		A Geospatial framework for the coastal zone : national needs for coastal mapping and charting / par Charting,, Committee on National Needs for Coastal Mapping and. Publication : [S.l.] : National Academies Press, 2004 . 168 p. ; , The coastal zone is of enormous importance to the well-being of the nation, as our lives and economy are inextricably linked to the features and activities that occur within this dynamic region. In order to understand and address the effects of natural and anthropogenic forces in the coastal zone, a holistic multidisciplinary framework is required to account for the interconnectivity of processes within the system. The foundation of this framework is accurate geospatial information - information that is depicted on maps and charts. "A Geospatial Framework for the Coastal Zone: National Needs" identifies and suggests mechanisms for addressing national needs for spatial information in the coastal zone. It identifies high priority needs, evaluates the potential for meeting those needs based on the current level of effort, and suggests steps to increase collaboration and ensure that the nation's need for spatial information in the coastal zone is met in an efficient and timely manner. 23 cm.

		Contaminants in the subsurface : source zone assessment and remediation / par Subsurface,, Committee on Source Removal of Contaminants in the. Publication : [S.l.] : National Academies Press, 2005 . 372 p. ; , At hundreds of thousands of commercial, industrial, and military sites across the country, subsurface materials including groundwater are contaminated with chemical waste. The last decade has seen growing interest in using aggressive source remediation technologies to remove contaminants from the subsurface, but there is limited understanding of: the effectiveness of these technologies; and the overall effect of mass removal on groundwater quality. This report reviews the suite of technologies available for source remediation and their ability to reach a variety of cleanup goals, from meeting regulatory standards for groundwater to reducing costs. The report proposes elements of a protocol for accomplishing source remediation that should enable project managers to decide whether and how to pursue source remediation at their sites. 23 cm.

		Direct and indirect human contributions to terrestrial carbon fluxes : a workshop summary / par Johnson,, Rob Coppock and Stephanie. Publication : [S.l.] : National Academies Press, 2004 . 92 p. ; , Human-induced climate change is an important environmental issue worldwide, as scientific studies increasingly demonstrate that human activities are changing the Earth's climate. Even if dramatic reductions in emissions were made today, some human-induced changes are likely to persist beyond the 21st century. The Kyoto Protocol calls for emissions reporting that separates out management-induced changes in greenhouse gases from those changes caused by indirect human effects (e.g., carbon dioxide fertilization, nitrogen deposition, or precipitation changes), natural effects, and past practices on forested agricultural lands. This book summarizes a September 2003 workshop where leaders from academia, government and industry came together to discuss the current state of scientific understanding on quantifying direct human-induced change in terrestrial carbon stocks and related changes in greenhouse gas emissions and distinguishing these changes from those caused by indirect and natural effects. 23 cm.

		Groundwater fluxes across interfaces / par Science,, Committee on Hydrologic. Publication : [S.l.] : National Academies Press, 2004 . 100 p. ; , Estimates of groundwater recharge and discharge rates are needed at many different scales for many different purposes. These include such tasks as evaluating landslide risks, managing groundwater resources, locating nuclear waste repositories, and estimating global budgets of water and greenhouse gasses. "Groundwater Fluxes Across Interfaces" focuses on scientific challenges in: the spatial and temporal variability of recharge and discharge; how information at one scale can be used at another; and the effects of groundwater on climate and vice versa. 28 cm.

		Improving the scientific foundation for atmosphere-land-ocean simulations : report of a workshop / par Models,, Committee on Challenges in Representing Physical Processes in Coupled Atmosphere-Land-Ocean. Publication : [S.l.] : National Academies Press, 2005 . 84 p. ; , The National Academies' Board on Atmospheric Sciences and Climate (BASC) held a workshop to explore and evaluate current efforts to model physical processes of coupled atmosphere-land-ocean (A-L-O) models. Numerical models of the atmosphere and ocean are central to weather prediction, research, and education. Although great strides have been made over the past few decades in understanding the atmosphere and ocean, modeling capabilities, and numerical A-L-O simulations, some unresolved processes in the models do not adequately represent knowledge of the underlying physics. Moreover, there is evidence that further progress in numerical simulations is being impeded by the slow pace of improvement in the representation of key physical processes in the models and the fact that geophysical flow models are not receiving the attention needed to make these tools more useful and accurate. These models often are used to predict future events, so it is imperative that their underlying physical processes be represented as robustly as possible. During the workshop, the parameterization of physical processes in A-L-O models was addressed, including associated errors, testing, and efforts to improve the use of parameterizations. Participants also examined intellectual and scientific challenges in modeling and highlighted the idea that some of the key impediments to progress in representing physical processes are primarily cultural in nature. 23 cm.

