Shoreline Change Analysis of Coastal and Estuarine Shorelines in Barnegat and Great Bays, NJ: 1839 to 2012

Shoreline erosion is a significant issue for many coastal states, and as coastal populations continue to grow, these data will become increasingly important for managing coastal habitats and communities. The data presented here include compiled vectorized shorelines and transects with shoreline change rates for both estuarine and open-ocean shorelines in Barnegat and Great Bays, New Jersey. Shoreline change was calculated from digital vector shorelines acquired from historical topographic sheets, aerial photography, and/or lidar. Shoreline change rates are estimated from the shoreline position of multiple dated datasets utilizing the intersection with a perpendicular transect to the congregate shoreline. These analyses were conducted using the Analyzing Movement Boundaries Using R (AMBUR) package.
