"Imagine yourself exploring the most extreme parts of our amazing oceans-riding the tallest waves, diving to the darkest depths, and encountering the largest and most dangerous sea creatures on Earth. Join award-winning author Seymour Simon as he introduces you to the most extreme environments, animals, plants, and weather in the ocean! These mind-bending facts and stunning photographs invite you on an exciting, and sometimes unbelievable, underwater expedition"--Provided by publisher.

There are over 100 billion gallons of water for each person on earth, nearly all of it churning in waves and currents driven by the sun's energy. Our ocean world is enormous, and its power affects our climate and reshapes the land. From the moon's mysterious power over the tides to deadly waves called tsunami, explore Earth's oceans in this book awash with photographs and fascinating facts.

The oceanographer Tessa Hill and the science journalist Eric Simons profile efforts to understand and protect marine environments, taking readers to habitats from shallow tidepools to the deep sea.

Effective coastal engineering is expensive, but it is not as costly as neglect or ineffective intervention. Good practice needs to be based on sound principles, but theoretical work and modelling also need to be well grounded in practice, which is continuously evolving. Conceptual and detailed design has been advanced by new industry publications since the publication of the second edition. This third edition provides a number of updates: the sections on wave overtopping have been updated to reflect changes brought in with the recently issued EurOtop II manual; a detailed worked example is given of the calculation of extreme wave conditions for design; additional examples have been included on the reliability of structures and probabilistic design; the method for tidal analysis and calculation of amplitudes and phases of harmonic constituents from water level time series has been introduced in a new appendix together with a worked example of harmonic analysis; and a real-life example is included of a design adapting to climate change. This book is especially useful as an information source for undergraduates and engineering MSc students specializing in coastal engineering and management. Readers require a good grounding in basic fluid mechanics or engineering hydraulics, and some familiarity with elementary statistical concepts.

Through direct exploration of the subseafloor, U.S.-supported scientific ocean drilling programs have significantly contributed to a broad range of scientific accomplishments in Earth science disciplines, shaping understanding of Earth systems and enabling new fields of inquiry. Scientific Ocean Drilling: Accomplishments and Challenges reviews the scientific accomplishments of U.S.-supported scientific ocean drilling over the past four decades. The book evaluates how the programs (Deep Sea Drilling Project [DSDP], 1968-1983, Ocean Drilling Program [ODP], 1984-2003, and Integrated Ocean Drilling Program [IODP], 2003-2013) have shaped understanding of Earth systems and Earth history and assessed the role of scientific ocean drilling in enabling new fields of inquiry. This book also assesses the potential for transformative discoveries for the next proposed phase of scientific ocean drilling, which is scheduled to run from 2013 to 2023. The programs' technological innovations have played a strong role in these accomplishments. The science plan for the proposed 2013-2023 program presents a strong case for the continuation of scientific ocean drilling. Each of the plan's four themes identifies compelling challenges with potential for transformative science that could only be addressed through scientific ocean drilling, although some challenges appear to have greater potential than others. Prioritizing science plan challenges and integrating multiple objectives into single expeditions would help use resources more effectively, while encouraging technological innovations would continue to increase the potential for groundbreaking science.

"In the quarter century that followed American entry into World War II, the nation's armed forces moved from the reluctant inclusion of a few segregated Negroes to their routine acceptance in a racially integrated military establishment. Nor was this change confined to military installations. By the time it was over, the armed forces had redefined their traditional obligation for the welfare of their members to include a promise of equal treatment for black servicemen wherever they might be. In the name of equality of treatment and opportunity, the Department of Defense began to challenge racial injustices deeply rooted in American society. For all its sweeping implications, equality in the armed forces obviously had its pragmatic aspects. In one sense it was a practical answer to pressing political problems that had plagued several national administrations. In another, it was the services' expression of those liberalizing tendencies that were permeating American society during the era of civil rights activism. But to a considerable extent the policy of racial equality that evolved in this quarter century was also a response to the need for military efficiency. So easy did it become to demonstrate the connection between inefficiency and discrimination that, even when other reasons existed, military efficiency was the one most often evoked by defense officials to justify a change in racial policy."_x000D_ Morris J.
