The image above shows the snow depth in the Northern Hemisphere on December 7, 2002, derived from the National Space Development Agency of Japan’s (NASDA) Advanced Microwave Scanning Radiometer for EOS (AMSR-E) on the Aqua satellite. Low frequency channels (6.9 and 10.7 GHz) of AMSR-E may improve upon the snow…(Read More)

Iceberg B-15A was the largest iceberg in the world (~11,000 square kilometers) when it broke away from Western Antarctica’s Ross Ice Shelf in March 2000. The Multi-Angle Imaging SpectroRadiometer (MISR) acquired these views of the new iceberg B-15J (resting against Ross Island) and B-15A (now free to drift into…(Read More)

The left-hand panel is a natural-color view from MISR’s downward-looking (nadir) camera. The center panel is a multi-angular composite from three MISR cameras, in which color acts as a proxy for angular reflectance variations related to texture. Here, data from the red-band of MISR’s 60° forward-viewing, nadir…(Read More)

Over the past two and a half years, several large icebergs have separated from the Ross Ice Shelf in Antarctica and some have made their way out into the Pacific Ocean to melt. Mainland Antarctica lies across the left side of the image. The Ross Ice Shelf is the solid, uniform white mass on the…(Read More)

The Amery Ice Shelf is an important dynamic system responsible for draining about 16 percent of the grounded East Antarctic ice sheet through only 2 percent of its coastline. Most of the mass input to the system occurs from the Lambert Glacier and several other glaciers. Mass loss from the system occurs through basal melting…(Read More)
