The U.S. Geological Survey is involved in a post-Hurricane Sandy effort to map and monitor the morphologic evolution of the wilderness breach, which formed in October 2012 during Hurricane Sandy, as part of the Hurricane Sandy Supplemental Project GS2-2B. During this study, bathymetry data were collected, using single-beam echo sounders and global positioning systems mounted to personal watercraft, along the Fire Island shoreface and within the wilderness breach, Fire Island Inlet, Narrow Bay, and Great South Bay east of Nicoll Bay. Additional bathymetry and elevation data were collected using backpack and wheel-mounted global positioning systems along the subaerial beach (foreshore and backshore), and flood shoals and shallow channels within the wilderness breach and adjacent shoreface. Purpose: To determine the change Hurricane Sandy caused in the shoreface morphology and breach evolution at Fire Island, New York, USA, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted a bathymetric survey of Fire Island from October 5 to 10, 2014. The objectives of the data collection effort were to map the morphology of the wilderness breach and adjacent shoreface, Fire Island Inlet, Narrow Bay, and Great South Bay east of Nicoll Bay the shoreface as part of the USGS Hurricane Sandy Supplemental Project GS2-2B. This dataset, 201410_Single_Beam_XYZ_Shoreface.zip, consists of single-beam elevation and global positioning system (GPS) data collected with personal watercraft (PWC).

This dataset is derived from a single field survey using identical equipment, setup procedures, and staff; therefore, the dataset is internally consistent. Methods are employed to maintain data collection consistency. During setup, each piece of equipment is isolated to obtain internal and external offset measurements with respect to the survey platform. All the critical measurements are recorded manually and digitally entered into their respective programs. For single-beam soundings, distance between the transducer and GPS antenna were measured for each personal watercraft and accounted for during post-processing. Logical_Consistency_Report: The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center collected shallow water bathymetric data in the wilderness breach, Bellport Bay, Narrow Bay, Great South Bay east of Nicoll Bay, Fire Island Inlet, and the ocean shoreface within approximately 2.5 kilometers (km) of the wilderness breach. Single-beam soundings were collected in the wilderness breach (and associated flood and ebb tidal shoals), Fire Island Inlet, Narrow Bay, and the eastern end of Great South Bay. This zip archive contains the post-processed single-beam bathymetric data (x, y, z) acquired during a single field survey, in October 2014. Completeness_Report: This is a complete post-processed x,y,z bathymetric data point file acquired with personal watercrafts along the shoreface of Fire Island, NY. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The GPS antenna and receiver acquisition configuration used at the base station was duplicated on the survey vessel (rover). The base receiver and the rover receiver recorded their positions concurrently at 10 hertz(Hz) recording intervals throughout the survey. All processed measurements were referenced to the base station coordinates. All static base station GPS sessions were submitted for processing to the Online Positioning User Service (OPUS), which was created by the National Oceanic and Atmospheric Administration/National Geodetic Survey (NOAA/NGS). OPUS results provided an error measurement for each daily solution with a horizontal accuracy estimated as 0.007 m root mean squared (RMS). The combined horizontal error was assumed to be at most half of the vertical offset. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 0.087 m Horizontal_Positional_Accuracy_Explanation: Static GPS data were processed using NOAA/NGS OPUS software and kinematic GPS data were processed with GrafNav v8.50 software by Novatel and Matlab. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The GPS antenna and receiver acquisition configuration used at the base station was duplicated on the survey vessel (rover). The base receiver and the rover receiver recorded their positions concurrently at 10 Hz recording intervals throughout the survey. All processed measurements were referenced to the base station coordinates. OPUS results provided an error measurement for each daily solution. Applying these error measurements, the vertical accuracy of the base station was estimated to be 0.007 m root mean squared (RMS). The kinematic (rover) trajectories were processed using GrafNav v8.50 software by Novatel and Matlab. Occurrences where a personal watercraft trackline crosses itself were used to determine vertical error. The calculated RMS error was 0.165 M. The combined vertical error from base station coordinate solutions, rover trajectories, and datum transformations is 0.174 m. Quantitative_Vertical_Positional_Accuracy_Assessment: Vertical_Positional_Accuracy_Value: 0.174 m Vertical_Positional_Accuracy_Explanation: Static GPS data were processed using NOAA/NGS OPUS software and kinematic GPS data were processed with GrafNav v8.50 software by Novatel and Matlab. Lineage: Process_Step: Process_Description: GPS Acquisition: Horizontal and vertical positioning of each vessel and backpack was were collected determined using a base-rover configuration. Data were recorded at 10 Hertz (Hz) using Ashtech ProFlex™ 500 Global Navigation Satellite System (GNSS) receivers with Thales choke ring antennas. Three stationary base stations (REST, VC, and U374) were occupied during the surveys. The stationary base at published NGS benchmark U374 (Permanent Identification number (PID#) KU0206) was equipped with an Inmarsat Broadband Global Area Network (BGAN) satellite uplink system for remote monitoring of the base station. U374 consisted of an Ashtech Proflex 500 GNSS receiver and an Ashtech choke ring antenna with a vertical offset of 1.24 meters (m). GPS data acquired by the PWCs, backpack, wheel-mount, and the REST and VC base stations were downloaded at the end of each survey day. A small segment of the U374 data was downloaded via the BGAN network nightly to ensure the system was operating properly. Reference station coordinates were verified with Continuously Operating Reference Stations (CORS) stations using OPUS, (http://www.ngs.noaa.gov/OPUS/). OPUS computed reference positions had a vertical error of 0.007 m and horizontal errors of 0.8 cm and 0.6 cm for East-West and North-South, respectively.

HYPACK version 2013 was used for positioning and navigation during the survey. Depth soundings were recorded at 10 Hz using an Odom Ecotrac CV-100 Digital Hydrographic Echo Sounder system with 200 kHz transducers with 4-degree (vessel 1) and 9-degree (vessel 2) transducers. Soundings were merged into a raw data file (.raw) and a sounding file (.bin) in HYPACK. Each file was named according to transect number and coordinated universal time (UTC). Water column sound velocity measurements were collected periodically throughout the survey, using a SonTek CastAway conductivity, temperature, and depth (CTD) sensor. Data were processed using SonTek CastAway CTD software version 1.5.

When this is suspected, a corrected seafloor elevation was manually digitized by analyzing the complete waveform signal recorded by the Odom within the .bin data file. The soundings were then corrected for the speed of sound associated with the mean water temperature and salinity. A moving average filter was then applied to the soundings in order to reduce instrument noise and noise associated with the pitch and roll of the PWC. The soundings were referenced to the height of the GPS antenna and subsequently to the WGS84 ellipsoid.

Any track line associated with a crossing that had an elevation differing by greater than 0.6 m, compared to crossing lines, was removed. Evaluation of the remaining track line crossings indicated there was an overall mean difference of 3.8 cm (based on 210 crossings) and (root mean square) RMS error of 16.5 cm (based on 696 crossings). Applying the square root of the sum of the datum conversion uncertainty (5.4 cm) and the sounding uncertainty (16.5 cm) results in a combined vertical error of 17.4 cm. Horizontal uncertainty is assumed to be at most half of the vertical uncertainty (8.7 cm).
