英文摘要：

The Mean dynamic topography （MDT） is the deviation of mean sea surface from geoid field. Applying the geostrophic equilibrium theory, the surface geostrophic circulation could be determined by the gradient of MDT. According to the definition of MDT, its determination requires the mean sea surface and geoid data. Following the great developments of the satellite geodetic techniques, the mean sea surface height and global geoid fields could be determined precisely with considerable spatial resolution from space. These high quality mean sea surface height and geoid data enable us to precisely determine the geodetic MDT at smaller spatial scale, and enhance the research on geostrophic current. This paper summarized the research progress in both geodetic MDT and geostrophic current from data quality, calculation methods of MDT and geostrophic currents, spatial resolution analyses, errors analyses, and multiple-data combination. Furthermore, we present the main problems and give some recommendations of the following research work for the above researches.
