The aim of the paper is to analyze data obtained during sounding the Gdansk Bay sea bed by means of theparametric echo-sounder. The accuracy of the sea bottom structure investigation needs correct configurationof research equipment and proper calibration of peripheral devices (GPS, heading sensor, MRU-Z motionsensor and navigation instruments which provide necessary data to bathymetrical measurement system,enabling its work with full capability. The parametric sub-bottom profiler delivers two types of data whichinclude different information: envelope and pure echo signal sampled without processing. The first is usedto present echograms in real time and the second one is stored during sounding and the obtained datacan be analyzed by using post-processing software. Differences in the results are presented and discussed.And, are described also criteria taken into account during determination of the measurement areas andselection of different configurations of the software according to the information to be obtained fromtrials. Complementary information can be achieved from processing the data by means of the proceduresoffered by Matlab software, which allows for a clear 3D presentation of the results.