		Living on an active earth : perspectives on earthquake science / par Earthquakes,, Committee on the Science of. Publication : [S.l.] : National Academies Press, 2003 . 432 p. ; , The destructive force of earthquakes has stimulated human inquiry since ancient times, yet the scientific study of earthquakes is a surprisingly recent endeavor. Instrumental recordings of earthquakes were not made until the second half of the 19th century, and the primary mechanism for generating seismic waves was not identified until the beginning of the 20th century. From this recent start, a range of laboratory, field, and theoretical investigations have developed into a vigorous new discipline: the science of earthquakes. As a basic science, it provides a comprehensive understanding of earthquake behavior and related phenomena in the Earth and other terrestrial planets. As an applied science, it provides a knowledge base of great practical value for a global society whose infrastructure is built on the Earth's active crust. This book describes the growth and origins of earthquake science and identifies research and data collection efforts that will strengthen the scientific and social contributions of this exciting new discipline. 24 cm.

		Re-engineering water storage in the everglades : risks and opportunities / par Ecosystem,, Committee on Restoration of the Greater Everglades. Publication : [S.l.] : National Academies Press, 2005 . 140 p. ; , The Water Science and Technology Board and the Board on Environmental Studies and Toxicology have released the seventh and final report of the Committee on Restoration of the Greater Everglades Ecosystem, which provides consensus advice to the South Florida Ecosystem Restoration Task Force on various scientific and technical topics. Human settlements and flood-control structures have significantly reduced the Everglades, which once encompassed over three million acres of slow-moving water enriched by a diverse biota. To remedy the degradation of the Everglades, a comprehensive Everglades Restoration Plan was formulated in 1999 with the goal of restoring the original hydrologic conditions of its remaining natural ecosystem. A major feature of this plan is providing enough storage capacity to meet human needs while also providing the needs of the greater Everglades ecosystem.This report reviews and evaluates not only storage options included in the Restoration Plan but also other options not considered in the Plan. Along with providing hydrologic and ecological analyses of the size, location and functioning of water storage components, the report also discusses and makes recommendations on related critical factors, such as timing of land acquisition, intermediate states of restoration, and tradeoffs among competing goals and ecosystem objectives. 28 cm.

		The geological record of ecological dynamics : understanding the biotic effects of future environmental change / par Dynamics,, Committee on the Geologic Record of Biosphere. Publication : [S.l.] : National Academies Press, 2005 . 216 p. ; , In order to answer important questions about ecosystems and biodiversity, scientists can look to the past geological record which includes fossils, sediment and ice cores, and tree rings. Because of recent advances in earth scientists' ability to analyze biological and environmental information from geological data, the National Science Foundation and the U.S. Geological Survey asked a National Research Council (NRC) committee to assess the scientific opportunities provided by the geologic record and recommend how scientists can take advantage of these opportunities for the nation's benefit. The committee identified three initiatives for future research to be developed over the next decade: use the geological record as a 'natural laboratory' to explore changes in living things under a range of past conditions; use the record to better predict the response of biological systems to climate change; and, use geologic information to evaluate the effects of human and non-human factors on ecosystems. The committee also offered suggestions for improving the field through better training, improved databases, and additional funding. 23 cm.

		Thinking strategically : the appropriate use of metrics for the climate change science program / par Research,, Committee on Metrics for Global Change. Publication : [S.l.] : National Academies Press, 2005 . 162 p. ; , The Climate Change Science Program (CCSP) and its predecessor U.S. Global Change Research Program have sponsored climate research and observations for nearly 15 years, yet, the overall progress of the program has not been measured systematically. Metrics - a system of measurement that includes the item being measured, the unit of measurement, and the value of the unit - offers a tool for measuring such progress; improving program performance; and demonstrating program successes to Congress, the Office of Management and Budget, and the public. This report lays out a framework for creating and implementing metrics for the CCSP. A general set of metrics provides a starting point for identifying the most important measures, and the principles provide guidance for refining the metrics and avoiding unintended consequences. 23 cm.
