Between extremes of climate farther north and south, the 38th North
parallel line marks a temperate, middle latitude where human
societies have thrived since the beginning of civilization. It
divides North and South Korea, passes through Athens and San
Francisco, and bisects Mono Lake in the eastern Sierra Nevada,
where authors David and Janet Carle make their home. Former park
rangers, the authors set out on an around-the-world journey in
search of water-related environmental and cultural intersections
along the 38th parallel. This book is a chronicle of their
adventures as they meet people confronting challenges in water
supply, pollution, wetlands loss, and habitat protection. At the
heart of the narrative are the riveting stories of the passionate
individuals--scientists, educators, and local activists--who are
struggling to preserve some of the world's most amazing, yet
threatened, landscapes.
A counterintuitive and compelling argument that existing laws already protect the entirety of our oceans-and a call to understand and enforce those protections. The world's oceans face multiple threats: the effects of climate change, pollution, overfishing, plastic waste, and more. Confronted with the immensity of these challenges and of the oceans themselves, we might wonder what more can be done to stop their decline and better protect the sea and marine life. Such widespread environmental threats call for a simple but significant shift in reasoning to bring about long-overdue, elemental change in the way we use ocean resources. In Future Sea, ocean advocate and marine-policy researcher Deborah Rowan Wright provides the tools for that shift. Questioning the underlying philosophy of established ocean conservation approaches, Rowan Wright lays out a radical alternative: a bold and far-reaching strategy of 100 percent ocean protection that would put an end to destructive industrial activities, better safeguard marine biodiversity, and enable ocean wildlife to return and thrive along coasts and in seas around the globe. Future Sea is essentially concerned with the solutions and not the problems. Rowan Wright shines a light on existing international laws intended to keep marine environments safe that could underpin this new strategy. She gathers inspiring stories of communities and countries using ocean resources wisely, as well as of successful conservation projects, to build up a cautiously optimistic picture of the future for our oceans-counteracting all-too-prevalent reports of doom and gloom. A passionate, sweeping, and personal account, Future Sea not only argues for systemic change in how we manage what we do in the sea but also describes steps that anyone, from children to political leaders (or indeed, any reader of the book), can take toward safeguarding the oceans and their extraordinary wildlife.
Magnesium is a major constituent in silicate and carbonate minerals, the hydrosphere and the biosphere. Magnesium is constantly cycled between these reservoirs. Since each of the major planetary reservoirs of magnesium have different magnesium isotope ratios, there is scope to use magnesium isotope ratios to trace 1) the processes that cycle Magnesium at a spatial scales from the entire planet to microscopic and 2) the relative fluxes between these reservoirs. This review summarises some of the key motivations, successes and challenges facing the use of magnesium isotopes to construct a budget of seawater magnesium, present and past.
Coastal regions around the world have become increasingly crowded, intensively developed, and severely exploited. Hundreds of millions of people living in these low-lying areas are subject to short-term coastal hazards such as cyclones, hurricanes, and destruction due to El Nino, and are also exposed to the long-term threat of global sea-level rise. These massive concentrations of people expose often-fragile coastal environments to the runoff and pollution from municipal, industrial, and agricultural sources as well as the impacts of resource exploitation and a wide range of other human impacts. Can environmental impacts be reduced or mitigated and can coastal regions adapt to natural hazards? Coasts in Crisis is a comprehensive assessment of the impacts that the human population is having on the coastal zone globally and the diverse ways in which coastal hazards impact human settlement and development. Gary Griggs provides a concise overview of the individual hazards, risks, and issues threatening the coastal zone.
Lithium isotopes are a relatively novel tracer of present and past silicate weathering processes. Given that silicate weathering is the primary long-term method by which CO2 is removed from the atmosphere, Li isotope research is going through an exciting phase. We show the weathering processes that fractionate dissolved and sedimentary Li isotope ratios, focusing on weathering intensity and clay formation. We then discuss the carbonate and silicate archive potential of past seawater 7Li. These archives have been used to examine Li isotope changes across both short and long timescales. The former can demonstrate the rates at which the climate is stabilised from perturbations via weathering, a fundamental piece of the puzzle of the long-term carbon cycle.

