Archaeological Oceanography is the definitive book on the newly emerging field of deep-sea archaeology. Marine archaeologists have been finding and excavating underwater shipwrecks since at least the early 1950s, but until recently their explorations have been restricted to depths considered shallow by oceanographic standards. This book describes the latest advances that enable researchers to probe the secrets of the deep ocean, and the vital contributions these advances offer to archaeology and fields like maritime history and anthropology. Renowned oceanographer Robert Ballard--who stunned the world with his discovery of the Titanic deep in the North Atlantic--has gathered together the pioneers of archaeological oceanography, a cross-disciplinary group of archaeologists, oceanographers, ocean engineers, and anthropologists who have undertaken ambitious expeditions into the deep sea. In this book, they discuss the history of archaeological oceanography and the evolution and use of advanced deep-submergence technology to locate and excavate ancient and modern shipwrecks and cultural and other sites deep under water. They offer examples from their own expeditions and explain the challenges future programs face in obtaining access to the resources needed to carry out this important and exciting research. The contributors are Robert D. Ballard, Ali Can, Dwight F. Coleman, Mike J. Durbin, Ryan Eustace, Brendan Foley, Cathy Giangrande, Todd S. Gregory, Rachel L. Horlings, Jonathan Howland, Kevin McBride, James B. Newman, Dennis Piechota, Oscar Pizarro, Christopher Roman, Hanumant Singh, Cheryl Ward, and Sarah Webster.

This title is a comprehensive survey of maritime archaeology as seen through the eyes of nearly fifty scholars at a time when maritime archaeology has established itself as a mature branch of archaeology.

The United States faces decisions requiring information about the oceans in vastly expanded scales of time and space and from oceanic sectors not accessible with the suite of tools now used by scientists and engineers. Advances in guidance and control, communications, sensors, and other technologies for undersea vehicles can provide an opportunity to understand the oceans' influence on the energy and chemical balance that sustains humankind and to manage and deliver resources from and beneath the sea. This book assesses the state of undersea vehicle technology and opportunities for vehicle applications in science and industry. It provides guidance about vehicle subsystem development priorities and describes how national research can be focused most effectively.

This comprehensive book contains contributions from specialists who provide a complete status update along with outstanding issues encompassing different topics related to deep-sea mining. Interest in exploration and exploitation of deep-sea minerals is seeing a revival due to diminishing grades and increasing costs of processing of terrestrial minerals as well as availability of several strategic metals in seabed mineral resources; it therefore becomes imperative to take stock of various issues related to deep-sea mining. The authors are experienced scientists and engineers from around the globe developing advanced technologies for mining and metallurgical extraction as well as performing deep sea exploration for several decades. They invite readers to learn about the resource potential of different deep-sea minerals, design considerations and development of mining systems, and the potential environmental impacts of mining in international waters.

For advanced undergraduate and beginning graduate students in atmospheric, oceanic, and climate science, Atmosphere, Ocean and Climate Dynamics is an introductory textbook on the circulations of the atmosphere and ocean and their interaction, with an emphasis on global scales. It will give students a good grasp of what the atmosphere and oceans look like on the large-scale and why they look that way. The role of the oceans in climate and paleoclimate is also discussed. The combination of observations, theory and accompanying illustrative laboratory experiments sets this text apart by making it accessible to students with no prior training in meteorology or oceanography. * Written at a mathematical level that is appealing for undergraduates and beginning graduate students * Provides a useful educational tool through a combination of observations and laboratory demonstrations which can be viewed over the web * Contains instructions on how to reproduce the simple but informative laboratory experiments * Includes copious problems (with sample answers) to help students learn the material.

This publication explores the extraordinary natural phenomenon of the Gulf Stream effect, tracing its historical discovery and exploration, outlining its causes and dynamics, and examining its profound importance for the marine ecosystems of the Atlantic Ocean.

Coral reef declines have been recorded for all major tropical ocean basins since the 1980s, averaging approximately 30-50% reductions in reef cover globally. These losses are a result of numerous problems, including habitat destruction, pollution, overfishing, disease, and climate change. Greenhouse gas emissions and the associated increases in ocean temperature and carbon dioxide (CO2) concentrations have been implicated in increased reports of coral bleaching, disease outbreaks, and ocean acidification (OA). For the hundreds of millions of people who depend on reefs for food or livelihoods, the thousands of communities that depend on reefs for wave protection, the people whose cultural practices are tied to reef resources, and the many economies that depend on reefs for fisheries or tourism, the health and maintenance of this major global ecosystem is crucial. A growing body of research on coral physiology, ecology, molecular biology, and responses to stress has revealed potential tools to increase coral resilience. Some of this knowledge is poised to provide practical interventions in the short-term, whereas other discoveries are poised to facilitate research that may later open the doors to additional interventions. A Research Review of Interventions to Increase the Persistence and Resilience of Coral Reefs reviews the state of science on genetic, ecological, and environmental interventions meant to enhance the persistence and resilience of coral reefs. The complex nature of corals and their associated microbiome lends itself to a wide range of possible approaches. This first report provides a summary of currently available information on the range of interventions present in the scientific literature and provides a basis for the forthcoming final report.
