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.

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.
