Introduction In 2012, Hurricane Sandy created an open breach in the barrier island system along the south shore of Long Island, N.Y. This breach formed at a location known as Old Inlet and migrated rapidly westward over the winter storm season following Hurricane Sandy. In response, the National Park Service sought assistance from the USGS New York Water Science Center to help evaluate the hydrodynamics and geomorphology of the breach. The evaluation is centered on measurement of water velocities and depths within the breach, and collection of water levels with the Great South Bay adjacent to the breach. This project is part of a larger ongoing study prepared in coordination with the National Park Service...

The Bathymetry surface was created by plotting depths of all data points collected relative to North American Vertical Datum of 1988 (NAVD 88), which was converted using the Vertical Datum Transformation tool created by the National Oceanic and Atmospheric Administration's (NOAA) National Geodetic Survey, Office of Coast Survey, and Center for Operation Oceanographic Products and Services. The elevation of the bathymetric raster surface was interpolated between these points in a GIS using a spline interpolator. A total of 432 points were used for interpolation. The points were used as the input to create a polygon feature class. The Spline tool was applied using the points and polygon to interpolate the bathymetric...

This dataset represents the location of tidal inlets and beaches opened and closed by Hurricane Sandy on October 29, 2012, from the Storm-induced Habitat Modifications caused by Hurricane Sandy within the U.S. Atlantic Coast Breeding Range of the Piping Plover (Charadrius melodus) project. Tidal inlets were located along the U.S. North Atlantic coast from Maine to North Carolina using aerial imagery from Google Earth, NOAA-NGS, USGS and PSDS that was taken from October 31 to November 9, 2012. Comparison to the locations of tidal inlets that were open prior to Hurricane Sandy as described in three previous reports allowed for the identification of inlets or breaches that were opened or closed by Hurricane Sandy....

Data collected during the May 14th 2015 ADCP survey were processed using a Geographic Information System for interpolation and display. The shapefile available for download depicts ADCP data points collected on May 14, 2015. Parameters include depth, velocity, and discharge collected at 1 second intervals. Ebb data points were collected during outgoing tide.
