Description:
Abstract:
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 shoreline vectors, including data source and acquisition date, from five time periods: 1950s, 1980s, 2000s, 2010s, and 2020s. The shoreline vectors were combined to produce polygons upon which the metrics were calculated.
Purpose:
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.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The attributes in this dataset record positional and measurement uncertainties calculated during the process of extracting a land/water interface shoreline from the data as described in the process steps.
Logical_Consistency_Report:
Adjacent shoreline segments do not overlap and are not necessarily continuous. Shorelines were quality checked for accuracy. Any slight offsets between adjacent segments due to georeferencing and digitizing error are accounted for in the uncertainty calculations included in Gibbs and others (2015), Gibbs and others (2017), and Gibbs and others (2019).
Completeness_Report:
This shoreline file is complete and contains all shoreline segments used to calculate morphological metrics along sections of the specified Alaska coastal region where shoreline position data were available. These data adequately represented the shoreline position at the time of the survey. Remaining gaps in these data are a consequence of nonexisting data or existing data that did not meet quality assurance standards.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. The horizontal accuracy of shorelines compiled from 1947 to 2019 data varies with respect to the data source from which the shorelines were digitized and the time period. Please visit the 'Estimation of Shoreline Position Uncertainty' section in Gibbs and Richmond (2015), Gibbs and Richmond (2017) and Gibbs and others (2019) for a complete explanation of the measurement uncertainties associated with these shorelines.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
A formal accuracy assessment of the vertical positional information in the data set is not applicable.

Process_Step:
Process_Description:
Shoreline vectors for barriers and spits were from Gibbs and others (2017), Snyder and Gibbs, (2019), and NOAA CUSP (2020) and merged into a single shapefile. Spits and barrier beaches were closed at the transition point to the mainland. An Era attribute was assigned based on the time period and source of the original data. The barriers were subdivided into forty-two barrier chains based on location and continuity. Each barrier was assigned a unique Barrier_ID within each Era. Additional information about the shoreline data set can be found in Hamilton and others, 2021.
