Deep-Sea Pycnogonids and Crustaceans of the Americas
by Michel E. HendrickxAmong the deep-sea marine invertebrates, pycnogonids and crustaceans represent ecologically important and most diverse groups of species. Yet both are still poorly understood. Sampling and exploring operations off the west and east coast of the Americas has significantly increased in the last two decades. However such operations are very costly and limited in number and frequency. In countries like Brazil, Canada, Chile, Colombia, Costa Rica, Mexico, Peru, the United States of America, and El Salvador a large effort has been made to explore the deep-sea resources and the rich diversity of the communities, resulting in a better understanding of the natural ecosystems on both coasts of America. Pycnogonids and many groups of deep-sea crustaceans have been intensively studied, from the smallest animals, like the mostly unknown benthic copepods to the largest decapods.This book presents new and updated information on various groups of deep-sea pycnogonids and crustaceans occurring off the American continent. Offering a valuable reference resource for scientists interested in this fascinating fauna, it includes review papers and new data on the deep-sea communities occurring off the USA, Mexico, El Salvador, Costa Rica, Colombia, Chile, Peru, Brazil and Argentina, as well as in larger areas in both the East Pacific and the West Atlantic. As such it covers most of the current deep-water research in Latin America.

Deep Simplicity: Bringing Order to Chaos and Complexity
by John GribbinOver the past two decades, no field of scientific inquiry has had a more striking impact across a wide array of disciplines–from biology to physics, computing to meteorology–than that known as chaos and complexity, the study of complex systems. Now astrophysicist John Gribbin draws on his expertise to explore, in prose that communicates not only the wonder but the substance of cutting-edge science, the principles behind chaos and complexity. He reveals the remarkable ways these two revolutionary theories have been applied over the last twenty years to explain all sorts of phenomena–from weather patterns to mass extinctions. <p><p> Grounding these paradigm-shifting ideas in their historical context, Gribbin also traces their development from Newton to Darwin to Lorenz, Prigogine, and Lovelock, demonstrating how–far from overturning all that has gone before–chaos and complexity are the triumphant extensions of simple scientific laws. Ultimately, Gribbin illustrates how chaos and complexity permeate the universe on every scale, governing the evolution of life and galaxies alike.

Deep Space Propulsion
by K. F. LongThe technology of the next few decades could possibly allow us to explore with robotic probes the closest stars outside our Solar System, and maybe even observe some of the recently discovered planets circling these stars. This book looks at the reasons for exploring our stellar neighbors and at the technologies we are developing to build space probes that can traverse the enormous distances between the stars. In order to reach the nearest stars, we must first develop a propulsion technology that would take our robotic probes there in a reasonable time. Such propulsion technology has radically different requirements from conventional chemical rockets, because of the enormous distances that must be crossed. Surprisingly, many propulsion schemes for interstellar travel have been suggested and await only practical engineering solutions and the political will to make them a reality. This is a result of the tremendous advances in astrophysics that have been made in recent decades and the perseverance and imagination of tenacious theoretical physicists. This book explores these different propulsion schemes - all based on current physics - and the challenges they present to physicists, engineers, and space exploration entrepreneurs. This book will be helpful to anyone who really wants to understand the principles behind and likely future course of interstellar travel and who wants to recognizes the distinctions between pure fantasy (such as Star Trek's 'warp drive') and methods that are grounded in real physics and offer practical technological solutions for exploring the stars in the decades to come.
Deep Technology for Sustainable Fisheries and Aquaculture
by Amaj Rahimi-MidaniThis book uses real-world examples from the aquaculture industry to demonstrate how deep technology is assisting farmers and vulnerable communities. Works conducted by Poseidon-AI (a deep tech company involved in the aquaculture sector) in different countries are presented as case studies to show the positive impacts of deep tech involvement in the aquaculture sector. Primary industries, such as fisheries and aquaculture, rely heavily on labor. Furthermore, the manual practices of these farming methods increase material waste and reduce yields, resulting in higher costs and lower revenues. Poikilotherms make up the majority of aquatic animals, and environmental changes have a significant impact on them. This means that, due to climate change, farming of these animals cannot continue in the same way that it has for centuries. Artificial intelligence, machine learning, image processing, sensing, and automation are approaches that can assist these farms in dealing with rapid environmental changes while also assisting farmers in growing their businesses sustainably. This book is of interest to climate change scientists, entrepreneurs, investors, civil workers, and policymakers. Furthermore, the book is a great complimentary material for graduate students of fisheries, aquaculture, ecology, soil science, water management and environmental sciences. All national and international policymakers working in implementation of UNSDGs and sustainability, will find this book a useful read.