As we discover more about the role of the ocean in global changes and identify the effects of global change on the ocean, understanding its chemical composition and processes becomes increasingly paramount. However, understanding these processes requires a wide range of measurements in the vast ocean, from the sea surface to deep-ocean trenches, from the tropics to the poles. Practical Guidelines for the Analysis of Seawater provides a common analytical basis for generating quality-assured and reliable data on chemical parameters in the ocean. A source of practical know-how, the book covers sampling and storage, analytical methodology, and guidelines and procedures for quality assurance. It presents analytical methods with the step-by-step procedures that help practitioners implement these methods successfully into the laboratory, making them instantly applicable without consulting further literature. The book also contains essential information for developing or improving quality control and quality assurance programs in the laboratory. It includes the availability and measurement of standard reference materials, blank estimation and correction, control of recoveries, and statistical evaluation of quality assurance data. Analytical chemistry is a very active and fast moving area. Despite the development of innovative new analytical techniques for chemical trace element research, obtaining reliable data at ultra-trace levels remains a formidable challenge. A complete and practical guide, this book delineates proven methods that consistently yield reproducible data in routine work.
Have you ever wondered where waves come from? What makes every one different, why some peel nicely and others just close out? Why, some days, waves come in sets of six and others in sets of three, and what factors affect the behavior of a surfing break? If you have, this book is for you. Now in its third edition, Surf Science is the first book to talk in depth about the science of waves from a surfer's point of view. It fills the gap between surfing books and waves textbooks and will help you learn how to predict surf. You don't need a scientific background to read it--just curiosity and a fascination for waves.
This book explores the types of conflicts that occur over marine and coastal resources, the underlying causes, and attempts to prevent them. Despite the emergence of various marine and coastal governance approaches to address the effects of human activities within the marine environment, conflict continues. In this book, the author outlines the reasons conflicts can, and do, arise in the marine and coastal environment. Drawing on case studies from both the northern and southern hemispheres, the book takes a broad view of how we interact with our environment, of how and why conflict is perpetuated as a political and cultural phenomenon, and how this varies or remains constant across space and place. The case studies explore not only the underlying perceptions and needs of those involved in marine and coastal conflict and the types of conflicts that arise in oceanic and coastal areas, but also the underpinning reasons for these conflicts. Marine and coastal resource conflicts have the potential to derail conservation efforts and blue growth policies, as well as the United Nations Sustainable Development Goals. Thus, it is imperative we understand the drivers and exacerbating factors of marine and coastal conflict. Arguing that there is an urgent need for renewed thinking and focus on conflict prevention, the author develops a theory of marine and coastal conflict which allows us to understand those factors and the means to help prevent such conflicts arising in the first place. This book will be of interest to students and researchers of coastal and marine science and environmental management as well as those working in the field of marine resource management, including coastal zone managers and fisheries managers.
This volume discusses geological, biological and sustainability aspects of coastal, estuary and lake environments. It offers a comprehensive understanding of biotic, physico-chemical, sedimentological and socio-environmental factors associated with the sustainable development of these environments in areas vulnerable to climate change and other anthropogenic activities. The book is divided into several main sections, covering the geological and biological processes and dynamics of these environments, water quality and hydrological modeling, sediment characteristics, bio-indicators and ecological analysis, climate change impacts, geospatial applications, and sustainable development practices and scenarios. The book aims to be a useful resource for academics, scientists, coastal and marine practitioners, meteorologists, environmental consultants and computing experts working in the areas of earth and ocean sciences.
