Inside the epic quest to find life on the water-rich moons at the outer reaches of the solar system Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have existed for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out. Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds. Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.
A collection of questions and answers about the oceans including "What is sand made of?" and "Which sea animals sing like canaries?".
This book shows where five oceans are located, where paper comes from, how hikes can be fun, and why we need clocks and watches.
Includes reading group guide and excerpt from the author's novel, Dry as rain.
There is a growing concern over the ubiquitous distribution of plastic pollution that is evolving in the Beaufort Gyre in the Arctic Ocean, prompting international collaboration and new environmental measures. Marine pollution is recognised as an immediate threat to both land and marine ecosystems. Satellites have proven useful in identifying ocean plastic patches and current movements in other oceans but little research has been applied to the Arctic, a region that impacts eight countries making up the Arctic Circle. This interdisciplinary team project investigates the use of Sentinel-2, Sentinel-6, Fourier-Transform Spectroscopy, stratospheric balloons and autonomous underwater vehicles to provide an integrated strategy, including communication and outreach, to tackling marine plastic pollution while recognizing that it is necessary to also prevent plastics from entering the ocean in the first place.

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.
This single-volume resource explores the five major oceans of the world, addressing current issues such as sea rise and climate change and explaining the significance of the oceans from historical, geographic, and cultural perspectives. The World's Oceans: Geography, History, and Environment is a one-stop resource that describes in-depth the Arctic, Atlantic, Indian, Pacific, and Southern Oceans and identifies their importance, today and throughout history. Essays address the subject areas of oceans and seas in world culture, fishing and shipping industries through history, ocean exploration, and climate change and oceans. The book also presents dozens of entries covering a breadth of topics on human culture, the environment, history, and current issues as they relate to the oceans and ocean life. Sample entries provide detailed information on topics such as the Bermuda Triangle, Coral Reefs, the Great Pacific Garbage Patch, Ice Melt, Myths and Legends, Piracy, and Whaling. Contributions to the work come from top researchers in the fields of history and maritime studies, including Paul D'Arcy, John Gillis, Tom Hoogervorst, Michael North, and Lincoln Paine. The volume highlights the numerous ways in which Earth's oceans have influenced culture and society, from the earliest seafaring civilizations to the future of the planet.
Readers learn the value of knowing how to read maps in this resourceful text about a fascinating subject. Maps of oceans reveal important details about a part of the planet humans still know so little about. As readers learn about the creation and interpretation of maps of the ocean, they're introduced to essential science curriculum topics in a fun way. In addition to the accessible and age-appropriate main text, useful diagrams and graphic organizers, informational fact boxes, a detailed glossary, and stunning visual examples of maps spark readers' interest in looking more closely at the world's oceans.
From both a historical and scientific point of view, above and below the surface, this engaging guide brings the world’s oceans to life through fun facts, illustrations, and in-depth information. Interactive activities appear throughout, ranging from making solar stills and simple fishing spears to experimenting with a homemade diving bell and figuring out how much water it really takes to survive. With the oceans being the least explored environment on Earth, this reference illuminates some of the most incredible and surprising plants and animals as well as how to survive and navigate these vast expanses.
