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.

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.
