During this study, single-beam bathymetry data were collected using a personal watercraft (PWC) and a floating-towed-seismic sled. Both the PWC and the seismic sled were outfitted with high precision Global Navigation Satellite System (GNSS) receivers, motion reference units, and survey grade single-beam echosounders. Purpose: The purpose of this data release is to archive the bathymetric data and associated files collected off Seven Mile Island from April 29 - May 2, 2022, during Field activity number (FAN) 2022-309-FA; subFANs 22BIM05 (research vessel [R/V] Sallenger towing a floating seismic-sled) and 22BIM03 (R/V Chum – WVR2). Additional survey and data details are available in the Coastal and Marine Geoscience Data System (CMGDS) at, https://cmgds.marine.usgs.gov/fan_info.php?fan=2022-309-FA. The dataset, Seven_Mile_Island_2022_SBES_WGS84_UTM18N_xyz.zip provides single-beam bathymetry data points (x,y,z) referenced to World Geodetic System 1984 (WGS84) Universal Transverse Mercator (UTM) Zone 18 North (N) for the horizontal (x,y) and WGS84 ellipsoid height for the vertical (z). The datasets, Seven_Mile_Island_2022_SBES_NAD83_NAVD88_UTM18N_GEOID18_xyz.zip and Seven_Mile_Island_2022_SBES_NAD83_NAVD88_UTM18N_GEOID12B_xyz.zip provides single-beam bathymetry data points (xyz) referenced to North American Datum of 1983 (NAD83) UTM Zone 18N for the horizontal (x,y,z) and North American Vertical Datum of 1988 (NAVD88) orthometric height using GEOID18 and GEOID12B models, respectively, for the vertical (z). Supplemental_Information: For the single-beam bathymetry data, the differential positioning was obtained through post-processing the base station data to the rovers. The dataset was transformed from the initial WGS84 (G2139) UTM 18N datum to NAD83 UTM 18N NAVD88, using the GEOID18 model and the GEOID12B model (National Oceanic Atmospheric Administration [NOAA] and the National Geodetic Survey [NGS] VDatum software version 4.4.2 - http://vdatum.noaa.gov/).

This dataset is derived from a single field survey using identical equipment set-ups, and staff; therefore, the dataset is internally consistent. Methods were 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 antenna reference point (ARP) were measured using a geodimeter and accounted for during acquisition and (or) in post-processing. Differential Global Positioning System (DGPS) coordinates were obtained using the following post-processing software packages: NGS Online Positioning User Service (OPUS, https://geodesy.noaa.gov/OPUS/), and NovAtel’s Waypoint Product Group GrafNav, version 8.9). Due to an error in initial equipment set-up on the PWC, no data from the motion reference unit (heave, roll, pitch) were recorded for the first survey day 04-29-2022 (Day of Year [DOY]2022-119). This data was processed through the steps as normal, and thoroughly quality checked with the remainder of the survey data during the crossing evaluation. The crossing values were found to be acceptable and are included in this data release. Logical_Consistency_Report: These data were collected during a single field activity with consistent instrument calibrations. Completeness_Report: This data release contains single-beam bathymetry data points in the horizontal position and vertical elevation (x,y,z) from April/May 2022 collected off Seven Mile Island, New Jersey. Users are advised to read the complete metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The NGS horizontal published numbers for Permanent Identifier (PID) JU0450, stamping STONE HARBOR 1932, was retrieved from the NGS datasheet database and converted from NAD83 (2011) into WGS84 (G2139) UTM 18N using the Horizontal Time-Dependent Positioning (HTDP) online transformation utility version 3.5.0 (https://www.ngs.noaa.gov/TOOLS/Htdp/Htdp.shtml). The latest realization G2139 was introduced on 01/23/21. The survey acquisition dates succeed this date; therefore, it was the appropriate datum realization for post-processing the navigation data which was acquired in the WGS84 datum. The resultant base position used for post-processing was 39°02’21.66695 North (WGS84-G2139), 74°46’08.81537 West (WGS84-G2139), and -34.526 meters (m) ellipsoid height (WGS84-G2139). The base station erected on PID DP1533, stamping 5 T 2 2013, served as the secondary base station, but it was not used for post-processing. The kinematic trajectories (rover to base) were processed using NovAtel’s Waypoint GrafNav software version 8.9. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The ellipsoid height value -34.526 m (WGS84-G2139) was used in NovAtel’s Waypoint GrafNav software. Please refer to the Horizontal_Positional_Accuracy_Report segment for vertical position transformation into ellipsoid height. Lineage: Process_Step: Process_Description: GNSS Acquisition: Two Global Navigational Satellite Systems (GNSS) base stations were established on NGS benchmarks in which the roving vessels would be within 12-15 kilometers (km) of the base station at a given time. The primary benchmark JU04 (PID: JU0450) was located approximately in the middle of the survey extent where the secondary base station DP15 (PID: DP1533) was located to the northeast. The base stations were continually occupied and equipped with a Spectra Precision SP90M GNSS receiver recording full-carrier-phase positioning signals from satellites via Trimble Zephyr 3 Base GNSS antennas recording at a rate of 0.1 second (s).

