Because the U.S. population continues to shift toward the coast where valuable coastal property is vulnerable to erosion, the USCG is conducting a national assessment of coastal change. One aspect of this effort, the NASC, uses shoreline position as a proxy for coastal change because shoreline position is one of the most commonly monitored indicators of environ. change. This study: (1) develops and implements improved methods of assessing and monitoring shoreline movement; and (2) improves current understanding of the processes controlling shoreline movement. This report summarizes historical shoreline changes on the 3 most densely populated islands of the 8 main Hawaiian Islands: Kauai, Oahu, and Maui. Illus. A print on demand report.

Beach erosion is a chronic problem along open-ocean shores of the U.S. As coastal populations continue to grow and community infrastructures are threatened by erosion, there is increased demand for accurate info. regarding past and present trends and rates of shoreline movement, and a need for a comprehensive analysis of shoreline movement. This report on states bordering the Gulf of Mexico (Florida, Alabama, Mississippi, Louisiana, and Texas) summarizes the methods of analysis, interprets the results, provides explanations regarding the historical and present trends and rates of change, and describes how different coastal communities are responding to coastal erosion in 2004 (prior to Hurricanes Katrina and Rita). Illustrations.

Beach erosion is a chronic problem along many open-ocean shores of the United States. As coastal populations continue to grow and community infrastructures are threatened by erosion, there is increased demand for accurate information regarding past and present trends and rates of shoreline movement. There is also a need for a comprehensive analysis of shoreline movement that is consistent from one coastal region to another. To meet this national need, the U.S. Geological Survey (USGS) has conducted an analysis of historical shoreline changes along open-ocean sandy shores of the conterminous United States and parts of Hawaii, Alaska and the Great Lakes. This book explores the development of a standard and repeatable method for mapping and analyzing shoreline movement so that periodic, systematic, internally consistent updates regarding coastal erosion and land loss can be made nationally.

As the Gulf of Mexico recovers from the Deepwater Horizon oil spill, natural resource managers face the challenge of understanding the impacts of the spill and setting priorities for restoration work. The full value of losses resulting from the spill cannot be captured, however, without consideration of changes in ecosystem services-the benefits delivered to society through natural processes. An Ecosystem Services Approach to Assessing the Impacts of the Deepwater Horizon Oil Spill in the Gulf of Mexico discusses the benefits and challenges associated with using an ecosystem services approach to damage assessment, describing potential impacts of response technologies, exploring the role of resilience, and offering suggestions for areas of future research. This report illustrates how this approach might be applied to coastal wetlands, fisheries, marine mammals, and the deep sea-each of which provide key ecosystem services in the Gulf-and identifies substantial differences among these case studies. The report also discusses the suite of technologies used in the spill response, including burning, skimming, and chemical dispersants, and their possible long-term impacts on ecosystem services.
