Alaska: East Chukchi Sea Coast (Point Barrow to Icy Cape) transects with short-term (ST) end point rate calculations for the exposed coast

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: May 05, 2026 at 08:05 PM | Dataset Last Updated: March 26, 2026 at 12:00 AM
This dataset consists of short-term (~32 years) shoreline change rates for the north coast of Alaska between Point Barrow and Icy Cape. Rate calculations were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 4.3, an ArcGIS extension developed by the U.S. Geological Survey. Short-term rates of shoreline change were calculated using an end point rate-of-change method based on available shoreline data between 1979 and 2011. A reference baseline was used as the originating point for the orthogonal transects cast by the DSAS software. The transects intersect each shoreline establishing measurement points, which are then used to calculate short-term rates.
