Summary
The U.S. Geological Survey (USGS) is conducting a national assessment of coastal change hazards. One component of this research effort, the National Assessment of Shoreline Change Project (http://coastal.er.usgs.gov/shoreline-change/), documents changes in shoreline position as a proxy for coastal change. Data for calculating historical rates of shoreline change for the Central Beaufort Sea coast of Alaska are included here. Data for all the USGS National Assesment of Shoreline Change Projects can be viewed on the USGS Coastal Change Hazards Portal at https://marine.usgs.gov/coastalchangehazardsportal/.

Purpose
This data release is an update to the North coast of Alaska long-term shoreline change assessment data (Gibbs and others, 2015; https://pubs.usgs.gov/of/2015/1030/). It includes revised rate-of-change calculations based on additional shoreline position data and improved rate metrics.
