    "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"--

    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.

    "Sharks have been fighting for their lives for 500 million years and are under dire threat today. They are the longest surviving vertebrate on Earth, outlasting multiple mass extinction events that decimated life on the planet. How did they thrive so long? By developing superpower-like abilities that allowed them to ascend to the top of the oceanic food chain. Yet they often found themselves in the shadows of larger, more formidable killers--and they not only survived, but also took their crown as the king of the sea. ... Because of recent technological breakthroughs, scientists' understanding of sharks has taken a quantum leap forward in the last decade. John Long has been on the cutting edge of this research and in this [book] weaves a fully updated and unexpected tale of shark's extraordinary evolutionary adventure"--

    Mangroves are considered the ¿wonder florä distributed in the tropics, subtropics, and warm temperate latitudes. Aside from protecting the coastal marine communities, mangroves also serve as a haven for aquatic and terrestrial fauna, actively participate in energy dynamics, recycle nutrients, filter waste, and support the livelihood of coastal communities. This makes the mangrove ecosystem crucial to the well-being of the planet. This book, written by experts, provides invaluable insights into mangroves of the Niger Delta, the relationship between mangrove recruitment and thrombolytic development, deforestation and sustainability, mangrove health assessment, ecosystem-based coastal protection, and conservation through ecotourism. This book on mangrove biology, ecosystem, and conservation is an invaluable resource for every mangrove enthusiast.

  • - The World in the Ocean
    af James Bradley
    173,95 kr.

    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.

From plainfin midshipman fish, whose swim-bladder drumming is loud enough to keep houseboat-dwellers awake, to the syntax of whalesong; from the deafening crackle of snapping shrimp, to the seismic resonance of underwater earthquakes and volcanoes; sound plays a vital role in feeding, mating, parenting, navigating, and warning-even in animals that we never suspected of acoustic ability. Meanwhile, we jump in our motorboats and cruise ships, oblivious to the impact below us. Our lifestyle is fueled by oil in growling tankers and furnished by goods that travel in massive container ships. Our seas echo with human-made sound, but we are just learning of the repercussions of anthropogenic noise on the marine world's delicate acoustic ecosystems-masking mating calls, chasing animals from their food, and even wounding creatures, from plankton to lobsters. With intimate and artful prose, 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"--

    The crash of 19 stocks of Fraser River sockeye over a 15 year period forced the Canadian government to close all fishing from 2007 to 2009. The Canadian government, desperate for answers, or at least looking for a way to deflect criticism, struck an inquiry led by justice Bruce Cohen that would last over a year. The decline was quick and dramatic. It looked like Fraser river sockeye populations were going extinct. For more than 20 years, Alexandra Morton, an independent biologist, has been a vocal campaigner against open net pen fish farms. Her research and subsequent publications outline a case that sea lice and disease from the farms have spread to wild salmon populations. She argues that open net fish farms is the source of the problem. But instead of embracing her findings, government and industry have vilified the whistleblower and tried many things to silence her. Finally, after nearly a year of hearings, Morton appeared at the inquiry for two days. The battle lines were quickly drawn and the inquiry became more like a trial of a witness than an information gathering process. It is rare that partnerships between government and corporate interests are acknowledged in public. It's even more rare to see it in action.Includes an extensive bibliography along with over 50 photos in colour and black and white.
