中文摘要：

In this paper,the admittance function between seafloor undulations and vertical gravity gradient anomalies was derived. Based on this admittance function,the bathymetry model of 1 minute resolution was predicted from vertical gravity gradient anomalies and ship soundings in the experimental area from the northwest Pacific. The accuracy of the model is evaluated using ship soundings and existing models,including ETOPO1,GEBCO,DTU10 and V15. 1 from SIO. The model’s STD is 69. 481m,comparable with V15. 1which is generally believed to have the highest accuracy.
