In this article, the results of sounding the Gdansk bay sea bed by using a SES-2000 Standard parametric sub-bottom profiler are described. But the main goal of this paper is to describe the results.Abstract:
The main goal of this paper is to describe the results of sounding the Gdansk Bay sea bed by using a SES-2000 Standard parametric sub-bottom profiler. Quality of data obtained during trials depends inter alia on a proper location of transducer array to reduce influence of pitch, roll and heave motions as well as ship self noise (resulting from bubbles due to propeller and flow around hull, vibration generated by main engine and auxiliary devices). Furthermore, calibration of complementary units such as GPS, heading sensor, MRU-Z motion sensor and navigation devices make sea-bed investigating system capable of working with its whole capability. Results of so prepared surveys have been presented and discussed. They contain also an elaborated map of Gdansk Bay with preliminarily classified sea-bed materials and description of most interesting areas.read more

Underwater Acoustic Imaging of the Sea
TL;DR: In this article, it is explained why acoustic waves are used in underwater imaging. And the passive and active systems for underwater observation are presented, most of them originated from our own investigation, which is illustrated by acoustic images.

Propagation of Ship-Generated Noise in Shallow Sea
TL;DR: In this article, the authors presented results of numerical investigations based on real data dealing with noise produced by a selected floating unit (ship) for selected characteristic spectral components, for the shallow sea model of definite physical parameters such as acoustic wave propagation velocity, geometrical dimensions (water depth) and seabed acoustic parameters as well.

Nonlinear Properties of the Gotland Deep – Baltic Sea
TL;DR: Grelowska et al. as mentioned in this paper investigated the nonlinear properties of the South and the Central Baltic by means of thermodynamic method, and the results of their investigation were presented. But they did not consider the effects of nonlinear distortion of elastic waves.

Time-dependent seafloor acoustic backscatter (10-100 kHz).
TL;DR: A time-dependent model of the acoustic intensity backscattered by the seafloor is described and compared with data from a calibrated, vertically oriented, echo-sounder operating at 33 and 93 kHz, finding practical constraints on roughness spectrum parameter settings appropriate for echo-envelope-based sediment classification procedures.

Detection of Objects Buried in the Sea Bottom with the Use of Parametric Echosounder
TL;DR: In this paper, the results of a in situ research main task of which was to detect objects buried, partially or completely, in the sea bottom were presented. But, the use of classic hydroacoustic devices such as the sidescan sonar or multibeam echosounder proves ineffective.
