National Assessment of Shoreline Change: Historical Shoreline Change Along the New England and Mid-Atlantic Coasts

摘要

This report on the New England and Mid-Atlantic coasts is the fifth in a series of reports on historical shoreline change. Previous investigations include analyses and descriptive reports of the Gulf of Mexico (Morton and others, 2004), the Southeast Atlantic (Morton and Miller, 2005), and, for California, the sandy shoreline (Hapke and others, 2006) and the coastal cliffs (Hapke and Reid, 2007). This report, like the earlier reports, summarizes the methods of analysis, interprets the results, provides explanations regarding long-term and short-term trends and rates of change, and describes how different coastal communities are responding to coastal erosion. This report differs from the earlier USGS reports in the series in that the previous shoreline change analyses incorporated only four total shorelines to represent specific time periods. The New England and Mid-Atlantic assessment incorporates all shorelines that are available and can be quality-checked.
