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. The shoreline positions displayed by the Alaska Shoreline Change Tool web map are presented as a convenience and are intended to be a visualization of a first-order estimation of shoreline change throughout the state. This data set was created as a means to organize and provide public access to the digitized shoreline files. Users can access the data, as well as additional metadata, from the DGGS website: http://doi.org/10.14509/29504. The database and projected shoreline visualization tool are maintained by Staff at DGGS, and were initially developed by: Gould, A.I., Kinsman, N.E.M., and Hendricks, M.D. This shoreline dataset was funded by the Federal Emergency Management Agency's Cooperating Technical Partners Program (award EMS-2016CA-00006). planned Alaska Division of Geological & Geophysical Surveys Metadata Manager (907)451-5020 (907)451-5050 3354 College Road Fairbanks AK 99709-3707 USA dggspubs@alaska.gov 8 am to 4:30 pm, Monday through Friday, except State holidays pointOfContact asNeeded Engineering Engineering Geology Environmental theme Alaska Division of Geological & Geophysical Surveys The State of Alaska makes no expressed or implied warranties (including warranties for merchantability and fitness) with respect to the character, functions, or capabilities of the electronic data or products or their appropriateness for any user's purposes.

Far North Geospatial orthorectified aerial photographs from circa 1950's and 1980's along Alaska's western coastal region. Shorelines were then digitized in ArcGIS and used with the Digital Shoreline Analysis System (DSAS) to calculate rates of shoreline change and their associated uncertainties. 2016-01-01T00:00:00 Projected shoreline positions - In order to create projected shoreline positions, DGGS staff developed an ArcGIS tool to efficiently determine the location of a future shoreline position. This tool uses the long-term linear regression rate of shoreline change, calculated in DSAS, and projected along the same transect to determine a predicted shoreline position including the uncertainties. These points are connected between transects and smoothed. 2015-01-01T00:00:00 Database development - DGGS designed a repository to house these coastal data and developed and interactive map interface that allows users to explore the state to view both historic and projected shoreline positions. The database was designed to readily incorporate shoreline data from other organizations and create projected shorelines. All historic shoreline data is available for download. 2015-01-01T00:00:00 Source Contribution: historical shoreline compilationSource Type: paper Shoreline definition and detection - A review 2005-01-01 publication Coastal Education & Research Foundation Coconut Creek FL publisher Boak, E.H. originator Turner, I.L. originator null Journal of Coastal Research v. 21, no. 4 2005-01-01 Source Contribution: historical shoreline compilationSource Type: paper Temporal analysis of shoreline recession and accretion: 1991-01-01 publication Coastal Education & Research Foundation Coconut Creek FL publisher Dolan, Robert originator Fenster, M.S. originator Holme, S.J. originator null Journal of Coastal Research v. 7, no. 3 1991-01-01 Source Contribution: historical shoreline compilationSource Type: ArcGIS extension The digital shoreline analysis system (DSAS) version 4.0 - An ArcGIS extension for calculating shoreline change 2008-01-01 publication U.S. Geological Survey United States publisher Thieler, E.E. originator Himmelstoss, E.A. originator Zichichi, J.L. originator Ergul, Ayhan originator http://dggs.alaska.gov/pubs/id/29507 Open-File Report OF 2008-1278 2008-01-01 otherRestrictions Metadata Use Constraints: If the user has modified the data in any way they are obligated to describe the types of modifications they have performed in the supporting metadata file.
