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.

Leander McCormick literally fished his way around the world. These many miles produced a catalog of stories in his book. From his first perch on the shores of Lake Michigan, to youthful pursuits of eels in England, to ultimate angling for the giants of the sea, he demonstrates a deep insight into both the fish and the people who pursue them. Having angled for and caught dozens of different species of fish, McCormick dryly comments, "Some were more sport to catch than others, but I assert that all fishing is good, though some is better."

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.

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.

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.

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.

The Juan Fernandez Archipelago is located in the Pacific Ocean west of Chile at 33 Degrees S latitude. Robinson Crusoe Island is 667 km from the continent and approximately four million years old; Alejandro Selkirk Island is an additional 181 km west and only one million years old. The natural impacts of subsidence and erosion have shaped the landscapes of these islands, resulting in progressive changes to their subtropical vegetation. The older island has undergone more substantial changes, due to both natural causes and human impacts. After the discovery of Robinson Crusoe Island in 1574, people began cutting down forests for lumber to construct boats and homes, for firewood, and to make room for pastures. Domesticated plants and animals were introduced, some of which have since become feral or invasive, causing damage to the local vegetation. The wealth of historical records on these activities provides a detailed chronicle of how human beings use their environment for survival in a new ecosystem. This book offers an excellent case study on the impacts that people can have on the resources of an oceanic island.

This book is focused on fundamental aspects of climate variability in the ocean, in particular changes of the wind-driven circulation. The vertical movement of isopycnal (isothermal) layers, including their stretching and compression, is called heaving and stretching. A major part of climate variability in the ocean is heaving in nature. Heave is primarily associated with the adiabatic motions of isopycnal layers due to change of wind stress. It is rather difficult to separate the contributions from adiabatic and diabatic processes. Isopycnal analysis has been widely used in climate study; however, it is much more accurate to study the isopycnal layers. Here climate signals are examined in terms of changes of layer depth, layer thickness, layer temperature/salinity, spicity and others. In addition to the traditional Theta-S diagram, the sigma-pi (potential density - potential spicity) diagram can also be used in analyzing water mass property distribution and climate variability. In fact, a radius of signal can be defined rigorously for signals in the sigma-pi diagram; the combination of isopycnal analysis and evaluation of radius of signal provides a powerful tool in analyzing climate variability in the world oceans.

Scientists and the Sea is a history of how the scientific study of the sea has developed over a period of nearly 2500 years. Beginning with the speculations of Greek philosophers it carries the story forward, showing how curiosity about the ocean appeared in many different forms and locations before, in the late 19th century, the first deep-sea researches heralded the foundation of the science known today as oceanography. Originally published in 1971, this book has never been superseded as the most comprehensive and wide-ranging treatment of the emergence of marine science within the western scientific tradition. After three introductory chapters dealing with knowledge up to the Renaissance, the main part of the work shows how pioneers of scientific observation at sea during the 17th and 18th centuries made notable discoveries, but that it was not until the middle of the 19th century when, aided by the advance of technology, scientists were able to undertake the first explorations of the ocean depths. This second edition contains a new introduction and bibliography.

This book discusses temporal changes in six Asia-Pacific marginal seas and two west boundary currents in the Northwest Pacific. Covering time scales varying from years to decades, it provides a comprehensive review of the long-term changes in various physical variables, including sea level, sea surface temperature, water mass index, current and transport, as well as local issues such as sea ice and tidal mixing, and the processes and dynamics that govern them. The book also examines biogeochemical variables, such as nutrients, oxygen, pH, water transparency, ocean acidification, eutrophication and productivity, and explores future trends. Offering a holistic view of the changes that have occurred in the Asia-Pacific marginal seas and those that are likely to occur in the future, this book will appeal to readers from all fields of oceanography.

New Edition: Ocean Surface Waves: Their Physics and Prediction (3rd Edition)The book is an extended and updated edition of the book published in 1996 under the same title (World Scientific, ISBN 9810216866).

The book is supplemented with an extended list of relevant and extended, contemporary bibliography, subject index and author index.

This open access book serves as a reference for the key elements and their significance of Klaus Hasselmann's work on climate science and on ocean wave research, all based on a rigorous and deeply physical thinking. It summarizes the original articles (mostly from the 1970 and 1980s; some of which are hard to find nowadays) and brings them in a present-day context. From 1975 until 2000, he was (founding) Director of the Max Planck Institute of Meteorology, which he made to one of the world-leading academic institutions. He first made the issue of anthropogenic climate change accessible to analysis and prediction and later transformed climate science into a significant factor in forming public policy. The book is written by co-workers and colleagues of Klaus Hasselmann, who-many under his immediate supervision-joined him in this effort. With this background, they present the key achievements and assess the significance of these for the present state of knowledge and scientific practice.

The Biology of Particles in Aquatic Systems, Second Edition presents the latest information on particulate and dissolved matter found in aquatic habitats ranging from small streams to oceans.

Furthermore, it includes contributions on ecological problems of the biosphere.

Caustics are natural phenomena, forming light patterns in rainbows or through drinking glasses, and creating light networks at the bottom of swimming pools. Only in recent years have scientists started to artificially create simple caustics with laser light. However, these realizations have already contributed to progress in advanced imaging, lithography, and micro-manipulation. In this book, Alessandro Zannotti pioneers caustics in many ways, establishing the field of artificial caustic optics. He employs caustic design to customize high-intensity laser light. This is of great relevance for laser-based machining, sensing, microscopy, and secure communication. The author also solves a long standing problem concerning the origin of rogue waves which appear naturally in the sea and can have disastrous consequences. By means of a far-reaching optical analogy, he identifies scattering of caustics in random media as the origin of rogue waves, and shows how nonlinear light-matter interaction increases their probability.

This book provides effective statistical analyses in benthic foraminiferal communities patterns and show solutions for sea-land processes and alterations caused by climate changes and other local (and global) environmental concerns. Our goal is to provide, through these chapters, the monitoring and forecasting of environmental impacts with accurate data. We identify global regions most subject to industrial pollution, contamination and sewage, identifying potential sites prone to accumulate organic matter, which effects erosion, deposition, ocean temperature and pH changes (warming, cooling, acidification), climate and sea-level changes. Benthic habitats, specifically foraminiferal (single celled microorganisms found in the water column and sediment) contribute to our understanding of local and global climate change that effect at risk communities. Derived through the accuracy of oceanographic climate science, allow us to predict with the intention to alleviate potential loss in coastal areas, which are, the most vulnerable to ocean warming, cooling, acidification, and sea-level rise impacts. We unravel the mystery of the Environmental Impacts and Climate Change, helping communities prepare, adjust, adapt, and minimize effects or remediate loss. We show how to pinpoint the most vulnerable and specific sites for economic and social damage and loss, using foraminifera, an inexpensive and easily handled proxy valuable for monitoring coastal and marine environmental stressors. The implications of those problems and the ability to forecast patterns on land are primary issues we address by studying marine sediment of beaches, estuaries, bays and deep water worldwide. Ecology, biology, life history, and taxonomy of modern Foraminifera allows us to examine the current and historical record of environmental change effects, and predict implications for future sea-level rise, and ocean patterns. The prediction of responses of interacting systems to these problems, and development of strategies is needed to inform leadership with the knowledge and data to effectively implement policy, making this book a very informative and significant contribution for researchers and decision makers.
