Description:
Abstract:
This shapefile consists of Fire Island, NY pre- and post-storm shoreline data collected from October 2012 to September 2014. This dataset contains 13 Mean High Water (MHW) shorelines for Fire Island, NY (A total of 15 dates, where two shorelines were collected over multiple days). Prior to and following Hurricane Sandy in October, 2012, continuous alongshore DGPS data were collected to assess the positional changes of the shoreline (MHW - 0.46 m NAVD88) and the upper portion of the beach. Over the course of 23 months, 13 surveys were conducted collecting data along shore-parallel tracks to capture the base of the dune, the mid-beach, and the upper and lower foreshore. The alongshore tracks extend from just west of Fire Island Lighthouse to the western flank of the storm-induced inlet breach at Old Inlet.
The MHW shoreline (0.46 m North American Vertical Datum of 1988 [NAVD 88]; Weber and others, 2005) is derived from the field data by using an interpolation method that creates a series of equally-spaced cross-shore profiles between the two survey lines that flank the MHW contour. The foreshore slope is assumed to be uniform on each profile. Using this slope and the two surveyed positions on each cross-shore profile, a simple geometric calculation is done to find where each profile line intersects the MHW contour.
Purpose:
The U.S. Geological Survey (USGS) mounted a substantial effort in response to Hurricane Sandy including an assessment of the morphological impacts to the beach and dune system at Fire Island, New York. Field surveys of the beach and dunes collected just prior to and after the U.S. landfall, which occurred on October 29th, 2012, were used to quantify change in several focus areas.
The migration of the shoreline through time is assessed by quantifying the net shoreline movement (NSM) over different time periods by using the interpolated MHW shorelines and 50 m spaced transects in the Digital Shoreline Analysis System (DSAS; Thieler and others, 2009).

Attribute_Accuracy_Report:
The data provided here is a compilation of shorelines that were derived using USGS-specific field-collection methods over the course of 23 months following hurricane Sandy, which made landfall in New Jersey on October 29, 2012. The table attributes associated with Shorelines_Oct2012_Sept2014.shp are based on the requirements of the Digital Shoreline Analysis System (DSAS) software and have gone through a series of quality assurance procedures. For more information see <http://woodshole.er.usgs.gov/project-pages/DSAS/>

Logical_Consistency_Report:
Adjacent shoreline segments do not overlap and are not necessarily continuous. Shorelines were quality checked for accuracy.
Completeness_Report:
This shoreline file is complete and contains all shoreline segments derived from Pre and Post-Sandy data collection efforts. These data adequately represented the shoreline position at the time of the survey.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
In order to determine the uncertainties associated with individual shorelines, a methodology following Morton and Miller (2005) and Hapke and others, (2006) was used to estimate a positional error value for each shoreline. The shoreline position uncertainty is estimated using a square root of the sum of the squares of multiple terms. Total shoreline positional error is a function of the errors inherent in the source data/data collection, and those errors generated in the creation and identification of the vector shoreline. The specific terms used in the calculation will be: 1) Predicted MHW uncertainty - an estimate of interpolated shoreline position accuracy based on the slope, and distance between track lines (1 - 2.5 m); 2) Average measured MHW error - the manual measurement of MHW shoreline compared to the position of MHW on the cross-shore profiles (1 - 7.5 m); 3) Collection error - derived from static portions of each survey (0.07 - 0.12 m); 4) And finally an estimated error based on slope of the beach (0.02 - 0.1 m)
Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Value: 3.5
Horizontal_Positional_Accuracy_Explanation:
Each shoreline was assigned a unique uncertainty based on 1) Predicted MHW uncertainty; 2) Average measured MHW error; 3) Collection error; 4) And finally an estimated error based on slope of the beach.
The following are the estimated uncertainties for each date. Values are in meters NAVD88.

Title: FIIS DGPS shoreline data
Geospatial_Data_Presentation_Form: tabular digital data
Other_Citation_Details:
In order to examine the dynamics of the shoreline from Hurricane Sandy and monitor the continued response and recovery, surveys of continuous alongshore differential global positioning system (DGPS) data were collected in conjunction with cross-shore profiles. Multiple shore-parallel tracks were driven to capture the base of the dune, the mid-beach, and the upper and lower foreshore along the length of the island from Fire Island lighthouse to the western side of the storm-induced inlet breach at Old Inlet.
Initial surveys were conducted one day prior to landfall and immediate post-storm surveys were conducted over the three days following Hurricane Sandy. The beaches and dunes were resurveyed monthly from December 2012 through April 2013, and bi-monthly surveys are presently ongoing. The USGS is continuing to monitor the beaches and dunes to evaluate how much of the sand removed by Sandy returns to the beach via natural beach-building processes.

