We construct a numerical model of the evolution of the structure of an oceanic thermocline in the presence of “salt-finger”
convection. The model explains the formation of a piecewise homogeneous vertical structure of the temperature and salinity
fields in the ocean.

Surface gravity waves formed in the process of motion of an ellipsoidal body submerged in the liquid
O. V. Avramenko 《Physical Oceanography》2000,10(6):533-540
We study the problem of flow around an ellipsoidal body submerged in a liquid half space and obtain the solution for the free
wave surface. The results of numerical analysis reveal the existence of a great variety of modes of motion characterized by
substantially different shapes of the free surface.

We investigate the influence of baroclinic tidal waves on the diffusion of an impurity spot in a continuously stratified liquid.
The equation of turbulent diffusion is solved numerically by taking into account the wave currents. We establish the dependences
of the characteristics of the diffusion process on the parameters of the baroclinic wave and the location of the impurity
spot.

We study distinctive features of the oceanological conditions in the regions of underwater mountains. These conditions are
used as a basic for the selection of hydrological and biological subcomplexes (aqualandscapes) of these regions.

We develop a method for the evaluation of inclinations of the level, which enables one to find them with high accuracy. The
reliability of this method is tested by comparing the numerical solutions for inclinations of the level with analytic expressions.
It is shown that the system of coupled equations for inclinations of the level can be decomposed into two independent equations
with sufficiently high accuracy.

We analyze oscillations of the Black Sea level at 43 points in the north part of the coast. At some points, the data of every-day
measurements are accumulated for more than 100 years. Actually, at all points with minor exceptions, we observe a general
trend toward an increase in the sea level. The amplitude of oscillations of the sea level about the average trend obeys a
normal distribution. We determine numerical characteristics of this distribution.

For the submarine springs of underground water located in the karst cavities of Cape Aiya, we suggest a solution based on
the modification of the model of flow rate of water and application of the formulas of mixing. We also give methodical recommendations
helpful for the reliable determination of empirical parameters under thein situ conditions.

We study the possibilities of the method of laser diagnostics of the composition of multicomponent electrolytic solutions.
In our experiments, we used a four-mirror phase-retarded interferometer operating at three wavelengths from the visible range.
For three-component solutions of chloride salts, we determined partial sensitivities of the measuring system to changes in
the concentrations of each electrolyte for each of the indicated wavelengths.

The process of accumulation of toxic substances by marine organisms is studied on the basis of the kinetic theory of systems
of macroscopic particles (V. I. Belyaev, 1987). The use of stochastic equations makes it possible to evaluate the degree of
accumulation of toxic substances in marine organisms and take into account random variations of their concentrations in marine
environments.

On the basis of analysis of literature data, we consider the regularities of sedimentation of suspended organic matter in
shallow waters. The seasonal variability in sedimentation is demonstrated, and its scheme is constructed involving such classes
of organic compounds as suspended amino acids, fatty acids, and hydrocarbons.

Climatic frontal zones are selected in the thermohaline fields of the Tropical Atlantic by analyzing the many-year-average
seasonal database reduced to the nodes of a one-degree grid. We determine physical characteristics of the frontal zones, study
their spatial and temporal variability, and reveal basic regularities of the appearance of frontal zones in the fields of
thermohaline characteristics.

On the basis of the many-year-average seasonal data array of temperature and salinity presented on a scale of one-degree averaging,
by using a special quantitative criterion, we reveal a climatic frontal zone and determine both its physical and hydrological
characteristics (such as the length width, and thickness of the frontal layer and the temperature, salinity, and density gradients)
and its geographic coordinates. The many-year average seasonal variability of these characteristics is analyzed.

We consider the results of instrumental investigations of specific features of reverberation in the Black Sea and obtain qualitative
dependences of the duration of volume reverberation on the parameters of the Black-Sea underwater sound channel, (width, drop
of the sound velocity, and dimensions of the inhomogeneities of stratification). We also analyse the behaviour of the intensity
of surface reverberation in the far-field zone of acoustic illumination and the influence of bottom reverberation on the detection
of underwater objects.

We use mathematical simulation to study the response of the sea in the region of the Zmeiny Island to the action of winds
of various directions. We describe the processes of reconstruction of circulation and thermohaline structure of waters and,
in particular, the location and dimensions of the zones of upwelling and downwelling caused by water surges depending on the
direction of the wind.

We describe one of possible mechanisms of the formation of anomalies of the cloud field over the North Atlantic and Europe
by using, as an example, the processes developed in the Atlantic-European sector during the natural synoptic season in the
spring of 1996. It is shown that the anomalies of the cloud field can be classified with the use of the index of the North
Atlantic oscillation and the latitude of the center of the Azorean maximum.

On the basis of the data array of many-year average seasonal values of temperature and salinity represented for a one-degree
scale of averaging, by using a quantitative criterion, we select the climatic discharge frontal zone of the Amazon, determine
its physical and hydrological characteristics: length, width, thickness of the frontal layer, temperature, salinity, and density
gradients, and specify its geographical coordinates. We also describe the many-year average interseasonal variability of these
characteristics.

Within the framework of the linear theory of long waves, we study internal waves generated by a barotropic tide in a two-layer
ocean of variable depth taking into account the influence of the Coriolis force. Barotropic waves run over an extended unevenness
of the bottom at an arbitrary angle. This unevenness is regarded as a model of the continental slope and shelf. We establish
the dependences of the amplitudes of generated internal waves on the angle of incidence of the barotropic tide, topography
of the bottom, and stratification.

We solve a nonlinear problem of diffusion from a concentrated source in a moving medium with diffusion coefficient depending
on the scale of the phenomenon, time, and the concentration of impurities. We obtain a family of exact solutions of this problem,
which can be regarded as a generalization of the class of linear problems of diffusion considered earlier for the conditions
of the ocean and atmosphere by Roberts, Ozmidov, Obukhov,et al.
