This comprehensive handbook provides a global overview of ocean resources and management by focusing on critical issues relating to human development and the marine environment, their interrelationships as expressed through the uses of the sea as a resource, and the regional expression of these themes. The underlying approach is geographical, with prominence given to the biosphere, political arrangements and regional patterns - all considered to be especially crucial to the human understanding required for the use and management of the world's oceans. Part one addresses key themes in our knowledge of relationships between people and the sea on a global scale, including economic and political issues, and understanding and managing marine environments. Part two provides a systematic review of the uses of the sea, grouped into food, ocean space, materials and energy, and the sea as an environmental resource. Part three on the geography of the sea considers management strategies especially related to the state system, and regional management developments in both core economic regions and the developing periphery. The primary themes within each chapter are governance (including institutional and legal bases); policy - sets of ideas governing management; and management, both technical and general.

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.

Coastal and estuarine environments at the interface of terrestrial and marine areas are among the most productive in the world. However, since the beginning of the industrial era, these ecosystems have been subjected to strong anthropogenic pressures intensified from the second half of the 20th century, when there was a marked acceleration in the warming (climate change) of the continents, particularly at high latitudes. Coastal ecosystems are highly vulnerable to alteration of their physical, chemical and biological characteristics (marine intrusion, acidification of marine environments, changes in ecosystems, evolution and artificialization of the coastline, etc.).In contact with heavily populated areas, these environments are often the receptacle of a lot of chemical and biological pollution sources that significantly diminish their resilience. In this context of accelerated evolution and degradation of these areas important for food security of many populations around the world, it is necessary to better identify the factors of pressure and understand, at different scales of observation, their effects and impacts on the biodiversity and on the socio-eco-systems, in order to determine the degree of vulnerability of these coastal ecosystems and the risks they face. A transdisciplinary and integrated approach is required to prevent risks. Within this framework, operational coastal oceanography occupies an important place but also the implementation of a true socio-eco-system approach in order to set up an environmentally friendly development.

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.

This volume offers a broad and comprehensive examination of observational, modeling and theoretical aspects of coastal sea level science. The collection of overview articles provides up-to-date information on the causes of coastal sea level variability and change, contributes to better understanding of the influence of large-scale climate signals and open ocean processes on the coast, and addresses effects of waves, storm surges, and tides on extreme sea level and coastal flooding. Projections of long-term coastal changes and associated uncertainties are also proposed. The volume contributes to better identifying priorities for the development of an optimal and integrated (satellite and ground-based) coastal observing system and highlights present modeling and observing challenges for monitoring and predicting coastal sea level on daily to multi-decadal time scales.

The use of the trace element content of sedimentary pyrite as a proxy for the trace element composition of past oceans has recently emerged. The pyrite proxy has several potential advantages over bulk sample analysis: preservation through metamorphism; little dilution during analysis (samples are ablated not dissolved, allowing for the less abundant elements commonly held in the sulfide fraction to be investigated as proxies); accurate measurement of several elements simultaneously; the ability to screen sediments for hydrothermal overprint; and the technique can give information regarding trace element availably at multiple stages of diagenesis. Because of these multiple strengths, the pyrite trace element proxy is a valuable potential addition to the paleo-ocean chemistry tool kit.

This book presents the findings of recent theoretical and experimental studies of processes in the atmosphere, oceans and lithosphere, discussing their interactions, environmental issues, geology, problems related to human impacts on the environment, and methods of geophysical research. It particularly focuses on the geomechanical aspects of the production of hydrocarbons, including the laborious extraction of oils. Furthermore, it includes contributions on ecological problems of the biosphere.

This historical study examines a crucial phase of the relations of science and politics in the post-Civil War period: the long rivalry between the civilian Coast Survey and the military Hydrographic office, both government science agencies.

Nitrogen is an essential nutrient for life, and its sources and cycling have varied over earth history. Stable isotope ratios of nitrogen compounds (expressed as 15N, in 0/00) are preserved in the sedimentary record and track these changes, providing important insights into associated biogeochemical feedbacks. Here we review the use of nitrogen stable isotope geochemistry in unravelling the evolution of the global N cycle in deep time. We highlight difficulties with preservation, unambiguous interpretations, and local versus global effects. We end with several case studies illustrating how depositional and stratigraphic context is crucial in reliably interpreting 15N records in ancient marine sediments, both in ancient anoxic (Archean) and more recent well oxygenated (Phanerozoic) environments.

The attraction of selenium isotopes as a paleoenvironmental tracer lies in the high redox potential of selenium oxyanions (SeIV and SeVI), the dominant species in the modern ocean. The largest isotopic fractionations occur during oxyanion reduction, which makes selenium isotopes a sensitive proxy for the redox evolution of our planet. As a case study we review existing data from the Neoarchean and Paleoproterozoic, which show that significant isotopic fractionations are absent until 2.5 Ga, and prolonged isotopic deviations only appear around 2.3 Ga. Selenium isotopes have thus begun to reveal complex spatiotemporal redox patterns not reflected in other proxies.

