Researchers from NASA and the University of California, Irvine (UCI) have gained an unprecedented view of ice melting on the floating undersides of glaciers. In the process, they detected the fastest ongoing rates of glacier retreat ever observed in West Antarctica.
Published Oct 30, 2016More than 30 years of ice velocity data are helping scientists tease out how mountain glaciers respond to climate change.
Published Sep 11, 2019To understand how fast-moving glaciers are changing the ice sheets, scientists devised a method to map elevation change using data from ICESat.
Published Oct 3, 2009The remnant of Antarctica’s Larsen B Ice Shelf is flowing faster, becoming increasingly fragmented, and developing large cracks.

Satellites detect changes in the height and velocity of ice in an area that was thought to be relatively stable and quiet.
Published Dec 11, 2018The image above depicts the region of West Antarctica where scientists measured ice speed. The fast-moving central ice streams are shown in red. Slower tributaries feeding the ice streams are shown in blue. Green areas depict slow-moving, stable areas. Thick black lines depict the areas that collect snowfall to feed their respective ice streams.
