The Shirase Glacier is the largest in the Lutzow Holm Bay and is well known as the fastest-flowing ice stream in Antarctica. Although several attempts have been made to measure ice flow velocities of the glacier using ground measurements and remotely sensed data, continuous measurement over a long period has been impossible due to severe environmental conditions and the lack of datasets from continuous observation. This report of our preliminary ice-flow estimations of the Shirase Glacier correlates the amplitude images with the available synthetic aperture radar (SAR) data. We propose to determine ice-flow velocities using this image correlation. We apply our technique to the SAR data obtained by observing the Shirase Glacier to determine and analyze the ice flow velocities in the summary
