Outline of Final Research Achievements

Using the in-situ gravity data obtained by JARE (the Japanese Antarctic Research Expedition) and GOCE (Gravity field and steady-state Ocean Circulation Explorer) EGMs (Earth Gravity Models), the precise gravity fields around the Japanese Antarctic station, Syowa, have been newly determined. The in-situ data sets employed were the land gravity data since 1967, the surface ship data since 1985 and the airborne gravity data in 2006. Combining these data sets by means of LSC (Least Squares Collocation), the gravity anomalies and the geoid heights have been estimated with the formal errors of a few mGals and a few cm, respectively. A locally determined geoid height at the GPS point in Syowa was compared with the obtained geoid to estimate the sea surface dynamic height. Moreover, GOCE EGMs were evaluated using the airborne gravity data, and the importance of reliable in-situ data has been demonstrated for the purposes.
