The purpose of this article is to present the results of investigation to search for buried objects. The paper will contain echograms and other means of visualization from buried pipe placed between area of W?adys?awowo and gas platform and interesting in terms of the number of small and medium-sized unidentified objects found in the muddy bottom at different depths localized in the Gulf of Puck - results will be presented also with post-processing tools available mainly using the algorithms provided with the Matlab programming environment. Trails on Gulf of Gda?sk were done by Hydroacoustic Institute research team several times. Using small measurement vessel: "Windspeel" various aspects of the survey were discussed like: classification of sediments, tests with different sounding pulses properties and classifying them according to the type of task, preparing the most optimal configuration of additional devices to obtain complete data about natural conditions: above water (weather station), on the measurement yacht: pitch, roll and heave sensor to stabilize antenna beam, navigation units (GPS), Radar, AIS, NOAA devices and in water e.g. speed of sound profile. In this article authors would like to focus on two interesting, described at the beginning, aspects.
