Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate. Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion. As a result, there is an increased demand for accurate information regarding past and present shoreline changes. To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.
There is no widely accepted standard for analyzing shoreline change. Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments. The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast. The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.
This dataset consists of short-term (~30 years) shoreline change rates for the New Jersey North region from Sandy Hook to Little Egg Inlet, New Jersey. Rate calculations were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 4.1, an ArcGIS extension developed by the U.S. Geological Survey. Short-term rates of shoreline change were calculated using an end-point rate method based on shorelines from 1977 and 2000 to provide an approximately 30-yr short-term rate. A reference baseline was used as the originating point for the orthogonal transects cast by the DSAS software. The transects intersect each shoreline establishing measurement points, which are then used to calculate short-term rates.

The attributes of this dataset are based on the field requirements of the Digital Shoreline Analysis System and were automatically generated by the software during the generation of the transect layer or during the calculation of shoreline change rates performed by the software.
These data were generated using DSAS v4.1, an automated software program which does not perform checks for fidelity of the input features. The transects were visually inspected and sometimes manually adjusted within a standard ArcMap edit session to adjust the position at which an individual transect intersected the shorelines.
This dataset contains the transects automatically generated by the DSAS software application that were used to calculate short-term shoreline change rates for the region. Additional transects may have been generated but did not intersect the two shoreline dates specified (1977 and 2000 years) to calculate short-term rates.
Transect Features Generated using DSAS v4.1 in ArcMap v9.3. Parameters Used: baseline layer=NewJerseyS_baseline, baseline group field=NULL, transect spacing=50 meters, transect length=1500 meters, cast direction=AUTO-DETECT, baseline location=offshore, cast method=two leg, smoothing distance=50 meters, flip baselines=not selected. For additional details on these parameters, please see the DSAS help file distributed with the DSAS software, or visit the USGS website at: https://pubs.er.usgs.gov/publication/ofr20081278. This process step and all subsequent process steps were performed by the same person: Emily Himmelstoss.

Rate Calculations Performed in DSAS v4.1 using ArcMap v9.3 on Selected Shoreline Features Only (1977 and 2000). Parameters Used: shoreline layer=NewJerseyS_shorelines, shoreline date field=Date_, shoreline uncertainty field name=Uncy, the default accuracy=10.8 meters, shoreline intersection parameters=nearest, stats calculations=[End Point Rate (EPR)], shoreline threshold=none, confidence interval=90%, Output rate table name=NewJerseyS_transects_rates_20100414_115107.
20100414
Shoreline rates table (NewJerseyS_transects_rates_20100414_115107.dbf) was joined to the transect feature class in ArcMap v9.3 by right-clicking on the transect layer > joins and relates > join > join attributes from a table. Parameters: join field - ObjectID; table to join - NewJerseyS_transects_rates_20100414_115107; field in table: TransectID; join options - keep only matching records.
20100414
The joined transect feature class was exported to a shapefile in ArcMap v9.3 by right-clicking the transect layer > data > export data, permanently linking the joined rate fields to the transect attribute table.
20100414
The exported transect shapefile was projected in ESRI's ArcToolbox (v.9.3) > Data Management Tools > Projections and Transformations > Feature > Project. Parameters: input projection - UTM zone 19N (NAD 83); output projection - geographic coordinates (WGS84); transformation - NAD_1983_To_WGS_1984_1.

Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Added an online link to the data in the identification section. Fixed cross-reference online links. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. Attempted to modify http to https where appropriate. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
