Research and the Establishment of the Bohai Sea Separation Model Based on the Model Difference Method

Abstract

Sun, C.; Ma, F.; Zhou, X., and Ning, L., 2015. Research and the establishment of the Bohai Sea separation model based on the model difference method. 0749-0208.With the development of marine surveying technology, there is an urgent need for solving the discontinuity problem of the depth datum. In this paper the difference model method based on the relationship between the mean sea level and the theoretical depth datum has been approached. Taking Bohai as the study area the deviation model has been built and its accuracy has been analyzed. ADDITIONAL INDEX WORDS:Seamless vertical datum, depth datum, mean sea surface, model difference method, separation model.
