A method of estimation of the results of reconstruction of the trajectories of drifting buoys

A method for the estimation of the results of reconstruction of the trajectories of drifting buoys is proposed. It is based on the comparison of the estimates of power spectral densities for the components of current velocity computed according to three data sets: the data set of the coordinates of a drifting buoy with a built-in GPS receiver, the data set of coordinates formed on the basis of the first set but with data missing and observational errors corresponding to the actual trajectory measurements by the Argos satellite location and data collection system by the Doppler method, and the data set of coordinates obtained as a result of interpolation of the second set. As an example, we consider the procedure of realization of the proposed method and demonstrate the efficiency of its application for the improvement of the reliability of reconstruction of the trajectories of drifting buoys.     

Estimates of fishery potentials of the EEZ of India

An attempt has been made to estimate the fishery potentials of the EEZ of India on the basis of data on primary and secondary production. The total column primary production and zooplankton production have been calculated to be 265·9 and 9 million tonnes of carbon per year, respectively. From these values the fishery potential has been estimated as 2·5 million tonnes per year. To this, if we add the estimated demersal fish catch, being 1·2 million tonnes per year, the total potential yield comes to 3·7 million tonnes per year. Since the present average total catch is about 1·6 million tonnes in a year, the fish catch could be doubled.     

韩国的海岸带综合管理

1992年，联合国21世纪议程提出了综合管理的概念，并认为它是海岸管理的最重要目标，而海岸管理的目的就是改进业已存在的管理实践的效率和效果。在21世纪议程的实施过程中，沿海国家面临着巨大的困难，即：为了使综合管理在实践中具有可操作性而建立适合的政府机构。韩国正是在国家范围和次一级区域进行这项工作的实验场所。这项工作的最重要成就是在1996年成立了具有综合协调各涉海部门职能的韩国海洋事务与渔业部（MOMAF）。这篇文章的内容主要来自于这些观察，即韩国政府为建立海岸带综合机制而进行了各种努力，特别是1992年联合国环发大会召开后到1997年初海洋事务与渔业部成立了海岸带管理处这段时间里开展的各种工作，文章重点在于评价在建立海岸带综合机制的过程中综合的概念是如何被应用并被挑战的。文章提出了在东亚地区沿海国家开展合作的可能区域的建议。

A model of the dynamics of the ecosystem of the Sea of Azov

We use many-year archival observations of hydrologic and hydrobiologic state of the Sea of Azov for the identification of the structure of a model of its ecosystem. The ecosystem model, supplemented with expert estimates of bioresource consumption (fish reserve), contamination level, and possible ecologic fines for violation of the sea natural state, is formalized by the method of system dynamics. Hereat, the major part of influence functions is found in terms of observational data with application of self-organization algorithms. We also present the results of simulated experiments with the model of the ecosystem, which enable us to analyse scenarios of its behaviour under the influence of various external factors (wind, river discharge, water exchange with the Black Sea, etc.).

Analysis of photographic images of the structure of the surface of the sea near a speck of light

Values of root mean square slope ₀ and its variations -₀ are estimated using the brightness field of an image of the surface of the sea near a speck of light. When ₀ and -₀ are defined it is highly important to take into account direct as well as dissipated solar radiation.The space-time analysis of the structure of the image brightness field is performed. This gives an opportunity to estimate dispersion relationship and the running effect of a brightness contrast packet. Comparison of the parameters obtained with the theoretical dispersion ratio of internal waves (IW) allows one to make a conclusion that IW surface manifestations are recorded in a frame.UDK 551.463.5     

Hierarchy of the models of classical mechanics of inhomogeneous fluids

The methods of perturbation theory and integral representations are used to analyze the general properties of a system of equations of the mechanics of inhomogeneous fluids including the equations of momentum, mass, and temperature transfer. We also consider various submodels of this system, including the reduced systems in which some kinetic coefficients are equal to zero and degenerate systems in which the variations of density or some other variables are neglected. We analyze both regularly perturbed and singularly perturbed solutions of the system. In the case of reduction or degeneration of solutions, the order of the system decreases. In this case, regularly perturbed solutions are preserved (with certain modifications) but the number of singularly perturbed components participating in the formation of the boundary layers on contact surfaces and their analogs in the bulk of the fluid, i.e., the elongated high-gradient interlayers, decreases. The interaction between all components of the currents is nonlinear, despite the fact that their characteristic scales are different.
