"The beauty of the apex predator captured up close and unflinchingly. A global shift from fright to endearment is happening, and the world is falling in love with sharks as risk of their endangerment increases. Mike Coots, who was nearly killed by a tiger shark as a teenager and has since dedicated his life to capturing and sharing sharks' beauty and indispensable role in a healthy ocean, gets up close and very personal with the magnificent creatures, presenting his unique perspective through portraits exposing both their brawn and their brains. Traveling the world (Hawaii, Mexico, New Zealand, Bahamas, and Maldives), free diving and scuba diving, often with no cage, Coots has recorded Tigers, Great Hammerheads, rare Oceanic White Tips, Lemons, Silvertips, Caribbean Reef Sharks, and massive Great Whites, as big as fourteen feet in length. Big, bold, and beautiful, extraordinary portraits of some of the ocean's largest sharks present a fresh photographic narrative of what it's like being apex. Coots anthropomorphizes the giant fish, with amazingly detailed and unexpectedly intimate images, filled with the stunning character of each species revealed marvelously."--

"From New York Times bestselling author Susan Casey, an awe-inspiring portrait of the mysterious world beneath the waves, and the men and women who seek to uncover its secrets For all of human history, the deep ocean has been a source of wonder and terror, an unknown realm that evoked a singular, compelling question: What's down there? Unable to answer this for centuries, people believed the deep was a sinister realm of fiendish creatures and deadly peril. But now, cutting-edge technologies allow scientists and explorers to dive miles beneath the surface, and we are beginning to understand this strange and exotic underworld: A place of soaring mountains, smoldering volcanoes, and valleys 7,000 feet deeper than Everest is high, where tectonic plates collide and separate, and extraordinary life forms operate under different rules. Far from a dark void, the deep is a vibrant realm that's home to pink gelatinous predators and shimmering creatures a hundred feet long and ancient animals with glass skeletons and sharks that live for half a millennium-among countless other marvels. Susan Casey is our premiere chronicler of the aquatic world. For The Underworld she traversed the globe, joining scientists and explorers on dives to the deepest places on the planet, interviewing the marine geologists, marine biologists, and oceanographers who are searching for knowledge in this vast unseen realm. She takes us on a fascinating journey through the history of deep-sea exploration, from the myths and legends of the ancient world to storied shipwrecks we can now reach on the bottom, to the first intrepid bathysphere pilots, to the scientists who are just beginning to understand the mind-blowing complexity and ecological importance of the quadrillions of creatures who live in realms long thought to be devoid of life. Throughout this journey, she learned how vital the deep is to the future of the planet, and how urgent it is that we understand it in a time of increasing threats from climate change, industrial fishing, pollution, and the mining companies that are also exploring its depths. The Underworld is Susan Casey's most beautiful and thrilling book yet, a gorgeous evocation of the natural world and a powerful call to arms"--

Long hailed as a classic of American nature writing, Henry Beston's eloquent chronicle of a solitary year spent on a Cape Cod beach was written in longhand at the kitchen table, in a little room overlooking the North Atlantic and the dunes. In 1926 Beston retreated to the outer beach at Eastham in search of peace and solitude. What began as a two-week stay lengthened into a year spent keenly observing the rhythm of the seasons and life on the Great Beach. The Outermost House played a part in establishing the Cape Code National Seashore and has profoundly influenced subsequent nature writers, including Rachel Carson, Joseph Wood Krutch, Annie Dillard, and Barry Lopez. This Warbler Classics edition includes an essay by Allan Burns on the art and legacy of The Outermost House as well as a detailed biographical timeline.

This book recognizes the fact that the vessels' intended operational profile may vary as some vessels are intended to operate with the assistance of an ice breaker and others are intended to operate independently. The guidance provided in this book is proposed to apply to all vessels that are designed, equipped and intended to operate in low-temperature environments. Special attention is given to those vessels operating for extended periods in the Arctic regions, as this presents specific and unique challenges for vessels and crew members. The application of the guidance in this book is optional. When a vessel is designed, equipped, built and surveyed in accordance with the relevant class rules, and when found satisfactory during class notation survey, a classification notation may be granted which demonstrates the vessel's compliance with the appropriate class requirements for vessels operating in low-temperature environments. Those vessels that are designed to meet the requirements of an ice class are typically required to meet specific class rules around ¿strengthening for navigation in ice¿ or other equivalent and recognized ice class rules. Accordingly, this book also provides guidance related to the requirements which address the duration of emergency electrical power. This extended emergency power duration is expressed in hours and may be appended to the base optional class notations. To provide as much context as possible, this book refers to the most relevant international regulations and standards that are considered to be applicable. It is recommended that readers of this book refer to the most recent text of those regulations and standards when seeking to apply the guidance set out herein, as it is the intent of the book to remain consistent with the pertinent international regulations and standards developed by the global maritime industry.

