The NATO Advanced Study Institute on Adaptive Methods in Underwater Acoustics was held on 30 July - 10 August 1984 in LLineburg, Germany. The Institute was primarily concerned with signal processing for underwater appl ica tions. The majority of the presentations, when taken together, yield a definite picture of the present status of understanding of adaptive and high resolution processing, setting out the progress achieved over the past four years together with the major problem areas remaining. Major effort was made to obtain a commensurate contribution of tutorial and advanced research papers. It is my hope that the material in this volume may be equally well suited for students getting an introduction to some of the basic problems in underwater signal processing and for the professionals who may obtain an up-to-date overview of the present state of the art. This might be especially useful in view of the controversy and lack of adequate interrelationships which have marked this rapidly expanding field in the past. Practical reinforcement of this picture is provided by the material concerning digital and optical processing technology, giving some guidance to achievable adaptive and high resolution techniques with current processing devices. The formal programme was extended and detailed by a series of six evening work shops on specific topics, during which informal discussions took place among the participants. Summaries of these workshops are also included in these Proceedings."

The book deals with the processes in marine environment with particular emphasis on the interface processes (sediments- water and atmosphere-water) regarding organic matter and energy fluxes, carbon dioxide intake and transformation. Particular analytical methodologies concerning biosensors for analysis in situ are discussed.

Increasingly, neural networks are used and implemented in a wide range of fields and have become useful tools in probabilistic analysis and prediction theory. This booka "unique in the literaturea "studies the application of neural networks to the analysis of time series of sea data, namely significant wave heights and sea levels. The particular problem examined as a starting point is the reconstruction of missing data, a general problem that appears in many cases of data analysis.

Specific topics covered include:

* Presentation of general information on the phenomenology of waves and tides, as well as related technical details of various measuring processes used in the study

* Description of the model of wind waves (WAM) used to determine the spectral function of waves and predict the behavior of SWH (significant wave heights); a comparison is made of the reconstruction of SWH time series obtained by means of neural network algorithms versus SWH computed by WAM

* Principles of artificial neural networks, approximation theory, and extreme-value theory necessary to understand the main applications of the book.

* Application of artificial neural networks (ANN) to reconstruct SWH and sea levels (SL)

* Comparison of the ANN approach and the approximation operator approach, displaying the advantages of ANN

* Examination of extreme-event analysis applied to the time series of sea data in specific locations

* Generalizations of ANN to treat analogous problems for other types of phenomena and data

This book, a careful blend of theory and applications, is an excellent introduction to the use of ANN, which may encourage readers to try analogous approachesin other important application areas. Researchers, practitioners, and advanced graduate students in neural networks, hydraulic and marine engineering, prediction theory, and data analysis will benefit from the results and novel ideas presented in this useful resource.

This book comprises selected proceedings of the Fourth International Conference in Ocean Engineering (ICOE2018), focusing on emerging opportunities and challenges in the field of ocean engineering and offshore structures. It includes state-of-the-art content from leading international experts, making it a valuable resource for researchers and practicing engineers alike.

Seafloor surveying with acoustic remote sensing has become a powerful tool for researchers and professionals seeking knowledge about the structure and behavior of the seafloor. In particular, sidescan sonar is proving to be the preeminent technique, but its data is often difficult to interpret due to the physics of acoustic remote sensing, and to the varied geological processes at play. This handbook not only presents all the fundamentals but also explains how to interpret sidescan sonar imagery and bathymetry. It fully explores the most recent advances, both in the technology and in the knowledge of marine structures, and provides deep insights for interpretation and decision-making. Broadly expanded and updated from the previous 1997 Handbook of Seafloor Sonar Imagery, this handbook is indispensable to oceanographers, resource exploiters, telecommunications engineers, and marine researchers of all kinds."

Marine biological science is now studied at the molecular level and although research scientists depend on information gained using molecular techniques, there is no book explaining the philosophy of this approach. Molecular Approaches to the Study of the Ocean introduces the reasons why molecular technology is such a powerful tool in the study of the oceans, describing the types of techniques that can be used, why they are useful and gives examples of their application. Molecular biological techniques allow phylogenetic relationships to be explored in a manner that no macroscopic method can; although the book deals with organisms near the base of the marine food web, the ideas can be used in studies of macroorganisms as well as those in freshwater environments.

