The theory of waves is generalized on cases of strongly nonlinear waves, multivalued waves, and particle-waves. The appearance of these waves in various continuous media and physical fields is explained by resonances and nonlinearity effects. Extreme waves emerging in different artificial and natural systems from atom scale to the Universe are explored. Vast amounts of experimental data and comparisons of them with the results of the developed theory are presented. The book was written for graduate students as well as for researchers and engineers in the fields of geophysics, nonlinear wave studies, cosmology, physical oceanography, and ocean and coastal engineering. It is designed as a professional reference for those working in the wave analysis and modeling fields.
Modeling of Extreme Waves in Technology and Nature is a two-volume set, comprising Evolution of Extreme Waves and Resonances (Volume I) and Extreme Waves and Shock-Excited Processes in Structures and Space Objects (Volume II). The theory of waves is generalized on cases of extreme waves. The formation and propagation of extreme waves of various physical and mechanical nature (surface, elastoplastic, fracture, thermal, evaporation) in liquid and solid media, and in structural elements contacting with bubbly and cryogenic liquids are considered analytically and numerically. The occurrence of tsunamis, giant ocean waves, turbulence, and different particle-waves is described as resonant natural phenomena. Nonstationary and periodic waves are considered using models of continuum. The change in the state of matter is taken into account using wide-range determining equations. The desire for the simplest and at the same time general description of extreme wave phenomena that takes the reader to the latest achievements of science is the main thing that characterizes this book and is revolutionary for wave theory. A description of a huge number of observations, experimental data, and calculations is also given.
The sea has been the site of radical changes in human lives and national histories. It has been an agent of colonial oppression but also of indigenous resistance, a site of loss, dispersal and enforced migration but also of new forms of solidarity and affective kinship. "Sea Changes "re-evaluates the view that history happens mainly on dry land and makes the case for a creative reinterpretation of the role of the sea: not merely as a passage from one country to the next, but a historical site deserving close study.
Highlighting twenty years of U.S. scientific research conducted since the International Geophysical Year (IGY) of 1957-58, this volume marks a turning point in the history of polar investigations and provides a lucid summary of the contributions of many distinguished scientists. The authors provide an overview of major polar research programs, past and present; explore concepts derived, from highly interrelated aspects of physical and life sciences; and seek to offer a glimpse of future polar science and polar development. The introduction briefly describes major physical, biological, and interdisciplinary research programs, as well as the magnitude, extent, and international character of contemporary polar science. Twenty years of polar biological investigations are then reviewed, and subsequent chapters address principles and advances in meteorology, physical oceanography, glaciology, and the geological evidence that hears on the origin of Antarctica. These physical sciences delineate a matrix for the polar biospheres and provide a background for understanding the major categories of structure and dynamic functioning of the marine ecosystem, polar marine mammals, adaptational physiology, and terrestrial biotic adaptations.
During the recent decades, social, political and academic endeavours have been made to improve environmental quality and reduce pollution. In particular, the ocean, sea and coastal areas show varying degrees of impact from the multiple human activities carried out in the terrestrial as well as in the aquatic environment. Ecology is a science which studies the relationship between organisms and the surrounding environment and in the modern era, the marine world is getting increasing attention. For centuries it has been the final reservoir of human garbage; later it became an oil farm with a concomitant increase of coastal population growth and unplanned growth of the fishing industry and the increasing use of sea routes for cargo transport and recreational uses (cruises). All this led to rising contamination with negative effects on biota and even human health. It is then imperative to know the current situation of the world's oceans: that is the main purpose of this book, to document at a glance the latest research in the field of ocean pollution.
