Wilkins Ice Shelf2598 viewsAVHRR image acquired on 14 January 1999 showing the once intact Wilkins Ice Shelf, Antarctica. View pre- and post-collapse images of the ice shelf at the Images of Antarctic Ice Shelves Web site.

Ross Ice Shelf2373 viewsAVHRR image of West Ross Ice Shelf, Antarctica on 27 January 2001.

Antarctic Snow Dunes1655 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 Shelf1630 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

Allan Hills1504 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.

ICESat/GLAS tracks over Hektoria Glacier, Antarctica1344 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.
icestreamb_map.jpg
1102 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.

Sea Ice1081 viewsArctic sea ice image produced from daily-averaged QuikSCAT sigma-0 measurements from NASA SCP Arctic and Antarctic Ice Extent from QuikSCAT, 1999-2004 Dataset.
uncorrected_map.png
1065 viewsThis map shows the spatial distribution of the rate of elevation change from the Elevation Change of the Southern Greenland Ice Sheet from 1978-1988 data set. The data was acquired from Seasat and Geosat radar altimeter data. It shows a 2000 m surface elevation contour, the ice divide, and the locations of nine shallow and three deeper ice cores in the study area.
