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.

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.

The study of vortex and wave flows is one of the traditional problems of fluid mechanics, the practical importance of which has grown significantly in recent years. Consideration of the processes of substance transfer in such complex systems as natural water bodies is fraught with many difficulties of a methodological and fundamental nature: the extreme complexity of conducting a full-scale experiment, the complexity and variability of hydrophysical fields of the ocean and hydrometeorological conditions during research, and also, in some cases, the complexity and the variability of the properties of the transferred substance. In this connection, it is of particular interest to study the transfer of markers in stationary vortex and wave flows, which can form in laboratory facilities with constant external conditions. In this case, it is possible to avoid problems associated with the spatial and temporal variability of natural sources of vortex formations and directly trace the dependence of the characteristic flow parameters or the characteristics of the movement of solid or other objects placed during. This book presents the results of experimental and theoretical studies of the dynamics and structure of multiphase vortex flows and the nature of the transfer of three types of markers: solid-state (ice, plastic), immiscible with water (oil, oil, diesel) and soluble (aniline dyes, uranyl). The results will be important, first of all, for a better understanding of the behavior of various impurities in the circulation flows and more accurate prediction of their distribution in natural conditions (in a stratified hydrosphere and atmosphere).

This book is devoted to the most important and urgent problems that arise during the development of the coasts of the cold seas. The most important result of the work is the creation of an engineering-oriented concept of morpholithodynamics of the shores of the Arctic and subarctic seas and the forecast of coastal development in conditions of rapid natural and anthropogenic changes. The established patterns of development of the coastal zone in the coordinate system of the concept of contact zones of different types of sea, seas and ocean open up new opportunities for improving the theory and methodology of cognition of the natural environment and the relief of the coastal zone as the basis for the life of society and ensuring sustainable development in these regions. In addition to theoretical significance, the established patterns have a pronounced applied aspect—solving infrastructure safety problems, coastal protection and marine logistics, risk assessment and planning of economic activities on the coast, creation of natural and economic accounting systems. Using the example of the Far Eastern region of Russia, the issues of anthropogenic transformation of coastal morpholithosystems are considered. The results of theoretical constructions and modeling of morpholithodynamic processes are used to determine the quantitative parameters of the carbon cycle of biomorpholithosystems of the coastal zone and adjacent marine areas, in conditions of accelerating evolutionary changes and increasing anthropogenic load. This makes it possible to switch to controlled climatic activities for the absorption of carbon dioxide from the atmosphere, accumulation, transformation and long-term burial of autochthonous and allochthonous organic carbon using nature-like technologies on created coastal marine wetlands (carbon farms). The book is addressed to specialists in the development and implementation of projects related to investment, construction, natural and climatic activities, modernization of housing, communal, industrial, transport, social, energy and other infrastructure in coastal areas in high latitudes. It can be useful for students and postgraduates studying in the specialties of geomorphological engineering, hydrotechnical and climatic directions.
