• 論文の詳細を見る

• In polar regions, there are relatively sparse geophysical and geodetic data for the severe environment. This paper presents the result of gravity observations obtained along the traverse routes from Syowa Station to Dome Fuji Station, East Antarctica. The obtained gravity values were determined within the accuracy of 1 mgal. Gravity values should be available to examine gravity changes for each station. The Bouguer gravity anomalies calculated show the large negative anomaly trending inland toward Dome Fuji, in the southern most observation area, at about -200 mgal. This indicates that the Bouguer gravity anomalies express the depth of the Moho discontinuity, that is, thickening of the crust inland, which in turn suggests that the depth of the Moho discontinuity around Dome Fuji Station is about 45 km.
