Book Description
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.

Book Description
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.

Book Description
From a brilliant Brookings Institution expert, an “important” (The Wall Street Journal) and “penetrating historical and political study” (Nature) of the critical role that oceans play in the daily struggle for global power, in the bestselling tradition of Robert Kaplan’s The Revenge of Geography. For centuries, oceans were the chessboard on which empires battled for supremacy. But in the nuclear age, air power and missile systems dominated our worries about security, and for the United States, the economy was largely driven by domestic production, with trucking and railways that crisscrossed the continent serving as the primary modes of commercial transit. All that has changed, as nine-tenths of global commerce and the bulk of energy trade is today linked to sea-based flows. A brightly painted forty-foot steel shipping container loaded in Asia with twenty tons of goods may arrive literally anywhere else in the world; how that really happens and who actually profits from it show that the struggle for power on the seas is a critical issue today. Now, in vivid, closely observed prose, Bruce Jones conducts us on a fascinating voyage through the great modern ports and naval bases—from the vast container ports of Hong Kong and Shanghai to the vital naval base of the American Seventh Fleet in Hawaii to the sophisticated security arrangements in the Port of New York. Along the way, the book illustrates how global commerce works, that we are amidst a global naval arms race, and why the oceans are so crucial to America’s standing going forward. As Jones reveals, the three great geopolitical struggles of our time—for military power, for economic dominance, and over our changing climate—are playing out atop, within, and below the world’s oceans. The essential question, he shows, is this: who will rule the waves and set the terms of the world to come?

Book Description
The World Ocean Assessment - or, to give its full title, The First Global Integrated Marine Assessment - is the outcome of the first cycle of the United Nations' Regular Process for Global Reporting and Assessment of the State of the Marine Environment, including Socioeconomic Aspects. The Assessment provides vital, scientifically-grounded bases for the consideration of ocean issues, including climate change, by governments, intergovernmental agencies, non-governmental agencies and all other stakeholders and policymakers involved in ocean affairs. Together with future assessments and related initiatives, it will support the implementation of the recently adopted 2030 Agenda for Sustainable Development, particularly its ocean-related goals. Moreover, it will also form an important reference text for marine science courses.

Book Description
World Oceans: A Reference Handbook offers an in-depth discussion of the world's oceans. It discusses the marine life that is dependent on the sea as well as the problems threatening the health of the ocean and its wildlife. World Oceans: A Reference Handbook opens with an overview of the history of human knowledge and understanding of the oceans and cryosphere, along with related scientific, technological, social, political, and other factors. The second chapter presents and discusses about a dozen major problems facing the Earth's oceans today, along with possible solutions. The third chapter provides interested individuals with an opportunity to express their thoughts and ideas on today's ocean issues, and remaining chapters provide additional resources, such as a bibliography, a chronology, and a glossary, to assist the reader in her or his further study of the issue. Where most books for young adults learning about world oceans take a purely expository treatment, this book provides readers with additional information as well as resources, allowing them to learn more and inform further study of the subject.

Book Description
Shifting Baselines explores the real-world implications of a groundbreaking idea: we must understand the oceans of the past to protect the oceans of the future. In 1995, acclaimed marine biologist Daniel Pauly coined the term "shifting baselines" to describe a phenomenon of lowered expectations, in which each generation regards a progressively poorer natural world as normal. This seminal volume expands on Pauly's work, showing how skewed visions of the past have led to disastrous marine policies and why historical perspective is critical to revitalize fisheries and ecosystems. Edited by marine ecologists Jeremy Jackson and Enric Sala, and historian Karen Alexander, the book brings together knowledge from disparate disciplines to paint a more realistic picture of past fisheries. The authors use case studies on the cod fishery and the connection between sardine and anchovy populations, among others, to explain various methods for studying historic trends and the intricate relationships between species. Subsequent chapters offer recommendations about both specific research methods and effective management. This practical information is framed by inspiring essays by Carl Safina and Randy Olson on a personal experience of shifting baselines and the importance of human stories in describing this phenomenon to a broad public. While each contributor brings a different expertise to bear, all agree on the importance of historical perspective for effective fisheries management. Readers, from students to professionals, will benefit enormously from this informed hindsight.
