Jet Propulsion Laboratory https://www.jpl.nasa.gov/ Aug. 18, 2011
These animations shows the motion of ice in Antarctica as measured by satellite data from the Canadian Space Agency, the Japanese Space Agency and the European Space Agency, and processed by NASA-funded research from the University of California, Irvine. The background image from the Landsat satellite is progressively replaced by a map of ice velocity, which is color-coded on a logarithmic scale.
