Перевод статьи "Assessment of the planet tectonic stability in connection of the radon volumetric activity variations in the surface atmosphere".
В работе представлены статистические данные вариаций объемной активности радона в приземной атмосфере и суммарного количества землетрясений разной магнитуды на годовом интервале. На основе полученных рез...
Statistical data on variations of the radon volumetric activity in the surface atmosphere and the total number of earthquakes of different magnitudes over an annual interval have presented. Based on the obtained results, a conclusion has made about an indicator of the planet tectonic stability.
One of the important unsolved problems related to the evolution of living conditions on Earth is the mechanism of the rapid transformation of the Black Sea from a shallow lake-type sea into a deep-water basin, the earth's crust in the central part of which does not have a granite layer. There is no explanation as to how “granite-free depressions” w...
Доклад об абразионных процессах на побережье древних трансгрессивных морей Паратетис и Каспийских.
В статье описаны процессы, протекавшие в мантии Земли в условиях возникновения отрицательного давления. В магме под Средиземным, Черным и некоторыми другими морями такое давление возникало в условиях вздымания плиты в период мессинского соляного кризиса (во время высыхания моря). В магме образовывались пустоты, которые способствовали разрушению гра...

The article presents a solution to an equation describing the processes of filling depressions with water in the relief of formation and ancient transgressive seas. A model has been developed for the course of the sea level during the creation of the sea and during its drying up. The graphs of the course of the level of the Sarmatian and early Khva...
The basis of the theory of evolution of transgressive the Akchagyl Sea is based on the hypothesis that the transgression was created by water coming from an as yet unidentified ocean. This causes some doubt due to the fact that in the Akchagyl time the ocean level was about 100 m below sea level. The article calculates changes in salinity in the se...
The article calculates the freshwater balance of the ancient Black and Caspian seas and estimates the volume of water flowing from the Black Sea to the Mediterranean during the melting of glaciers. It is shown that during this period up to 855 km3/year of freshwater is discharged into the Mediterranean Sea, which is involved in the formation of sea...
In the article the ancient geological processes of transporting a huge volume of water (up to 2500 km3/year), whereby the Paratethys Sea and the Manych, Bosporus and Dardanelles straits was formed, are regarded as deterministic physical processes. In our opinion, these processes can be studied by mathematical modeling. 5 million years ago, similar...
The mechanism of transport and accumulation of anthropogenic radionuclides (137Cs) in the Black Sea is analyzed on the basis of data obtained within the framework of the IAEA international project RER/2/003. The features of the sedimentation of the contaminated suspended matter to the shelf, the continental slope and the abyssal plain. The estimati...
A mathematical model describing the change in the Black Sea level depending on the Aegean Sea level changes is presented in the article. Calculations have shown that the level of the Black Sea has been repeating the course of the Aegean Sea level for the last at least 6,000 years. And the level of the Black Sea above the Aegean Sea level in the ten...
Vertical movement of Earth crust can modify the shape of the eustatic sea level curves. A method allows calculation of the eustatic sea level course using the known local curves. We were able to divide a number of local curves of the Mediterranean Sea to the eustatic and tectonic components. The data about dynamics of the vertical crustal movements...
This paper aims to develop a theoretical hydromechanical model designed to explain slow motion of thin sediment suspension layer over the Black Sea abyssal plain. The suspension flows are regarded as a new lateral deep sea sediment transport mechanism differing from turbidity currents and other gravity flows in minor mass scale and velocity. The su...

The origin of the bottom counterflow in Bosphorus Strait during the early Holocene, its temporal development and the Black Sea filling by the Mediterranean salt water is discussed in this paper. At 10 ka, the depth of the strait was 10 m, the velocity of accumulation body growth in the southern part of the strait was 3 mm/year, and the velocity of...
A possible mechanism leading to the transformation of the Paratethys seas (i.e., the Sarmatian Sea-Lake, Meotian Sea, Pontian Sea-Lake, etc.) is here proposed. The time period from the formation of the closed Sarmatian Sea-Lake to the present is also considered. It will be shown that the main reason for the collapse of the Sarmatian Sea-Lake into t...
A mathematical model of the Black Sea level change for the last 20,000 years is presented in this paper, based on the equations of viscous incompressible fluid motion according to Navier–Stokes, Sen-Venans, and the equation of water balance in the sea. The solution of the differential equations shows that the Black Sea level has been generally risi...
The climate change on the Earth is periodical and the global warming replaces glacial periods and vice versa. For about last 20 thousand years, the process of global warming has been continuing on our planet. As a result, the rise of the World Ocean level and deglaciation of ice which was formed during the last glacial period have been occurring fo...

