The book considers the riverine paleo structures of the coastal marine zone from the point of view of marine bottom seismic acoustics. The authors describe the mechanisms of the origin and features of riverine paleo structures in the coastal marine area. The methods applied for this kind of research have been developed and explained comprehensively, including geomorphology and interpretation of seismic acoustic facies. Besides, the authors also propose a classification of morphological features, signs and technology of recognition, as well as methods for mapping of coastal river facies supported by an extensive list of literary sources is given. The book will be of interest to marine geophysicists, marine geologists, and those interested in new methods to approach marine problems worldwide.

The book deals with some issues of paleo-geodynamics of the Eurasian floor of the Arctic Ocean. A comprehensive geological and geophysical analysis of information on the anomalous magnetic field in the Eurasian Basin was carried out using modeling of the inversion magnetically active layer of the oceanic crust. As a result of this analysis, the identification and spatial position of linear paleo-magnetic anomalies were refined, which made it possible to significantly update the geochronology of the bottom of the Eurasian Basin and identify a number of stages in its evolution. On this basis, the features and stages of the kinematics of the development of the bottom of the Eurasian Basin in the past were revealed. At the first Cretaceous–Paleogene stage, prior to the formation of the A26 paleo-anomaly on the Eurasian margin, extension processes developed significantly and turned into rifting. In the process of rifting, weakened zones and related fractures were formed, along which the Siberian continental margin began to be torn off about 60 Ma ago with the formation of the Lomonosov Ridge. At the second stage of evolution, rifting turned into spreading, and the growth rate of the new oceanic crust in the A26–A24 paleo-anomaly interval (59–53 Ma ago) was more than 2.5 cm/yr. At the same time, the northern flank of the Mid-Arctic Ridge grew more intensively than the southern one. The third stage was characterized by a further progressive slowdown in the process of bottom spreading, the minimum of which, with spreading rates of about 1 cm/year, fell on the formation of paleo-anomalies A13-A6 (30-20 million years ago). The fourth stage of growth of the new oceanic crust began later than the time of the A6 paleo-anomaly and is characterized by some intensification of growth at rates up to 1.2 cm/yr. The average rate of bottom growth over an interval of almost 60 Ma turned out to be close to 1.3 cm/yr, which makes it possible to classify the Mid-Arctic Ridge as a slow-growing one. On this basis, kinematic models of the development of bottom configurations were developed with the determination of the Euler poles, rotation angles, asymmetries, axes of spallation and paleo-bathymetry for the Eurasian Basin, the Polar part of the Lomonosov Ridge, the splitting of the Arlis Spura from the Lomonosov Ridge, the development of the Gakkel Ridge and the development of the Greenland region of the bottom.

The book presents short papers of participants of the 10th International Scientific Conference and School for Young Scientists «Physical and Mathematical Modeling of Earth and Environment Processes. The book includes theoretical and experimental studies of processes in the atmosphere, oceans, the lithosphere and their interaction; environmental issues; problems of human impact on the environment; methods of geophysical research. Research of the dynamic of natural systems - geosphere, hydrosphere, atmosphere and their interactions, the human contribution to naturally occurring processes are among the most urgent and practically important scientific problems. Intensive development of research in these areas is due to several factors. The widespread introduction of computer technology has allowed beginning calculation of complex phenomena, previously unavailable for analysis. Creation and improvement of a new generation of geophysical instruments, remote observing systems based on the ship, aircraft, and satellite allowed us to obtain a large amount of data to objectively reflect the picture of the processes. The articles included in these book reflect also an important role of the laboratory modeling in searching of processes in geo-environments and testing of new developed physical and mathematical models. Development of measurement, optic information and other techniques provide new opportunities to perform controllable and reproducible laboratory data for generations of new ideas and concepts. Systematic stream of high resolution laboratory data stimulates development of analytical and numerical models of the dynamical processes in three nature environments. A special focus is given to the extraction of hydrocarbon resources, including from unconventional sources. An alternative to the use of hydrocarbons as a main source of energy on the Planet in the coming decades is unlikely to be found. At the same time, the resource base of hydrocarbons is quickly depleted, in particularly, large and accessible oil and gas fields. The shale oil and gas, Arctic hydrocarbon stocks, gas hydrates, coal bed methane, oil and gas from deep horizons can become new sources.

We are poised to embark on a new era of discovery in the study of geomorphology. The discipline has a long and illustrious history, but in recent years an entirely new way of studying landscapes and seascapes has been developed. It involves the use of 3D seismic data. Just as CAT scans allow medical staff to view our anatomy in 3D, seismic data now allows Earth scientists to do what the early geomorphologists could only dream of - view tens and hundreds of square kilometres of the Earth's subsurface in 3D and therefore see for the first time how landscapes have evolved through time. This volume demonstrates how Earth scientists are starting to use this relatively new tool to study the dynamic evolution of a range of sedimentary environments.
