| Research Abstract |
It is important to reveal the variation in ice mass of the Antarctic ice sheet caused by global climatic change. The objective of this project is to reveal the effect of variation in the end of ice sheet on the dynamical behavior of drainage basin in Antarctic ice sheet. Japanese Antarctic Research Expeditions (JAREs) have collected the ground data on surface topography, bedrock topography, surface snow conditions and surface mass balance in the Shirase drainage basin of which summit of the ice sheet (Dome Fuji). The dynamical behavior of Shirase Glacier is very important to understand the response of the Shirase drainage basin to global climatic change. It is difficult to approach Shirase Glacier because of the existence of many crevasses. It is possible to collect various information of the glacier using Synthetic Aperture Radar (SAM).
In order to investigate the effect of variation of the end of ice sheet on the dynamical behavior of drainage basin in Antarctica, the analysis system was built using Geographic Information System (GIS). It is possible to compare ground observation data such as surface topography, snow surface conditions and surface mass balance with image data by Synthetic Aperture Radar (SAR). And to reveal the mechanism of ice sheet change, the analysis of multi frequencies radio echo sounding observation data on the internal structure of the ice sheet.
