"The main character of the book, 'Dhyum' is based on a real dugong that was satellite-tagged in 2010 at Mabuiag Island in Torres Strait. Dhyum was named by students from the local Tagai State College."--Cover verso.
Remote sensing stands as the defining technology in our ability to monitor coral reefs, as well as their biophysical properties and associated processes, at regional to global scales. With overwhelming evidence that much of Earth’s reefs are in decline, our need for large-scale, repeatable assessments of reefs has never been so great. Fortunately, the last two decades have seen a rapid expansion in the ability for remote sensing to map and monitor the coral reef ecosystem, its overlying water column, and surrounding environment. Remote sensing is now a fundamental tool for the mapping, monitoring and management of coral reef ecosystems. Remote sensing offers repeatable, quantitative assessments of habitat and environmental characteristics over spatially extensive areas. As the multi-disciplinary field of coral reef remote sensing continues to mature, results demonstrate that the techniques and capabilities continue to improve. New developments allow reef assessments and mapping to be performed with higher accuracy, across greater spatial areas, and with greater temporal frequency. The increased level of information that remote sensing now makes available also allows more complex scientific questions to be addressed. As defined for this book, remote sensing includes the vast array of geospatial data collected from land, water, ship, airborne and satellite platforms. The book is organized by technology, including: visible and infrared sensing using photographic, multispectral and hyperspectral instruments; active sensing using light detection and ranging (LiDAR); acoustic sensing using ship, autonomous underwater vehicle (AUV) and in-water platforms; and thermal and radar instruments. Emphasis and Audience This book serves multiple roles. It offers an overview of the current state-of-the-art technologies for reef mapping, provides detailed technical information for coral reef remote sensing specialists, imparts insight on the scientific questions that can be tackled using this technology, and also includes a foundation for those new to reef remote sensing. The individual sections of the book include introductory overviews of four main types of remotely sensed data used to study coral reefs, followed by specific examples demonstrating practical applications of the different technologies being discussed. Guidelines for selecting the most appropriate sensor for particular applications are provided, including an overview of how to utilize remote sensing data as an effective tool in science and management. The text is richly illustrated with examples of each sensing technology applied to a range of scientific, monitoring and management questions in reefs around the world. As such, the book is broadly accessible to a general audience, as well as students, managers, remote sensing specialists and anyone else working with coral reef ecosystems.
This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!

Looks at some of the endangered animals that call North America home, including kangaroo rats, polar bears, condors, sturgeons, and red wolves.
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.
This spectacular book introduces children to some of the most endangered species on Earth, from the pygymy sloth to Attenborough's pitcher plant. It explores what scientists are doing to save species and what we can do to help, featuring wildlife that is critically endangered alongside species that have been brought back from the brink of extinction.
Explore the wonders and beauties of the ocean's kelp forests in this latest addition to the acclaimed Over and Under series. Award-winning duo Kate Messner and Christopher Silas Neal return in this latest addition to the Over and Under picture book series, this time exploring the rich, interconnected ecosystem of the ocean! Over the waves, the sea lions bark and seagulls wheel and call. The bay is smooth and bright in the sun. But under the waves, there's a whole hidden forest, full of whales and wolf eels, sardines and sea bass, leopard sharks and luminous jellies, as well as the waving kelp that shelters them all. Discover the magical depths of the kelp forest, and all the fascinating creatures living just a paddle's length away—over and under the waves. SO MANY FASCINATING FACTS: Kids are endlessly curious about the natural world and the wildly varied animals and plants living in it—and the ocean is FULL of amazing and surprising life! ENVIRONMENTAL AWARENESS MADE WONDERFUL: Preservation of our wilderness—and of our oceans in particular—is essential, and this book makes such a great, upbeat jumping-off point for discussions of the importance and wonder of our world's natural habitats and ecosystems. THE GORGEOUS UNDERWATER WORLD: This new book in the Over and Under series illuminates the magic and amazing biodiversity of the kelp forest by telling the story of one family's kayaking trip through a real-world ocean ecosystem. Lyrical prose and color-drenched illustrations will draw even the most reluctant readers into the world.
