Plus: An encyclopedia of marine life, with a list of threatened species. 208 pages (all in color), 8 7/8 x 12.

Just as humans scale the highest mountains, they also explore the deepest depths of the world's oceans. In this lavish atlas, a variety of maps depict the fascinating geographical landmarks of the ocean floor: volcanoes that rise suddenly from the deep ocean; seamounts and ridges that contain rich mineral deposits; shipwrecks (the Titanic is only one example among many); and marine life in the hidden depths of the ocean that until now has been invisible to humans. Deep-sea exploration is one of the great achievements of the twentieth century. Expeditions to the bottom of the sea, for example Picard's groundbreaking explorations in a submersible, made sensational news. Still, these excursions to the deepest places on earth were isolated events. It wasn't until after the Second World War that a comprehensive picture of the ocean floor began to emerge. World Atlas of the Oceans brings these images together in a new and truly unique look at the oceans. The General Bathymetric Chart of the Oceans (or GEBCO), contained in this atlas, has never been published. And, relief maps and satellite images of the oceans provide detailed pictures of the hidden recesses of the world's oceans. World Atlas of the Oceans is the only cartographic work of its kind to document the ocean floor with its mountains, volcanoes, fracture zones, and outline of tectonic plates in such amazing detail.

Detailing a mysterious realm that's as vital to our existence as the air we breathe, this new atlas immerses readers in the wonders of the deep through more than 250 up-to-the-minute maps, photographs, and satellite images.

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.

The Biology of Sharks and Rays is a comprehensive resource on the biological and physiological characteristics of the cartilaginous fishes: sharks, rays, and chimaeras. In sixteen chapters, organized by theme, A. Peter Klimley covers a broad spectrum of topics, including taxonomy, morphology, ecology, and physiology. For example, he explains the body design of sharks and why the ridged, toothlike denticles that cover their entire bodies are present on only part of the rays' bodies and are absent from those of chimaeras. Another chapter explores the anatomy of the jaws and the role of the muscles and teeth in jaw extension, seizure, and handling of prey. The chapters are richly illustrated with pictures of sharks, diagrams of sensory organs, drawings of the body postures of sharks during threat and reproductive displays, and maps showing the extent of the species' foraging range and long-distance migrations. Each chapter commences with an anecdote from the author about his own personal experience with the topic, followed by thought-provoking questions and a list of recommended readings in the scientific literature.  The book will be a useful textbook for advanced ichthyology students as well as an encyclopedic source for those seeking a greater understanding of these fascinating creatures.

No detailed description available for "Field Guide to Sharks, Rays and Chimaeras of the East Coast of North America".

Sharks are the top predators in many marine ecosystems. But tales of the killer instincts and fearsomely sharp senses of these hunters can obscure their full life histories. In fact, sharks are characterful, exhibit surprisingly complex behaviors, and lead secretive lives full of interest in every type of marine habitat. The Lives of Sharks is a fascinating and beautifully illustrated guide to these iconic marine creatures from two world-renowned experts. This book explores shark physiology, anatomy, behavior, ecology, and evolution, as well as conservation and the impact of human activity on shark populations. With stunning photographs and illustrations, as well as profiles of selected species, this is a comprehensive, authoritative, and inviting introduction to global shark life today.

Deliberately breaking with the classical biology-centered description of marine organisms and their products, this reference emphasizes microbial technology over basic biology, setting it apart from its predecessors. As such, it systematically covers the technology behind high-value compounds for use as pharmaceuticals, nutraceuticals or cosmetics, from prospecting to production issues. Following a definition of the field, the book goes on to address all industrially important aspects of marine microbial biotechnology. The first main part contains a description of the major production organisms, from archaebacteria to cyanobacteria to algae and symbionts, including their genetic engineering. The remaining four parts look at commercially important compounds produced by these microorganisms together with their applications. Throughout, the emphasis is on technological considerations, and the future potential of these organisms or compound classes is discussed. A valuable and forward-looking resource for innovative biotechnologists in industry as well as in academia.

This book documents the effects of natural hazards on coastal ecosystems in detail. The sea is an indispensable component of the Earth system, and human societies obtain many goods and services from the marine environment. Global warming threatens marine ecosystems through seawater temperature rise, acidification, sea-level rise and the increased frequency of severe storms. The repeated effects of tsunamis also have major impacts on coastal ecosystems. Increases in population and industry activities along the coast cause the degradation of coastal ecosystems through direct and indirect uses of the environment such as reclamation, overexploitation of bioresources, and pollution. Given these facts, we need to improve our understanding of the physical, chemical and biological mechanisms characterizing marine ecosystems, in order to better measure the effects of anthropogenic and natural impacts on the sea and its ecosystems. Equipped with a comprehensive understanding of the sea, including the effects of the main pressures on it, we will have a better idea of the future state of the sea based on several scenarios of global warming. The 16th France-Japan Symposium on Marine Science focused on using advances in oceanography to better understand the current status of the sea from physical, chemical, biological and ecological perspectives, including fishery sciences and integrated approaches.

