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.

The Bestselling Classic Updated for Surfers, Sailors, Oceanographers, Climate Activists, and Those Who Love the Sea First published in 1963 and updated in 1979, this classic was an essential handbook for anyone who studies, surfs, protects, or is fascinated by the ocean. The original author, Willard Bascom, was a master of the subject and included a wealth of information, based on theory and statistics, but also anecdotal observation and personal experience. It brought to the general public understanding of the awesome and complex power of the waves. This revision from Kim McCoy adds recent facts and anecdotes to update the book's relevance in the time of climate change. One of the most significant effects of global warming will be sea-level rise. What will this mean to waves and beaches, and what effects are we already seeing? New text and photos cover events such as the Indian Ocean tsunami of 2004, Hurricane Katrina flooding of 2005, and the 2011 earthquake and resulting devastation in Fukishima. As well as students, surfers, and the general public, this updated edition of a beloved classic is an essential handbook for climate scientists and ocean activists, providing clear explanations and detailed resources for the constant battle to preserve the shore.

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.

A pioneering marine biologist takes us down into the deep ocean in this 'thrilling blend of hard science and high adventure' (New York Times) Edith Widder grew up determined to become a marine biologist. But after complications from a surgery during college caused her to go temporarily blind, she became fascinated by light as well as the power of optimism. Below the Edge of Darkness explores the depths of the planet's oceans as Widder seeks to understand bioluminescence, one of the most important and widely used forms of communication in nature. In the process, she reveals hidden worlds and a dazzling menagerie of behaviours and animals. Alongside Widder, we experience life-and-death equipment malfunctions and witness breakthroughs in technology and understanding, all of it set against a growing awareness of the deteriorating health of our largest and least understood ecosystem. 'A vivid account of ocean life' ROBIN MCKIE, GUARDIAN BOOK OF THE DAY 'Edie's story is one of hardscrabble optimism, two-fisted exploration and groundbreaking research.

Originally published in 1990 Tropical Resources presents in-depth coverage of the extremely diverse tropical environments, the resources to be found within the region and their production, and ecological management. The book discusses economic geography and ways of utilizing available resources, including those of tropical forests, wildlife, tidal wetlands and the sea. The book also include chapters on the development and land use of protected areas, the ecological aspects of pasture resources; and the impacts of economic development and population damage. In addition, studies are offered on tropical soils, including their distribution properties and management and the ecological processes at work in tropical forests. For geographers, economists and policymakers, the book provides a wealth of information on tropical resources and their potential development.

Between 1949 and 1955, the State Department pushed for an international fisheries policy grounded in maximum sustainable yield (MSY). The concept is based on a confidence that scientists can predict, theoretically, the largest catch that can be taken from a species' stock over an indefinite period. And while it was modified in 1996 with passage of the Sustained Fisheries Act, MSY is still at the heart of modern American fisheries management. As fish populations continue to crash, however, it is clear that MSY is itself not sustainable. Indeed, the concept has been widely criticized by scientists for ignoring several key factors in fisheries management and has led to the devastating collapse of many fisheries. Carmel Finley reveals that the fallibility of MSY lies at its very inception--as a tool of government rather than science. The foundational doctrine of MSY emerged at a time when the US government was using science to promote and transfer Western knowledge and technology, and to ensure that American ships and planes would have free passage through the world's seas and skies. Finley charts the history of US fisheries science using MSY as her focus, and in particular its application to halibut, tuna, and salmon fisheries. Fish populations the world over are threatened, and All the Fish in the Sea helps to sound warnings of the effect of any management policies divested from science itself.

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.

