This book is the result of collaboration within the framework of the Third International Scientific School for Young Scientists held at the Ishlinskii Institute for Problems in Mechanics of Russian Academy of Sciences, 2017, November. The papers included describe studies on the dynamics of natural system - geosphere, hydrosphere, atmosphere-and their interactions, the human contribution to naturally occurring processes, laboratory modeling of earth and environment processes, and testing of new developed physical and mathematical models. The book particularly focuses on modeling in the field of oil and gas production as well as new alternative energy sources.

This book provides information on the causes, consequences, and possible solutions to modern environmental problems associated with ocean pollution with a particular focus on the Back Sea. The oceans are a vast but fragile complex. In recent decades, it has become especially manifest when ocean pollution has reached an unparalleled situation. Meanwhile, not only the well-being of ecosystems depends on the state of ocean waters, but human civilization largely depends on the oceans as a consequence of environmental dependence. This book examines the consequences of pollutants such as oil and hydrocarbon products (including plastics and microplastics), water acidification, sewage, wastewaters discharge into the ocean, thermal pollution, nuclear pollution, and biological pollution. Beyond the types of pollutants and their consequences, this book outlines the state of the art of the legal situation internationally regarding ocean pollution. The authors also show the current pollution of the inland seas, taking as an example of the Black Sea (anthropogenic and natural sources of pollution, its shelf, and shallow waters as well as international legislation). A part of the book analyzes the main types of environmental monitoring of the oceans and their role in solving ocean pollution problems with a particular interest in the Black Sea. The book is of interest to specialists in ocean pollution, ecologists, oceanologists, students, and graduate students studying oceanography, marine ecology, current methods of environmental monitoring, and legal problems related to the oceans and seas pollution, as well as to anyone interested in modern problems of the oceans.

This book describes a comprehensive selection of ocean processes such as wave phenomena (surface, internal gravitational, and acoustic waves), the influence of surfactants and pollutants on the aquatic environment's dynamics, the models of the stratified natural environment, convective phenomena in the ocean, and the interaction of wave and convective processes. Finally, this book dedicates the last section to unsolved problems in the physics of anomalous waves. Most of the chapters present the most hegemonic theories but also they introduce the revulsive ideas based on alternative approaches. The underlying mathematical models are scientifically justified both at the physical and formal mathematical levels. In all known limiting cases lead to well-known classical results. They are in good agreement with experimental data. Several sections show the application of developed approaches to the description of natural phenomena. The book is of interest to specialists working in the field of ocean physics, as well as undergraduate and graduate students specializing in marine physics and oceanography.

This book considers the formation of the signal reflected from the sea surface when sensing in the radio and optical range. Currently, remote sensing from space is the main source of information about the processes taking place in the atmosphere and ocean. The correct interpretation of remote sensing data requires detailed information about the rough surface that forms the reflected signal. The first three chapters describe the statistical and spatial-temporal characteristics of the sea surface, focusing on the effects associated with the nonlinearity of sea surface waves. The analysis makes extensive use of data obtained by the authors on a stationary oceanographic platform located on the Black sea. In the next seven chapters, the authors analyze how the nonlinearity of waves affects the formation of a signal reflected from the sea surface.This book is geared for advanced level research in the general subject area of remote sensing and modeling as they apply to the coastal marine environment. It is of value to scientists and engineers involved in the development of methods and instruments of remote sensing, analysis and interpretation of data. It is useful for students who have decided to devote themselves to the study of the oceans.

This book entitled "Physical and Mathematical Modeling of Earth and Environment Processes" is the result of a collaborative work after the 4th international scientific youth forum held at the IPMech RAS on November 1-3, 2018. 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. A special focus is given to the extraction of hydrocarbon resources, including unconventional sources. This book also focuses on new approaches to the development of hydrocarbon fields, very important in today's geopolitical conditions. The book presents new results of the experimental and theoretical modeling of deformation, fracture and filtration processes in the rocks in connection with issues of creating scientific fundamentals for new hydrocarbon production technologies.

This book presents a comprehensive overview of hydroacoustics and describes the physical basis of acoustic processes observed in the sea. In addition, it discusses the basic concepts and provides simplified models of sound propagation and acoustic phenomena at the boundary between environments. Lastly, the book examines in detail a number of applications of ocean acoustics and methods. The ocean is the last reserve of natural resources. It is also an essential element in the biosphere, ensuring the latter's balance, and plays a pivotal role in the Earth's climate system and global warming. Consequently, studying the ocean is one of humankind's most critical scientific tasks, but penetrating its mysteries is no mean feat. Acoustics (hydroacoustics) is one of the most powerful tools for examining the water layer and beyond, since sound waves are the only type of radiation that can propagate over distances of hundreds and even thousands of kilometers in the ocean. This unique resource appeals to specialists working in the fields of ocean and atmosphere physics, students and postgraduate students studying sea physics and oceanology, and anyone who is interested in the problems the ocean is currently facing.
