Our oceans are in an ecological crisis due to their contamination with millions of tons of toxic microplastic particles. In just a few years, the volume of microplastic particles will exceed that of plankton in our oceans and turn them into a huge sea of plastic. This publication brings together numerous international art projects related to environmental activities, DIY biotechnology, and science, and draws attention to the irreversible destruction of our marine ecosystems - the current threat posed by the loss of marine animal biodiversity, for example, or the decline in oxygen production due to massive plankton loss. It also presents current scientific findings on sustainable alternatives to plastic.
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.
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.
This open access book provides a cross-sectoral, multi-scale assessment of marine litter in Africa with a focus on plastics. From distribution, to impacts on environmental and human health, this book looks at what is known scientifically. It includes a policy analysis of the instruments that currently exist, and what is needed to help Africa tackle marine litter-including local and transboundary sources. Across 5 chapters, experts from Africa and beyond have put together a summary of the scientific knowledge currently known about marine litter in Africa. The context of the African continent and future projections form a backdrop on which the scientific knowledge is built. This scientific knowledge incorporates quantities, distributions, and pathways of litter into the marine environment, highlighting where the impacts of marine litter are most felt in Africa. These impacts have widespread effects, with ecological, social, economic, and human health repercussions. While containing detailed scientific information, this book provides a sound knowledge base for policymakers, NGOs and the broader public.
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.

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.
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.

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.

Marine environmental conditions such as storms, storm surges and wave heights are directly experienced by, for example, off-shore operations or coastal populations. The authors review and bring together the state-of-the-art and present day knowledge about historical changes, recent trends and concepts on how marine environmental conditions may change in the future as well as discuss models and data problems.
Marine extremes, as they are conceived of in this volume, encompass environments, activities, events and impacts. Extreme environments found in and around our oceans, including the deep sea and seabed as well as the frozen polar regions, are being seriously affected by both extreme behaviours (dumping and discharge of waste, illegal fishing and piracy) and extreme events (storms, tsunamis, extreme waves and marine heatwaves). The aim of this book is to highlight the multi-disciplinary knowledge and inputs needed to address marine extremes and thereafter to explore opportunities and current challenges. Safe and healthy oceans are important for economic, recreational and cultural activities, in addition to the maintenance of ecosystem services upon which we rely. This volume gathers a unique mix of researchers working on scientific aspects of biological ecosystems and physical processes together with social scientists exploring law and governance options, community preferences, cultural values, economic aspects and criminological drivers and approaches. The multi-disciplinary feature of this book breaks down barriers that arise between disparate fields of research so that integrated solutions to ocean challenges can be found. Overall, this book argues that if we are to achieve sustainable utilisation of our oceans and blue economy goals we must better understand, and respond to, the extreme environments, activities, events and impacts. The book is a valuable addition to the literature and will be of interest to researchers in marine science, ocean governance and natural resource economics, as well as to professionals and government officials concerned with marine policy and planning.

The Great Barrier Reef is located along the coast of Queensland in north-east Australia and is the world's largest coral reef ecosystem. Designated a World Heritage Area, it has been subject to increasing pressures from tourism, fishing, pollution and climate change, and is now protected as a marine park. This book provides an original account of the environmental history of the Great Barrier Reef, based on extensive archival and oral history research. It documents and explains the main human impacts on the Great Barrier Reef since European settlement in the region, focusing particularly on the century from 1860 to 1960 which has not previously been fully documented, yet which was a period of unprecedented exploitation of the ecosystem and its resources. The book describes the main changes in coral reefs, islands and marine wildlife that resulted from those impacts. In more recent decades, human impacts on the Great Barrier Reef have spread, accelerated and intensified, with implications for current management and conservation practices. There is now better scientific understanding of the threats faced by the ecosystem. Yet these modern challenges occur against a background of historical levels of exploitation that is little-known, and that has reduced the ecosystem's resilience. The author provides a compelling narrative of how one of the world's most iconic and vulnerable ecosystems has been exploited and degraded, but also how some early conservation practices emerged.
This volume contains the ten most cited articles that have appeared in the journal Atmosphere-Ocean since 1995. These articles cover a wide range of topics in meteorology, climatology and oceanography. Modelling work is represented in five papers, covering global climate model development; a cumulus parameterization scheme for global climate models; development of a regional forecast modelling system and parameterization of peatland hydraulic processes for climate models. Data rehabilitation and compilation in order to support trend analysis work on comprehensive precipitation and temperature data sets is presented in four papers. Field studies are represented by a paper on the circumpolar lead system. While the modelling studies are global in their application and applicability, the data analysis and field study papers cover environments that are specifically, but not uniquely, Canadian. This book will be of interest to researchers, students and professionals in the various sub-fields of meteorology, oceanography and climate science.
The ocean is opaque to electromagnetic radiation and transparent to low frequency sound, so acoustical methodologies are an important tool for sensing the undersea world. Stochastic sound-speed fluctuations in the ocean, such as those caused by internal waves, result in a progressive randomisation of acoustic signals as they traverse the ocean environment. This signal randomisation imposes a limit to the effectiveness of ocean acoustic remote sensing, navigation and communication. Sound Propagation through the Stochastic Ocean provides a comprehensive treatment of developments in the field of statistical ocean acoustics over the last 35 years. This will be of fundamental interest to oceanographers, marine biologists, geophysicists, engineers, applied mathematicians, and physicists. Key discoveries in topics such as internal waves, ray chaos, Feynman path integrals, and mode transport theory are addressed with illustrations from ocean observations. The topics are presented at an approachable level for advanced students and seasoned researchers alike.
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. |