Seawater desalination is a rapidly growing coastal industry that is increasingly threatened by algal blooms. Depending on the severity of algal blooms, desalination systems may be forced to shut down because of clogging and/or poor feed water quality. To maintain stable operation and provide good feed water quality to seawater reverse osmosis (SWRO) systems, ultrafiltration (UF) pre-treatment is proposed. This research focused on assessing the ability of UF and other pre-treatment technologies to reduce biofouling in SWRO systems. An improved method to measure bacterial regrowth potential (BRP) was developed and applied at laboratory, pilot and full scale to assess the ability of conventional UF (150 kDa) and tight UF (10 kDa) alone and in combination with a phosphate adsorbent to reduce regrowth potential and delay the onset of biofouling in SWRO. The improved bacterial regrowth potential method employs a natural consortium of marine bacteria as inoculum and flow cytometry. The limit of detection of the BRP method was lowered to 43,000 +/- 12,000 cells/mL, which is equivalent to 9.3 +/- 2.6 g-Cglucose/L. The reduction in bacterial regrowth potential after tight UF (10 kDa) was 3 to 4 times higher than with conventional UF (150 kDa). It was further reduced after the application of a phosphate adsorbent, independent of pore size of the UF membrane. Pilot studies demonstrated that the application of tight UF (10 kDa) coupled with a phosphate adsorbent consistently lowered the bacterial regrowth potential and no feed channel pressure drop increase was observed in membrane fouling simulators (MFS) over a period of 21 days. The study also showed that non-backwashable fouling of UF membranes varied strongly with the type of algal species and the algal organic matter (AOM) they release. The presence of polysaccharide (stretching -OH) and sugar ester groups (stretching S=O) was the main cause of non-backwashable fouling. In conclusion, this study showed that an improved BRP method is suitable for the assessment of SWRO pre-treatment systems and it can be a useful tool to develop potential strategies to mitigate biofouling and improve the sustainability of SWRO systems.

Australia and Canada have been at the forefront of efforts to operationalize integrated oceans and coastal management. Throughout the 1990s both countries devoted considerable effort to developing strategies to give effect to international ocean management obligations.

This key book focuses on principles of marine environmental conservation and management, maritime regulation and enforcement, and regional maritime planning and implementation. With contributions from respected scholars, this informative book collectively assesses the obligations, compliance, implementation and trends in international ocean law, particularly in giving effect to an Oceans Policy, regional maritime planning, international oceans governance, and maritime security. This book will be of interest to all academics involved with maritime studies and international law.

The Indian Ocean tsunami of December 2004 is considered to have been one of the worst natural disasters in history, affecting twelve countries, from Indonesia to Somalia. 175,000 people are believed to have lost their lives, almost 50,000 were registered as missing and 1.7 million people were displaced. As well as this horrendous toll on human life, the tsunami destroyed property worth billions of dollars and ruined many local economies. Based on their experience and analysis of this tsunami, the authors have developed methodologies for predicting and preparing for tsunamis. A basis is provided for a cost-effective warning and preparedness strategy, drawing on the example of existing systems used in earthquake disaster management and tidal wave warning, from genesis to impact. The book comprehensively addresses the fundamentals of tsunami science, identifying potential areas where tsunamis might be generated, predicting the anticipated course of tsunamis and considering how the geophysical, ecological and socioeconomic location of a community may determine the severity of tsunami damage. The authors suggest how precursors can be used to enhance the advance warning time, how tsunamis can be detected at the time of their occurrence, and the manner in which warnings should be communicated to the populations likely to be affected. Finally, improvement in eco-sociological resilience through the application of dual-use technologies is identified as a pivotal aid in allowing coastal communities to be better prepared. The book will be of interest to a global audience of professionals and academics active in seismology, ocean science, meteorology, coastal management, earthquake engineering and disaster management.

Ever-increasing interest in oceanography and marine biology and its relevance to global environmental issues creates a demand for authoritative reviews summarizing the results of recent research. Oceanography and Marine Biology: An Annual Review has answered this demand since its founding by the late Harold Barnes more than forty years ago.

The volumes maintain a unified perspective on the marine sciences. Physical, chemical, and biological aspects of marine science are dealt with by experts actively engaged in these fields. This essential reference text for researchers and students in all fields of marine science finds a place in libraries of marine stations and institutes, as well as universities. It consistently ranks among the highest in impact factors for the marine biology category of the citation indices compiled by the Institute for Scientific Information. Volume 43 contains analysis on cold seep sediments, unburnt coal in the marine environment, biofiltration and biofouling on artificial structures in Europe, ecology of rafting in marine ecosystems, effects of globalisation in marine environments, and much more.

Rip currents are among the most dangerous coastal hazards for the bathing public, and contribute to the highest portion of beach rescues all over the world. In order to help life guards in planning and preparing rescue resources so that casualties can be minimized, information about where and when rip currents may occur is needed. This can be provided by a predictive tool which combines meteorological forecasts, hydrodynamic models and remote-sensed observations. In this thesis, a methodology which can provide rip current forecasts for swimmer safety is developed and tested for Egmond aan Zee beach in the Netherlands. The approach uses the numerical model system CoSMoS, combined with daily estimates of nearshore-scale bathymetry obtained from a system called cBathy, which infers depths by estimating wave celerities from video imaging. Furthermore, in order to gain more knowledge on occurrences of rips at Egmond beach, a numerical study on the kinematics of rip currents and the safety implications for swimmers is presented as well. Coupling the video bathymetry estimates with CoSMoS in forecast mode shows that dangerous rips were correctly predicted. This thesis demonstrates the potential application of the proposed system for providing rip current forecasts at Egmond aan Zee.