Vanadium isotope ratios (51V/50V) have potential to provide information about changes in past ocean oxygen contents. In particular, V isotopes may find utility in tracing variations at non-zero oxygen concentrations because the redox couple that controls V elemental and isotopic abundances in seawater (vanadate-vanadyl) appears to operate around 10M O2. This characteristic sets V isotopes apart from many other metal isotope redox proxies that require more reducing conditions to register significant changes in their isotope budgets. The oxygen abundance sensitivity range of V isotopes suggests that this paleoproxy could be particularly useful in tracing marine oxygenation changes throughout the Phanerozoic and potentially beyond.

This book is a collection of extended papers based on presentations given during the ICEC 2018 conference, held in Caen, France, in August 2018. It explores both the limitations and advantages of current models, and highlights the latest developments concerning new numerical schemes, high-performance computing, multi-physics and multi-scale methods, and better interaction with field or scale model data. Accordingly, it addresses the interests of practitioners, stakeholders, researchers, and engineers active in this field.

In one form or another, iron speciation has had a long history as a paleoredox proxy. The technique has been refined considerably over the years, and the most recent scheme is unique in its potential to distinguish three major oceanic redox states - oxygenated, ferruginous and euxinic. This Element covers the theory behind the proxy, methods involved in applying the technique, and potential complications in interpreting Fe speciation data. A series of case studies are also provided, which highlight how more advanced consideration of the data, often in concert with other techniques, can provide unprecedented insight into the redox state of ancient oceans.

Surface, intermediate, and deep-water processes and their interaction in time and space drive the major ocean circulation of the Mediterranean Sea. All major forcing mechanisms, such as surface wind forcing, buoyancy fluxes, lateral mass exchange, and deep convection determining the global oceanic circulation are present in this body of water. Deep and intermediate water masses are formed in different areas of the ocean layers and they drive the Mediterranean thermohaline cell, which further shows important analogies with the global ocean conveyor belt. "The Mediterranean Sea: Temporal Variability and Spatial Patterns "is a comprehensive volume that investigates the temporal and spatial variability patterns in the ocean basin.

Volume highlights include: Discussions of state-of-the-art physical and biogeochemical properties of the Mediterranean SeaMultiple physical ocean circulation processes, both in time and spatial scales (basin, sub-basin, and mesoscale)How different regional phenomena in the sea influence the biogeochemistry of the basin and the ocean dynamicsSpatio-temporal variability of the surface circulation in the western MediterraneanDeep-water variability and inter-basin interactions in the eastern Mediterranean SeaUnderstanding the link between global ocean circulation patterns and the global climate

"The Mediterranean Sea "will be a valuable resource for geoscientists, oceanographers, and meteorologists.

The stable chromium (Cr) isotope system has emerged over the past decade as a new tool to track changes in the amount of oxygen in earth's ocean-atmosphere system. Much of the initial foundation for using Cr isotopes ( 53Cr) as a paleoredox proxy has required recent revision. However, the basic idea behind using Cr isotopes as redox tracers is straightforward-the largest isotope fractionations are redox-dependent and occur during partial reduction of Cr(VI). As such, Cr isotopic signatures can provide novel insights into Cr redox cycling in both marine and terrestrial settings. Critically, the Cr isotope system-unlike many other trace metal proxies-can respond to short-term redox perturbations (e.g., on timescales characteristic of Pleistocene glacial-interglacial cycles). The Cr isotope system can also be used to probe the earth's long-term atmospheric oxygenation, pointing towards low but likely dynamic oxygen levels for the majority of Earth's history.

Personal, anecdotal, and highly engaging, "Watching Giants" opens a window on a world that seems quite like our own, yet is so different that understanding it pushes the very limits of our senses. Elin Kelsey's colorful first-person account, drawing from her rich, often humorous, everyday experiences as a mother, a woman, and a scientist, takes us to the incredibly productive waters of the Gulf of California and beyond, to oceans around the world. Kelsey brings us along as she talks to leading cetacean researchers and marine ecologists about their intriguing discoveries. We encounter humpback whales that build nets from bubbles, gain a disturbing maternal perspective on the dolphin-tuna issue, uncover intimate details about whale sex, and contemplate the meaning of the complex social networks that exist in the seas. What emerges alongside these fascinating snapshots of whale culture is a dizzying sense of the tremendous speed with which we are changing the oceans' ecosystems - through overfishing, noise pollution, even real estate development. "Watching Giants" introduces a world of immense interconnectivity and beauty - one that is now facing imminent peril.