A captivating exploration of how underwater animals tap into sound to survive, and a clarion call for humans to address the ways we invade these critical soundscapes - from an award-winning science writer.For centuries humans ignored sound in the 'silent world' of the ocean, assuming that what we couldn't perceive, didn't exist. But we couldn't have been more wrong. Marine scientists now have the technology to record and study the complex interplay of the myriad sounds in the sea. Finally, we can trace how sounds travel with the currents, bounce from the seafloor and surface, bend with temperature, and even saltiness; how sounds help marine life survive; and how human noise can transform entire marine ecosystems.In Sing Like Fish, award-winning science journalist Amorina Kingdon synthesises historical discoveries with the latest research in a clear and compelling portrait of this sonic undersea world. From plainfin midshipman fish, whose swim-bladder drumming is so loud it keeps houseboat-dwellers awake, to the syntax of whalesong, from the deafening crackle of snapping shrimp, to underwater earthquakes and volcanoes, sound plays a vital role in feeding, mating, parenting, navigating, and warning. Meanwhile, our seas also echo with human-made sound, and we are only just learning how these pervasive noises can mask mating calls, chase animals from their food, and even wound creatures.Intimate and artful, Sing Like Fish tells a uniquely complete story of ocean animals' submerged sounds, envisions a quieter future, and offers a profound new understanding of the world below the surface.

Beneath our feet lies a hidden world, teeming with life adapted to survive in the most extreme conditions imaginable. In the crushing darkness of subsurface oceans and the frozen grip of permafrost, microscopic organisms thrive in a realm beyond our everyday experience. This is the story of these extremophiles, the microbial pioneers of the deep Earth. Subsurface Oceans: A Cradle of Life in the Darkness Imagine a vast ocean, not of salty water under an open sky, but trapped within the Earth's crust. These subsurface oases, found kilometres beneath the surface, are remnants of ancient seawater or even primordial soup trapped during the planet's formation. Here, in perpetual darkness and under immense pressure, extremophiles adapted to a chemosynthetic existence. They harness the energy from chemical reactions of elements like hydrogen sulfide and methane, thriving in a world devoid of sunlight. Permafrost: Frozen in Time, Alive with Possibility The vast permafrost regions of the Arctic and Antarctic hold another secret realm: frozen pockets of liquid water and brines trapped within the icy grip. These microscopic oases, often mere drops or thin films, are home to a unique community of microorganisms adapted to survive in sub-zero temperatures. From bacteria that produce antifreeze proteins to archaea that thrive in high salt concentrations, permafrost microbes defy the limits of what we thought possible for life. A Window into the Origins of Life and BeyondStudying these extremophiles is not just about understanding life in the most challenging environments on Earth. It offers a glimpse into the potential for life beyond our planet. The conditions found in subsurface oceans and permafrost are similar to those suspected to exist on Mars, Europa, and other moons in our solar system. By understanding how extremophiles survive and thrive in these harsh environments, we gain valuable insights into the possibility of extraterrestrial life. The Hidden Realm: A story of resilience, adaptation, and the endless potential of life. As we delve deeper into these microbial frontiers, we rewrite our understanding of what it means to be alive and unlock the secrets of life's perseverance in the most unexpected corners of our planet and beyond.

Isabella Lövin's The Oceanic Feeling: On the Need for a New Narrative, is a unique document of a life spent on the front lines of the climate battle, and at the negotiating tables where the future of our planet is decided.The Swedish investigative journalist who became a member of the European Parliament and then served for seven years in government, five of those as Deputy Prime Minister and Climate Minister, takes us on a journey behind the scenes of climate and global ocean policy making.Some may remember the viral picture of her signing the Swedish climate law in 2017. As Donald Trump just had signed a regressive executive order limiting women's sexual and reproductive rights surrounded by only men, she by contrast signed progressive climate legislation surrounded by women.Deeply concerned about the shrinking confidence in democracy Lövin offers a pedagogic and hopeful account of the fact that change can happen, if there is a will and a vision. But she also recognizes the main reason why humanity is not acting on the many global crises: a narrative of egoism and individualism. A truer and much more positive story can be found when we recognize "The Oceanic Feeling"; a deep connection with nature, people and the miraculous web of life on the planet; putting empathy, responsibility and awe at the center of what it is to be human.How, Lövin asks us, can we convert the world to this new, healthier narrative?