Optical Remote Sensing is one of the main technologies used in sea surface monitoring. Optical Remote Sensing of Ocean Hydrodynamics investigates and demonstrates capabilities of optical remote sensing technology for enhanced observations and detection of ocean environments. It provides extensive knowledge of physical principles and capabilities of optical observations of the oceans at high spatial resolution, 1-4m, and on the observations of surface wave hydrodynamic processes. It also describes the implementation of spectral-statistical and fusion algorithms for analyses of multispectral optical databases and establishes physics-based criteria for detection of complex wave phenomena and hydrodynamic disturbances including assessment and management of optical databases. This book explains the physical principles of high-resolution optical imagery of the ocean surface, discusses for the first time the capabilities of observing hydrodynamic processes and events, and emphasizes the integration of optical measurements and enhanced data analysis. It also covers both the assessment and the interpretation of dynamic multispectral optical databases and includes applications for advanced studies and nonacoustic detection. This book is an invaluable resource for researches, industry professionals, engineers, and students working on cross-disciplinary problems in ocean hydrodynamics, optical remote sensing of the ocean and sea surface remote sensing. Readers in the fields of geosciences and remote sensing, applied physics, oceanography, satellite observation technology, and optical engineering will learn the theory and practice of optical interactions with the ocean.

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.

The sea has been the site of radical changes in human lives and national histories. It has been an agent of colonial oppression but also of indigenous resistance, a site of loss, dispersal and enforced migration but also of new forms of solidarity and affective kinship. Sea Changes re-evaluates the view that history happens mainly on dry land and makes the case for a creative reinterpretation of the role of the sea: not merely as a passage from one country to the next, but a historical site deserving close study.

Throughout history, dominance of the Indian Ocean has been a critical factor in defining a nation's supremacy and power. It is well known that it played a major part in the success of the Portugese nation at the start of the sixteenth century. In this concise survey, Milo Kearney shows how the trading and imperial expansion offered by the Indian Ocean were exploited by many leading powers from the third millennium B.C. to the very recent past.
The nations included range from the ancient Egyptians of the new Kingdom to the Han Chinese and, later, from the Moghul to the British Empire. Milo Kearney goes on to show what a critical territory the Indian Ocean was during the Cold War because of its rich supply for oil.
The history of the Indian Ocean provides a snapshot of many of the key issues in world history, such as colonialism, trade and spread of cultures and religions. It is important reading for all students of world history.

This unique book introduces the biological and ecological basis of the production process in water, and the biology of cultured species. It bridges the gap between research data and aquaculture techniques, and covers problems arising in aquaculture production, such as filtering molluscs. It also introduced modern aspects of oceanography that are important for understanding the production process. The book starts with a section dedicated to the production of living material and matter in the aquatic environment. It then goes on to explore in detail the biological basis of mollusc, crustacean and fish cultures, and the reproduction and nutrition of bivalve molluscs. Also discussed are the intensive and extensive aquaculture producing processes in fresh and marine waters, and finally the pathology reared animals. Up-to-date data are provided and explained to the student using graphs and copious illustrations. The work is especially orientated toward the student reader and provides a comprehensive and authoritative text on the subject.

The management of common pool resources and publicly-owned areas is fraught with difficulty. This book explores the long, complex, and frequently contentious history of public lands management in the United States in order to draw lessons for the emerging field of marine spatial planning (MSP). The author first establishes that these two seemingly different settings are in fact remarkably similar, drawing on established theories of policy analysis. The work then examines the management of US National Forests over the past 120 years, including three place-based case studies, to discover recurring themes. The analysis shows how different management approaches evolved over time in response to changing laws and cultural norms, producing outcomes favored by different constituencies. This history also reveals the ambiguities and contradictions inherent in multiple-use management of any public space. Next, the book analyzes recent efforts to advance MSP, both in the US and globally, showing how they mirror past experiences in National Forest management, including similar disagreements among stakeholders. In conclusion the author suggests how those within ocean-related sectors - government, academia, industry, and environmental groups - might achieve their individual and collective goals more effectively based on lessons from the public lands setting.

