Allan Hills914 viewsThe Allan Hills are located on the flanks of the TransAntarctic Mountains. Ice upwells onto the hills where combinations of winds and solar insolation cause the ice to quickly ablate. Meteorites that once fell over a large region of East Antarctica have been carried by glacier motion into this small locality.

Antarctic Snow Dunes1075 viewsExtensive snow dunes wrinkle the surface of large parts of East and West Antarctica. The dunes are up to 100 kilometers long and separated by 2 to 4 kilometers, but only a few meters high. Comparison of modern satellite images with images acquired four decades earlier reveals that the dunes are nearly motionless.

Fimbul Ice Shelf1015 viewsThe Fimbul Ice Shelf is punctuated by numerous ice rises that occur where isolated rocky islands are covered by ice. Ice shelves may be particularly sensitive to changes in climate, and recently ice shelves in the Antarctic Peninsula have experienced rapid retreat

ICESat/GLAS tracks over Hektoria Glacier, Antarctica940 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.

1071 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.

692 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.