The SLED collected 135.48 line-km (288 lines) and the WVR2 collected 145.46 line-km (60 lines). Boat motion was recorded at 50-millisecond (ms) using a SBG Ellipse A motion sensor. HYPACK A Xylem Brand (version 21.0.2.0), a marine surveying, positioning, and navigation software package, managed the planned-transect information and provided real-time navigation, steering, correction, data quality, and instrumentation-status to the boat operator. Depth soundings were recorded at 50-ms intervals using an Odom echotrac CV100 echosounder with a 4-degree, 200-kilohertz (kHz) transducer. Data from the GNSS receiver, motion sensor, and echosounder were recorded in real-time aboard all vessels 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 SonTek Castaway Conductivity, Temperature, and Depth (CTD) instruments. The instruments were periodically cast overboard to record changes in water column speed of sound (SOS). A total of 202 successful sound velocity casts were collected and ranged in depth from 0.15 to 3.26 m, and in sound velocity from 1490.30 to 1490.59 meters per second (m/s).

The resultant base position used for post-processing was 39°02’21.66695 North (WGS84-G2139), 74°46’08.81537 West (WGS84-G2139), and -34.526 meters (m) ellipsoid height (WGS84-G2139). The kinematic trajectories (rover to base) and base station coordinates were imported and processed using NovAtel’s Waypoint GrafNav software. Each kinematic GNSS data session from the survey vessel was post-processed to the concurrent base GNSS data session. Analyzing the data plots, trajectory maps, processing logs, satellite health plots, and other viewing utilities that GrafNav produces, provided measures to attain trajectory solutions (between the base and the rover) free of erroneous data that resulted in fixed positions. Some examples include 1) excluding satellites flagged by the program as having bad/poor health or cycle slips, 2) Excluding poor satellite time segments that have a negative influence toward a fixed solution, and 3) adjusting the satellite elevation mask angle 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 WGS84 (G2139) UTM 18N geodetic datum.

First, a vessel file *.vhf unique to the platform, was created that contains the surveyed offsets measurements between the sensors. A CARIS project was created using the *.vhf file, and then the HYPACK .RAW and the SPV profiles *.SVP were loaded. Next, the differentially corrected navigation files were imported using the generic data parser tool. Then, the differently corrected navigation files overwrote every non-differential position in the HYPACK .RAW file based upon time. The bathymetric data components (position, motion, depth, and SOS) were then georeferenced and geometrically corrected in CARIS to produce processed x,y,z positional data. Once georeferenced, the data were reviewed and edited for outliers, including further review in the Subset Editor utility for crossing status, and questionable areas or data points were removed. The geometrically corrected point data were then exported as an x,y,z ASCII text file referenced to WGS84 (G2139) UTM 18N.

The projection was set to WGS84 UTM 18N. The generated shapefile was visually scanned for any obvious outliers or problems. Next, a polyline shapefile (representing tracklines) was produced from the point shapefile using XTools Pro (version 22.0.4481) "Make Polylines from Points" geoprocessing tool for each survey platform (subFANs 22BIM03 and 22BIM05). Utilizing both the x,y,z (point) and trackline (polyline) shapefiles, a Python script was used to evaluate elevation differences at the intersection of crossing tracklines by calculating the elevation difference between points at each intersection using an inverse distance weighting equation with a search radius of 5 m. The root mean square (RMS) error for SLED (22BIM05), when crossing a trackline it previously surveyed, was 5.60 cm. The RMS error for WVR2 (22BIM03), when crossing a trackline it previously surveyed, was 4.65 cm. Once individual platform statistics were obtained, both datasets were merged into one file, and the crossing analysis yielded a 5.32 cm RMS error. These files were then exported from Esri ArcMap as x,y,z ASCII text (.txt) files using the XTools Pro "Table to Text" function. The resultant ASCII text file can be downloaded from this data release (Lyons and others, 2023) in Seven_Mile_Island_2022_SBES_WGS84_UTM18N_xyz.zip, and the trackline shapefile from Seven_Mile_Island_2022_SBES_WGS84_UTM18N_tracklines.zip.

The first transformation was from WGS84 (G2139) UTM 18N into NAD83 (horizontal) UTM 18N and NAVD88 (vertical) using GEOID18. The second transformation was from WGS84 (G2139) UTM 18N into NAD83 UTM 18N and NAVD88 using GEOID12B. VDatum reports a nationwide standard deviation of 2.0 centimeters (cm) for ellipsoid - NAD83 transformations, and a nationwide standard deviation of 5.0 cm for NAD83 to NAVD88 transformations in the coastal regions of the continental U.S. For more information about the positional accuracy for these datum transformations, visit the Estimation of Vertical Uncertainties VDatum webpage, https://vdatum.noaa.gov/docs/est_uncertainties.html.