Deep Thinkers: Inside the Minds of Whales, Dolphins, and Porpoises
by Janet MannHumans aside, dolphins, whales, and porpoises are often considered to be the smartest creatures on Earth. Science and nature buffs are drawn to stories of their use of tools, their self-recognition, their beautiful and complex songs, and their intricate societies. But how do we know what we know, and what does it mean? In Deep Thinkers, renowned cetacean biologist Janet Mann gathers a gam of the world’s leading whale and dolphin researchers—including Luke Rendell, Hal Whitehead, and many more—to illuminate these vital questions, exploring the astounding capacities of cetacean brains. Diving into our current understanding of and dynamic research on dolphin and whale cognition, communication, and culture, Deep Thinkers reveals how incredibly sophisticated these mammals are—and how much we can learn about other animal minds by studying cetacean behavior. Through a combination of fascinating text and more than 150 beautiful and informative illustrations, chapters compare the intelligence markers of cetaceans with those of birds, bats, and primates, asking how we might properly define intelligence in nonhumans. As all-encompassing and profound as the seas in which these deep cetacean cultures have evolved, Deep Thinkers is an awesome and inspiring journey into the fathoms—a reminder of what we gain through their close study, and of what we lose when the great minds of the sea disappear.
Deep Time: A Literary History
by Noah HeringmanHow the concept of “deep time” began as a metaphor used by philosophers, poets, and naturalists in the eighteenth and nineteenth centuriesIn this interdisciplinary book, Noah Heringman argues that the concept of “deep time”—most often associated with geological epochs—began as a metaphorical language used by philosophers, poets, and naturalists of the eighteenth and nineteenth centuries to explore the origins of life beyond the written record. Their ideas about “the abyss of time” created a way to think about the prehistoric before it was possible to assign dates to the fossil record. Heringman, examining stories about the deep past by visionary thinkers ranging from William Blake to Charles Darwin, challenges the conventional wisdom that the idea of deep time came forth fully formed from the modern science of geology. Instead, he argues, it has a rich imaginative history.Heringman considers Johann Reinhold Forster and Georg Forster, naturalists on James Cook’s second voyage around the world, who, inspired by encounters with Pacific islanders, connected the scale of geological time to human origins and cultural evolution; Georges-Louis Leclerc, Comte de Buffon, who drew on travel narrative, antiquarian works, and his own fieldwork to lay out the first modern geological timescale; Blake and Johann Gottfried Herder, who used the language of fossils and artifacts to promote ancient ballads and “prehistoric song”; and Darwin’s exploration of the reciprocal effects of geological and human time. Deep time, Heringman shows, has figural and imaginative dimensions beyond its geological meaning.

Deep Time Reckoning: How Future Thinking Can Help Earth Now (One Planet)
by Vincent IalentiA guide to long-term thinking: how to envision the far future of Earth.We live on a planet careening toward environmental collapse that will be largely brought about by our own actions. And yet we struggle to grasp the scale of the crisis, barely able to imagine the effects of climate change just ten years from now, let alone the multi-millennial timescales of Earth's past and future life span. In this book, Vincent Ialenti offers a guide for envisioning the planet's far future--to become, as he terms it, more skilled deep time reckoners. The challenge, he says, is to learn to inhabit a longer now.
Deep Water
by National Commission on the BP Deepwater Horizon Oil Spill Offshore DrillingOn April 20, 2010, the Macondo well blew out, costing the lives of 11 men, and beginning a catastrophe that sank theDeepwater Horizondrilling rig and spilled nearly 5 million barrels of crude oil into the Gulf of Mexico. The spill disrupted an entire region’s economy, damaged fisheries and critical habitats, and brought vividly to light the risks of deepwater drilling for oil and gas—the latest frontier in the national energy supply. Soon after, President Barack Obama appointed a seven-member Commission to investigate the disaster, analyze its causes and effects, and recommend the actions necessary to minimize such risks in the future. The Commission’s report offers the American public and policymakers alike the fullest account available of what happened in the Gulf and why, and proposes actions—changes in company behavior, reform of government oversight, and investments in research and technology—required as industry moves forward to meet the nation’s energy needs.
