratory, and was the subject […]
