A Challenge to the Detection of Regional to Local Scale Ice Sheet Movements in Antarctica by the Combination of In-situ Gravity Measurements and Gravity Satellite Data

Abstract. The ice sheet thinning rate of the Shirase Glacier drainage basin in the Japanese Ant-arctic Research Expedition area is estimated about 10-20 cm/year. The detection of the signals by means of precise gravity measurements not only brings useful information for glaciological studies, but al...

Description
Summary:Abstract. The ice sheet thinning rate of the Shirase Glacier drainage basin in the Japanese Ant-arctic Research Expedition area is estimated about 10-20 cm/year. The detection of the signals by means of precise gravity measurements not only brings useful information for glaciological studies, but also contributes to the CAL/VAL purpose of the gravity mission data. In this study we propose an effective configuration of in-situ precise gravity measurements on the ice sheet, and discuss the possible linkage with the gravity mission data.
