In accordance with SO #3423 - The Gulf of America and SO #3424 - Mount McKinley and Landmarks Honoring the Alaskan People, new USGS data releases specific to those named places will utilize the new name Gulf of America and the restored name Mount McKinley. Per USGS practice, historical data will retain the name of the geographic features as they were known at the time the data were originally released.

Shoreline Change Analysis of Coastal and Estuarine Shorelines in Barnegat and Great Bays, NJ: 1839 to 2012
By Kathryn E.L. Smith and Joseph F. Terrano
USGS, St. Petersburg, Florida
Summary
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. For additional information on AMBUR, see Jackson, C.W., Jr., 2010, Basic User Guide for the AMBUR package for R, version 1.0a.
