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 brand new edition of A Drop in the Ocean from the Science Works series, featuring lively storytelling and fun, engaging illustrations to aid children in their learning. Our world is full of water. We swim in it. We Swallow it. We are even made of it (mostly). In this revised edition from Jacqui Bailey, we follow the passage of a water droplet, from the time when it evaporates from the ocean and becomes the water vapour that makes up clouds to the moment it falls as rain. We learn how water is cleaned and used before being returned once again to this never-ending cycle. This book also contains an experiment, more great facts to know, useful websites and an index. Book band: Lime Ideal for KS2.

A scientist’s exploration of the "ocean engine"—the physics behind the ocean’s systems—and why it matters. All of Earth’s oceans, from the equator to the poles, are a single engine powered by sunlight, driving huge flows of energy, water, life, and raw materials. In The Blue Machine, physicist and oceanographer Helen Czerski illustrates the mechanisms behind this defining feature of our planet, voyaging from the depths of the ocean floor to tropical coral reefs, estuaries that feed into shallow coastal seas, and Arctic ice floes. Through stories of history, culture, and animals, she explains how water temperature, salinity, gravity, and the movement of Earth’s tectonic plates all interact in a complex dance, supporting life at the smallest scale—plankton—and the largest—giant sea turtles, whales, humankind. From the ancient Polynesians who navigated the Pacific by reading the waves, to permanent residents of the deep such as the Greenland shark that can live for hundreds of years, she introduces the messengers, passengers, and voyagers that rely on interlinked systems of vast currents, invisible ocean walls, and underwater waterfalls. Most important, however, Czerski reveals that while the ocean engine has sustained us for thousands of years, today it is faced with urgent threats. By understanding how the ocean works, and its essential role in our global system, we can learn how to protect our blue machine. Timely, elegant, and passionately argued, The Blue Machine presents a fresh perspective on what it means to be a citizen of an ocean planet.

We Are the Ocean is a collection of essays, fiction, and poetry by Epeli Hau‘ofa, whose writing over the past three decades has consistently challenged prevailing notions about Oceania and prescriptions for its development. He highlights major problems confronted by the region and suggests alternative perspectives and ways in which its people might reorganize to relate effectively to the changing world. Hau‘ofa’s essays criss-cross Oceania, creating a navigator’s star chart of discussion and debate. Spurning the arcana of the intellectual establishments where he was schooled, Hau‘ofa has crafted a distinctive—often lyrical, at times angry—voice that speaks directly to the people of the region and the general reader. He conveys his thoughts from diverse standpoints: university-based analyst, essayist, satirist and humorist, and practical catalyst for creativity. According to Hau‘ofa, only through creative originality in all fields of endeavor can the people of Oceania hope to strengthen their capacity to engage the forces of globalization. “Our Sea of Islands,” “The Ocean in Us,” “Pasts to Remember,” and “Our Place Within,” all of which are included in this collection, outline some of Hau‘ofa’s ideas for the emergence of a stronger and freer Oceania. Throughout he expresses his concern with the environment and suggests that the most important role that the “people of the sea” can assume is as custodians of the Pacific, the vast area of the world’s largest body of water.

Object Lessons is a series of short, beautifully designed books about the hidden lives of ordinary things. The ocean comprises the largest object on our planet. Retelling human history from an oceanic rather than terrestrial point of view unsettles our relationship with the natural environment. Our engagement with the world's oceans can be destructive, as with today's deluge of plastic trash and acidification, but the mismatch between small bodies and vast seas also emphasizes the frailty and resilience of human experience. From ancient stories of shipwrecked sailors to the containerized future of 21st-century commerce, Ocean splashes the histories we thought we knew into salty and unfamiliar places. Object Lessons is published in partnership with an essay series in The Atlantic.

“The Southern Ocean is a wild and elusive place, an ocean like no other. With its waters lying between the Antarctic continent and the southern coastlines of Australia, New Zealand, South America, and South Africa, it is the most remote and inaccessible part of the planetary ocean, the only part that flows around Earth unimpeded by any landmass. It is notorious amongst sailors for its tempestuous winds and hazardous fog and ice. Yet it is a difficult ocean to pin down. Its southern boundary, defined by the icy continent of Antarctica, is constantly moving in a seasonal dance of freeze and thaw. To the north, its waters meet and mingle with those of the Atlantic, Indian, and Pacific Oceans along a fluid boundary that defies the neat lines of a cartographer.” So begins Joy McCann’s Wild Sea, the remarkable story of the world’s remote Southern, or Antarctic, Ocean. Unlike the Pacific, Atlantic, Indian, and Arctic Oceans with their long maritime histories, little is known about the Southern Ocean. This book takes readers beyond the familiar heroic narratives of polar exploration to explore the nature of this stormy circumpolar ocean and its place in Western and Indigenous histories. Drawing from a vast archive of charts and maps, sea captains’ journals, whalers’ log books, missionaries’ correspondence, voyagers’ letters, scientific reports, stories, myths, and her own experiences, McCann embarks on a voyage of discovery across its surfaces and into its depths, revealing its distinctive physical and biological processes as well as the people, species, events, and ideas that have shaped our perceptions of it. The result is both a global story of changing scientific knowledge about oceans and their vulnerability to human actions and a local one, showing how the Southern Ocean has defined and sustained southern environments and people over time. Beautifully and powerfully written, Wild Sea will raise a broader awareness and appreciation of the natural and cultural history of this little-known ocean and its emerging importance as a barometer of planetary climate change.

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.
