Antarctic Glaciers Accelerate in Wake of Ice Shelf Breakup:
This satellite image from NASA's MODIS sensor aboard the Terra spacecraft shows the Larsen B Ice Shelf region on 1 November 2003. Red dots indicate sites where ice flow speed was measured using more detailed Landsat 7 images. The colored lines track the retreat of the Larsen B Ice Shelf during the past 6 years, and the black line shows the coastline, or "grounding line," where the thick ice begins to float off the sea floor. Blue lines on the glaciers show the location of laser elevation profiles from ICESat. A weather station location marked in the upper right of the image map ("Matienzo AWS") has tracked atmospheric warming in summers over the past 30+ years in the region.
