Book Description
Covering 71 percent of the planet, these saline bodies of water provided the unique conditions necessary for the building blocks of life to form billions of years ago. This book explains how our oceans continue to support and influence life in important ways: by providing the largest global source of protein in the form of fish populations, by creating and influencing weather systems, and by absorbing waste streams such as airborne carbon. It is shown how oceans have an almost magnetic draw—almost half of the world’s population lives within a few hours of an ocean. Although oceans are vast in size, exceeding 328 million cubic miles (1.37 billion cubic kilometers), they have been influenced by and have influenced humans in numerous ways. The book includes three detailed case studies. The first focuses on the most remote locations along the Mid-Atlantic Ridge, where new ocean floor is being formed twenty-thousand feet underwater. The second considers the Maldives, a string of islands in the Indian Ocean, where increasing sea levels may force residents to abandon some communities by 2020. The third describes the North Sea at the edge of the Arctic Ocean, where fishing stocks have been dangerously depleted as a result of multiple nations’ unrelenting removal of the smallest and largest species.

Book Description
Earth's seas play a tremendous role in the planet's systems: Ocean currents transfer water and heat around the globe. Offering photographs and illustrations, this work shows how protecting the oceans requires protecting the entire planet, and describes the importance of setting aside marine reserves to save vital ecosystems.

Book Description
The earth is continuously changing and evolving yet it is unclear how environmental changes will affect us in years to come. What changes are inevitable? What changes, if any, are beneficial? And what can we do as citizens of this planet to protect it and our future generations? Larry Slobodkin, one of the leading pioneers of modern ecology, offers compelling answers to these questions in A Citizen's Guide to Ecology. He provides many insights into ecology and the processes that keep the world functioning. This important guide introduces observations that underlie arguments about all aspects of the natural environment--including both global and local issues. To clarify difficult concepts, Slobodkin uses lake, ocean, and terrestrial ecosystems to explain ecological energy flows and relationships on a global scale. The book presents a clear and current understanding of the ecological world, and how individual citizens can participate in practical decisions on ecological issues. It tackles such issues as global warming, ecology and health, organic farming, species extinction and adaptation, and endangered species. An excellent introduction and overview, A Citizen's Guide to Ecology helps us to understand what steps we as humans can take to keep our planet habitable for generations to come. "This beautifully written book brings together careful observation, personal reflection, and theoretical understanding to explain the major environmental problems that confront us. Dr. Slobodkin's superb and sweeping work invites us to contemplate a great many facts and a few large values to motivate a clear and compelling response to losses of biodiversity, the problem of invasive species, global warming, and other environmental concerns."--Mark Sagoff, School of Public Affairs, University of Maryland

Book Description
For the past several years, a number of research programs have funded significant efforts to advance understanding of and forecasting capabilities for the Gulf of Mexico circulation, including the Loop Current, its associated eddies, and abyssal dynamics. One such program is the National Academies’ Understanding Gulf Ocean Systems initiative, which focuses on improving forecasts of the physical dynamics of the open Gulf of Mexico in space and time scales useful for the reduction of risks to offshore energy exploration and production, as well as for other challenges such as forecasting hurricane intensification and managing fisheries. What has been learned, how can this scientific progress be incorporated into operational models, and what are the remaining gaps in knowledge impeding predictive skill?

Book Description
The oceans are teeming with life of all kinds. Changing sea levels, plate tectonics, chemical cycling, sedimentation, and the atmosphere greatly impact these habitats. The ocean's currents and sea level are tied closely to weather patterns and in turn to such issues as global warming and El Nino. Oceans provides a complete overview of the ecosystem that exists in these bodies of water. From the coastal wetlands to the deep ocean waters, the geography, geology, chemistry, and physics of oceans are thoroughly examined in this volume. Today, the impact that human use of ocean resources has on these habitats, including habitat loss and overharvesting, is in constant debate. Oceans looks at these possible threats and concludes with a balanced look at the ways to manage the oceans, as well as the future of this ecosystem.
