During this study, bathymetry data were collected aboard two personal watercraft (PWC) outfitted with single-beam echosounders, as well as a towed seismic sled with similar instrumentation. Purpose: To evaluate shoreface morphology along the Rockaway Peninsula, New York, scientists from the USGS SPCMSC conducted a bathymetric survey during Field Activity Number (FAN) 2019-333-FA. The objectives of the data collection effort were to map shoreface morphology in support of the National Fish and Wildlife (NFWF) Beach and Marsh Monitoring Project and the USGS Coastal Sediment Availability and Flux (CSAF) Project. This dataset, Rockaway_2019_SBES_xyz.zip consists of single-beam horizontal position (x,y) and vertical (z) elevation data collected along the nearshore zone of the Rockaway Peninsula. Additional survey and data details are available from the Coastal and Marine Geoscience Data System (CMGDS) at, https://cmgds.marine.usgs.gov/fan_info.php?fan=2019-333-FA. Supplemental_Information: For the single-beam bathymetry data, the differential positioning was obtained through post-processing the base station data to the rover. This dataset, Rockaway_2019_SBES_xyz.zip, was transformed from the initial World Geodetic System of 1984 (WGS84) G1762 datum to the North American Datum of 1983 (NAD83) North American Vertical Datum of 1988 (NAVD88), using the GEOID12B model (National Oceanic and Atmospheric Administration (NOAA) National Geodetic Survey (NGS) Transformation software VDatum, version 4.1 - http://vdatum.noaa.gov/).

Native_Data_Set_Environment: Environment as of Metadata Creation: Microsoft Windows 10 Version 1709 (Build 16299.666) Service Pack 1; Environmental Systems Research Institute (Esri) ArcGIS 10.6.0.8321 Data_Quality_Information: 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 similar equipment, set-ups, and staff; therefore, the dataset is internally consistent. Methods are employed to maintain data collection consistency aboard the platforms. During mobilization, each piece of equipment was isolated to obtain internal and external offset measurements with respect to the survey platform. All the critical measurements were recorded manually and then digitally entered into their respective programs. Offsets between the single-beam transducers, motion reference units, and the Ashtech antenna reference point (ARP) were measured and accounted for in post-processing. Differential Global Positioning System (DGPS) coordinates were obtained through post-processing using the software Online Positioning User Service (OPUS) maintained by the NOAA and the NGS, and Waypoint Product Group GrafNav, version 8.7. Logical_Consistency_Report: These datasets are from one field activity with consistent instrument calibrations. Completeness_Report: This data release contains horizontal position and vertical elevation (x,y,z) single-beam data from September - October 2019, collected within the nearshore waters of the Rockaway Peninsula, New York. Users are advised to read the complete metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: All static base station sessions were processed through OPUS. The OPUS solutions were entered into a spreadsheet to compute a final, time-weighted position (latitude, longitude, and ellipsoid height) for the utilized base stations. The time-weighted position for the USGS established benchmark RIIS, a P/K nail installed in the dockage area of the former Riis Landing U.S. Coast Guard Station, was calculated and used in subsequent processing steps. Accuracy pertaining to the base station horizontal coordinates is as follows: Horizontal = 0.000009 seconds (s) or approximately 0.002 meters (m). An additional base station was erected on a USGS established benchmark FLYD, a P/K nail installed on the retired air strip of Floyd Bennett Field. FLYD served as a secondary base station and was not used in final processing. The kinematic (rover) trajectories were processed using GrafNav version 8.70 software by Novatel, Inc. Transformed data have an additional reported horizontal transformation error of 7.6158 centimeters (cm). Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: All static base station sessions were processed through OPUS.

