Optimal interpolation of the data of remote sensing of the sea surface

We analyze the statistical structure of the data of remote sensing of the fields of surface temperature and the concentration of chlorophyll in the northwest part of the Black Sea with an aim to apply the method of optimal interpolation to the restoration of the maps of these fields according to the restricted amounts of data. We determine the scales of smoothing for the selection of the random components of the fields and estimate their difference from the statistical model uniform and isotropic over the space correlation coefficients. The functions of spectral densities are constructed along various sections and the best intervals of discretization of the fields required to perform the optimal interpolation with given accuracy are determined. It is shown that the construction of the maps of fields under the conditions of controlled accuracy of reconstruction of their values remains possible even if the amounts of the input satellite data are significantly decreased. We consider a procedure of evaluation of the best possible amounts of data required for the use of the method of optimal interpolation. Some examples of application of this procedure to the data of remote sensing of the fields of surface temperature and the concentration of chlorophyll are presented.     

Parametrization of the Biochemical Processes of Oxidation and Numerical Modeling of the Seasonal Behavior of the Distribution of Oil Hydrocarbons in the Aerobic Zone of the Black Sea

We discuss specific features of the space distribution and the processes of assimilation and oxidation of the dissolved and emulsified fractions of oil hydrocarbons in Black-Sea waters and study the methods of parametrization of these processes proposed in the literature. We develop a procedure of parametrization of the processes of degradation of oil hydrocarbons taking into account their complex chemical compositions, characteristics of chemical and microbiological processes, and temperature dependences of these processes and perform numerical experiments aimed at the reconstruction of the seasonal variations of the large-scale space structure of the distribution of oil hydrocarbons in the aerobic zone of the Black Sea.     

Reconstruction of the surface temperature fields according to the fragmentary data of remote sensing

We propose a gap-filling method for the data of remote sensing of the hydrophysical and biological characteristics of the water surface. The proposed method of reconstruction is based on the representation of the fields of surface characteristics as the sums of certain numbers of empirical orthogonal functions (EOF) making the largest contributions to the total variance of the field. According to the fragmentary data obtained as a result of processing of the satellite images for the summer season, we construct estimates of the mean field and of the four-dimensional space covariance function of the surface temperature of the Black Sea. The coefficients of expansion are computed by the method of least squares or determined with the help of a genetic searching algorithm. The results of numerical experiments show that the proposed method is quite promising for applications in the problems of gap filling in the available satellite data.     

Diagnostics of the mesoscale water exchange on the basis of statistical characteristics of the distribution of normalized radiance

A new approach is suggested for the diagnostics of manifestations of water exchange in the field of normalized radiance and automation of the analysis of digital images of the water surface. The approach is based on the application of a set of statistical characteristics of a radiance relief as an integral indication of local inhomogeneities in the water medium and provides for the estimate of these characteristics over small regions (frames) of the basin studied using multispectral information. Using the example of the SeaWiFS scanner data on the evolution of an eddy dipole in August 1998 in a study region with a size of 160 × 160 km in the northwestern part of the Black Sea, it was shown that the estimates of a number of statistical characteristics of spectrally different radiance reliefs found in the frames with a size of 40 × 40 km significantly depended on the presence of fragments of an eddy dipole or other structures in these frames. A set of such characteristics made possible reliable differentiation of radiance reliefs by the degree of randomness, by the orientation of the inhomogeneities that form the relief, and by other properties caused by the variability of the light scattering and light absorbing admixtures in the sea medium in the course of the water exchange. The approach does not require any preliminary information about the object of observations. It is promising in the basins with moderate water transparency and vertical inhomogeneity of the upper layer available for remote profiling.     

Joint Distribution of Wave Periods and Rate of Change of Wave Surface Elevation

The rate of change of wave surface elevation is of much importance in ocean engineering,es-pecially for the determination of the limitation of wave breaking.This paper gives a kind of joint distribu-tion of wave periods and the rate of change of wave surface elevation by means of calculation of the two-or-der to four-order moment of the frequency spectrum based on the linear wave theory.For the first time,the distribution density function of wave periods determined by peaks is provided,and the conclusion isdrawn that the rate of change of wave surface elevation obeys the Rayleigh distribution.     

Study of the ice conditions in the Gulf of Ob

The results of theoretical studies of fracture lines in the ice floes of the Gulf of Ob as a function of the coefficient of internal sliding are presented in this paper. An estimate of the fractal dimensions of the emerging topological structures and the results of the calculation of stresses in the ice cover of the Gulf of Ob are presented as functions of different directions of external forcing caused by the joint action of winds and currents on the ice. The geographical locations of the zones of possible loads are shown, together with the estimates of the hummock sizes in the zones of the maximal compression of the ice floes in the Gulf of Ob.     

Numerical analysis of the propagation and amplification of tsunami waves on the northwest shelf of the Black Sea

We perform the numerical analysis of the process of propagation of long waves in the northwest part of the Black Sea and consider ten possible zones of the seismic generation of tsunamis. The numerical analysis is performed on a grid with steps of 500 m. It is shown that the location of the tsunami source significantly affects the distribution of the heights of waves along the coast. As a rule, the most intense waves are formed in the closest part of the coast. The earthquakes in the South-Coast seismic zone do not lead to the formation of tsunamis in the west part of the sea. Only strong earthquakes in the northwest part of the sea can be responsible for noticeable oscillations of the Black-Sea level. The period of tsunamis near Odessa is close to 1 h and depends on the magnitude of the earthquake. In the region of Sevastopol, this period is 2--3 times smaller. In the major part of the coastal points, the extreme elevations and lowerings of the sea level do not exceed (in modulus) the initial displacements of the sea surface at the source of tsunamis. An intensification of waves emitted from the zones of generation located in the deeper part of the investigated region was observed for some parts of the Romanian coast and the west coast of Crimea. As the magnitude of the earthquake increases, the intensification of waves near the coast becomes more pronounced.     

Investigation of Transformations of the Local Regions of Pollution in the Northwest Part of the Black Sea Caused by the Motion of a Cyclone

By the method of mathematical simulation, we study the evolution of local discharges of pollutants on the northwest shelf of the Black Sea induced by the motion of a cyclone. We use the nonlinear equations of motion of a homogeneous viscous fluid in the hydrostatic approximation and the equation of turbulent diffusion. A cyclonic formation is represented by a moving axisymmetric area of low pressures. The discharges of pollutants are caused by the action of instantaneous sources located on the sea surface. We perform the analysis of dependences of the paths of motion of polluted regions, the periods of their dissipation, and the depths of penetration of pollutants on the bottom topography and the intensity of diffusion processes. __________ Translated from Morskoi Gidrofizicheskii Zhurnal, No. 6, pp. 17–27, November–December, 2005.     

Agent-Based Marine-Ecosystems Modeling

We propose a new information technology aimed at modeling of biochemical processes in marine ecosystems and based on the use of logical operators of control (intelligent agents) in the dynamic equations of the models. We develop a conceptual model of an ecosystem reflecting the interaction of 17 biochemical processes and 5 external factors. The equations of the model are obtained by the method of adaptive balance of causes (ABC method), which enables one to simulate complex scenarios of the processes running in the investigated systems and guarantees the possibility of robust calculations. Some examples of the behavior of ecosystems under the conditions of deficiency of oxygen caused by the action of natural and anthropogenic factors are presented. As a result, it is possible to make a conclusion that the combined application of the ABC-equations and intelligent agents of control in models of marine ecosystems is quite promising.
