Velocities of Outlet Glaciers, Ice streams, and Ice shelves, Antarctica, From Satellite Images
Entry ID: USGS_outletglaciers

Abstract: Changes in global climate and sea level are intricately linked to changes in
the area and volume of polar ice sheets. Thus, melting of the ice sheets may
severely impact the densely populated coastal regions on Earth. Melting of the
West Antarctic ice sheet alone could raise sea level by approximately 5m. In
spite of their importance, the current mass balances (the net ... View entire text

Quality We use two methods to determine the glacial velocities: an interactive one in
which we visually trace crevasse patterns (Lucchitta and others, 1993) and an
autocorrelation program developed by Bindschadler and Scambos (1991) and
Scambos and others (1992). First, we digitally co-register the images by using
