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.

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.

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
