Abstract:
Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida, collected bathymetric data along the upper shoreface and within the wilderness breach at Fire Island, New York, in June 2014. The U.S. Geological Survey is involved in a post-Hurricane Sandy effort to map and monitor the morphologic evolution of the shoreface along Fire Island and model the evolution of the wilderness breach as a part of the Hurricane Sandy Supplemental Project GS2-2B.During this study, bathymetry was collected with single-beam echo sounders and global positioning systems, mounted to personal watercraft, along the Fire Island shoreface and within the wilderness breach. Additional bathymetry was collected using backpack global positioning systems along the flood shoals and shallow channels within the wilderness breach.
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 June 10-20, 2014. The objectives of the data collection were to map the morphology of the shoreface and the wilderness breach as part of the USGS Hurricane Sandy Supplemental Project GS2-2B. This dataset, 201406_Single_Beam_XYZ_Shoreface.zip, consists of nearshore, single-beam horizontal position and vertical elevation data collected along the shoreface, onboard two personal watercraft (PWC) vessels.

Attribute_Accuracy:
Attribute_Accuracy_Report:
The accuracy of the data is determined during data collection. This dataset is derived from a single field survey using identical equipment, set-ups, and staff; therefore, the dataset is internally consistent. Methods are employed to maintain data collection consistency aboard the mount. During mobilization, 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, the distance between the transducer and the GPS antenna was measured for each personal watercraft and accounted for during post-processing. For the base stations, the Ashtech ProFlex 500 system has a long static horizontal accuracy of 0.3 centimeters (cm) and 0.6 cm vertical accuracy. For the rovers, the post-processed kinematic horizontal instrument accuracy is 1 cm, and vertical accuracy is 2 cm. The Echotrac CV100 Digital Hydrographic Echo Sounder has a vertical accuracy of 0.01 m 0.1% depth.

Horizontal_Positional_Accuracy_Report:
The GPS antenna and receiver acquisition configuration used at the reference station was duplicated on the survey vessel (rover). The base receiver and the rover receiver record their positions concurrently at 10Hz recording intervals throughout the survey. All processed measurements are referenced to the base station coordinates. All static base station GPS sessions were submitted for processing to the NOAA/NGS OPUS software. OPUS results provide an error measurement for each daily solution with a horizontal accuracy estimated as 0.4 cm root mean squared (RMS). The combined horizontal uncertainty is assumed to be at most half of the vertical.

Process_Description:
GPS Acquisition: GPS base stations were erected at benchmarks REST (near the town of Robins Rest) and U374 (NGS benchmark Permanent Identification number (PID#) KU0206) located on Fire Island. Base stations were equipped with Ashtech ProFlex 500 Global Navigation Satellite System (GNSS) receivers. The survey personal watercraft (PWC) (rovers) were equipped with ProFlex 500 GNSS receivers. The base and rover receivers recorded their positions concurrently at 10 Hertz (Hz) throughout the survey. Reference stations coordinates were verified with Continuously Operating Reference Station (CORS) sites using the Online Positioning User Service (OPUS), available at http://www.ngs.noaa.gov/OPUS/). U374 used reference stations ZNY1, NYRH, CTDA, while REST used stations NYCI, NYRH, and MOR6. OPUS computed both reference stations had horizontal errors of 0.4 cm and vertical errors of 0.2 cm.

Process_Description:
Single-Beam Sounding Acquisition: The single-beam bathymetric data were collected on two Yamaha (2010 and 2013) VX Deluxe personal watercraft. Each PWC was fitted with a single-beam transducer below the waterline off the starboard stern, 1.11 m beneath the GPS antenna position. HYPACK version 2013 was used for positioning and navigation during the survey. Depth soundings were recorded at 10 Hertz (Hz), using an Odom Ecotrac CV-100 Digital Hydrographic Echo Sounder system with 200 kHz transducers with 4-degree (10 June 2014) and 9-degree (remainder of survey) 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) meter. Data were processed using SonTek CastAway CTD software version 1.5.

Process_Description:
Single-Beam Differentially Corrected Navigation Processing: Horizontal positions and vertical elevations associated with each single-beam sounding were post-processed using differential corrections derived from the base/rover setup. Two GPS reference stations were used for the survey and were located at benchmarks U374 and REST. Applying the reference station coordinates, GPS data acquired from the rover were processed to the concurrent GPS session data at the base station- using GrafNav version 8.5 software (Waypoint Product Group). The horizontal and vertical coordinates were recorded in the World Geodetic System of 1984 (WGS84) reference frame and exported as an ASCII file for each personal watercraft and each survey day.

Process_Description:
Single-Beam Data Processing: Single-beam soundings were merged with differentially processed GPS data and sound velocity profiles using Matlab R2014b. Each transect was visually inspected for elevation outliers and dropouts associated with wave breaking in the surf zone were manually corrected. Typically, the highest intensity return is generated by the seafloor surface. Breaking waves in the surf zone can create air bubbles in the water column and create an erroneous peak in waveform intensity, which causes errors in the interpreted seafloor reflection. When this situation was 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 corrected for the average speed of sound (table 1). A moving average filter was applied to the soundings to reduce instrument noise and the noise associated with the pitch and roll of the PWC. The depth soundings (from the transducer to the seafloor) were then adjusted to the depth from the GPS antenna and subsequently to the WGS84 ellipsoid.

Single-Beam Datum Transformation: NOAA's VDatum v3.3 was used to transform single-beam data points(x,y,z data) from their data acquisition datum (WGS84) to the North American Datum of 1983 (NAD83) reference frame and the North American Vertical Datum of 1988 (NAVD88) elevation using the National Geodetic Survey (NGS) geoid model of 2012A (GEOID12A). For conversion from the WGS84 ellipsoid to NAVD88 there is a total of 5.4 cm of uncertainty in the transformation (http://vdatum.noaa.gov/docs/est_uncertainties.html).

Single-Beam Error Analysis: The accuracy of the single-beam soundings was evaluated by identifying locations where survey track lines crossed and soundings from each line were horizontally within 0.25 m of each other. Any track line with a root mean square (RMS) error of 12.2 cm for a total of 732 crossings. Since the mean error between wave runners was 0.5 cm, which is below the minimum resolution of the echosounder, no correction offset was applied to the individual echosounders. Applying the square root of the sum of the datum conversion uncertainty and the sounding uncertainty resulted in a combined vertical error of 13.3 cm. Horizontal uncertainty is assumed to be half of the vertical uncertainty (6.7 cm) at most.
