Outline of Final Research Achievements

This study aims to detect in the marginal fluctuation of the Antarctic ice sheets of the past 45 years long the Soya Coast, by comparison of two types of digital elevation models of aerial photographs and satellite images. As a result, the catalog of the stereo pair images of since the 1960s, covering this region has been completed. The actual result of the analysis of the surface elevation change and the terminus position of the Langhovde glaciers shows that its terminal position is retreated significantly from 1975 to 2007, while surface elevation was slightly increased or steady state.
