The considerable expenses on exploration work on oil and gas field tracing and prospecting predetermine the necessity of a search of the ways of increase of final effectiveness. One of such directions is the implementation on exploration work practice of a new science intensive computer technologies of integrated interpretation of a complex of geological-geophysical data. As a computing base of such a technology the system of quantitative complex interpretation of geophysical data GCIS (Geophysical Complex Interpretation System) is proposed. The basic principles of construction and operation of the system are reviewed. The specific realization of such concepts as interpretation model, the metalanguage of describing geophysical data, object model of data storage and distributed processing is described.

The paper highlights the results of tectonic structure feature and modern geodynamic investigation on the Chornobyl NPP Exclusion Zone territory and adjacent Korostensky pluton region on the basis of structural and landscape-geoindicational decoding of remote sensing data along with topographical maps. New data completing a geological-geophysical model of the area have been received. It was determined that a network of the modern superficial fractures, lineaments and their zones is traced generally along the discharge axes of stressed-deformational state of rock that induces the local ruptures existence. They indicate the presence of local fracture deformations or elements of various morphogenetic kind of lower range fault structures. Those faults are located in the Earth's crust of the territory and are basic block borders. The analysis of the space allocation of areas with dominating process of tension and contraction deformations at the modern tectogenesis stage allows to outline the long-term grounds for the radioactive waste disposal into the deep geological formations which need to elaboration in detail.

The algorithm for calculating harmonic copmonents of geoid heights and density anomalies in lithosphere, applying spherical functions of external gravity potential, is represented in the paper. Example of deep density structure along well-known seismic geotraverse, which crosses an arc and a trough of the Minor Antillean Islands in the Caribbean Sea.

Phase characteristics and form of elementary signals are changed under the influence of phase velocities absorption and dispersion during seismic waves spread. This abstract proposes correction algorithms of phase specters of signals and seismic tracks to eliminate possible errors. The result of correction is phase deconvolution: phase specters are eliminated and signals are simmetrized. Accordingly, maximal values of transformed signals correspond to the moments of their entries. Phase specters of signals elongated up to continuity or regularized results of Gilbert transformations are applied.

In this article we briefly describe algorithms for linear analytical approximations of geophysical potential fields and geological boundary, as well as we present examples of using approximation approach to resolve real-world problems. The approximation functions are sourcewise representable and trigonometric functions, wavelets. The following problems are considered: the 3D-interpolation of gravity field value; transform (including the recalculation of the field onto horizontal plane and the construction of geologically orientated regional background); the estimation of petroleum reserves; calculating of gravity terrain corrections; the decimation of digital elevation model grid.

The results of geoelectric and seismic-acoustic investigations on the two ravine area in Odessa region are given. The depths of lying of main water horizon and separate water lenses are determined. The zones of vertical migration of underground water are installed. The organization of the dumps in investigation regions in not possible with ecological standpoint.

During the seasonal works of the 9-th Ukrainian Antarctic Expedition the thickness of the ice cap situated near the Academic Vernadsky station on the Galindez Island was measured. This problem was solved by the vertical electric-resonance sounding method that is widely used in solving different ecological, geologic-geophysical and geologic-engineering problems. Results of these works were used to set up: a sketch-map and 3-D diagram of the ice cap thickness on Galindez Island; vertical sections of the glacier mass along five profiles; sketch-map and 3-D diagrams of the Galindez Island surface both with the ice cap and without it. Researches the carried out show that the vertical electric-resonance sounding method can be effectively used for the West Antarctica studying of the ice cap structure.

The application of the method of the acoustic facts' inversion is considered for the estimation of the structure of the empty space of the complicated carbonic and terigenic rock collectors of the coal-mining deposits of the Berezovska and Narizshnyanska areas of the Dnipro-Donetsk depression.

The algorithm for the paleogeographic and sedimentological analysis of the oil- and gas-bearing objects in the Dnieper-Donets depression on the base of complex interpretation of geological, geophysical and well-logging data is given. The use of modern computer technologies in solving these problems allows creating the most optimal and trustworthy model for the geologic medium.

