This study shows the use of L-band SAR data for the monitoring of ice sheet marginal zone on East Antarctica, especially focusing on the extraction of grounding line. ALOS / PALSAR is a SAR sensor which was the latest L-band spacebone sensor. Its 46days revisit cycle seemed to prevent the fine extraction of grounding line, however, this study showed the potential ability for the extraction of grounding line on East Antarctica under the condition of slow flowing velocity of ice sheet. This result encourages the extraction of grounding line by ALOS-2 / PALSAR-2 data thanks to its shorter revisit cycle (14days).
