ICESat/GLAS tracks over Hektoria Glacier, Antarctica1720 viewsThis figure shows an image map of three ICESat/GLAS tracks from the eight-day missions that were used to investigate the response of Hektoria Glacier in the Antarctic Peninsula to the loss of the Larsen B Ice Shelf in March of 2002. The three tracks cross the lower portion of the glacier at an angle. In dark blue are contours showing the level of speed increase in meters per day since breakup of the shelf.
2102 viewsThis Landsat image of Crane Glacier on the Antarctic Peninsula is overlain with ICESat and Airborne Topopgraphic Mapper (ATM) tracks. ATM is a lidar sensor that is now part of the IceBridge mission. Over time, ICESat and ATM measurements, together with visible imagery, can detect thinning of the ice and accelerated flow of ice into the ocean. Large glaciers such as Crane have the potential to contribute significantly to sea level rise.

1500 viewsOne of the most studied and interesting ice streams in Antarctica, Ice Stream B shows a number of features that indicate past changes and ongoing evolution. In this subscene the upstream ends of several ice stream shear margins are highlighted. Characteristic crevasse patterns, nicknamed "chromosomes," mark the ends of several of these margin traces.