Now in paperback: a "deeply researched and reported" (San Francisco Chronicle) exploration of sea level rise in California that "breathes exquisite detail and dialogue" (Science Magazine) into the subject."Viscerally urgent, thoroughly reported, and compellingly written—a must-read for our uncertain times." —Ed Yong, author of An Immense World"When do seawalls make sense? And when is it better to give in to the tides? [...] In California Against the Sea, Xia [...] writes about the difficult realities of trying to incorporate fairness into our tally of costs and benefits." —The New YorkerAlong California's 1,200-mile coastline, the overheated Pacific Ocean is rising and pressing in, imperiling both wildlife and the maritime towns and cities that 27 million people call home. In California Against the Sea, Los Angeles Times coastal reporter Rosanna Xia asks: As climate chaos threatens the places we love so fiercely, will we finally grasp our collective capacity for change?Xia, a Pulitzer Prize finalist, investigates the impacts of engineered landscapes, the market pressures of development, and the ecological activism and political scrimmages that have carved our contemporary coastline—and foretell even greater changes to our shores. From the beaches of the Mexican border up to the sheer-cliffed North Coast, the voices of Indigenous leaders, community activists, small-town mayors, urban engineers, and tenacious environmental scientists commingle. Together, they chronicle the challenges and urgency of forging a climate-wise future. Xia's investigation takes us to Imperial Beach, Los Angeles, Pacifica, Marin City, San Francisco, and beyond, weighing the rivaling arguments, agreements, compromises, and visions governing the State of California’s commitment to a coast for all. Through graceful reportage, she charts how the decisions we make today will determine where we go tomorrow: headlong into natural disaster, or toward an equitable refashioning of coastal stewardship.

This book focuses, in seven chapters, on the perspectives and solutions that different research groups offer to try to address problems related to SDG 14: Life Below Water. The different objectives developed in SDG 14 are treated independently, with an attempt to give a global vision of the issues. The mechanism used to select the book's content was through an Artificial Intelligence program, choosing articles related to the topics by means of keywords. The program selected those articles, and those that were not related to the topic or did not focus on SDG 14 were discarded by a subject matter expert. Obviously, the selection was partial and the entire subject is not covered, but the final product gives a very solid idea of how to orient ourselves to delve deeper into the topic of SDG 14 using published chapters and articles. The AI program itself selected the text of these contributions to show the progress in different topics related to SDG 14. This mode of operation will allow specialists (and non-specialists) to collect useful information for their specific research purposes in a short period of time. At a time when information is essential in order to move quickly by providing concrete answers to complex problems, this type of approach will become essential for researchers, especially for a subject as vast as SDG 14.

"From a marine biologist and co-founder of Minorities in Shark Sciences, a ... debut memoir: the uplifting story of a young Black scientist's challenging journey to flourish outside the traditional confines of academia, inspired by her innate connection to nature's most misunderstood animal: the shark"--

In this thrilling work--a blend of history, science, nature writing, and environmentalism--acclaimed writer James Bradley plunges into the unknown to explore the deepest recesses of the natural world.Seventy-one percent of the earth's surface is ocean. These waters created, shaped, and continue to sustain not just human life, but all life on Planet Earth, and perhaps beyond it. They serve as the stage for our cultural history--driving human development from evolution through exploration, colonialism, and the modern era of global leisure and trade. They are also the harbingers of the future--much of life on Earth cannot survive if sea levels are too low or too high, temperatures too cold or too warm. Our oceans are vast spaces of immense wonder and beauty, and our relationship to them is innate and awe inspired.Deep Water is both a lyrically written personal meditation and an intriguing wide-ranging reported epic that reckons with our complex connection to the seas. It is a story shaped by tidal movements and deep currents, lit by the insights of philosophers, scientists, artists and other great minds. Bradley takes readers from the atomic creation of the oceans, to the wonders within, such as fish migrations guided by electromagnetic sensing. He describes the impacts of human population shifts by boat andspeaks directly and uncompromisingly to the environmental catastrophe that is already impacting our lives. It is also a celebration of the ocean's glories and the extraordinary efforts of the scientists and researchers who are unlocking its secrets. These myriad strands are woven together into a tapestry of life that captures not only our relationship with the planet, but our past, and perhaps most importantly, what lies ahead for us.A brilliant blend of Robert MacFarlane's Underland, Susan Casey's The Underworld, and Simon Winchester's Pacific and The Atlantic, Deep Water taps into the essence of our plant and who we are.
