| Abstract: | For solving the problems that downward continuation of the space gravity anomaly can not be used in downward continuation of sea surface gravity anomaly,on the basis of Prey principle used to compute gravity in the surface-layer of the earth,and with considering the density of sea water and sea bottom topography,two new methods are proposed.The experimental results show that the new methods are valid and effective. |

| Keywords: | gravity anomaly of sea surface vertical gradient of gravity anomaly downward continuation cylinder method geometry method |
