Shoreline position changes between about 1850 and 1980 along the ocean coastal reach from 12 km west of Cape Henry, Virginia, to 8 km west of Cape Hatteras, North Carolina, are documented in this report. In places where the ocean shoreline is on an island or spit, shoreline changes in the sound or bay are also given. Shoreline movement maps at a scale of 124,000 constitute the basic data set included in the report. Composite reproductions of these maps are shrinkwrapped separately. In addition, ocean and sound shoreline changes averaged for 1-minute-latitude- or longitude- distance increments are provided. Consistent alongshore trends in the shoreline change rate are evident only from Virginia Beach south to the Virginia-North Carolina border and for about 15 km north of Cape Hatteras. Other areas experienced variable rates of shoreline change. The highest average shoreline change rate, about -2.0 myear, occurred between 1917 and 1949. From about 1850 to 1917, the shoreline change rate averaged -0.1 myear, and for the past 30 years it has averaged about -0.8 myear. Author