The seas and oceans are currently taking centre stage in academic study and public consciousness. From the plastics littering our seas, to the role of climate change on ocean currents from unequal access of marine resources to the treacherous experiences of seafarers who keep our global economy afloat; now is a crucial time to examine how we live with the sea. This ambitious book brings together an interdisciplinary and international cohort of contributors from within and beyond academia. It offers a range and diversity of insights unlike previous collections. An 'oceanic turn' is taking place, with a burgeoning of academic work that takes seriously the place of seas and oceans in understanding socio-cultural and political life, past and present. Yet, there is a significant gap concerning the ways in which we engage with seas and oceans, with a will to enliven action and evoke change. This book explores these challenges, offering insights from spatial planning, architectural design, geography, educational studies, anthropology and cultural studies. An examination through these lenses can help us to better understand human relationships with the seas and oceans, and promote an ethic of care for the future.

Accurate predictions of storm surge are of importance in many coastal areas in the world to avoid and mitigate its destructive impacts. For this purpose the physically-based (process) numerical models are typically utilized. However, in data-rich cases, one may use data-driven methods aiming at reconstructing the internal patterns of the modelled processes and relationships between the observed descriptive variables. This book focuses on data-driven modelling using methods of nonlinear dynamics and chaos theory. First, some fundamentals of physical oceanography, nonlinear dynamics and chaos, computational intelligence and European operational storm surge models are covered. After that a number of improvements in building chaotic models are presented: nonlinear time series analysis, multi-step prediction, phase space dimensionality reduction, techniques dealing with incomplete time series, phase error correction, finding true neighbours, optimization of chaotic model, data assimilation and multi-model ensemble prediction. The major case study is surge prediction in the North Sea, with some tests on a Caribbean Sea case. The modelling results showed that the enhanced predictive chaotic models can serve as an efficient tool for accurate and reliable short and mid-term predictions of storm surges in order to support decision-makers for flood prediction and ship navigation.

Coastal Defences aims to present the broad spectrum of methods that engineers use to protect the coastline and investigates the sort of issues that can arise as a result. The first section of the book examines 'traditional' hard techniques such as sea walls and groynes, whilst the second looks at the more recent trend of using techniques more sympathetic to nature. The 'soft' techniques, such as beach feeding and managed realignment, may work more harmoniously with natural processes, but still produce some environmental impacts. By looking at each of the main methods of coastal protection in detail, the book investigates the rationale for using each method and the consequent management issues, presenting a case for and against each of the techniques.

Winds, Waves, and Warriors examines the oceanographic conditions that U.S. military planners considered, or should have considered, when landing troops and vehicles on the beach at three historic amphibious assaults: Normandy, Tarawa, and Inchon. Oceanographer Thomas M. Mitchell brings welcome insight into a little-studied yet extraordinary aspect of ground warfare by explaining why certain tidal and weather conditions existed at those specific places and times, and how they affected the Army and Marine foot soldiers fighting to get ashore. Mitchell offers easy-to-understand descriptions of basic oceanographic concepts and applies them to actual amphibious operations. Winds and waves hampered the Allies' efforts on D-Day but less than they would have had the soldiers attempted storming the beach at Normandy the day before or after. Coral reefs and tides contributed to high Marine casualties at Tarawa Atoll in the Pacific. General Douglas MacArthur used the element of surprise by attacking the North Koreans at Inchon despite treacherous soft mud bottoms and unfavorable tidal conditions. Mitchell details how wartime necessity led to the development of clever methods to estimate such factors as water depth, beach slope, and underwater shoals, all of which affected troops' assaults and potentially changed the outcomes of key battles. An Army Air Corps lieutenant, for example, dug a hole on the beach at Normandy to help him predict tides more accurately. The Army's Beach Erosion Board and research groups such as the Scripps Institution of Oceanography exploited elementary principles of physical oceanography to develop crude but effective instruments and techniques for ocean remote sensing and forecasting. Indeed, soldiers, Marines, staff planners, commanders, oceanographers, meteorologists, and researchers all contributed to some of the largest and most important military invasions in history. Winds, Waves, and Warriors tells of the U.S. military's struggles with a foe that was sometimes just as formidable and unpredictable as the opposing army. When unheeded, unfavorable weather and ocean conditions could lead to tragic and avoidable deaths. The threat posed by the ocean at these three historic battles was an important factor not only in the outcomes of these operations but also to the survival of the troops who fought there.