This edited volume addresses the impacts of climate change on Pacific islands, and presents databases and indexes for assessing and adapting to island vulnerabilities. By analyzing susceptibility variables, developing comprehensive vulnerability indexes, and applying GIS techniques, the book's authors demonstrate the particular issues presented by climate change in the islands of the Pacific region, and how these issues may be managed to preserve and improve biodiversity and human livelihoods. The book first introduces the issues specific to island communities, such as high emissions impacts, and discusses the importance of the lithological traits of Pacific islands and how these physical factors relate to climate change impacts. From here, the book aims to analyze the various vulnerabilities of different island sectors, and to formulate a susceptibility index from these variables to be used by government and planning agencies for relief prioritization. Such variables include tropical cyclones, built infrastructures, proximity to coastal areas, agriculture, fisheries and marine resources, groundwater availability, biodiversity, and economic impacts on industries such as tourism. Through the categorization and indexing of these variables, human and physical adaptation measures are proposed, and support solutions are offered to aid the inhabitants of affected island countries. This book is intended for policy makers, academics, and climate change researchers, particularly those dealing with climate change impacts on small islands.

This book reviews all aspects of the field, from low-temperature to high-temperature processes, biological processes, and cosmochemical processes. It provides a detailed history and state-of-the art summary about analytical methods to determine Fe-isotope ratios and discusses analytical and sample prospects.

International Marine Mammal Law is a comprehensive, introductory volume on the legal regimes governing the conservation and utilisation of marine mammals. Written as a textbook, it provides basic overviews of international conservation law, which enable the reader to understand the greater implications of governance of a specific group of species. Paired with biological information on some marine mammal species, the international regimes for whales, seals and polar bears are explored - either as part of global regimes of international environmental governance or as regimes that were specifically designed for them. The book concludes with outlooks on the future of international marine mammal law, particularly in light of Japan's withdrawal from the International Convention for the Regulation of Whaling in July 2019.

Reconstruction of ocean paleoproductivity and paleochemistry is paramount to understanding global biogeochemical cycles such as the carbon, oxygen and sulfur cycles and the responses of these cycles to changes in climate and tectonics. Paleo-reconstruction involves the application of various tracers that record seawater compositions, which in turn may be used to infer oceanic processes. Several important tracers are incorporated into pelagic barite, an authigenic mineral that forms in the water column. Here we summarize the utility of pelagic barite for the reconstruction of export production and as a recorder of seawater S, O, Sr, Ca and Ba.

Full of mystery and danger, the deep sea has long been a symbol of the great unknown. In this dramatic and thrilling account, acclaimed biologist and deep sea diver Bill Streever shows us the incredible adventures happening in earth's almost incomprehensibly vast oceans. From the bottom of the Challenger Deep (the deepest known point in the ocean), to the earliest submarine technologies and exploratory deep dives, into the world of competitive breath-hold divers and the riskiest thrill seekers on the planet, In Oceans Deep is a human history, and a natural history of the earth's last true frontier. With treasure ship wrecks, the echoing pings of trapped submariners, and the vast expanse of otherworldly robots and oil rigs that dominate the oceanic landscape, In Oceans Deep is a rare and fascinating trip to the wild, strange, night-dark place that lies beneath the waves.

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 focuses on prehistoric East Asian maritime cultures that pre-dated the Maritime Silk Road, the "Four Seas" and "Four Oceans" navigation system recorded in historical documents of ancient China. Origins of the Maritime Silk Road can be traced to prosperous Neolithic and Metal Age maritime-oriented cultures dispersed along the coastlines of prehistoric China and Southeast Asia. The topics explored here include Neolithisation and the development of prehistoric maritime cultures during the Neolithic and early Metal Age; the expansion and interaction of these cultures along coastlines and across straits; the "two-layer" hypothesis for explaining genetic and cultural diversity in south China and Southeast Asia; prehistoric seafaring and early sea routes; the paleogeography and vegetation history of coastal regions; Neolithic maritime livelihoods based on hunting/fishing/foraging adaptations; rice and millet cultivation and their dispersal along the coast and across the open sea; and interaction between farmers and maritime-oriented hunter/fisher/foragers. In addition, a series of case studies enhances understanding of the development of prehistoric navigation and the origin of the Maritime Silk Road in the Asia-Pacific region.

This book presents recent results of collaborative studies in geophysics and ecology, focusing on the relationship between the physical environment and the distribution of the marine coastal ecosystems. The study area, the Sakiyamawan-Amitoriwan nature conservation area in Iriomote Island of Japan, is the only oceanic nature conservation area in the country. The area has no access roads, and the bay perimeter is uninhabited; therefore, it preserves the natural environment with very little human impact. In addition, it has various environmental gradients such as topography and inflows from rivers with mangrove forests which affect the distribution of marine coastal ecosystems such as those containing reef-building corals, sea grasses, and hermit crabs. For these reasons, the area is one of the best places for the study of the relationship between the physical environment and the distribution of the marine coastal ecosystems, a relationship that is important for their conservation but has not been investigated fully. This book is aimed at students and researchers in the fields of oceanography and marine coastal ecology as well as general readers who are interested in coral reefs, diving, and nature conservation.
