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)

Claire Parkinson of NASA’s Goddard Space Flight Center analyzed the length of the sea ice season throughout the Southern Ocean to obtain trends in sea ice coverage. Parkinson examined 21 years (1979-1999) of Antarctic sea ice satellite records and discovered that, on average, the area where southern sea ice seasons have lengthened by…(Read More)
