Abstract On the basis of the highprecision global gravity model(EGM2008),combined with multialtimeter data(Geosat/GM data,ERS1/168 data and Envisat data),the gravity anomalies grided in 2′×2′ over China sea and its vicinity (0°N～42°N，102°E～138°E) are determined with the method of deflection of the vertical and inverse Vening Meinesz formula.Compared with the shipboard gravimetry over the South China sea,the results show that the standard error of the gravity anomalies computed with the altimeter data is ±9.43× 10 -5 ms -2. To remove gross error of the residual deflection of the vertical by selecting different criterias, the gravity anomalies computed with the altimeter data and shipboard gravity anomalies were compared and analyzed,the accuracy of residual deflection in the vertical range of 3″~ 5″ is better.
