Rapid Thinning of Glaciers Seen
After Collapse of Antarctic Ice Shelf

NASA has released satellite photos that vividly depict the precipitous thinning and retreat of two Antarctic glaciers following the disintegration of the Larsen B Ice Shelf. READ MORE

 




Several NASA photographs vividly depict the precipitous thinning and retreat of two Antarctic glaciers following the 2002 disintegration of the Larsen B Ice Shelf, which had acted as a buttress slowing the flow of numerous glaciers into the sea. The 2002 photo, top, shows the glaciers covering much of nearby mountain ridges and the termini, or end points, of the glaciers are not visible. The 2012 photo shows that the thinning glaciers now cover considerably less of surrounding mountain ridges and the termini of both glaciers are visible. The 2012 image also shows the numerous crevasses that have formed as the glaciers have thinned. A third NASA color visualization, bottom, depicts how the lower reaches of the glaciers, seen in red, have lost as much as 720 feet of vertical thickness since 2002. (NASA)
