Sea Ice950 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. Feb 05, 2009

Antarctica & Sea Ice804 viewsReduced-resolution image from QuikScat sigma-0 measurements. This image shows Antarctica and the surrounding sea ice on July 1999. Feb 05, 2009

Allan Hills1305 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.Feb 05, 2009

Antarctic Snow Dunes1452 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.Feb 05, 2009
fimbul_map.jpg
Fimbul Ice Shelf1412 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 retreatFeb 05, 2009
icestreamb_map.jpg
957 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.

1204 viewsThis image shows the annual climatology melt for 2007 from Greenland Ice Sheet Melt Characteristics Derived from Passive Microwave Data. Feb 05, 2009
uncorrected_map.png
954 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.Feb 05, 2009

ICESat/GLAS tracks over Hektoria Glacier, Antarctica1197 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. Feb 05, 2009