Marine Community Ecology and Conservation was written to give advanced undergraduate and graduate students a current overview of what is known about the structure, organization, and conservation of organism assemblages that live on the sea floor. It largely focuses on advancements over the past decade since the publication of Marine Community Ecology (2001). Each chapter is written by leading researchers to give students an up-to-date look at these communities, and what remains to be learned about them. The book is organized into three parts. The first part explores general processes that generate pattern in benthic communities. These introductory chapters examine how physical and biological forces interacting with historical and genetic constraints operate to structure marine communities. The second part examines the ecology of specific marine benthic community types, ranging from rocky shores and soft substrate habitats to kelp forests to coral reefs. These chapters are intended to be the most current summaries available of our understanding of these communities. The final part examines conservation and management issues of marine communities. The closing chapters emphasize how pervasively and profoundly marine communities are impacted by humans and outlines how we can use our understanding of these systems to manage and preserve the valuable services and resources they provide. Marine Community Ecology and Conservation is extensively referenced and includes a bibliography of over 5,000 citations. It is suitable as a text for advanced marine ecology courses and seminars, as well as a general reference for students and researchers.

"Emperors of the Deep is a must-read for anyone in love with our oceans and concerned with averting the looming ecological destruction of our planet. McKeever brings to light the importance of sharks and their role as ancient guardians of the seas."--John Hocevar, Oceans Campaign Director, Greenpeace USA When Steven Spielberg released Jaws in the summer of 1975, his adaptation of Peter Benchley's novel forever type-cast sharks as bloodthirsty man-eaters. But, as we all worried whether it was safe to go back into the water, we failed to notice that while sharks account fewer than four human fatalities per year, humans needlessly kill 100 million sharks per year, which has made the species vulnerable for the first time in its existence and put the future of the world's oceans at risk. At once a deep-dive into the misunderstood world of sharks--specifically, great whites, makos, hammerheads, and tigers--and an urgent call to protect them, Emperors of the Deep tells the true story about the ocean's most mysterious, most misunderstood, and most important guardians. From the family-friendly waters of Cape Cod to the coral reefs of the Central Pacific, where great whites mysteriously congregate every fall in what scientists refer to as Burning Man for white sharks, Safeguard the Seas founder William McKeever introduces us to scientists, conservationists, and world-renowned shark experts who have started unlocking the species' most closely guarded secrets. He also profiles activists around the world fighting to protect sharks and infiltrates a mako-only shark tournament in Montauk to figure out why fishermen continue to hunt them despite their declining numbers. And, to get a close-up view of these underwater emperors and empresses, he enters freely into their world, encountering the 420-million-yeard-old species that continues to capture our imagination. A rollicking, eye-opening underwater adventure, Emperors of the Deep will shift our perception of sharks from coldblooded underwater predators to evolutionary marvels that play an integral part in maintaining the health of the world's oceans. "As illuminating as it is entertaining, this book will make you view sharks in a whole new light, revealing their mysteries without forsaking their wonder."--Dane Huckelbridge, author of No Beast So Fierce: The Terrifying True Story of the Champawat Tiger, the Deadliest Animal in History

This is an opportunity to challenge the notion that there is only one type of scientist or that scientists look and think a certain way.

Get submerged in the amazing world of sharks! Your expert host, award-winning marine biologist Dr. David Shiffman, will show you how--and why--we should protect these mysterious, misunderstood guardians of the ocean. Sharks are some of the most fascinating, most ecologically important, most threatened, and most misunderstood animals on Earth. More often feared than revered, their role as predators of the deep have earned them a reputation as a major threat to humans. But the truth is that sharks are not a danger to us--they're in danger fromus. In Why Sharks Matter, marine conservation biologist Dr. David Shiffman explains why it's crucial that we overcome our misconceptions and rise above cinematic jump scares to embrace sharks as the imperiled and elegant ocean guardians they really are. Sharing his own fascinating experiences working with sharks, Shiffman tells us * why healthy shark populations are a must for supporting ocean ecosystems--and the coastal economies that depend on them * why we're in danger of losing many shark species forever * what scientists, conservationists, and readers can do to help save these iconic predators * why so much of what you've heard about sharks and how to save them is wrong Exploring the core tenets of shark conservation science and policy, Shiffman synthesizes decades of scientific research and policymaking, weaving it into a narrative full of humor and adventure. Touching on everything from Shark Week to shark fin soup, overfishing to marine sanctuaries, Shiffman reveals why sharks are in trouble, why we should care, and how we can save them. Perfect for shark enthusiasts, Why Sharks Matteris an approachable, informative guide to the world of shark conservation and the passionate, fascinating, brilliant people who work to understand and protect our oceans. This fun read will have you looking at sharks with a fresh perspective and an understanding that the survival of sharks is crucial to the survival of another apex predator--ourselves.