The Arctic region has long held a fascination for explorers and scientists of many countries. Despite the numerous voyages of exploration, the na ture of the central Arctic was unknown only 90 years ago; it was believed to be a shallow sea dotted with islands. During Nansen's historic voyage on the polarship Fram, which commenced in 1893, the great depth of the central basin was discovered. In the Soviet Union, investigation of the Arctic Ocean became national policy after 1917. Today research at several scientific institutions there is devoted primarily to the study of the North Polar Ocean and seas. The systematic exploration of the Arctic by the United States com menced in 1951. Research has been conducted year-round from drifting ice islands, which are tabular fragments of glacier ice that break away from ice shelves. Most frequently, ice islands originate off the northern coast of Ellesmere Island. These research platforms are occupied as weather sta tions, as well as for oceanographic and geophysical studies. Several inter national projects, conducted by Canadian, European, and U. S. groups, have been underway during the last three decades. Although much new data have accumulated since the publication of the Marine Geology and Oceanography of the Arctic Seas volume in 1974 (Yvonne Herman, ed. ), in various fields of polar research-including present-day ice cover, hydrogra phy, fauna, flora, and geology-many questions remain to be answered.

This book will cover the fundamental principles of measuring oceans from space, but will contain state-of-the-art developments in data analysis and interpretation and in sensors. Completely new will be material covering advances in oceanography that have grown out of remote sensing, including some of the global applications of the data. The variety of applications of remotely sensed data to ocean science has grown significantly and new areas of science are emerging to exploit the gobal datasets being recovered by satellites, particularly in relation to climate and climate change, basin-scale, air-sea interaction processes (e.g. El Niño) and the modelling, forecasting and prediction of the ocean.

The oceans provide a truly millennial challenge for both the development and management of planet earth by humankind. Awareness of the nature and scale of this challenge, the opportunities and the limitations, has been developing over the past three decades. In particular, new approaches to the development of the law of the sea, the division of the oceans among states, and new thinking on institutions will be needed in the transition to the new millennium. Understanding of the newness of the challenges has to be underpinned by understanding of the uses of the sea in terms of major sectors, and recognition of the importance of the many regional worlds of perception, understanding and action which link the diverse ocean environment to the diversity of human culture. This book covers all these themes in depth. It is aimed at both academics and students in higher education, and practitioners in the rapidly growing fields of ocean and coastal management in the public, private, and voluntary sectors.

The biennial conferences of the Society for Underwater Technology have achieved an excellent reputation for the quality of their presentations, which cover topics of the most acute current interest, as well as those at the forefront of review and development. The 1994 conference on Subsea Control and Data Acquisition formed no exception, since it covers subjects at the cutting edge of modern technology. It is a matter of increasing concern that products are becoming overspecified, resulting in excessive costs and longer development schedules, while not conferring an equivalent benefit in reliability of the finished product. Subsea Control and Data Acquisition is vital reading for all subsea control system designers, manufacturers and operators, equipment consultants, application engineers, academics in the subsea engineering field, and all subsea engineers.

In the framework of the Diderot Mathematical Forum (DMF) of the European Mathematical Society (EMS), December 19-20, 1997, a Videoconference was held linking three teams of specialists in Amsterdam, Madrid and Venice respectively. The general subject of this videoconference, the second one of the DMF series, was Mathematics and Environment and more specifically, Problems related to Water.

This volume contains the texts of the Madrid site contributions with important, new and unpublished, examples on the modeling, mathematical and numerical analysis and treatment of the associated control problems of relevant questions arising in Oceanography and Environment.

On decadal time scales, climate change may result not only from man-made causes, but also from natural processes. This book brings together theoretical conceptions of the physical mechanisms of climate change with observational evidence of these changes. The following key topics are included: Observed Climatic Variability, Predictability of the Atmosphere and Oceans from Days to Decades, and Mechanisms for Decadal to Centennial Climate Variability. Further, there are specialised contributions on the role of the oceanic circulation in climate change. The authors are renowned for their pedagogical skills, and the book is primarily designed for beginners in the field, who have a background in physical science. In addition, it is an invaluable source of information for scientists seeking an overview on climate dynamics.

