Tripping from the Fall Line


Book Description

"Emanating from the Fall Line city of Baltimore, site of the 2015 GSA Annual Meeting, these trips reflect the diversity of geological features in the mid-Atlantic region including the Piedmont, Appalachian Mountains, and Coastal Plain, and the importance of geology on the development and construction of the Baltimore-Washington, D.C., metropolitan area"--

Sample Return Missions


Book Description

Sample Return Missions: The Last Frontier of Solar System Exploration examines the discoveries and results obtained from sample return missions of the past, present, and future. It analyses the results in the context of the current state of knowledge and their relation to the formation and evolution of planetary bodies, as well as to the available technologies and techniques. It provides detailed descriptions of experimental procedures applied to returned samples. Beginning with an overview of previous missions, Sample Return Missions then goes on to provide an overview of facilities throughout the world used to analyze the returned samples. Finally, it addresses techniques for collection, transport, and analysis of the samples, with an additional focus on lessons learned and future perspectives. Providing an in-depth examination of a variety of missions, with both scientific and engineering implications, this book is an important resource for the planetary science community, as well as the experimentalist and engineering communities. Presents sample return results obtained so far in relation to remote sensing measurements, methods and techniques for laboratory analysis, and technology Provides an overview of a variety of sample return missions, from Apollo, to Hayabusa-2, to future missions Examines technological and methodological advances in analyzing returned samples, as well as the resources available globally




Shoreline Protection and Beach Erosion Control Study: An Analysis of the U.S. Army Corps of Engineers Shore Protection Program


Book Description

This report presents the results of a study performed by the Army Corps of Engineers in response to a request by the Office of Management and Budget for the Army to analyze the effectiveness of the Federal shore protection program. This report defines the scope of the shore protection program over the period 1950-1993 in terms of the number and types of protective measures, lineal distances of protected shorelines, actual costs and costs updated to 1993, quantities of sand used in restoration and nourishment, and benefits. The report compares estimated against actual costs, quantities of sand and benefits; provides an analysis of Federal programs that are involved in risk management in the coastal zone; the environmental effects of shore protection projects; a discussion of the level of protection afforded by beach projects; and the question of whether or not shore protection projects induce development. Future costs of constructed protects as well as an estimate of projected costs for projects which have a possibility of being constructed in the next fifteen years.










Coastal Fluxes in the Anthropocene


Book Description

This book synthesizes knowledge of coastal and riverine material fluxes, biogeochemical processes and indications of change, both natural, and increasingly human-initiated. Here, the authors assess coastal flux in the past and present, and in future under the International Geosphere-Biosphere Programme (IGBP), the International Human Dimensions Programme on Global Environmental Change (IHDP) and the LOICZ II (Land-Ocean Interactions in the Coastal Zone) Project.
