Coastal Change Analyses for Western Alaska: Interactive Map

Covering the entire extent of the Western Alaska Landscape Conservation Cooperative’s area, this analyses provide important baseline information on the distribution and magnitude of landscape changes from erosion and aggradation (deposition) over 41 years. The maps document changes in the shape and extent of land, as well as in coastal features such as spits, barrier islands, estuaries, tidal guts, and lagoons. Western Alaska Native coastal communities may use this mapping tool to summarize changes for various parcels of land or assess the extent of habitat loss or gain over the study period.
