    Metadata Updated: January 16, 2026

    This dataset represents the shoreline positions that were surveyed at the beginning and end of a one year study of erosion along the back barrier (western shoreline) of Cumberland Island National Seashore (CUIS). Additionally, this dataset also contains projected shoreline positions for the year 2050 and 2100 derived from erosion rates observed in this study and the R package - Analysis of Moving Boundaries Using R (AMBUR). To determine shoreline positions, points were surveyed along the edge of the margin scarp using either a Trimble R8 Real-Time Kinematic Global Positioning System (RTK GPS) unit, a Trimble S6 total station, or both. Points were then converted to a polyline feature to represent the position and configuration of the selected sites shoreline. The goal of this exercise was to estimate the net amount of retreat which could be compared to other methods that were being used in this study.
