The issue presents researches of the ocean dynamics on the basis of physical and mathematical model approaches and extensive material of in situ observations, application-oriented tasks of hydroacoustics are considered, georisks at construction of sea pipelines are discussed. A review of oceanologic models of not hydrostatic dynamics for the last several decades is provided. The modulation phenomenon of short infragravity waves by the tides on the shelf of Sakhalin Island is analyzed. The effect of subinertial sea level atmospheric pressure fluctuations on the inflow intensity of the surface Atlantic waters through the Strait of Gibraltar and its impacts on the dynamics of the Alboran Sea is studied. The eigenvalue spectra for a model problem describing formation of the large-scale intrusions in the Arctic basin is considered. The Mapping of the Baltic Sea by the types of density stratification in the context of dynamics of internal gravity waves is discussed. The flooding mechanism in the Kuban River Delta, caused by the rise of the level of the Sea of Azov due to atmospheric impact, is investigated with the use of numerical modeling. the effect of vertical heterogeneity of acoustic properties of sea ice on phase of reflection coefficient of acoustic low-frequency harmonic plane wave at its normal incidence on sea water-ice interface is investigated by a method of model experiment with application to the task of remote measurement of the Arctic Sea ice cover thickness from under water. The verbal behavior of beluga whale Delphinapterus leucas acoustically stimulated by noise-like signal during demonstration of video images is studied. A methodical approach to risk assessment in the construction and subsequent operation of the offshore part of pipelines associated with the manifestation of natural and other factors is suggested.
