Discovering the Trigger for Abrupt 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.

Volume III, Geology
Volume 3 of Gulf of Mexico Origin, Waters, and Biota; a series edited by John W. Tunnell Jr., Darryl L. Felder, and Sylvia A. Earle A continuation of the landmark scientific reference series from the Harte Research Institute for Gulf Of Mexico Studies, this volume provides the most up-to-date systematic, cohesive, and comprehensive description of the geology of the Gulf of Mexico basin. The book’s six sections address the Gulf’s origin (including petroleum resources), processes (including climate change), and coral reefs. Knowledge about the foundation of the ocean environment remains vital to the understanding of the mineral and marine resources of the Gulf as well as the increasing effects of sedimentation and global warming. With this volume, much of the information necessary for a full view of the geology of the Gulf in the U.S., Mexico, and Cuba that was previously sequestered in the files of industry or government has been made more readily available for scientists, researchers, and students. It provides valuable synthesis and interpretation, representing nearly everything known about the geology of the Gulf of Mexico in the early twenty-first century. Four years in the making, this monumental compilation is both a lasting record of the current state of knowledge and the starting point for a new millennium of study.
The Korean Wave in the Age of Social Media
Collectively known as Hallyu, Korean music, television programs, films, online games, and comics enjoy global popularity, thanks to new communication technologies. In recent years, Korean popular culture has also become the subject of academic inquiry. Whereas the Hallyu’s impact on Korea’s national image and domestic economy, as well as on transnational cultural flows, have received much scholarly attention, there has been little discussion of the role of social media in Hallyu’s propagation.
Cultural Landscapes at Waconda Lake, Kansas
Most people would not consider north central Kansas’ Waconda Lake to be extraordinary. The lake, completed in 1969 by the federal Bureau of Reclamation for flood control, irrigation, and water supply purposes, sits amid a region known—when it is thought of at all—for agriculture and, perhaps to a few, as the home of "The World’s Largest Ball of Twine" (in nearby Cawker City). Yet, to the native people living in this region in the centuries before Anglo incursion, this was a place of great spiritual power and mystic significance. Waconda Spring, now beneath the waters of the lake, was held as sacred, a place where connection with the spirit world was possible. Nearby, a giant snake symbol carved into the earth by native peoples—likely the ancestors of today’s Wichitas—signified a similar place of reverence and totemic power. All that began to change on July 6, 1870, when Charles DeRudio, an officer in the 7th U.S. Cavalry who had served with George Armstrong Custer, purchased a tract on the north bank of the Solomon River—a tract that included Waconda Spring. DeRudio had little regard for the sacred properties of his acreage; instead, he viewed the mineral spring as a way to make money. In Holy Ground, Healing Water: Cultural Landscapes at Waconda Springs, Kansas, anthropologist Donald J. Blakeslee traces the usage and attendant meanings of this area, beginning with prehistoric sites dating between AD 1000 and 1250 and continuing to the present day. Addressing all the sites at Waconda Lake, regardless of age or cultural affiliation, Blakeslee tells a dramatic story that looks back from the humdrum present through the romantic haze of the nineteenth century to an older landscape, one that is more wonderful by far than what the modern imagination can conceive.
Geography, Ideology, and Transgression
In Place/Out of Place was first published in 1996. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.
What is the relationship between place and behavior? In this fascinating volume, Tim Cresswell examines this question via "transgressive acts" that are judged as inappropriate not only because they are committed by marginalized groups but also because of where they occur.
In Place/Out of Place seeks to illustrate the ways in which the idea of geographical deviance is used as an ideological tool to maintain an established order. Cresswell looks at graffiti in New York City, the attempts by various "hippie" groups to hold a free festival at Stonehenge during the summer solstices of 1984–86, and the Greenham Common Women's Peace Camp in Berkshire, England. In each of the cases described, the groups involved were designated as out of place both by the media and by politicians, whose descriptions included an array of images such as dirt, disease, madness, and foreignness.
Cresswell argues that space and place are key factors in the definition of deviance and, conversely, that space and place are used to construct notions of order and propriety. In addition, whereas ideological concepts being expressed about what is good, just, and appropriate often are delineated geographically, the transgression of these delineations reveals the normally hidden relationships between place and ideology-in other words, the "out-of-place" serves to highlight and define the "in-place." By looking at the transgressions of the marginalized, Cresswell argues, we can gain a novel perspective on the "normal" and "taken-for-granted" expectations of everyday life. The book concludes with a consideration of the possibility of a "politics of transgression," arguing for a link between the challenging of spatial boundaries and the possibility of social transformation.
Tim Cresswell is currently lecturer in geography at the University of Wales.
Language, Politics, and the Environment
Marking and Making Place
Landscapes all over the world are inscribed with enduring physical marks. Socially constructed and engaged, landscape inscriptions (monuments, roads, gardens, rock-art) are foci of social experience and as such are symbolic expressions that mold and facilitate the transmission of ideas. Through inscription, landscapes become social arenas where the past is memorialized, where personal roots, ambitions, and attachments are laid, and where futures unfold. Inscribed Landscapes explores the role of inscription in the social construction of place, power, and identity. Bringing together twenty-one scholars across a range of fields--primarily archaeology, anthropology, and geography--it discusses how social codes and hegemonic practices have resulted in the production of particular senses of place, exploring the physical and metaphysical marking of place as a means of accessing social history. Two major conceptual themes link the chapters of this book: social participation and resistance. Participation involves interrelationships between people and place, the way inscribed environments and social experience intertwine; resistance relates to the rejection of modes of domination and their inscription in the landscape. The volume explores these themes in three parts: the first focuses on rock-art, the second on monuments, and the third describes how the physical and metaphysical articulate to inscribe places with meaning.
Population growth and the drop in the returns from the major cash crop (coffee) for small farmers are the main drivers that have influenced the farming systems and mobility of farmers in the Western Highlands of Cameroon. The main objective of the research that led to this book was to determine the interactions between farming systems and human mobility in this region of Cameroon. A comparative study was conducted through household and field surveys in three villages and conceptualized based on the systems approach. The different types of mobility were influenced by household social factors, the quest for ëhigh valuedí farm plots and hired labour. Urban-rural migration contributed to occupation diversification and social mobility. The sustainability factor was a function of land use intensity, intensity of off-farm inputs, the household adjustment factor and mobility of the household. The sacred groves were rich in plant diversity of varied ecological and economic importance. Nitrogen mining was common at all levels of the farming system. These determinants and types of mobility claims are pertinent to the research area; the sustainability results of the farming systems reflect the reality on the ground; the nutrient flux evaluated at the crop and farm levels constitute a valuable database for future research.