Twenty metres below water, the oceanographer François Sarano came face to face with a five-and-a-half metre great white shark. Seduced by the gentle elegance of this majestic creature, Sarano experienced a profound sense of affinity with her as they swam side by side, shoulder to shoulder, eye to eye, cutting a single figure through the ocean depths. It was an experience which made him realize the depth of our ignorance of the lives of sharks, leading him to become a passionate advocate for their protection. Drawing on the latest scientific research on the biology and ethology of sharks and their exceptional characteristics, this book aims to break through the barrier of prejudice and to pay homage to their true nature. Representing a last vestige of wildness, their populations are nevertheless under threat - like so many species, they have been hunted and exploited by humans. Sarano argues for a change of mindset in which we lose ourselves in the world of the other, so that each living entity, human and non-human, can take their rightful place in the broader global ecosystem.

Over the last decade, the study of shark biology has benefited from the development, refinement, and rapid expansion of novel techniques and advances in technology. These have given new insight into the fields of shark genetics, feeding, foraging, bioenergetics, imaging, age and growth, movement, migration, habitat preference, and habitat use. This pioneering book, written by experts in shark biology, examines technologies such as autonomous vehicle tracking, underwater video approaches, molecular genetics techniques, and accelerometry, among many others. Each detailed chapter offers new insights and promises for future studies of elasmobranch biology, provides an overview of appropriate uses of each technique, and can be readily extended to other aquatic fish and marine mammals and reptiles. Including chapter authors who were pioneers in developing some of the technologies discussed in the book, this book serves as the first single-source reference with in-depth coverage of techniques appropriate for the laboratory and field study of sharks, skates, and rays. It concludes with a unique section on Citizen Science and its application to studies of shark biology. This is a must-read for any marine biologist or scientist working in the field of shark biology, as well as marine biology students and graduates.

Discusses origin, evolution, and behavior of the shark and shark attacks on human beings with documented cases. Also includes first-aid, post-attack suggestions, methods of precaution and defense.

Humans spend more time in or on the water than ever before. We love the beach, but for many people, getting in the water provokes a moment's hesitation. Shark attacks are big news events, and although the risk of shark attack on humans is incredibly low, the fact remains that human lives are lost to sharks every year. Shark Attacksexplores the tension between risk and human fear and the need to conserve sharks and protect the important ecological roles they play in our marine environments. Marine biologist Blake Chapman presents scientific information about shark biology, movement patterns, and feeding behavior. She discusses the role of fear in the way we think about sharks and the influence of the media on public perceptions. Moving first-hand accounts describe the deep and polarizing psychological impacts of shark attacks from a range of perspectives. This book is an education in thinking through these emotive events and will help readers to navigate the controversial issues around mitigating shark attacks while conserving the sharks themselves.

Gentle giant of the seas, the basking shark, the largest fish in Scottish seas, is nowadays often in the news as conservationists press for its legal protection. But at two periods in Scottish history it was hunted for the sake of its liver oil, first used as a lamp fuel, then later as a source of industrial chemicals. In very recent years hunting of the shark resumed with its fins (for the Asian market) being the main prize.

In this book, the authors present current research in the study of fish ecology and marine ecosystems. Topics discussed include the metabolic rate of marine fish in early life and its relationship to their ecological status; antioxidant defence in marine fish; teleostean fish and the genomic content; the genetic structure of the masu salmon; the catadromous freshwater eel and the taxonomic representations of marine fish from archaeological assemblages in the Beagle Channel, Argentina.

Deliberately breaking with the classical biology-centered description of marine organisms and their products, this reference emphasizes microbial technology over basic biology, setting it apart from its predecessors. As such, it systematically covers the technology behind high-value compounds for use as pharmaceuticals, nutraceuticals or cosmetics, from prospecting to production issues. Following a definition of the field, the book goes on to address all industrially important aspects of marine microbial biotechnology. The first main part contains a description of the major production organisms, from archaebacteria to cyanobacteria to algae and symbionts, including their genetic engineering. The remaining four parts look at commercially important compounds produced by these microorganisms together with their applications. Throughout, the emphasis is on technological considerations, and the future potential of these organisms or compound classes is discussed. A valuable and forward-looking resource for innovative biotechnologists in industry as well as in academia.