Deeper Than Darwin: The Prospect for Religion in the Age of Evolution
by John F. HaughtIn his acclaimed book God After Darwin, John Haught argued that religious belief is wholly compatible with evolutionary biology. Now, in Deeper Than Darwin, he advances his argument further by saying that religious belief is even more revealing about life than Darwinism. Haught looks hard at the question of how, after Darwin, religions may plausibly claim to be bearers of truth and not just of meaning and adaptive consolation. While he assumes the fundamental correctness of evolutionary biology, he firmly rejects the non-scientific belief that evolutionary biology amounts to an adequate explanation of living phenomena. Even though Darwinism is illuminating, Haught argues, it by no means tells us everything we need to know about life, even in principle. To find the deepest, though certainly not the clearest, understandings of life and the universe, we may still profitably consult the religions of the world. Deeper Than Darwin takes up where God After Darwin left off, arguing that Darwin's vision is important and essentially correct but that we can still dig deeper in our understanding of what is going on in the life-story.
The Deepest Place: Suffering and the Formation of Hope
by Curt Thompson, MDIn the face of personal and global suffering, is it possible to live with hope rather than despair? Join psychiatrist, speaker, and award-winning author Curt Thompson as he shows us how God transforms our grief into a lasting peace that surpasses all understanding.Suffering is a defining reality of life. Yet so many of us are so focused on avoiding discomfort that we've never learned how to actually suffer. But what if we could move from anxiety to durable hope?In The Deepest Place, Thompson invites us to explore how the Apostle Paul's experience of love, secure attachment, and the deeply felt sense of God's abiding presence carried him through the challenges he faced--and how it can help us not just survive, but flourish in the presence of suffering.Combining scripture with his own professional insight, Thompson helps us discover that:Suffering can increase our sense of security rather than our fearsHope is something we form in communityFaith can grow out of anger, cynicism, and doubtPerseverance changes our brain and reshapes our imaginationListening to our bodies helps us find new hope in loss As Thompson reminds us, those who have suffered greatly, including the Apostle Paul, are able to see their stories with a new understanding of God's presence and unfailing love. Let The Deepest Place show you how to do the same.
The Deepest Well: Healing the Long-Term Effects of Childhood Adversity
by Nadine Burke HarrisA pioneering physician reveals how childhood stress leads to lifelong health problems and what we can do to break the cycle. Dr. Nadine Burke Harris was already known as a crusading physician delivering targeted care to vulnerable children. But it was Diego—a boy who had stopped growing after a sexual trauma—who galvanized her to dig deeper into the connections between toxic stress and the lifelong illnesses she was tracking among so many of her patients and their families. A survey of more than 17,000 adult patients’ “adverse childhood experiences,” or ACEs, like divorce, substance abuse, or neglect, had proved that the higher a person’s ACE score the worse their health—and now led Burke Harris to an astonishing breakthrough. Childhood stress changes our neural systems and lasts a lifetime. Through storytelling that delivers both scientific insight and moving stories of personal impact, Burke Harris illuminates her journey of discovery, from research labs nationwide to her own pediatric practice in San Francisco’s Bayview-Hunters Point. For anyone who has faced a difficult childhood, or who cares about the millions of children who do, the innovative and acclaimed health interventions outlined in The Deepest Well will represent vitally important hope for change.
The Deepest Wounds
by Thomas D. RogersInThe Deepest Wounds, Thomas D. Rogers traces social and environmental changes over four centuries in Pernambuco, Brazil's key northeastern sugar-growing state. Focusing particularly on the period from the end of slavery in 1888 to the late twentieth century, when human impact on the environment reached critical new levels, Rogers confronts the day-to-day world of farming--the complex, fraught, and occasionally poetic business of making sugarcane grow. Renowned Brazilian sociologist Gilberto Freyre, whose home state was Pernambuco, observed, "Monoculture, slavery, and latifundia--but principally monoculture--they opened here, in the life, the landscape, and the character of our people, the deepest wounds. " Inspired by Freyre's insight, Rogers tells the story of Pernambuco's wounds, describing the connections among changing agricultural technologies, landscapes and human perceptions of them, labor practices, and agricultural and economic policy. This web of interrelated factors, Rogers argues, both shaped economic progress and left extensive environmental and human damage. Combining a study of workers with analysis of their landscape, Rogers offers new interpretations of crucial moments of labor struggle, casts new light on the role of the state in agricultural change, and illuminates a legacy that influences Brazil's development even today.
