The deep oceans are the last great frontier remaining on Earth. Humans have conquered the vast wilderness of the terrestrial surface, from the searing deserts and dark forests of the tropics to the icy polar regions. Today, anyone with enough ambition and money can travel upriver into the heart of the Borneo jungle, climb Mount Everest, or spend the night at the South Pole. But the oceans beyond the continental shelves remain forbidding, beyond the reach of science, adventurism, and commerce.

Not long ago, scientists viewed the ocean floor as a vast, featureless plain, an ancient repository of detritus eroded from the surface of an unchanging Earth. Light never reached the seemingly lifeless depths. The ocean basins were only of marginal scholarly interest. This all changed with the Herculean quest to discover what lay on the world's ocean floor -- a quest that inspired the continental drift-plate tectonics revolution and overturned prevailing scientific notions of how the Earth's surface was created, rearranged, and destroyed.

Upheaval from the Abyss spans a 130-year period, beginning with the early, backbreaking efforts to map the depths during the age of sail; continuing with improvements in research methods spurred by maritime disaster and war; and culminating in the publication of the first map of the world's ocean floor in 1977. David M. Lawrence brings this tale to life by weaving through it the personalities of the scientists-explorers who struggled to see the face of the deep, and reveals not only the facts of how the ocean floor was mapped, but also the human dimensions of what the scientists experienced and felt while in the process.

Public health refers to the management and prevention of disease within a population by promoting healthy behaviors and environments in an effort to create a higher standard of living. In this comprehensive volume, editor James W. Holsinger Jr. and an esteemed group of scholars and practitioners offer a concise overview of this burgeoning field, emphasizing that the need for effective services has never been greater. Designed as a supplemental text for introductory courses in public health practice at the undergraduate and graduate levels, Contemporary Public Health provides historical background that contextualizes the current state of the field and explores the major issues practitioners face today. It addresses essential topics such as the social and ecological determinants of health and their impact on practice, marginalized populations, the role of community-oriented primary care, the importance of services and systems research, accreditation, and the organizational landscape of the American public health system. Finally, it examines international public health and explores the potential of systems based on multilevel partnerships of government, academic, and nonprofit organizations. With fresh historical and methodological analyses conducted by an impressive group of distinguished authors, this text is an essential resource for practitioners, health advocates, and students.
