Sea ice monitoring in Lutzow-Holm Bay by using European Remote sensing Satellite-2 (ERS-2) data was conducted during the wintering period of the 43rd. Japanese Antarctic Research Expedition. ERS-2 Synthetic Aperture Radar (SAR) data were directly received and processed at the Syowa Station. Ground truth data were acquired almost simultaneously with ERS-2 observations.
This paper describes the time-dependent change of backscattering coefficients for various sea-ice types found in Lützow-Holm Bay by using ERS-2 SAR data acquired in 2002 and 2003. The mechanisms which cause various backscattering change of sea-ice were investigated from the ground truth data.
