ICESat First Light Release: From Sea Ice to Ice Streams

The following profile shows the dramatic change in elevation from coastal Antarctica, which is covered in sea ice for most of the year, to the center of the continent. It starts near the Amundsen Sea and travels inward, ending over the West Antarctic Ice Streams where we get a look at this dynamic portion of the polar landscape. (The green elevation profile in this animation is exaggerated vertically by a factor of 10x.)