Did you know that the Grand Bank earthquake of 1929 triggered a huge submarine mass movement which broke submarine cables over a distance of up to 1000 km from its source and generated a tsunami which devastated a small village in Newfoundland killing 27 people? The same happened in Papua New Guinea in 1998 with more than 2000 casualties. Submarine mass movements of various sizes and styles are shaping the sea floor and are of concern for many facets of human activities both onshore and offshore. These include the development of natural resources, energy and communication transport, coastal infrastructures and communities. This book provides a world-wide perspective of submarine mass movements and their consequences. This has been made possible by assembling excellent contributions from active researchers, groups, or institutions, thus providing full coverage of the many scientific and engineering aspects of this type of marine and coastal geo-hazard. It covers fundamental as well as site specific studies from many areas including the Atlantic and Pacific oceans, inner seas like the Mediterranean Sea, and fjords using the most recent technologies from multibeam sonar imaging techniques, 3D seismic analysis, slope stability analysis, to debris flow and tsunami modeling. Audience: This book is of interest to any researcher in the field of marine and coastal geo-hazards. It will be useful for planners, scientists and engineers involved in the development of offshore and near-shore resources and also to those in charge of the management and mitigation of coastal hazards. For graduate students, this book provides an up-to-date vision of the process of submarine mass movements and theirconsequences from both a scientific and an engineering standpoint, and it includes a unique collection of the existing literature on marine geo-hazards. CD-Rom included
This is more than the story of a voyage. It is the story of Bernard and Francoise MoitessierAs honeymoon voyage from Europe to the islands of the Pacific and back by way of Cape Horn. Setting out from Tahiti, they took the alogical routeA back because it was the fastest, taking them through the Roaring Forties, through the high attitudes of relentless gale-force winds, and through iceberg territory. Their survival was due to great seamanship, careful preparation, and perhaps also their sense of harmony with JOSHUA and the sea. It is the story of JOSHUA (named for their sailing hero, Joshua Slocum), the dreamboat that became a reality, of how Moitessier recovered from the disaster of losing his previous boat u which he built himself u to pursue his great love, sailing the worldAs oceans. It is also a marinerAs guide to the pleasures and perils of sailing the Trade Winds, the archipelagos of the Pacific, and the Cape Horn route including preparation suggestions and the sailing survival knowledge that made the MoitessierAs voyage successful and joyous. Bernard Moitessier was one of the worldAs great small-boat sailors, and he displays his skills and knowledge in this book. He writes
Cohesive sediment, or mud, is encountered in most water bodies throughout the world. Often mud is a valuable resource, synonymous with fertile land, enriching the natural environment and used as an important building material. Yet mud also hinders navigation and consequently, dredging operations have been carried out since ancient times to safeguard navigation. Unfortunately, many mud deposits are now contaminated, endangering the eco-system and increasing the costs of dredging operations. The transport and fate of mud in the environment are still poorly understood and the need for basic research remains. This text contains the proceedings of the INTERCOH-2000 conference on progress in cohesive sediment research. It was the sixth in a series of conferences initially started by Professor Ashish Mehta in 1984 as a "Workshop on Cohesive Sediment Dynamics with Special Reference to the Processes in Estuaries". During these conferences the character of the first workshop has always been maintained, that is, small scale and dedicated to the physical and engineering aspects of cohesive sediments, without parallel sessions, but with ample time for discussions during and after the presentations, and followed by a book of proceedings containing thoroughly reviewed papers. INTERCOH-2000 was integrated with the final workshop of the COSINUS project. This project was carried out as a part of the European MAST-3 programme, and almost all European cohesive sediment workers were involved. INTERCOH-2000 focused on the behaviour and modelling of concentrated benthic suspensions, i.e. high-concentrated near-bed suspensions of cohesive sediment. Special attention was paid to: sediment - turbulence interaction; flocculation and settling velocity; high-concentrated mud suspensions; processes in the bed - consolidation; processes on the bed - erosion; field observations on mud dynamics; instrumentation; and numerical modelling.