One of the fundamental issues of the paleooceanology is studying variations in the level of the World Ocean and those of marginal, poorly connected seas (for instance, the Black Sea) for the past 20 000 years since the last peak of the continental glaciation in the Northern Hemisphere. This issue is still far from resolved, because researchers have...
One of the global processes on the planet in the Late Pleistocene-Holocene was transgression in the World Ocean level and initiated by it changes in the levels of inland seas. The study of this process in the Black Sea was not allowed to set a timetable for the changes of its level during the time. For more than 50 years of research, scientists sug...
For the description of the Black Sea level fluctuations during the latest 20 ky, i.e. during the period of global warming, glacier melting an d formation of modern climate a mathematical model was proposed in the form of nonlinear differential first-order equation. It was found from the equation of water balance in sea and known solutions of the Na...

Современные исследования показали, что Черноморский глубоководный бассейн заполнен мощным комплексом терригенного материала, сбрасываемого реками в береговую зону моря. Слои осадочного чехла на протяжении сотен километров залегают полого, прислоняясь к неровностям дна бассейна. Уклон дна уменьшается от берегов к центру моря от 5 • 102 до 3 • 104 [1...
A characteristic peculiarity of mineral composition of bottom sediments in the Sea of Azov is their high carbonate content. The sea has features characteristic to weakly mineralized basins both of arid and humid zones. Accumulation of calcium carbonate in bottom sediments of the Sea of Azov is characterized by spatial irregularity of its distributi...
Modern coastal processes at the southeastern coast section of the Sea of Azov are estimated in this work. A mathematical model is proposed. It affords to predict a rate of the coastal abrasion in conditions of the sea level rise. Recommendations are given for the choice of the coast protection methods in this region.
On the Caucasian coast of the Black Sea the first ones negative factors are transformations of the coastal processes resulting in the change of features of the cross profile band the shore outline evolution by means of hydraulic constructions of various economic importance and different direction to the shoreline (longitudinal constructions - moori...
Engineers aspired to reduce negative influence of sea walls on bottom and beach sediment accumulation by building curvilinear walls. But in spite of their diligence, undermining of such constructions took place almost everywhere. The analysis of the efficiency of different walls between the Tuapse and Batumi proves this. Breakwaters became one of a...
Investigations of the ancient and recent continental slope of the Black Sea basin revealed sedimentary layers to be truncated in some sections. The truncation results from erosion action of slumping sediments. The theory of continental slope erosion by moving sediments is developed as a modification of the general theory of erosional processes. The...

Catastrophe theory is used to analyze the stability of seashore development. Criteria for beach degradation under intentional regulation of the inputs of clastic material to the shore zone are found.
Достаточно сложными и еще слабо исследованными являются колебания уровня Черного моря в плейстоцене. Они изучаются в основном по материалам бурения (на суше и на море) и по данным о поднятых террасах [4, 7, 8, 10, 11, 13, 19]. В ряде работ [10, 11, 15, 19] установлена корреляция для отдельных трансгрессивных (и регрессивных) уровней рассматриваемых...
В последние годы все большее внимание исследователей привлекает к себе процесс формирования поверхности шельфа современных морей. Это объясняется следующими обстоятельствами. Во-первых, его изучение открывает перспективы реконструкции геологических, литодинамических и других палеопроцессов, что имеет как научное, так и прикладное значение. Во-вторы...
Theory of optimal control was used for return of an abrasion process in equilibrium stage
For analyzing the process of erosion of seashores in the absence of longshore sediment flow an equation of balance of beach-forming material is proposed. The investigated model can be used in the economic development of the coastal zone in the case when it is planned to carry out coastal protection works by means of forming beach material without p...
