Download or read book Ocean Currents written by Robert Marsh and published by Elsevier. This book was released on 2021-06-30 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean Currents: Physical Drivers in a Changing World opens with a general introduction to the character, measurement, and simulation of ocean currents, leading to a physical and dynamical framework for understanding the wide variety of flows encountered in the oceans. The book comprises chapters covering distinct aspects of contrasting ocean currents: broad and slow, deep and shallow, narrow and swift, large scale and small scale, low latitudes and high latitudes, and moving in horizontal and vertical planes. Through this approach the authors cover a wide range of applications, from local to global, with considerable geographical context. Provides analyses of ocean observations and numerical model simulations, highlighting the pathways and drift associated with ocean currents, around the World Ocean, linked to online exercises for instructors and students that extend this perspective Presents applications to natural phenomena, showing how ocean currents shape marine ecosystems, helping researchers understand the distribution and adaptation of life in the oceans Addresses societal challenges, specifically how ocean currents disperse pollutants (e.g. plastic) from coastal sources and how the global ocean circulation is central to our changing climate, helping students and researchers develop an interdisciplinary approach to global environmental change
Book Synopsis Measuring Ocean Currents by : Antony Joseph
Download or read book Measuring Ocean Currents written by Antony Joseph and published by Newnes. This book was released on 2013-08-12 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measuring Ocean Currents: Tools, Technologies, and Data covers all major aspects of ocean current measurements in view of the implications of ocean currents on changing climate, increasing pollution levels, and offshore engineering activities. Although more than 70% of the Earth is covered by ocean, there is limited information on the countless fine- to large-scale water motions taking place within them. This book fills that information gap as the first work that summarizes the state-of-the-art methods and instruments used for surface, subsurface, and abyssal ocean current measurements. Readers of this book will find a wealth of information on Lagrangian measurements, horizontal mapping, imaging, Eulerian measurements, and vertical profiling techniques. In addition, the book describes modern technologies for remote measurement of ocean currents and their signatures, including HF Doppler radar systems, satellite-borne sensors, ocean acoustic tomography, and more. Crucial aspects of ocean currents are described in detail as well, including dispersion of effluents discharged into the sea and transport of beneficial materials—as well as environmentally hazardous materials—from one region to another. The book highlights several important practical applications, showing how measurements relate to climate change and pollution levels, how they affect coastal and offshore engineering activities, and how they can aid in tsunami detection. Coverage of measurement, mapping and profiling techniques Descriptions of technologies for remote measurement of ocean currents and their signatures Reviews crucial aspects of ocean currents, including special emphasis on the planet-spanning thermohaline circulation, known as the ocean's "conveyor belt," and its crucial role in climate change
Download or read book Global Currents written by Tasha G Oren and published by Rutgers University Press. This book was released on 2004-09-02 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rhetoric about media technology tends to fall into two extreme categories: unequivocal celebration or blanket condemnation. This is particularly true in debate over the clash of values when first world media infiltrate third world audiences. Bringing together the best new work on contemporary media practices, technologies, and policies, the essayists in Global Currents argue that neither of these extreme views accurately represents the role of media technology today. New ways of thinking about film, television, music, and the internet demonstrate that it is not only media technologies that affect the cultures into which they are introduced—it is just as likely that the receiving culture will change the media. Topics covered in the volume include copyright law and surveillance technology, cyber activism in the African Diaspora, transnational monopolies and local television industries, the marketing and consumption of “global music,” “click politics” and the war on Afghanistan, the techno-politics of distance education, artificial intelligence and global legal institutions, and traveling and “squatting” in digital space. Balanced between major theoretical positions and original field research, the selections address the political and cultural meanings that surround and configure new technologies.

Book Synopsis The Great Ocean Conveyor by : Wallace Broecker
Download or read book The Great Ocean Conveyor written by Wallace Broecker and published by Princeton University Press. This book was released on 2010-01-11 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploring the link between the ocean's currents and rapid climate change Wally Broecker is one of the world's leading authorities on abrupt global climate change. More than two decades ago, he discovered the link between ocean circulation and climate change, in particular how shutdowns of the Great Ocean Conveyor—the vast network of currents that circulate water, heat, and nutrients around the globe—triggered past ice ages. Today, he is among the researchers exploring how our planet's climate system can abruptly "flip-flop" from one state to another, and who are weighing the implications for the future. In The Great Ocean Conveyor, Broecker introduces readers to the science of abrupt climate change while providing a vivid, firsthand account of the field's history and development. Could global warming cause the conveyor to shut down again, prompting another flip-flop in climate? What were the repercussions of past climate shifts? How do we know such shifts occurred? Broecker shows how Earth scientists study ancient ice cores and marine sediments to probe Earth's distant past, and how they blend scientific detective work with the latest technological advances to try to predict the future. He traces how the science has evolved over the years, from the blind alleys and wrong turns to the controversies and breathtaking discoveries. Broecker describes the men and women behind the science, and reveals how his own thinking about abrupt climate change has itself flip-flopped as new evidence has emerged. Rich with personal stories and insights, The Great Ocean Conveyor opens a tantalizing window onto how Earth science is practiced.