This new edition - now with Nancy Jackson as a co-author - continues the themes of the first edition: the need to restore the biodiversity, ecosystem health, and ecosystem services provided by coastal landforms and habitats, especially in the light of climate change. The second edition reports on progress made on practices identified in the first edition, presents additional case studies, and addresses new and emerging issues. It analyzes the tradeoffs involved in restoring beaches and dunes - especially on developed coasts - the most effective approaches to use, and how stakeholders can play an active role. The concept of restoration is broad, and includes physical, ecological, economic, social, and ethical principles and ideals. The book will be valuable for coastal scientists, engineers, planners, and managers, as well as shorefront residents. It will also serve as a useful supplementary reference textbook in courses dealing with issues of coastal management and ecology.
This thorough and informative volume presents a set of detailed,
globally applicable techniques for seagrass research.

Written by Chris Maser, one of the architects of the sustainability movement, Interactions of Land, Ocean and Humans: A Global Perspective explores a critical number of the myriad aspects that comprise the great, reciprocal feedback loops between the mountain peaks, the deep sea, and everywhere in between. Maser's exploration of these connections gives us the tools required to open our imaginations and our scientific literacy, offering insights into the relationships between the land, sea, and people that could influence us toward better decisions. The author examines the hydrological cycle, hydrological continuum, and anthropogenic pollution of various kinds from the atmosphere to deep belowground. He also highlights connections by detailing how human behavior changes the atmosphere, which changes the oceans, which alters the climate, which alters the atmosphere and thus the ocean, and so on. The book then explores the biophysical commonalities between landscapes and seascapes, as well as the habitats, in each realm. It covers marine fisheries; marine protected areas; oceans as a commodity, as part of the global commons, as a biophysical living trust for which we are the trustees and the children of today and beyond are the beneficiaries; and more. Can we arrest this deleterious process? Yes, but it will take a dramatic shift in human behavior worldwide. Why? Because, just as the collective human behavior and lack of awareness caused the problems in the first place, the level of consciousness that caused the problem is not the level of consciousness that can fix it. We must shift our thinking from that which is symptomatic to that which is systemic if we are to have a sustainably productive environment through time. Maser gives us the understanding of the biophysical interactions among the lands, oceans, and peoples of the world needed to create sustainable solutions to environmental problems.
The oceans cover more than 70% of the earth's surface to an average depth of almost 4000 metres. It is therefore not surprising that exchanges that occur between ocean and atmosphere exert major influences on the global climate. In addition, there is great variety within the expanses of the ocean, including large temperature differences, and enormous biodiversity brought about by the great chemical diversity within the marine environment. Written by international experts in the field, Chemistry in the Marine Environment offers a multidisciplinary and authoritative review of this important topic. Included is a review of the opportunities and challenges in developing new pharmaceuticals from the sea and an examination of contamination and pollution in the marine environment, which is a cause of great concern world-wide. The international perspective of this book will engage the interest and attention of a wide readership, from chemical oceanographers to policymakers, from students in environmental science to those in oceanography programmes.
This work provides a wide perspective of the oceans by examining their places in the earth sciences, drawing together all the key strands of ocean study and presenting a holistic view of ocean processes, ancient and modern.
This manual describes the wide range of electromechanical, electrochemical and electro-optical transducers at the heart of current field-deployable ocean observing instruments. Their modes of operation, precision and accuracy are discussed in detail. Observing platforms ranging from the traditional to the most recently developed are described, as are the challenges of integrating instrument suits to individual platforms. Technical approaches are discussed to address environmental constraints on instrument and platform operation such as power sources, corrosion, biofouling and mechanical abrasion. Particular attention is also given to data generated by the networks of observing platforms that are typically integrated into value-added data visualization products, including numerical simulations or models. Readers will learn about acceptable data formats and representative model products. The last section of the book is devoted to the challenges of planning, deploying and maintaining coastal ocean observing systems. Readers will discover practical applications of ocean observations in diverse fields including natural resource conservation, commerce and recreation, safety and security, and climate change resiliency and adaptation. This volume will appeal to ocean engineers, oceanographers, commercial and recreational ocean data users, observing systems operators, and advanced undergraduate and graduate students in the field of ocean observing.
