Summary
A suite of morphological metrics were derived from existing shoreline and elevation datasets for barrier islands and spits located along the north-slope coast of Alaska between Cape Beaufort and the U.S.-Canadian border. This dataset includes barrier shorelines and polygons attributed with morphological metrics from five time periods: 1950s, 1980s, 2000s, 2010s, and 2020s.

These data accompany Hamilton and others (2021), a U.S. Geological Survey Open-File Report summarizing historical morphological change to barrier islands and spits located along the north-slope coast of Alaska between Cape Beaufort and the U.S.-Canadian border. The purpose of the study is to improve upon the understanding of barrier formation, evolution, and stability in a permafrost setting. The results can be used to advance an understanding of barrier island dynamics and better predict future barrier evolution and prevalence along Alaska’s coast.
