Over the past several years, determination of the sea surface topography using satellite altimetry has been greatly improved due to the implementation of a technique which simultaneously solves for the sea surface topography, the gravity field of the Earth, and the satellite orbit [Tapley et al.,1988; Marsh et al., 1989; Nerem,1989; Engelis and Knudsen; 1989]. The sea surface topography, ζ, is defined as the deviation of the ocean surface from the geoid due to the geostrophic component of the ocean currents.