Anthropogenic carbon dioxide emissions do not only warm our planet but also acidify our oceans. It is currently unclear to which degree Earth's climate and marine life will be impacted by these changes but information from Earth history, particularly the geochemical signals of past environmental changes stored in the fossil remains of marine organisms, can help us predict possible future changes. This book aims to be a primer for scientists who seek to apply boron proxies in marine carbonates to estimate past seawater carbonate chemistry and atmospheric pCO2. Boron proxies ( 11B and B/Ca) were introduced nearly three decades ago, with subsequent strides being made in understanding their mechanistic functioning. This text reviews current knowledge about the aqueous systematics, the inorganic and biological controls on boron isotope fractionation and incorporation into marine carbonates, as well as the analytical techniques for measurement of boron proxies. Laboratory and field calibrations of the boron proxies are summarized, and similarities between modern calibrations are explored to suggest estimates for proxy sensitivities in marine calcifiers that are now extinct. Example applications illustrate the potential for reconstructing paleo-atmospheric pCO2 from boron isotopes. Also explored are the sensitivity of paleo-ocean acidity and pCO2 reconstructions to boron isotope proxy systematics that are currently less well understood, including the elemental and boron isotopic composition of seawater through time, seawater alkalinity, temperature and salinity, and their collective impact on the uncertainty of paleo-reconstructions. The B/Ca proxy is based on the same mechanistic principles as the boron isotope proxy, but empirical calibrations suggest seawater pH is not the only controlling factor. B/Ca therefore has the potential to provide a second carbonate parameter that could be paired with 11B to fully constrain the ocean carbonate system, but the associated uncertainties are large. This text reviews and examines what is currently known about the B/Ca proxy systematics. As more scientists embark on characterizing past ocean acidity and atmospheric pCO2, Boron in Paleoceanography and Paleoclimatology provides a resource to introduce geoscientists to the opportunities and complications of boron proxies, including potential avenues to further refine them.

Instabilities are present in all natural fluids from rivers to atmospheres. This book considers the physical processes that generate instability. Part I describes the normal mode instabilities most important in geophysical applications, including convection, shear instability and baroclinic instability. Classical analytical approaches are covered, while also emphasising numerical methods, mechanisms such as internal wave resonance, and simple `rules of thumb' that permit assessment of instability quickly and intuitively. Part II introduces the cutting edge: nonmodal instabilities, the relationship between instability and turbulence, self-organised criticality, and advanced numerical techniques. Featuring numerous exercises and projects, the book is ideal for advanced students and researchers wishing to understand flow instability and apply it to their own research. It can be used to teach courses in oceanography, atmospheric science, coastal engineering, applied mathematics and environmental science. Exercise solutions and MATLAB (R) examples are provided online. Also available as Open Access on Cambridge Core.
Combining rigorous theory with practical application, this book provides a unified and detailed account of the fundamental equations governing atmospheric and oceanic fluid flow on which global, quantitative models of weather and climate prediction are founded. It lays the foundation for more accurate models by making fewer approximations and imposing dynamical and thermodynamical consistency, moving beyond the assumption that the Earth is perfectly spherical. A general set of equations is developed in a standard notation with clearly stated assumptions, limitations, and important properties. Some exact, non-linear solutions are developed to promote further understanding and for testing purposes. This book contains a thorough consideration of the fundamental equations for atmospheric and oceanic models, and is therefore invaluable to both theoreticians and numerical modellers. It also stands as an accessible source for reference purposes.

'Like Sir David Attenborough, he has the rare ability to be an excellent communicator and has written an engaging book sprinkled with mind-blowing facts about the deep oceans' - Daily Express 'A new informed perspective on the wide, watery world we inhabit' - Coast magazine 'Book of the month' 'The gripping story of how ocean science has advanced in recent years is captivatingly told by Jon Copley in this introduction to the deep ocean' - China Dialogue 'Deftly conjures the wonders of a bathynaut's world' - Nature It is often said that we know more about space than we do our own oceans, but is that really the case? Or do we in fact know a great deal more about the oceans than many people realise. The wellbeing of our oceans and the life contained within and around them has never been more important. But to truly understand the vital role they play, we need to first understand how the oceans work, how we explore them and learn about the mysteries they hold, and what our effect is on them. Between these pages is everything you need to know about our oceans, explained in 25 questions. Combining untold history of ocean exploration and personal account of what it's like to be a 'bathynaut' diving in a mini-submarine, Ask an Ocean Explorer brings to light weird and wonderful deep-sea creatures and how the oceans and their future is connected to our everyday lives.
