Abstract: | Sea gravity measurements were carried out over the East China Sea and its neighbourhood using a ZYZY-type Sea Gravimeter in 1977 and 1979.Maps of the free air gravity anomaly, the Bouguer gravity anomaly, crustal thickness and synthetic gravity across the Ryukyu trench have been compiled. The gravity anomaly distribution and the characteristics of the crustal structure are discussed. |
