内容記述 |
Free-air and Bouguer gravity anomaly maps around the Japanese Antarctic stations have been newly compiled. The area concerned is located approximately from 60°S to 80°S and from 20°E to 50°E. Data sources are, the land gravity measurements by Japan and other countries, the surface ship measurements by Japan, and the satellite altimetric gravity anomaly. The accuracy of these maps, especially in the coastal areas, has been extremely improved because of the use of the most updated surface ship gravity data in the calibration of the satellite altimetric gravity. Using the gravity maps obtained, and taking the distribution of the ice sheets over the land into consideration, the present status of isostatic balance was examined. The results show that isostatic compensation beneath the continental and oceanic areas seems to be very well, although there exist some anomalous features which may reflect the local crustal structures. |