This article is devoted to the GIS technology applied for risks assessment, which have different spatial distribution and stable spatial phenomena parameters. Anomalous technogenic loads on ecosystems within Ukrainian territories are the basis for regional technogenic changes of environmental and conditions for life activity. Geoinformation technologies give the possibility for objective evaluation of the natural-technogenic system risk assessment, which are of different ecological character.

Seismic time sections show depositional processes following the relevant geological cross-sections. Usage of standard time sections is mostly related to markers, which allows the general study of the depositional sequences formed during the depositional environment stabilization period. Using high resolution time sections ensures more detailed depositional environment study throughout the whole thickness of the depositional basin including both transgressive and regressive (overlap and off-lap) series.

In this article on the base of the long experience for carrying out the expedition monitoring tasks in marine ecosystems, being in conditions of the various antropogene stress levels the potentialities and perspectives of the ecosystem state exploration near the location of the ukrainian antarctic "Academic Vernadskiy" station with a help of monitoring control and modeling calculation are under consideration.

The author concentrates on the role of the category of Time in modern paradigm of Society Geography. The rise and strain of the global ecological problem is supposed to be caused by the pace in the development of Nature and Society. Such traces of Time are sure to take place in Geographical Space. Their detecting and compressing a will prevent the reduction of Geographical Space and thus the rise of global ecological problems. A new paradigm, in view will help to structure of complex spatial socio-nature systems accurately as objects of geoinformation modeling.

A history of heliomagnetism as a science and a study of its interconnection with a solar electromagnetism is under analysis. Means and methodology of obtaining new knowledge of interconnection between the earth and the solar events in process are interpreted as well as the first results of investigations of a solar-heliospheric observatory (SOHO).

The paper is the tenth one in the series of publications, that are dedicated to fundamental problems of geoinformatics - subject of scientific research, main aims of the new science, methods to solve its specific tasks and so on. In the tenth paper the problem of using the Principle of Simplicity in geosciences and formation of the new disciple "geosimplics". The concept of "the simple and beautiful absolute planetary time-scale" as a main tool of understanding the geologic history is discussed.

The paper is the ninth one is the series of publications, that are dedicated to fundamental problems of geoinformatics - subject of scientific research, main aims of the new science, methods to solve its specific tasks and so on. In the ninth paper the fundamental problem of geocategorology is discussed: is the geologic time continual or discrete? This problem is connected with other very important problem: it can be proposed an natural (non-conventional, non-formal, non-artificial) geochronological and geostratigraphical classification? Such a united hierarchical system of natural geochronological classification of the Phanerozoic history up to units that are 343 thousand long is build. The application of the proposed natural classification in research work do change radically geology as a science. On the base of the natural geochronological classification the geodynamical methods of superprecise evaluation of absolute age of sediments are developed.

The paper is the fifth one in the series of publications, that are dedicated to fundamental problems of geoinformatics - subject of scientific research, main aims of the new science, methods to solve its specific tasks, and so on. The main topic of the fifth paper is the role of geoinformatics in the intellectual movement that was called "Vernadskian revolution". Same problems of the new scientific disciples as biospherelogy and nousspherelogy are discussed, in particular the problem of the "Vernadsky's biogeochemical paradox".

The paper is the seventh one in the series of publications that are dedicated to fundamental problems of geoinformatics - subject of scientific research, main objectives of the new science, methods to solve its specific tasks and so on. In the seventh paper the problems of geohermeneutics are discussed. In particular the causal models for galactical geology as examples of explanation in geosciences are given.

The paper is the eighth one in the series of publications, that are dedicated to fundamental problems of geoinformatics - subject of scientific research, main aims of the new science, methods to solve its specific tasks and so on. In the eighth paper the problem of fundamental hermeneutic situation in geology and in science in general is discussed: how to read ("to decipher", "to decode") the "stone chronicle" of the Earth's crust. To solve the problem a new conceptual picture of the Universe and a new strategy of cognition are proposed. All that permits to reequip radically the geosciences and to speak about "new geology". A new conception of geologic time scale is considered. The detail symmetric model of phanerozoic history of the Earth is examined. The possibilities of the "Lyell's reverse principle of actuallism" are demonstrated.