The manufacture of plastic as well as its indiscriminate disposal and destruction by incineration pollutes atmospheric, terrestrial, and aquatic ecosystems. Synthetic plastics do not break down; they accumulate in the environment as macro-, micro-, and nanoplastics. These particulate plastics are a major source of pollutants in soil and marine ecosystems. Particulate Plastics in Terrestrial and Aquatic Environments provides a fundamental understanding of the sources of these plastics and the threats they pose to the environment. The book demonstrates the ecotoxicity of particulate plastics using case studies and offers management practices to mitigate particulate plastic contamination in the environment. Features * Describes physical and chemical properties of particulate plastics in terrestrial and aquatic ecosystems * Presents information on characteristics of particulate plastics as impacted by weathering processes * Provides numerous approaches for managing particulate plastic contamination * Identifies sources of particulate plastics in the environment; distribution and characteristics of particulate plastics; and management strategies of particulate plastics Written by a global team of scientists, this book is for researchers in the fields of environmental safety and waste management or individuals interested in the impact of particulate plastics on environmental health.
This book provides a cross-sectoral, multi-disciplinary assessment of different problems associated with estuarine acidification with special thrust on mangrove dominated Indian Sundarban estuaries. The arms of ocean acidification have extended to coastal and estuarine waters, where a wide spectrum of biodiversity thrives with unique adaptation extending several ecosystem services. Impact of acidification in these areas is a matter of concern as acidification potentially has more immediate effects on the health of estuaries and inshore regions as well as regional economies. Ground zero data collected for more than three decades have made the book stand on a strong base.
Although the United States and other affluent nations havemore than an adequate food supply, other nations daily facethe specter of starvation. The world now has a critical population/food dilemma of potentially major proportions. Production fromthe sea and the land is not keeping pace with a world populationthat is doubling every thirty-five years. Unless this age-oldMalthusian problem is solved, millions face starvation and ultimatelydeath.The situation has stimulated substantial international interestin the sea as a source of food and raw materials. The potentialof the sea-not as a panacea, but as an important source of proteinto augment the world's food supplies and thereby as a meansof mitigating the crises we face-is a continuing theme throughoutthis book. At present, fish provide approximately 9 percentof the world's protein. Fish are sought not only for food butalso for recreation and pleasure. What forces determine the presentsupply and demand for fishery products? More important,what steps are needed to utilize the full potential of the sea asa source of food and recreation? This book explores these forcesand thus provides an insight into food potential from the sea.

How Japanese coastal residents and transnational conservationists collaborated to foster relationships between humans and sea life Drawing the Sea Near opens a new window to our understanding of transnational conservation by investigating projects in Okinawa shaped by a "conservation-near" approach-which draws on the senses, the body, and memory to collapse the distance between people and their surroundings and to foster collaboration and equity between coastal residents and transnational conservation organizations. This approach contrasts with the traditional Western "conservation-far" model premised on the separation of humans from the environment. Based on twenty months of participant observation and interviews, this richly detailed, engagingly written ethnography focuses on Okinawa's coral reefs to explore an unusually inclusive, experiential, and socially just approach to conservation. In doing so, C. Anne Claus challenges orthodox assumptions about nature, wilderness, and the future of environmentalism within transnational organizations. She provides a compelling look at how transnational conservation organizations-in this case a field office of the World Wide Fund for Nature in Okinawa-negotiate institutional expectations for conservation with localized approaches to caring for ocean life. In pursuing how particular projects off the coast of Japan unfolded, Drawing the Sea Near illuminates the real challenges and possibilities of work within the multifaceted transnational structures of global conservation organizations. Uniquely, it focuses on the conservationists themselves: why and how has their approach to project work changed, and how have they themselves been transformed in the process?
