Description:
Abstract:
The Digital Shoreline Analysis System (DSAS) is a freely available software application that works within the Environmental Systems Research Institute (ESRI) Geographic Information System (ArcGIS) software. DSAS computes rate-of-change statistics for a time series of shoreline vector data. Additionally, the DSAS application is useful for computing rates of change for any boundary-change problem that incorporates a clearly-identified feature position at discrete times, such as glacier limits, river banks, or land use/cover boundaries.
The "bias feature" is a shapefile representation the proxy-datum bias (PDB) data previously published in tabular format (Himmelstoss and others 2010, Himmelstoss and others 2018). These PDB data are used to shift older proxy-based shorelines so that they can be directly compared to newer datum-based shorelines and accurate rates can be calculated.
Purpose:
This feature records the proxy-datum bias (PDB) and the uncertainty in the PDB. These data are provided for users of the ArcGIS DSAS extension and should only be used to determine the corrected change rate when both datum based (e.g. MHW) and proxy-based (e.g. HWL) shorelines occur. These data should not be used for any purpose other than that for which they are intended. The United States Geological Survey does not guarantee its validity. Assumptions, analyses, opinions, and actual outcomes may vary. The user should always verify actual data and exercise their own professional judgment when interpreting any outcomes.
Supplemental_Information:
Cross-referenced citations are applicable to the dataset as a whole. Additional citations are located within individual process steps that pertain specifically to the method described in that step.

Process_Description:
The profile method of shoreline extraction (Stockdon and others 2002), extracts an elevation based shoreline from point cloud lidar data using a Matlab-based approach (Matlab version 2015b). Using a coast-following reference line with 20 m spaced profiles, lidar data is analyzed within a two meter swath around each profile. This method is used to extract MHW shoreline, slope and uncertainty information. The slope data for each profile was saved. The slope at each profile was averaged over time using data from the years 2000, 2011, 2014 and 2018.

Process_Description:
There is a known horizontal offset between the datum-based lidar MHW shoreline and the proxy-based historical shorelines on open-ocean sandy beaches that nearly always acts in one direction (Ruggiero and List, 2009). This bias is called the proxy-datum bias (PDB). The PDB is primarily due to wave run-up and thus is affected by the slope of the foreshore and the movement of water (waves, tides) onto the foreshore, see equation for the PDB and the PDB uncertainty in Ruggiero and List, 2009. These equations require beach slope and wave data. Ideally data collected at the time the proxy-based shoreline was collected would be used, however, for our purposes the PDB is estimated by averaging all available slope data (from step 1) and averaging at least 10 years of historical wave data from a nearby buoy ( https://www.ndbc.noaa.gov/) and the U.S. Wave Information Study (WIS - https://www.ncei.noaa.gov/access/metadata/landing-page/bin/iso?id=gov.noaa.ncdc:C00071) The PDB is stored to a point shapefile at the intersection of the each profile with the coast-following reference line.

NOTE: Many of the sheltered areas within the Massachusetts study area do not have nearby buoy data and a proxy-datum bias value cannot be calculated in these areas. Therefore, when this new datum-based MHW shoreline is compared to historic proxy-based HWL shorelines in these sheltered areas, there may be some artificial landward offset of the historic data that has not been quantified and could potentially influence the rates. However, because the PDB is primarily an estimate of wave run-up, and since sheltered areas have lower run-up, smaller values for the PDB are expected in sheltered areas. In addition, the equation for the PDB uses a wave run-up equation that has only been verified on sandy coasts. For that reason we do not apply the PDB to rocky headlands. Preliminary analysis suggests that the PDB is small on rocky headlands, however more work needs to be done to determine the correct value for PDB on rocky headlands and other non-sandy beaches.
