Description:
Abstract:
This dataset includes historical shoreline positions that span 70 years, from 1947 to 2017, for the north coast of Alaska between the Hulahula River and the Colville River. Shorelines were compiled from topographic survey sheets (T-sheets; National Oceanic and Atmospheric Administration (NOAA)), aerial orthophotographs (U.S. Geological Survey (USGS), National Aeronautics and Space Administration (NASA), Conoco-Philips (CP), British Petroleum Alaska (BPXA), and NOAA), satellite imagery (U.S. Fish and Wildlife Service (USFWS) and State of Alaska), and lidar elevation data (USGS). Historical shoreline positions serve as easily understood features that can be used to describe the movement of beaches through time. These data are used to calculate rates of shoreline change. Rates of long-term (70 years) and short-term (less than 40 years) shoreline change were generated in a GIS using the Digital Shoreline Analysis System (DSAS) version 5.1. DSAS uses a measurement baseline method to calculate rate-of-change statistics. Transects are cast from the reference baseline to intersect each shoreline, establishing measurement points used to calculate shoreline change rates.
Purpose:
Coastal erosion is a persistent process along most open-ocean shores of the United States and affects both developed and natural coastlines. Along the Arctic coast of Alaska, coastal erosion is widespread and threatens communities, defense and energy-related infrastructure, and coastal habitat. As the coast changes, there are a wide range of ways that change can affect coastal communities, habitats, and the physical characteristics of the coast-including beach erosion, shoreline retreat, land loss, and damage to infrastructure. The U.S. Geological Survey (USGS) is responsible for conducting research on coastal change hazards, understanding the processes that cause coastal change, and developing models to forecast future change. To understand and adapt to shoreline change, accurate information regarding the past and present configurations of the shoreline is essential and a comprehensive, nationally consistent analysis of shoreline movement is needed. To meet this national need, the USGS is conducting an analysis of historical shoreline changes along open-ocean coasts of the United States and parts of the Great Lakes. In Alaska, coastlines sheltered from open-ocean wave conditions by barrier islands are also included in the analysis because of their importance to defense and energy-related infrastructure and to understand the similarities, differences, and linkages in coastal behavior and physical processes acting on exposed and sheltered permafrost coastlines. This dataset is one in a series of regionally focused reports on historical shoreline change. As more data are gathered, periodic updates are made, which provide information that can be used in multidisciplinary assessments of global change impacts.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The data provided here are a compilation of shorelines from multiple sources, spanning 70 years. The attributes in this table record positional and measurement uncertainties and datum offsets calculated during the process of extracting the land/water interface shoreline from the orthoimagery data as described in the process steps. The attributes are based on the requirements of the Digital Shoreline Analysis System (DSAS) software and have gone through a series of quality assurance procedures.
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 taken into account in the uncertainty of the shoreline position, as reported in this metadata file. For more information see Gibbs and Richmond (2017).
Completeness_Report:
This shoreline file is complete and contains all shoreline segments used to calculate shoreline change rates 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 non-existing data or existing data that did not meet quality assurance standards.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal accuracy of the shoreline data varies with respect to the data source from which the shorelines were digitized, the lidar data from which the shorelines were extracted, and the time period. Shorelines digitized from the 1940s and 1980s era T-sheets have an estimated total shoreline position uncertainty of plus or minus 16 meters. Shorelines digitized from the 1980s era Alaska High Altitude Photography (AHAP) have an estimated shoreline position uncertainty of plus or minus 10 meters. Shorelines digitized from 1997-2007 orthophotographs have an estimated total shoreline position uncertainty of plus or minus 3 to 6 meters. Shorelines digitized from 2003 QuickBird imagery have an estimated total shoreline position uncertainty of plus or minus 6 meters. Shorelines digitized from 2009-2012 lidar data have an estimated total shoreline position uncertainty of plus or minus 3 to 10 meters. Shorelines digitized from the 2017 NOAA orthophotography have an estimated positional uncertainty of plus or minus 3 to 10 meters. Please visit the 'Estimation of Shoreline Position Uncertainty' section in Gibbs and Richmond (2017) for a complete explanation of the measurement uncertainties associated with these shorelines.

Process_Step:
Process_Description:
Data from the previously-published National Assessment of Shoreline Change: Summary Statistics for Updated Vector Shorelines and Associated Shoreline Change Data for the North Coast of Alaska, U.S.--Canadian Border to Icy Cape (USGS Open-File Report 2017-1107) and associated data release (https://doi.org/10.5066/F72Z13N1)were used as the starting point for this update. New shoreline positions were digitized from the 2017 NOAA imagery.
Process_Date: 2023
Process_Step:
Process_Description:
T-sheets were geo-registered using Esri ArcMap software (v9.3) by placing 8-20 well-spaced ground control points (GCP) at gridline intersections and applying a third-order polynomial transformation. Some T-sheets may have required additional coordinate transformation information from NOAA to account for datum offsets between historical datums (USSD) and modern datums (NAD27 or NAD83). Datum transformations were applied to GCP coordinates prior to registration. Total root-mean-square error (RMSE) for the rectification process was maintained below 0.0001 degrees, which is approximately 11 m at this latitude. Typically the resulting RMSE was much lower than 0.0001 degree.
