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

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.

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

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.

29,000 bathtub toys make history. It was an accident at sea in 1992 that proved the ocean currents are connected. When a cargo ship dropped a bathtub-toy-filled container into the Pacific, the little quackers bobbed along the globe's waterways, coming to rest on beaches near and far. This fictionalized account of the event is accompanied by maps charting the toys' travel pattern, a glossary, and a summary of the highly publicized event.

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.
