    "descript": "The U.S. Geological Survey (USGS) supports multiple efforts to understand and predict storm impacts to our nation's coastlines. The geospatial dataset (vector feature class) and comma-delimited American Standard Code for Information Interchange (ASCII) table describes a time series of modern foredune crest elevations and cross-shore positions across the North Carolina ocean-fronted coastline between September 1997 and October 2018. Beach width and slope statistics are additionally reported. Results are provided at an alongshore resolution of 500 meters (m) as a series of coincident points, with individual points describing dune and beach statistics derived from a particular topographic survey. Individual time series feature positions (points) represent the center of an alongshore \u201cbin\u201d and describe coastal topography statistics within 250 m alongshore on either side of the point. This data is intended as a companion to the dune condition codes provided in this same data release and are ideal for visualizing interannual changes in the dune crest and beach at individual locations. An ArcGIS Pro Map Package file is also included, which displays dune condition code and time series features with specific symbology and graphing schema that aid the user in interpreting and visualizing some of the most important attributes in the data. The methods used to generate this data followed the process outlined in \u201cDecadal-scale characteristics of natural and anthropogenic dune morphology along North Carolina barrier islands (SE Atlantic coast)\u201d by Seymour and others (2026).",