MHW Shoreline interpolation from tabular DGPS Data (October 28 2012-Dec 2013)
Continuous alongshore DGPS data were collected to assess the positional changes of the MHW shoreline and the upper portion of the beach. Data were collected along shore-parallel tracks to capture the base of the dune, the mid-beach, and the upper and lower foreshore. For each survey date, ASCII point data was imported into Matlab (v R2012a) and processed as follows:
For surveys October 28 2012-Dec 2013 the MHW shoreline (0.46 m North American Vertical Datum of 1988 [NAVD 88]; Weber and others, 2005) is derived from the field data by using an interpolation method that creates a series of equally-spaced cross-shore profiles between the two survey lines that flank the MHW contour. The foreshore slope is assumed to be uniform on each profile. Using this slope and the two surveyed positions on each cross-shore profile, a simple geometric calculation is done to find where each profile line intersects the MHW contour. At this interesection a point is generated, and the series of points making up the MHW shoreline are appended to create a polyline shoreline.
The resulting ployline shapefile (for each method) was named FIIS_shoreline_DATE, where date is the date of the field survey. For example: MHW extracted polyline for October 28 2012 would be named FIIS_shoreline_2012Oct28.shp

MHW Shoreline interpolation from tabular DGPS Data (Jan 2014 - Sept 2014)
Continuous alongshore DGPS data were collected to assess the positional changes of the MHW shoreline and the upper portion of the beach. Data were collected along shore-parallel tracks to capture the base of the dune, the mid-beach, and the upper and lower foreshore. For each survey date, ASCII point data was imported into Matlab (v R2012a) and processed as follows:
For surveys January 2014 and beyond, a new, survey approach was implemented that was designed to improve surface interpolation by collecting a more dense network xyz points along the beach face. For these surveys, alongshore transects are collected at the berm crest, low water mark and mid-beach face. In addition, a sinusoidal transect is collected by driving from the water’s edge to the top of the berm crest at approximately 45 degrees to the orientation of the shoreline. The xyz data are used to create an interpolated surface from which the MHW contour is extracted.

The resulting ployline shapefile (for each method) was named FIIS_shoreline_DATE, where date is the date of the field survey. For example: MHW extracted polyline for October 28 2012 would be named FIIS_shoreline_2012Oct28.shp

Calculation of shoreline uncertainty: In order to determine the uncertainties associated with individual shorelines, a methodology following Morton and Miller (2005) and Hapke and others, (2006) was used to estimate a positional error value for each shoreline. The shoreline position uncertainty is estimated using a square root of the sum of the squares of multiple terms. Total shoreline positional error is a function of the errors inherent in the source data/data collection, and those errors generated in the creation and identification of the vector shoreline.
Oct 2012–Dec 2013 The terms used for the interpolated shorelines derived from October 2012 to December 2013 were: 1) predicted MHW uncertainty - an estimate of interpolated shoreline position accuracy based on the slope, and distance between track lines (1 - 2.5 m); 2) average measured MHW error - the positional difference between the interpolated MHW shoreline and the location of the MHW elevation on the cross-shore profiles from the same survey date (1 - 7.5 m); 3) collection and equipment error - derived from static portions of each survey (0.07 - 0.12 m); 4) A term to account for horizontal positional variation found when driving the GPS (horizontal to the Polaris) on a sloped surface (0.02 - 0.1 m). Individual shoreline uncertainties are found in the shapefile “ACCURACY” attribute and in the metadata file.
Jan 2014–Sept 2014 For surveys January 2014 and September 2014 the MHW elevation was extracted from a surface generated from field collected data points. The terms used to estimate error for the extracted shorelines were: 1) average measured MHW - the positional difference between the interpolated MHW shoreline and the location of the MHW elevation on the cross-shore profiles from the same survey date (2.2-3.2 m; Sept 2014 used an average of previous time periods, as a large displacement of MHW due to high waves occurred in the day between shoreline and profile surveys); 2) collection and equipment error - derived from static portions of each survey (0.07 - 0.1 m); and 3) uncertainty of the interpolated surface estimated by withholding 10% of the original data points and calculating an root mean square error (RMSE) of the difference between the withheld points and the surface (0.04 – 0.06 m). Individual shoreline uncertainties are found in the shapefile “ACCURACY” attribute and in the metadata file.
