The Pine Island Glacier is the largest discharger of ice in Antarctica and the continent's fastest moving glacier. This area of the West Antarctic Ice Sheet is also believed to be the most susceptible to collapse. The evolution of this glacier is therefore of great interest to the scientific community. It is an area of Antarctica which is experiencing rapid changes. The grounding line of Pine Island Glacier is retreating, the glacier is thinning rapidly, and its ice flow is accelerating. Additionally, the sea ice cover in front of the glacier has been decreasing steadily for several decades. The Landsat Image Mosaic of Antarctica (LIMA) is a data product funded by the National Science Foundation (NSF) and jointly produced by the U.S. Geological Survey (USGS), the British Antarctic Survey (BAS), and the National Aeronautics and Space Administration (NASA). The LIMA data shown here uses the pan-chromatic band and has a resolution of 15 meters per pixel. The 13 swaths used to generate this sample mosaic where acquired between December 25, 1999 and December 31, 2001. The elevation data shown has no vertical exaggeration (1x) and is courtesy of the Radarsat Antarctic Mapping Project (RAMP) Digital Elevation Model (DEM). Note: This is the Pine Island Glacier which is a broad glacier flowing WNW along the south side of the Hudson Mountains into Pine Island Bay, Amundsen Sea. Animator: Lori Perkins (NASA/GSFC).
