碩士 / 國防大學理工學院 / 空間科學碩士班 / 97 / Sea Surface Topography is the difference between geoid and mean sea surface. It is produced by the sea temperature, salinity and ocean current, etc. By the sea surface topography research can determine the shape of the earth and unify the global vertical datum.
In this study, the sea surface topography is determined by satellite altimetry method and marine leveling. The areas of this research are from longitude 119°E to 123°E and from latitude 21°N to 26°N. Satellite altimetry method obtains the sea surface topography determined by the mean sea surface and geoidal undulation model of Taiwan. The primary result of the annual sea surface topography around Taiwan is about 0.4 to 1.4 meters. The difference between the standard dynamic topography and the standard reference surface, the sea surface topography, is determined by marine leveling which utilizes the sea temperature and salinity data which are from depth 0 meters to 1000 meters. The primary result of the annual sea surface topography around Taiwan is about 0 to 2.8 meters. The two methods can recognize Kuroshio Current. Using the interpolation method to get the sea surface topography of tide gauges in Taiwan and the off-shore islands, and to obtain the difference between each tide gauge.
