Abstract

The movement of Shirase glacier and Kaya glacier in Lutzow-Holm Bay in Antarctica was analyzed using LANDSAT/TM, MSS, MOS-1/MESSR and ERS-1/SAR data. Through multi-temporal analysis, the velocity of the Shirase glacier floating ice tongue was estimated to be 2.9 km/year for 1988-1989 and 2.6 km/year for 1989-1991. ERS-1/SAR image was compared with MOS-1/MESSR near-in image for Kaya glacier and sea ice. Floating ice tongue edges and fast ice in both images show clear differences, which suggests the importance of multi sensor analysis for glacier study