The first single-volume reference of its kind, this comprehensive handbook provides background information and analysis on the full range of contemporary ocean use issues. Coverage includes the development of ocean law, the evolving uses of oceans, data on living and non-living ocean resources, the environmental impact of pollution, and competing national claims over ocean exploration. The volume also summarizes the most current research available on the uses of oceans, incorporates the salient portions of the 1982 Law of the Sea Convention in the topical surveys and analyses presented, and discusses all of the other major international conventions that have dealt with global ocean or marine affairs. Students, researchers, and agency staff concerned with the political and legal dimensions of ocean use will find this an indispensable source.

The handbook begins with an overview of the world's oceans and their physical and geographic features. The next two chapters survey the international conferences that have been held on ocean use and explore the historical development of international principles on the law of the sea. Ocean resources and their economic and political management form the focus of the following four chapters, with separate chapters on living and non-living resources and deep seabed mining. The final chapters address ocean environmental protection and pollution prevention and the implications of various uses of the ocean: military, navigation and transport, and marine scientific research. The text is accompanied by numerous charts and tables, end-of-chapter references, and seven appendixes which contain valuable supplemental information such as a chronological list of conventions and treaties on the law of the sea, national legislation on exclusive economic zones, bilateral fishery agreements, and more.

These proceedings are a collection of 16 selected scientific papers and reviews by distinguished international experts that were presented at the 4th Pacific Rim Underwater Acoustics Conference (PRUAC), held in Hangzhou, China in October 2013. The topics discussed at the conference include internal wave observation and prediction; environmental uncertainty and coupling to sound propagation; environmental noise and ocean dynamics; dynamic modeling in acoustic fields; acoustic tomography and ocean parameter estimation; time reversal and matched field processing; underwater acoustic localization and communication as well as measurement instrumentations and platforms. These proceedings provide insights into the latest developments in underwater acoustics, promoting the exchange of ideas for the benefit of future research.

The Tethys oceanic realm, which separated North America, Europe, and Asia from South America, Africa, India, Australia, and Antarctica during the Mesozoic period, offers unique insights into the evolution of a fossil ocean and of the Earth's global behavior. This eighth volume in The Ocean Basins and Margins series, the first exploration of an ancient ocean, examines the Tethys from a multitude of perspectives. The book describes the results of a five-year, multidisciplinary research project (the Tethys project), which involved the collaboration of more than 100 international experts. Highlights of this extraordinary reference include a synthesis of the plate-tectonic history of Tethys, featuring new data on its geodynamic evolution; revealing Mesozoic paleogeographic reconstructions; a series of syntheses of Tethyan resources and sedimentation; and discussions on the part played by Tethys in the evolution of the Northern Andes. In addition, the volume introduces the concept of seuils lithospheriques, physiographic cratonic barriers that influenced Tethyan ocean dynamics. Extensive bibliographies make this volume an excellent sourcebook for investigators conducting ongoing research in this area.

On April 1, 1946, shortly after sunrise, the town of Hilo on the island of Hawai'i was devastated by a series of giant waves. Traveling 2,300 miles from the Aleutian Islands in less than five hours, the waves struck without warning and claimed 159 lives. Fourteen years later, on May 22, 1960, a massive earthquake occurred off of the coast of Chile. The earthquake generated giant waves that sped across the Pacific at 442 miles per hour, reaching Hilo in just fifteen hours. The first wave to hit the town was a modest four feet higher than normal, the second nine feet. Before the third wave could arrive, a tidal phenomenon known as a bore smashed into the Hilo bayfront, with thirty-five foot waves that wrenched buildings off their foundations. That day several city blocks were swept clean of all structures and 61 people died. The first edition of Tsunami!, published in 1988, provided readers with a complete examination of the tsunami phenomenon in Hawai'i. This second edition adds many eyewitness accounts of the tsunamis of 1946 and 1960 and expands its coverage to include major tsunamis in the Mediterranean and off the coasts of Japan, Chile, Indonesia, Fiji, Alaska, California, Newfoundland, and the Caribbean, as well as the 1998 devastation in Papua New Guinea. Dramatic photographs and accounts of experiencing a tsunami firsthand are placed within the framework of the how and why of tsunamis, our scientific understanding of these phenomena, and the current status of the Tsunami Warning System, which is widely used to forecast and measure tsunamis and prepare coastal areas for potentially deadly tsunami strikes.