Download or read book Contemporary Art written by Terry Smith and published by Laurence King. This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contemporary Art: World Currents argues that, in recent decades, a worldwide shift from modern to contemporary art has occurred. This has not, however, been a uniform change from one phase or styles in the history of art to another. Rather artists everywhere have embraced the contemporary world's teeming multiplicity, its proliferating differences and its challenging complexities. Alongside more that 370 key works, Terry Smith shows how contemporary art achieved definitive force in the markets and museums of the major art centres during the 1980s and then became a global phenomenon as artworlds everywhere began to connect more closely. New communicative technologies and expanding social media are now shaping the future of art. This book breaks new ground in tracing how modern, traditional and indigenous art became contemporary in each cultural region of the world. Diversity - the contemporaneity of difference - not a convergence towards sameness, Smith argues, is what makes today's art contemporary.

Download or read book Currents written by Jane Petrlik Smolik and published by Charlesbridge Publishing. This book was released on 2015-09-08 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This middle-grade historical novel follows three young girls living very different lives who are connected by one bottle that makes two journeys across the ocean. It's 1854 and eleven-year-old Bones is a slave on a Virginia plantation. When she finds her name in the slave-record book, she rips it out, rolls it up, and sets it free, corked inside a bottle alongside the carved peach pit heart her long-lost father made for her. Across the Atlantic on the Isle of Wight, motherless Lady Bess Kent and her sister discover Bones's bottle half-buried on the beach. Leaving Bones's name where it began and keeping the peach pit heart for herself, Bess hides her mother's pearl-encrusted cross necklace in the bottles so her scheming stepmother, Elsie, can't sell it off like she's done with other family heirlooms. When Harry, a local stonemason's son, takes the fall for Elsie's thefts, Bess works with her seafaring friend, Chap, to help him escape. She gives the bottle to Harry and tells him to sell the cross. Back across the Atlantic in Boston, Mary Margaret Casey and her father are at the docks when Mary Margaret spies something shiny. Her father fishes it out of the water, and they use the cross to pay for a much needed doctor's visit for Mary Margaret's ailing sister. As Bess did, Mary Margaret leaves Bones's name where it belongs. An epilogue returns briefly to each girl, completing the circle of the three unexpectedly interconnected lives.
Book Synopsis Shifting Currents by : Karen Eva Carr
Download or read book Shifting Currents written by Karen Eva Carr and published by Reaktion Books. This book was released on 2022-07-18 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: A deep dive into the history of aquatics that exposes centuries-old tensions of race, gender, and power at the root of many contemporary swimming controversies. Shifting Currents is an original and comprehensive history of swimming. It examines the tension that arose when non-swimming northerners met African and Southeast Asian swimmers. Using archaeological, textual, and art-historical sources, Karen Eva Carr shows how the water simultaneously attracted and repelled these northerners—swimming seemed uncanny, related to witchcraft and sin. Europeans used Africans’ and Native Americans’ swimming skills to justify enslaving them, but northerners also wanted to claim water’s power for themselves. They imagined that swimming would bring them health and demonstrate their scientific modernity. As Carr reveals, this unresolved tension still sexualizes women’s swimming and marginalizes Black and Indigenous swimmers today. Thus, the history of swimming offers a new lens through which to gain a clearer view of race, gender, and power on a centuries-long scale.
Book Synopsis Deep Currents and Rising Tides by : John Garofano
Download or read book Deep Currents and Rising Tides written by John Garofano and published by Georgetown University Press. This book was released on 2013-04-29 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Indian Ocean region has rapidly emerged as a hinge point in the changing global balance of power and the geographic nexus of economic and security issues with vital global consequences. The security of energy supplies, persistent poverty and its contribution to political extremism, piracy, and related threats to seaborne trade, competing nuclear powers, and possibly the scene of future clashes between rising great powers India and China—all are dangers in the waters or in the littoral states of the Indian Ocean region. This volume, one of the first attempts to treat the Indian Ocean Region in a coherent fashion, captures the spectrum of cooperation and competition in the Indian Ocean Region. Contributors discuss points of cooperation and competition in a region that stretches from East Africa, to Singapore, to Australia, and assess the regional interests of China, India, Pakistan, and the United States. Chapters review possible “red lines” for Chinese security in the region, India’s naval ambitions, Pakistan’s maritime security, and threats from non-state actors—terrorists, pirates, and criminal groups—who challenge security on the ocean for all states. This volume will interest academics, professionals, and researchers with interests in international relations, Asian security, and maritime studies.

