Among the deep-sea marine invertebrates, pycnogonids and crustaceans represent ecologically important and most diverse groups of species. Yet both are still poorly understood. Sampling and exploring operations off the west and east coast of the Americas has significantly increased in the last two decades. However such operations are very costly and limited in number and frequency. In countries like Brazil, Canada, Chile, Colombia, Costa Rica, Mexico, Peru, the United States of America, and El Salvador a large effort has been made to explore the deep-sea resources and the rich diversity of the communities, resulting in a better understanding of the natural ecosystems on both coasts of America. Pycnogonids and many groups of deep-sea crustaceans have been intensively studied, from the smallest animals, like the mostly unknown benthic copepods to the largest decapods. This book presents new and updated information on various groups of deep-sea pycnogonids and crustaceans occurring off the American continent. Offering a valuable reference resource for scientists interested in this fascinating fauna, it includes review papers and new data on the deep-sea communities occurring off the USA, Mexico, El Salvador, Costa Rica, Colombia, Chile, Peru, Brazil and Argentina, as well as in larger areas in both the East Pacific and the West Atlantic. As such it covers most of the current deep-water research in Latin America.

From the bestselling author of Breath, a “fascinating, informative, exhilarating” voyage from the ocean’s surface to its darkest trenches (Wall Street Journal).

Fascinated by the sport of freediving—in which competitors descend great depths on a single breath—James Nestor embeds with a gang of oceangoing extreme athletes and renegade researchers. He finds whales that communicate with other whales hundreds of miles away, sharks that swim in unerringly straight lines through pitch-black waters, and other strange phenomena. Most illuminating of all, he learns that these abilities are reflected in our own remarkable, and often hidden, potential—including echolocation, directional sense, and the profound bodily changes humans undergo when underwater.

Along the way, Nestor unlocks his own freediving skills as he communes with the pioneers who are expanding our definition of what is possible in the natural world, and in ourselves.

The book gives an overview of the tectonic, geological, potential fields, etc maps of the Arctic that were compiled during geological and geophysical studies conducted in the Arctic over the past 15 years under the International project "Atlas of Geological Maps of the Circumpolar Arctic at a scale of 5M" and presents the results of geological, geophysical, paleogeographic and tectonic studies carried out in the Arctic Ocean and the Eastern Arctic during the implementation of national mapping and scientific programmes and studies intended to provide scientific substantiation for the extension of the continental shelf (ECS). Given its scope, the book will appeal to a wide range of geologists.

This book provides a comprehensive overview of recent research on estuaries of the east coast of India, and how changing biogeochemical dynamics as a result of climate change and human activity have impacted estuaries and other open water ecosystems. Though estuaries only cover a very small portion of the earth's hydrosphere, they are some of the most biogeochemically active regions among the global water bodies. As such, this book focuses on estuaries of the east coast of India going all the way to the Bay of Bengal, which is the world's largest freshwater input from perennial rivers and rain-fed estuaries, and is therefore a unique area of study. Through its unique coverage of the Bay of Bengal in particular, the book presents a new perspective not present in the literature on estuary biogeochemistry and ecosystem dynamics. Moreover, the book addresses SDG 13 (Climate Action) and 14 (Life below Water), with a focus on ecosystem services of the natural aquatic system.The book will be useful to researchers, policy makers, coastal managers and marine sustainability scientists and organizations.

This book collects multidisciplinary chapters on the most important problems that arise at mid-ocean ridges. The mid-ocean ridge system is the longest continuous feature of the earth's surface. It is where the great majority of ocean floor is created and volumes of seafloor volcanism vastly exceed those on land. It provides the means for much of the heat loss from the interior of the earth. Chemicals as well as heat are extracted by flowing seawater through the rocks of the seafloor, leading to spectacular areas of hydrothermal venting, that affect ocean chemistry and global climate. The chapters range from studies of the mantle and magma generation within it, through tectonics of mid-ocean ridges, to the physical, chemical and biological dynamics of hydrothermal systems. The book will be of importance to specialists and researchers wishing to become informed of the latest developments in the science of mid-ocean ridges. It will prove especially useful for new scientists entering the field.

