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)

This image from the ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) instrument aboard NASA’s Terra satellite shows the termini of the glaciers in the Bhutan-Himalaya. According to a joint press release issued by NASA and the U.S. Geological Survey, the great majority of the world’s glaciers appear to be declining…(Read More)

This pair of false-color images (top) from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), flying aboard NASA’s Terra satellite, shows mountain Kazbek in Southern Russia before and after the collapse of the Kolka Glacier in 2002. On September 20, a collapse of a hanging glacier from the slope of mountain Dzhimarai…(Read More)

As a consequence of its capability to retrieve cloud-top elevations, stereoscopic observations from the Multi-angle Imaging SpectroRadiometer (MISR) can discriminate clouds from snow and ice. The central portion of Russia’s East Siberian Sea, including one of the New Siberian Islands, Novaya Sibir, are portrayed in these views from data acquired on May…(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)

Antarctica’s Mount Erebus may be covered with glaciers, but they do little to cool the volcano’s molten core. The world’s southernmost volcano to show activity during recorded history, Erebus holds a lava lake and occasionally experiences explosive eruptions. In 2004, the reliable presence of a lava lake at this volcano’s summit…(Read More)
