Description:
Abstract:
This dataset represents shoreline change rates for the New Jersey coastline (Point Pleasant, NJ to Longport, NJ) from 1839 to 2012. Shoreline data were obtained from multiple data sources, including the U.S. Geological Survey (USGS), National Oceanic and Atmospheric Administration (NOAA), and New Jersey Department of Environmental Protection (NJDEP). Datasets were compiled and analyzed using the R package Analyzing Moving Boundaries Using R (AMBUR) program. Rates of shoreline change can be used for evaluating living shoreline resources, decision-making for future resource and urban planning, and restoration of both protected and open-ocean shorelines.
Purpose:
The purpose of these data is to examine the shoreline change rates for Barnegat and Great Bay, New Jersey.

Data_Set_Credit:
Acknowledgment of the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center, as a data source would be appreciated in products developed from these data, and such acknowledgment as is standard for citation and legal practices. Sharing of new data layers developed directly from these data would also be appreciated by the U.S. Geological Survey staff. Users should be aware that comparisons with other datasets for the same area from other time periods may be inaccurate due to inconsistencies resulting from changes in photointerpretation, mapping conventions, and digital processes over time. These data are not legal documents and are not to be used as such.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Shoreline change rates are influenced by availability and accuracy of shoreline data. Analyses of highly dynamic areas are particularly challenging, including 1) areas near inlets, where there is excessively dynamic depositional/erosional sand bars that may appear/disappear rapidly, and 2) stretches of backshore where overwash fans can form islands that are difficult to resolve and distinguish from barrier islands themselves. The End Point Rate (EPR) and Linear Regression Rate (LRR) were compared to identify and correct significant errors in the shoreline change rate.
Logical_Consistency_Report:
Vector features and attributes were checked for completeness and accuracy. Linework is generated by the "Construct transects" and "Filter transects" algorithm in the AMBUR program and are generally perpendicular to the shorelines. However, where shorelines experience sharp bends, such as in small bays and narrow spits, the filter algorithym can create transects that are not perpedicular to the shoreline.
Completeness_Report:
Dataset is considered complete for the information presented. Some dated shorelines do not have complete coverage over the entire study area (for example, 1839 shorelines were available for the estuarine shorelines of Long Beach Island, but not for the Barnegat Bay mainland region); however, this was acceptable as the analysis method accounts for the available dates only. Users are advised to read the rest of the metadata record carefully for additional details.

Process_Description:
Transects were generated by buffering the available shoreline datasets to create inner (land based) and outer (water based) baselines. The baselines form the start and end point for shoreline-perpendicular transects. Baselines were input into the AMBUR statistical package for R (version 3.3.2). AMBUR has several tools, which utilize shoreline parallel baselines to generate transects that are generally perpendicular to the shoreline. Transects were constructed at a sampling distance of 50 meters. Length varied from 1000 to 3000 meters, depending on location, and was selected to cover all dated shorelines. Once transects were created, the Filter Transects tool was used to adjust and even out the spread of transects. Where shorelines experience sharp bends, such as in small bays and narrow spits, transects may fall at a non-perpendicular angle. Final transects were checked and edited in ArcGIS (Version 10.3), if necessary, in order to improve analysis results and improve shoreline coverage. Transects were manually edited to reduce errors in the analyses. Shoreline points and final statistical analyses were completed in AMBUR to generate the shoreline change rates. The following analysis parameters were used: fist intersection (if transect intersects the same shoreline more than once, then by dfault it selected the first intersection), confidence level 95 (confidence level for the linear regression statisics), unit label m (the units of measure for the map is for UTM and in meters), analysis type is advanced (advanced includes additional statistics for a robust linear regression), and time unit for rates is yr (utilizes years for calculating rates of shoreline change).

Overview_Description:
Entity_and_Attribute_Overview:
The entity and attributes in these datasets are compiled and generated by the AMBUR program given the input shoreline dataset and transects. No data values are left blank. Field descriptions with "NA" are used for AMBUR processing only and do not provide information that is useful for analysis. All distance units are in meters and time unites are in years. Therefore, rates of change would be in meters per year. For attribute definitions, see p. 37 of: Jackson, C.W., Jr., 2010.
