An instrumental package for monitoring hydrophysical processes (internal and surface gravity waves, including tides, seiches, and wind waves) in the shallow part of the ocean shelf is described as well as methods and approaches.

A radiating hydroacoustic system intended to generate harmonic and phase-shifted hydroacoustic signals in the frequency band of 1 Hz with a center frequency in the range of 19−26 Hz is described. The maximum change in the radiator volume may be as large as 0.0123 m³, which corresponds to a radiated acoustic power of 1000 W at a frequency of 20 Hz in the boundless water space. The prospects of using the system for carrying out research are demonstrated via the results of its testing on the shelf of the Sea of Japan.

Spatiotemporal variability of the internal gravity waves in the Sea of Japan shelf zone (in the Peter the Great Bay) is analyzed basing on the results of the experimental data processing. It is shown...

This paper presents the observation results for the internal wave bore in the coastal region of the Sea of Japan with the use of vertical thermistor chains. The data obtained is interpreted by the mat
