Abstract

Abstract

There is a close correlation between sea level slope and height datum, in which geodesylists and oceanographers are interested.The accuracy of geodetic leveling is discussed.The existent difference between geodetic leveling and tide station is investigated, and this difference comes from the sea level slope, and the sea level slope mechanism caused by ocean current, air pressure and breaking wave is analyzed, the geoid disturbance computed by three-dimensional distribution of sea water density is presented and this disturbance materially reflects the sea level slope.According to the computation the disturhance quantity possesses about 73% of the sea level slope, which indicates that the density anomaly of sea water is primary cause of the sea level slope.
- sea level slope, ocean current,
