This introductory book on oceans shows children where the five oceans are on a simple map and on photos of planet Earth. Children are asked to find the icy oceans at the top and bottom of Earth and the warm oceans around the middle of Earth, where coral reefs are found. Amazing photos of a huge moray eel, sea turtle, shark, octopus, and whales will delight young readers, as will photos of children playing in ocean waves.
"Books like this one help lead the way to a better climate future for all inhabitants of Mother Earth. We are all in this together!" — Jeff Bridges, Academy Award winner and environmentalist A little more than 70 percent of Planet Earth is ocean. So wouldn’t a better name for our global home be Planet Ocean? You may be surprised at just how closely YOU are connected to the ocean. Regardless of where you live, every breath you take and every drop of water you drink links you to the ocean. And because of this connection, the ocean’s health affects all of us. Dive in with author Patricia Newman and photographer Annie Crawley—visit the Coral Triangle near Indonesia, the Salish Sea in the Pacific Northwest, and the Arctic Ocean at the top of the world. Find out about problems including climate change, ocean acidification, and plastic pollution, and meet inspiring local people who are leading the way to reverse the ways in which humans have harmed the ocean. Planet Ocean shows us how to stop thinking of ourselves as existing separate from the ocean and how to start taking better care of this precious resource.
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.

DK's Ocean is a highly illustrated encyclopedia of the marine environment. It not only covers marine life and physical oceanography, from the geology of the seafloor to the chemistry of seawater, but also includes an atlas of the world's oceans and seas compiled using satellite data. Visual catalogs throughout the book contain profiles of living organisms and key locations. With comprehensively updated text, artwork, and images, the second edition of DK's exhaustive guide to the underwater world is the most definitive visual guide to the world's oceans on the market.
An Ocean in Mind poses a number of provocative questions about the ways in which the human mind acquires, utilizes, and transmits different forms of knowledge. Author Will Kyselka has woven an exploration of this theme around the story of the Hōkūleʻa, a re-creation of a traditional Polynesian sailing vessel that completed a successful roundtrip journey between Hawaii and Tahiti in 1980. From this story emerges portraits of two men who played integral roles in that voyage. Nainoa Thompson, a young man of Hawaiian descent, kept the Hōkūleʻa on its 6,000-mile course using only the stars and the sea as his guides. He was inspired by Carolinian navigator Mau Piailug, a gentle, softspoken man with keen instincts and an unlimited understanding of the oceans and heavens derived from his Oceanic cultural past. Thompson also worked with Kyselka to generate a body of information concerning movement of the stars using the Bishop Museum Planetarium as a resource. How Thompson was eventually able to forge these vastly different approaches to knowledge into a cogent wayfinding system uniquely his own, and his rediscovery of an almost forgotten cultural heritage in the process, makes for a thrilling adventure story.
The 4.4-billion-year history of the oceans and their role in Earth's climate system It has often been said that we know more about the moon than we do about our own oceans. In fact, we know a great deal more about the oceans than many people realize. Scientists know that our actions today are shaping the oceans and climate of tomorrow—and that if we continue to act recklessly, the consequences will be dire. Eelco Rohling traces the 4.4-billion-year history of Earth's oceans while also shedding light on the critical role they play in our planet's climate system. This timely and accessible book explores the close interrelationships of the oceans, climate, solid Earth processes, and life, using the context of Earth and ocean history to provide perspective on humankind's impacts on the health and habitability of our planet.
Despite the fact that the vast majority of the earth’s surface is made up of oceans, there has been surprisingly little work by geographers which critically examines the ocean-space and our knowledge and perceptions of it. This book employs a broad conceptual and methodological framework to analyse specific events that have contributed to the production of geographical knowledge about the ocean. These include, but are not limited to, Christopher Columbus’ first transatlantic journey, the mapping of nonexistent islands, the establishment of transoceanic trade routes, the discovery of largescale water movements, the HMS Challenger expedition, the search for the elusive Terra Australis Incognita, the formulation of the theory of continental drift and the mapping of the seabed. Using a combination of original, empirical (archival, material and cartographic), and theoretical sources, this book uniquely brings together fascinating narratives throughout history to produce a representation and mapping of geographical oceanic knowledge. It questions how we know what we know about the oceans and how this knowledge is represented and mapped. The book then uses this representation and mapping as a way to coherently trace the evolution of oceanic spatial awareness. In recent years, particularly in historical geography, discovering and knowing the ocean-space has been a completely separate enterprise from discovering and colonising the lands beyond it. There has been such focus on studying colonised lands, yet the oceans between them have been neglected. This book gives the geographical ocean a voice to be acknowledged as a space where history, geography and indeed historical geography took place.
A collection of Brian Skerry's ocean photography, including sharks in the Bahamas, leatherback sea turtles in Trinidad, and right whales in the Auckland Islands.
Recent decades have been marked by the decline or collapse of one fishery after another around the world, from swordfish in the North Atlantic to orange roughy in the South Pacific. While the effects of a collapse on local economies and fishing-dependent communities have generated much discussion, little attention has been paid to its impacts on the overall health of the ocean's ecosystems. In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean presents the first empirical assessment of the status of ecosystems in the North Atlantic ocean. Drawing on a wide range of studies including original research conducted for this volume, the authors analyze 14 large marine ecosystems to provide an indisputable picture of an ocean whose ecology has been dramatically altered, resulting in a phenomenon described by the authors as "fishing down the food web." The book: provides a snapshot of the past health of the North Atlantic and compares it to its present status presents a rigorous scientific assessment based on the key criteria of fisheries catches, biomass, and trophic level considers the factors that have led to the current situation describes the policy options available for halting the decline offers recommendations for restoring the North Atlantic An original and powerful series of maps and charts illustrate where the effects of overfishing are the most pronounced and highlight the interactions among various factors contributing to the overall decline of the North Atlantic's ecosystems. This is the first in a series of assessments by the world's leading marine scientists, entitled "The State of the World's Oceans." In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean is a landmark study, the first of its kind to make a comprehensive, ecosystem-based assessment of the North Atlantic Ocean, and will be essential reading for policymakers at the state, national, and international level concerned with fisheries management, as well for scientists, researchers, and activists concerned with marine issues or fishing and the fisheries industry.
In this book, geologists Jan Zalasiewicz and Mark Williams consider the deep history of oceans, how and when they may have formed on the young Earth - topics of intense current research - how they became salty, and how they evolved through Earth history.