This encyclopedia is a reference for aquatic physical, biological and biogeochemical sciences, collecting and connecting a number of topics, concepts and facts about aquatic systems and their scientific investigation. The scope of the book comprises the aquatic physiosphere-biosphere transition zone, an entity that encompasses both inanimate matter and collectives (the physiosphere) as well as living organisms and collectives (the biosphere). This combined approach is meaningful because both realms are intimately linked and because available methods of investigation are often similar. Much can be gained from considering both spheres at and across their interface jointly, and while there is a strong focus on marine systems, most concepts presented are also applicable to freshwater systems. This presented snapshot of knowledge of the transition zone between the aquatic physiosphere and biosphere is taken from a very specific angle: the point of view of a modeler. Modeling is not only a state-of-the-art mode of scientific investigation, but also requires the explicit specification of all assumptions (helping to avoid fallacies), and offers the advantage of being quantitative and allows for theoretical "what if" scenarios. As in any reference work, equal emphasis is given to fundamental facts, the definition of terms and the explanation of concepts, in an attempt to establish a joint language for physicists, biologists and biogeochemists. Although originating from a modeler's approach to nature, the resulting suite of compatible concepts may also be useful beyond modeling purposes. Furthermore, the material is presented in a condensed, straightforward way. Hence, the length of each entry is limited to one (occasionally two) pages, thus offering a quick introductory overview. This excludes lengthy derivations and very specialized details. The book is geared towards researchers, teachers and advanced students in the field of aquatic (marine and limnic) sciences, in particular those interested or involved in interdisciplinary work.

Britain's maritime tradition is well documented. The management of its marine and coastal environment is therefore of tantamount importance, and offers lessons for other nations across the world. The beginning of the new millennium marks a major, long-term turning point in the historical development of Britain's maritime interest discernible by continued diversification and intensification in the uses of the sea; unprecedented and often adverse environmental impacts engendered by these uses; and the beginning of a major effort to establish a comprehensive management system which can deal with both multiple uses and environmental impacts.
This collection, featuring an impressive list of contributors, covers themes including maritime history, environmental issues, public policy, tourism, technology and resources as well as open sea development and management. It is a useful addition for those interested in geography, the environment, maritime studies and also engineering.

Until a few decades ago, the ocean depths were almost as mysterious and inaccessible as outer space. Oceans cover two-thirds of the earth's surface with an average depth of more than two miles--yet humans had never ventured more than a few hundred feet below the waves. One of the great scientific and archaeological feats of our time has been finally to cast light on the "eternal darkness" of the deep sea. This is the story of that achievement, told by the man who has done more than any other to make it possible: Robert Ballard. Ballard discovered the wreck of the Titanic. He led the teams that discovered hydrothermal vents and "black smokers"--cracks in the ocean floor where springs of superheated water support some of the strangest life-forms on the planet. He was a diver on the team that explored the mid-Atlantic ridge for the first time, confirming the theory of plate tectonics. Today, using a nuclear submarine from the U.S. Navy, he's exploring the ancient trade routes of the Mediterranean and the Black Sea for the remains of historic vessels and their cargo. In this book, he combines science, history, spectacular illustrations, and first-hand stories from his own expeditions in a uniquely personal account of how twentieth-century explorers have pushed back the frontiers of technology to take us into the midst of a world we could once only guess at. Ballard begins in 1930 with William Beebe and Otis Barton, pioneers of the ocean depths who made the world's first deep-sea dives in a cramped steel sphere. He introduces us to Auguste and Jacques Piccard, whose "Bathyscaph"descended in 1960 to the lowest point on the ocean floor. He reviews the celebrated advances made by Jacques Cousteau. He describes his own major discoveries--from sea-floor spreading to black smokers--as well as his technical breakthroughs, including the development of remote-operated underwater vehicles and the revolutionary search techniques that led to the discovery and exploration of the Titanic, the Nazi battleship Bismarck, ancient trading vessels, and other great ships. Readers will come away with a richer understanding of history, earth science, biology, and marine technology--and a new appreciation for the remarkable men and women who have explored some of the most remote and fascinating places on the planet.

This book provides a complete and current overview of the correlation between ocean conditions and human health, publishing comprehensively for the first time on the direct interactions among oceanography, marine biology and impacts on human health. Specifically the text addresses how changing ocean conditions result in health impacts and disruptions, with a focus on cases in the USA. The changing ocean conditions that are discussed include diminishing marine biodiversity, climactic changes such as intensified weather events, shifting sea currents and increasing sea temperature. The book addresses the resulting health issues brought about by these various ocean conditions, such as emerging infectious diseases, starvation and poisoning among impacted communities, toxic algae blooms, threatened ecosystems, and other future implications. The text was developed in conjunction with scientists from Brown University, the University of Rhode Island, the University of Texas at Austin, the University of California at Riverside and Ochsner Health, all located in areas deeply impacted by the changing Oceans. The book will be of interest to marine research scientists, health care professionals, students, and general enthusiasts of oceanography and health.

