| Abstract: | The vertical deflection theorem of satellite altimetry has become the optimal way to research the marine gravity field, which includes computing the vertical deflections from the altimeter data and determining the marine gravity field from the vertical deflections, Three main approaches of computing the vertical deflections from the altimeter data presented by Sandwell, Olgiati and Hwang, respectively, have been studied, And two theorems of determining the marine gravity field from the vertical defelctions proposed by Molodenskii and Hwang, respectively, are compared, The paper severs for determining scientifically the marine gravity field from the altimeter data, |
