Alaska Coastal Profile Tool (ACPT)

Description

Alaska Coastal Profile Tool (ACPT), Digital Data Series 7 v.2, provides shoreface elevation measurements collected by various stakeholders since the 1960s; many of which are unpublished or inaccessible. Since May 30, 1975, Alaska Division of Geological & Geophysical Surveys (DGGS) staff and others have compiled statewide elevation profiles to preserve historical coastal data, establish a centralized repository for future datasets, and support consistent, accurate, and repeatable observations along existing profiles. These shore-normal measurements are especially valuable when sites are revisited seasonally or interannually, helping to document change and assess vulnerability in Alaska's dynamic coastal environments. The database accommodates diverse data collection methods, including differential leveling, survey-grade global positioning system (GPS), and digital elevation model extraction. It incorporates contributions from community-led efforts and state, federal, and academic partners. For this version 2 release, DGGS integrated previously stored data with post-update acquisitions and reprocessed the data to improve the reliability of comparative analyses and the precision of future datasets. The database will be updated as new data become available, ensuring that derived products evolve. Its open-access design encourages broad participation in community-based coastal monitoring and fosters a deeper understanding of shoreline change across the state. All files can be downloaded from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/31747).