Transformed data have an additional reported vertical transformation error of 7.6158 cm. Lineage: Process_Step: Process_Description: GPS Acquisition: Two Global Positioning System (GPS) base stations were established near the survey area. The primary base station, RIIS, is a USGS installed P/K nail located in the dockage area of the former Riis Landing U.S. Coast Guard Station located just west of the Marine Parkway Bridge on the Rockaway Peninsula. The secondary station, FLYD, was an additional USGS installed P/K nail located on the retired airstrip of Floyd Bennett Field, located in southeast Brooklyn, New York City. The base stations were continually occupied and equipped with a Spectra Precision SP90M (RIIS) and a Spectra Precision Proflex 800 (FLYD) GPS receiver recording full-carrier-phase positioning signals (L1/L2) from satellites via Thales Choke-ring antennas, recording at a rate of 0.1 s.

A total of 399.76 line-km (240 lines) were surveyed. Boat motion was recorded at 50-millisecond (ms) intervals using an SBG motion sensor. HYPACK (version 18.1.8.0), a marine surveying, positioning, and navigation software package, managed the planned-transect information and provided real-time navigation, steering, correction, data quality parameters, and instrumentation-status information to the vessel operator. Depth soundings were recorded at 50-ms intervals using an Odom Echotrac CV100 sounder with a 4 degree, 200-kilohertz (kHz) transducer. Data from the GPS receiver, motion sensor, and fathometer were recorded in real-time aboard the platform independently and merged into a single raw data file (*.RAW) in HYPACK, with each device string referenced by a device identification code and time stamped to Coordinated Universal Time (UTC). Sound velocity profile (SVP) measurements were collected using three separate SonTek Castaway conductivity, temperature, and depth (CTD) instruments deployed from each survey platform. The instruments were periodically cast overboard to observe changes in water column speed of sound (SOS). A total of 49 successful sound velocity casts were taken throughout the survey at an average depth of 3.13 m, and on average produced a sound velocity of 1514.25 meters per second (m/s).

The base station coordinates were imported into GrafNav version 8.7 and the kinematic GPS data from the survey platform were post-processed to the concurrent GPS session data at the base station. During processing, steps were taken to ensure that the trajectories between the base and the rover were clean, resulting in fixed positions. By analyzing the graphs, trajectory maps, and processing logs that GrafNav produces for each GPS session, GPS data from satellites flagged by the program as having poor health or satellite time segments that had cycle slips could be excluded, or the satellite elevation mask angle could be adjusted to improve the position solutions. The final differentially corrected, precise DGPS positions were computed at 0.1 s and exported in American Standard Code for Information Interchange (ASCII) text format. In subsequent processing steps, these data will replace the uncorrected, real-time rover positions. The GPS data were processed and exported in the WGS84 (G1762) geodetic datum.

The raw HYPACK data files were imported into CARIS, the differentially corrected navigation files were imported using the generic data parser (GDP) tool, and any SVP profile casts were entered and edited using the SVP editor. The bathymetric data components (position, motion, depth, and SOS) for all data were then merged and geometrically corrected in CARIS to produce processed x,y,z data. Next, the data were edited for outliers and then further reviewed in the Subset Editor utility for crossing status, and questionable data points or areas. The geometrically corrected point data were then exported as an x,y,z ASCII text file referenced to WGS84 (G1762), ellipsoid height in meters.

First, all data were visually scanned for any obvious outliers or problems. Next, a track line shapefile was produced using X-tools Pro "Make Polylines from Points" function. Utilizing both the x,y,z (point) and track line (polyline) shapefiles, an in-house Python script evaluated elevation differences at the intersection of crossing track lines by calculating the elevation difference between points at each intersection using an inverse distance weighting equation with a search radius of 1 m. The calculated RMS errors when a vessel crosses a track line previously surveyed is as follows: WVR1 (19CCT05) = 7.1 cm, WRV2 (19CCT06) = 8.30 cm, and the Sled (19CCT07) = 5.1 cm, respectively. Once individual platform statistics were obtained, all x,y,z data were merged into a single shapefile and a crossing analysis preformed, which yielded an 8.16 cm RMS error. Since the bias between the platform elevations was on the order of the Odom instrument accuracy (1 cm +/- 0.7 percent depth), no adjustments were made. The merged file was exported from Esri ArcMap as an x,y,z text (.txt) file and made available in the download section of this data release, along with the populated track line shapefiles.
