Alaska shoreline change tool

Coastlines are dynamic features that change shape and position on a range of timescales. As a result of this variability, many coastal communities in Alaska must carefully consider patterns of coastal erosion and/or accretion to appropriately plan for the future. Until now, a lack of available information and resources related to shoreline positional data has created challenges in assessing and planning for coastal hazards such as erosion. To address this identified data need, the Alaska Division of Geological & Geophysical Surveys (DGGS) has created the Alaska Shoreline Change Tool, an interactive map that displays historical and projected shoreline positions. This new tool will improve hazard assessments and aid in local management decisions. The Alaska Shoreline Change Tool contains the best available information for shoreline change analysis in Alaska. These data come from many sources and include contributions from shoreline mapping projects conducted by numerous investigators. This digital data distribution package provides digitized, historic shorelines that are proximal to the community of Emmonak.
