Satellite images reveal rapid melting of Antarctica's glacier

Antarctica's glaciers are melting more rapidly than previously known because of climate change, according to a new U.S. Geological Survey report prepared in close collaboration with the British Antarctic Survey. The report is based on the historical and recent satellite imagery, aerial photography and other data, as well as the newest mapping techniques. The study has released maps of recent glacier retreat along Antarctica’s Larsen and Wordie Ice Shelves.

The new report and map of the Larsen Ice Shelf are part of a project to research the coastal change and glaciological characteristics of the entire Antarctic margin. The research is also part of the USGS Glacier Studies Project that is monitoring and describing glacier extent and change over the whole planet using satellite imagery.
