From one of the most admired admirals of his generation—and the only admiral to serve as Supreme Allied Commander at NATO—comes a remarkable voyage through all of the world’s most important bodies of water, providing the story of naval power as a driver of human history and a crucial element in our current geopolitical path. From the time of the Greeks and the Persians clashing in the Mediterranean, sea power has determined world power. To an extent that is often underappreciated, it still does. No one understands this better than Admiral Jim Stavridis. In Sea Power, Admiral Stavridis takes us with him on a tour of the world’s oceans from the admiral’s chair, showing us how the geography of the oceans has shaped the destiny of nations, and how naval power has in a real sense made the world we live in today, and will shape the world we live in tomorrow. Not least, Sea Power is marvelous naval history, giving us fresh insight into great naval engagements from the battles of Salamis and Lepanto through to Trafalgar, the Battle of the Atlantic, and submarine conflicts of the Cold War. It is also a keen-eyed reckoning with the likely sites of our next major naval conflicts, particularly the Arctic Ocean, Eastern Mediterranean, and the South China Sea. Finally, Sea Power steps back to take a holistic view of the plagues to our oceans that are best seen that way, from piracy to pollution. When most of us look at a globe, we focus on the shape of the of the seven continents. Admiral Stavridis sees the shapes of the seven seas. After reading Sea Power, you will too. Not since Alfred Thayer Mahan’s legendary The Influence of Sea Power upon History have we had such a powerful reckoning with this vital subject.

The world’s oceans cover 70% of the earth’s surface and are home to a myriad of amazing and beautiful creatures. However, the biodiversity of the oceans is incre- ingly coming under serious threat from many human activities including overfi- ing, use of destructive fishing methods, pollution and commercial aquaculture. In addition, climate change is already having an impact on some marine ecosystems. This book discusses some of the major threats facing marine ecosystems by cons- ering a range of topics, under chapters discussing biodiversity (Chapter 1), fisheries (Chapter 2), aquaculture (Chapter 3), pollution (Chapter 4) and the impacts of increasing greenhouse gas emissions (Chapter 5). It goes on to explore solutions to the problems by discussing equitable and sustainable management of the oceans (Chapter 6) and protecting marine ecosystems using marine reserves (Chapter 7). Presently, 76% of the oceans are fully or over-exploited with respect to fishing, and many species have been severely depleted. It is abundantly clear that, in general, current fisheries management regimes are to blame for much of the widespread degradation of the oceans. Many policy-makers and scientists now agree that we must adopt a radical new approach to managing the seas – one that is precautionary in nature and has protection of the whole marine ecosystem as its primary objective. This ‘ecosystem-based approach’ is vital if we are to ensure the health of our oceans for future generations.

The world's oceans account for roughly 71 percent of the planet's surface and 99 percent of its livable volume. Any study of this huge habitat requires a solid foundation in the principles that underlie marine biology and physical and chemical oceanography, yet until now undergraduate textbooks have largely presented compilations of facts rather than explanations of principles. How the Ocean Works fills this gap, providing a concise and accessible college-level introduction to marine science that is also ideal for general readers. How are winds and currents driven? What is the dilemma of the two-layered ocean? Mark Denny explains key concepts like these in rich and fascinating detail. He explores early scientific knowledge of oceans, photosynthesis, trophic interactions and energy flow, and the impacts of human activities on marine and atmospheric systems. Focusing each chapter on a major topic and carefully explaining the principles and theory involved, Denny gives readers the conceptual building blocks needed to develop a coherent picture of the living ocean. How the Ocean Works is an indispensable resource that teaches readers how to think about the ocean--its biology, mechanics, and conservation. Provides a concise, up-to-date introduction to marine science Develops the conceptual basis needed to understand how the ocean works Explains fundamental principles and theory Includes color illustrations and informative diagrams Serves as a college textbook and a reference for general readers Some images inside the book are unavailable due to digital copyright restrictions.

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.

A Silent Spring for oceans, written by "the Rachel Carson of the fish world" (The New York Times) Who can forget the sense of wonder with which they discovered the creatures of the deep? In this vibrant hymn to the sea, Callum Roberts—one of the world’s foremost conservation biologists—leads readers on a fascinating tour of mankind’s relationship to the sea, from the earliest traces of water on earth to the oceans as we know them today. In the process, Roberts looks at how the taming of the oceans has shaped human civilization and affected marine life. We have always been fish eaters, from the dawn of civilization, but in the last twenty years we have transformed the oceans beyond recognition. Putting our exploitation of the seas into historical context, Roberts offers a devastating account of the impact of modern fishing techniques, pollution, and climate change, and reveals what it would take to steer the right course while there is still time. Like Four Fish and The Omnivore’s Dilemma, The Ocean of Life takes a long view to tell a story in which each one of us has a role to play.

Our world is a water world. Seventy percent of our planet consists of ocean. However, geography has traditionally overlooked this vital component of the earth's composition. The word 'geography' directly translates as 'earth writing' and in line with this definition the discipline has preoccupied itself with the study of terrestrial spaces of society and nature. This book challenges human geography's preoccupation with the terrestrial, investigating the terra incognita of the seas and oceans. Linking to new theoretical debates shaping the geographic discipline (such as affect, assemblage, emotion, hybridity and the more-than-human), this volume unlocks new knowledge concerning the human geographies of ocean space. The book casts adrift stable, bounded and fixed conceptions of space and advances geographical understanding based on the world as 'becoming', changing, mobile and processional. This ontology supports the notion that the oceans are not simply fluid in a literal way, but also in a conceptual sense, suggesting that the seas have their own fluid natures - their own capacities and agencies - which are co-fabricated with social and cultural life. This book features twelve chapters, authored by key academics contributing to this growing field of research. The book is divided into three sections, including an Introduction by the editors and a foreword by Prof. Philip E. Steinberg, the leading scholar in the field of maritime geographies. The first section of the book considers the ways in which different watery spaces from the Atlantic Ocean to the Mediterranean Sea have been conceptualized, theorized and ‘known’ through metaphors, voyages of discovery and scientific endeavour. The second section examines how oceans are experienced; through various activities including driving on water, kayaking in water and diving under water. The final section explores the relations between human life and the nature of the sea as a material, mobile and more-than-human space, examining the influences of the ocean on the migratory practices of fishermen in Senegal, to the more-than-human geographies of the contemporary scallop industry, the historical journeys of steam ship companies and the pirate radio enterprise. Oceans are fundamental to the workings of the world as we know it. Critical human activities take place at sea, including trade, tourism, migration, scientific exploration and resource exploitation. The water world is therefore significantly entwined with our everyday lives. This book offers a novel and important contribution to an ever-emerging cross-disciplinary subject matter.