Book Synopsis The Discovery of Global Warming by : Spencer R. Weart
Download or read book The Discovery of Global Warming written by Spencer R. Weart and published by Harvard University Press. This book was released on 2003 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2001 a panel representing virtually all the world's governments and climate scientists announced that they had reached a consensus: the world was warming at a rate without precedent during at least the last ten millennia, and that warming was caused by the buildup of greenhouse gases from human activity. The consensus itself was at least a century in the making. The story of how scientists reached their conclusion--by way of unexpected twists and turns and in the face of formidable intellectual, financial, and political obstacles--is told for the first time in The Discovery of Global Warming. Spencer R. Weart lucidly explains the emerging science, introduces us to the major players, and shows us how the Earth's irreducibly complicated climate system was mirrored by the global scientific community that studied it. Unlike familiar tales of Science Triumphant, this book portrays scientists working on bits and pieces of a topic so complex that they could never achieve full certainty--yet so important to human survival that provisional answers were essential. Weart unsparingly depicts the conflicts and mistakes, and how they sometimes led to fruitful results. His book reminds us that scientists do not work in isolation, but interact in crucial ways with the political system and with the general public. The book not only reveals the history of global warming, but also analyzes the nature of modern scientific work as it confronts the most difficult questions about the Earth's future. Table of Contents: Preface 1. How Could Climate Change? 2. Discovering a Possibility 3. A Delicate System 4. A Visible Threat 5. Public Warnings 6. The Erratic Beast 7. Breaking into Politics 8. The Discovery Confirmed Reflections Milestones Notes Further Reading Index Reviews of this book: A soberly written synthesis of science and politics. --Gilbert Taylor, Booklist Reviews of this book: Charting the evolution and confirmation of the theory [of global warming], Spencer R. Weart, director of the Center for the History of Physics of the American Institute of Physics, dissects the interwoven threads of research and reveals the political and societal subtexts that colored scientists' views and the public reception their work received. --Andrew C. Revkin, New York Times Book Review Reviews of this book: It took a century for scientists to agree that gases produced by human activity were causing the world to warm up. Now, in an engaging book that reads like a detective story, physicist Weart reports the history of global warming theory, including the internal conflicts plaguing the research community and the role government has had in promoting climate studies. --Publishers Weekly Reviews of this book: It is almost two centuries since the French mathematician Jean Baptiste Fourier discovered that the Earth was far warmer than it had any right to be, given its distance from the Sun...Spencer Weart's book about how Fourier's initially inconsequential discovery finally triggered urgent debate about the future habitability of the Earth is lucid, painstaking and commendably brief, packing everything into 200 pages. --Fred Pearce, The Independent Reviews of this book: [The Discovery of Global Warming] is a well-written, well-researched and well-balanced account of the issues involved...This is not a sermon for the faithful, or verses from Revelation for the evangelicals, but a serious summary for those who like reasoned argument. Read it--and be converted. --John Emsley, Times Literary Supplement Reviews of this book: This is a terrific book...Perhaps the finest compliment I could give this book is to report that I intend to use it instead of my own book...for my climate class. The Discovery of Global Warming is more up-to-date, better balanced historically, beautifully written and, not least important, short and to the point. I think the [Intergovernmental Panel on Climate Change] needs to enlist a few good historians like Weart for its next assessment. --Stephen H. Schneider, Nature Reviews of this book: This short, well-written book by a science historian at the American Institute of Physics adds a serious voice to the overheated debate about global warming and would serve as a great starting point for anyone who wants to better understand the issue. --Maureen Christie, American Scientist Reviews of this book: I was very pleasantly surprised to find that Spencer Weart's account provides much valuable and interesting material about how the discipline developed--not just from the perspective of climate science but also within the context of the field's relation to other scientific disciplines, the media, political trends, and even 20th-century history (particularly the Cold War). In addition, Weart has done a valuable service by recording for posterity background information on some of the key discoveries and historical figures who contributed to our present understanding of the global warming problem. --Thomas J. Crowley, Science Reviews of this book: Weart has done us all a service by bringing the discovery of global warming into a short, compendious and persuasive book for a general readership. He is especially strong on the early days and the scientific background. --Crispin Tickell, Times Higher Education Supplement A Capricious Beast Ever since the days when he had trudged around fossil lake basins in Nevada for his doctoral thesis, Wally Broecker had been interested in sudden climate shifts. The reported sudden jumps of CO2 in Greenland ice cores stimulated him to put this interest into conjunction with his oceanographic interests. The result was a surprising and important calculation. The key was what Broecker later described as a "great conveyor belt'"of seawater carrying heat northward. . . . The energy carried to the neighborhood of Iceland was "staggering," Broecker realized, nearly a third as much as the Sun sheds upon the entire North Atlantic. If something were to shut down the conveyor, climate would change across much of the Northern Hemisphere' There was reason to believe a shutdown could happen swiftly. In many regions the consequences for climate would be spectacular. Broecker was foremost in taking this disagreeable news to the public. In 1987 he wrote that we had been treating the greenhouse effect as a 'cocktail hour curiosity,' but now 'we must view it as a threat to human beings and wildlife.' The climate system was a capricious beast, he said, and we were poking it with a sharp stick. I found the book enjoyable, thoughtful, and an excellent introduction to the history of what may be one of the most important subjects of the next one hundred years. --Clark Miller, University of Wisconsin The Discovery of Global Warming raises important scientific issues and topics and includes essential detail. Readers should be able to follow the discussion and emerge at the end with a good understanding of how scientists have developed a consensus on global warming, what it is, and what issues now face human society. --Thomas R. Dunlap, Texas A&M University
