Errors of depth measurement are one of the most important problems in area of bathymetric data processing. The authors examined a data set aquired with the multibeam eehosounder Sim rad EM3000 in order to estimate the character of errors. For every measurement line formed by the survey points, the theoretical model of this fragment of bottom was defined using approximation. The differenees between this model and the survey points were treated as the measurement errors, which appeared to have a random distribution. The correlation of error value and angle between the beam and the vertical line could be observed. 99.7 % of er- ror values was smaller than 7 cm for depths between 10 and 20 m, while mean value of errors was approx. 3 cm.
