	abstract = {The article presents a method of determining the level of the seabed in the Polish reference system. 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.},