This book gives a comprehensive treatment of coastal evolution and dynamics, providing background for the study of coastal landforms and how and why they are changing, with up to date information, world-wide coverage of examples, numerous illustrations and extensive references to the scientific literature. Coastal Geomorphology: An Introduction gives a systematic approach to the subject of coastal geomorphology, dealing with the shaping of landforms, the changing levels of land and sea, the array of coastal processes that have influenced the shaping of landforms and the changes that are taking place on them. It analyses the causes of erosion and accretion on sectors of the coastline and examines the factors that have contributed to these, preparing the way for management strategies. This book includes discussions on the effects that human activities have had on coasts and their continuing contributions to coastal landform changes. This book is an essential read for undergraduate and graduate students in geomorphology, geography, marine science and coastal management courses, anyone concerned with coastal planning, development and management, and organisations concerned with conservation and use of the coast.

This book focuses on the survey technology, post-processing technology, mapping technology and scientific application of the submarine topography and geomorphology in detail. High-resolution submarine geomorphology is a frontier branch of marine geology and marine surveying and mapping, which provides a direct basis to study the seabed surface, to understand the tectonic movement and submarine evolution. In the past two decades, high-resolution submarine geomorphology with high-precision multi-beam echo sounding, side-scan sonar and sub-bottom profiler as the major techniques, is developing very quickly and is one of the frontiers of international marine science and technology. These high techniques promote the traditional submarine geomorphology to high-resolution and quantitative research. At present, high-resolution submarine geomorphology is widely used in the delimitation of the continental shelf, the international seabed resources survey, marine engineering and marine military applications. In order to facilitate readers to understand how to acquire and apply scientific research based on submarine topographic data, it highlights the combination of theory, technology and scientific application. This book is useful as a reference for professional and technical personnel in related fields and also as a textbook for both graduate and undergraduate students as well.

This volume lays the physical and conceptual groundwork for the Pacific World series, exploring both the constraints imposed and the opportunities offered to humanity by the physical environment of the Pacific region. Organized from the perspectives of "Big History" and macro-geography, the volume presents a series of major studies and surveys by authors from a range of disciplines. It opens with perspectives on the ocean, and closes with questions of human settlement, diffusion, and trans-Pacific contacts. Geologists write of the origins of the Pacific, its geological structure, and the problem of tsunamis; climatologists and oceanographers discuss the El NiA+/-o Southern Oscillation and the ocean waters; biologists and biogeographers find patterns in the life of the Basin - as is shown, all these have their impact on the potential of the region for human use and settlement. Finally, geographers, anthropologists, and archaeologists deal with the peopling of the Pacific islands, the settlement of the Americas, and the incidence and importance of pre-modern links across the Pacific.

Engineers dreams and fossil energy replacement schemes can come true. Man has been tapping the energy of the sea to provide power for his industries for centuries. Tidal energy combined with that of waves and marine winds rank among those most successfully put the work. Large scale plants are capital intensive but smaller ones, particularly built in China, have proven profitable. Since the initiation of the St Malo project in France, similar projects have gone into active service where methods have been devised to cut down on costs, new types of turbines developed and cost competitiveness considerably improved. Tidal power has enormous potential. The book reviews recent progress in extracting power from the ocean, surveys the history of tidal power harnessing and updates a prior publication by the author."

This book presents the biodiversity of the Brazilian deep-sea and its many unique geological and biological features, as well as a review of its ecology, conservation, and future research needs. The deep-sea Brazilian margin has an incredible geological heterogeneity with numerous characteristic seafloor features, and latitudinal changes in marine productivity, oceanographic conditions and biological communities have resulted in very distinct biological assemblages at regional and bathymetric scales. It is a tremendously rich ecosystem in terms of living species, from which many well-known historical tales have originated, and with unique importance for the global climate and humanity. Nevertheless, vast areas of the Brazilian margin have been explored for fishing, oil and gas, and other commodities, likely impacting a variety of deep-sea habitats at scales and intensities yet undetermined. This book is intended for students, scholars, professionals and a wide audience interested in the deep-sea in general and, more specifically, in the South Atlantic deep-sea.