A Journey Through Tides is a fully comprehensive text on the history of tides. It brings together geology and oceanography and discusses, in detail, new ideas that have emerged about how tectonics and tides interact. In addition, the book provides an overview of Earth's history, from the perspective of tidal changes, while also highlighting other fascinating phenomena (e.g., solid Earth tides and links between tides and earthquakes). Sections cover an introduction to tides for oceanography students and scientists from other disciplines, cover the Earth's deep time processes, and include several case studies of specific topics/processes that apply to a earth science disciplines. There are many other processes that drive and modify the tides, hence this book also describes why there is a tide, how it has changed since Earth's early days, and what consequences the tides, and changes in the tides, have on other parts of the Earth system.

This book describes the progress that has been made in the study of the process of ice rafting. It includes chapters on the concept of ice rafting and ice rafting and climate change. The main focus of the book is the reconstruction of past ice drift directions and their significance for an understanding of the global oceanic and atmospheric circulation.

This book deals with a number of contentious issues in Chinese management as China emerges as a global economic player, with a greater role in international business during a global economic crisis. This step is in tandem with an economically driven foreign policy. Since the 1980s, Chinese management while still in transition, has benefited from an infusion of capital, technology and managerial expertise through inward direct investment via joint and wholly-owned foreign ventures. As the so-called 'workshop of the world', China and its exports, especially labour-intensive goods, face protectionism in the United States and the European Union. To circumvent these barriers, the Chinese leaders are emphasising domestic consumption, itself dependent on rising personal income levels and an improved national social insurance system, and a move to high-tech products, themselves requiring indigenous innovation. The creation of a knowledge economy, in addition to outward investment in manufacturing, could lead to a distinctive independent style of Chinese management. Simultaneously, China's participation in intra-regional trade underlines the nation's role in Asian regional business networks. Such developments in turn present a challenge to Western and global business. This book was published as a special issue of Asia Pacific Business Review.

The second edition of this book has been completely updated. It studies the history and gives an analysis of extreme climate change on Earth. In order to provide a long-term perspective, the first chapter briefly reviews some of the wild gyrations that occurred in the Earth's climate hundreds of millions of years ago: snowball Earth and hothouse Earth. Coming closer to modern times, the effects of continental drift, particularly the closing of the Isthmus of Panama are believed to have contributed to the advent of ice ages in the past three million years. This first chapter sets the stage for a discussion of ices ages in the geological recent past (i.e. within the last three million years, with an emphasis on the last few hundred thousand years).

Over the past decade the significant advances in real-time ocean observing systems, ocean modelling, ocean data assimilation and super-computing has seen the development and implementation of operational ocean forecast systemsof the global ocean. At the conclusion of the Global Ocean Data Assimilation Experiment (GODAE) in 2008 ocean analysis andforecasting services were being supported by 12 international centres.

This book is about ocean forecasting - a maturing field which remains an active area of research, and includes such topics as ocean predictability, observing system design, high resolution ocean modelling and ocean data assimilation. It presents the introduction to ocean forecasting which provides a foundation for new opportunities in areas of coupled bio-geochemical forecasting and coupled atmosphere-wave-ocean forecasting. The book describesan updated account ofresearch and development to improve forecast systems, determining how best to service the marine user community with forecast information as well as demonstrating impact to their applications. It also discusses operational centresthat are now supporting a range of real-time ocean services including online graphical and data products for their user communities and their feedback on the quality of information.

The contents of this book are aimed at early career scientists and professionals with an interest in operational oceanography and related ocean science. There are excellent opportunities for exciting careers in the emerging field of operational oceanography in order to address current and future challenges as well as provide the supporting services to a rapidly growing user community.
