The authors show how to determine the ellipsoidal height of the seabed using GNSS measurements and single-beam echo sounders. The authors propose the transition to the system of normal heights referred to the average level of the North Sea as defined by the tide-gauge in Amsterdam to be made using the EGM 2008 model and data from the official Polish quasi-geoid model as well as data from another model distributed by GUGiK (Head Office of Geodesy and Cartography). The article presents also potential errors of the presented method.}, doi = {10.12716/1001.11.04.22}, issn = {2083-6473}, publisher = {Gdynia Maritime University, Faculty of Navigation}, keywords = {EUREF, Gulf of Gdansk, Normal Height System, Maritime Boundary Delimitation, ASG-EUPOS Network, Sea Level, Geodetic Aspects, Polish Economic Zone} }