The ocean and its inhabitants sketch and stretch our understandings of law in unexpected ways. Inspired by the blue turn in the social sciences and humanities, Blue Legalities explores how regulatory frameworks and governmental infrastructures are made, reworked, and contested in the oceans. Its interdisciplinary contributors analyze topics that range from militarization and Maori cosmologies to island building in the South China Sea and underwater robotics. Throughout, Blue Legalities illuminates the vast and unusual challenges associated with regulating the turbulent materialities and lives of the sea. Offering much more than an analysis of legal frameworks, the chapters in this volume show how the more-than-human ocean is central to the construction of terrestrial institutions and modes of governance. By thinking with the more-than-human ocean, Blue Legalities questions what we think we know-and what we don't know-about oceans, our earthly planet, and ourselves. Contributors.

This book investigates Reliability-based Multidisciplinary Design Optimization (RBMDO) theory and its application in the design of deep manned submersibles (DMSs). Multidisciplinary Design Optimization (MDO) is an effective design method for large engineering systems like aircraft, warships, and satellites, which require designers and engineers from various disciplines to cooperate with each other. MDO can be used to handle the conflicts that arise between these disciplines, and focuses on the optimal design of the system as a whole. However, it can also push designs to the brink of failure. In order to keep the system balanced, Reliability-based Design (RBD) must be incorporated into MDO. Consequently, new algorithms and methods have to be developed for RBMDO theory. This book provides an essential overview of MDO, RBD, and RBMDO and subsequently introduces key algorithms and methods by means of case analyses. In closing, it introduces readers to the design of DMSs and applies RBMDO methods to the design of the manned hull and the general concept design. The book is intended for all students and researchers who are interested in system design theory, and for engineers working on large, complex engineering systems.

Over the last few decades many studies have focused on the oxygen depletion of coastal and oceanic waters. An understanding of the processes involved is fundamental to assess the effects of global and climatic changes and to support an ecosystem approach to adaptive environmental management for coastal seas and ocean basins. This timely book presents the state-of-the-art of our knowledge of the nature and chemical structure of redox interfaces in a marine water column, oxygen depletion and connected processes. The structures of the redox layers, including the distribution of certain parameters and microbiological features, are described in detail. The volume also covers studies devoted to the interannual variability of some oxygen-depleted systems, modeling and new developments in observation techniques. In addition, it identifies remaining gaps in our knowledge of the cycling of chemical elements in changing redox conditions. The chapters are based on extensive observational data, collected by the authors during sea and shore expeditions, on archive data, and on a broad range of scientific literature.

This book is intended to meet the needs of those who seek to develop control systems for ROVs when there is no model available during the initial design stage. The modeling, simulation and application of marine vehicles like underwater robotic vehicles (URVs) are multidisciplinary, and combine mathematical aspects from various engineering disciplines. URVs such as remotely operated vehicle (ROVs) are used for a wide range of applications such as exploring the extreme depths of our ocean, where a hard-wired link is still required. Most ROVs operate in extreme environments with uncertainties in the model prior to control system design. However, the method involved extensive testing before the system model could be used for any control actions. It has been found that the range of error can be extensive and uncertain in actual, continuously varying conditions. Hence, it is important to address the problem of reliance on model testing using different modeling approaches. In this book, approaches such as WAMIT, ANSYS-CFX, STAR CCM+, MATLAB and Simulink are used to model parameters for ROVs. A few benchmark models are provided, allowing researchers and students to explore and test different control schemes. Given its scope, the book offers a valuable reference guide for postgraduate and undergraduate students engaged in modeling and simulation for ROV control.

This book explores computational fluid dynamics applied to ship hydrodynamics and provides guidelines for the future developments in the field based on the Tokyo 2015 Workshop. It presents ship hull test cases, experimental data and submitted computational methods, conditions, grids and results. Analysis is made of errors for global (resistance, sinkage, trim and self-propulsion) and local flow (wave elevations, mean velocities and turbulence) variables, including standard deviations for global variables. The effects of grid size and turbulence models are evaluated for both global and local flow variables. Detailed analysis is made of turbulence modeling capabilities for capturing local flow physics. Errors and standard deviations are also assessed for added resistance (captive test cases) and course keeping/speed loss (free running test cases) in head and oblique waves. All submissions are used to evaluate the error and uncertainty by means of a systematic verification and validation (V&V) study along with statistical investigations.
