Santa_Rosa_Island_2021_SBES_xyz.zip is a xyz point file dataset of field activity number (FAN) 2021-322-FA single-beam bathymetry (SBB) data collected concurrently with subbottom data to provide a current seafloor elevation reference. The single beam bathymetry data were acquired in the World Geodetic System of 1984, realization G1762 (WGS84[G1762]) for the horizontal (x,y), and WGS84 ellipsoid for the vertical (z). This dataset was then post-processed to obtain Differential Global Positioning System (DGPS) coordinates. The final bathymetry dataset is referenced to WGS84(G1762) Universal Transverse Mercator (UTM) Zone 16 North (N) (x,y) and WGS84 ellipsoid height (z). This dataset was also converted into the North American Datum of 1983 (NAD83) (2011) UTM Zone 16N (x,y) and the North American Vertical Datum of 1988 (NAVD88) (z) with respect to GEOID 12A using using the National Oceanic and Atmospheric Administration’s (NOAA) VDatum version 4.3 transformation software (https://vdatum.noaa.gov/). Purpose: To provide georeferenced single-beam bathymetry data points that support subbottom stratigraphy identification, quantification, and interpretation. Supplemental_Information: Additional survey and data details are available from the USGS Coastal and Marine Geoscience Data System (CMGDS) at, https://cmgds.marine.usgs.gov/fan_info.php?fan=2021-322-FA and in the Field Activity Collection System (FACS) and geophysical logs, which are included in the download file, 2021-322-FA_logs.zip (Forde and others, 2022).

The placement of bathymetry survey equipment aboard the Sallenger is consistent per survey. Prior to the survey, the instruments are isolated, and positional offsets (x,y,z) measured to obtain internal offsets (reference between instrument) and external offsets (the vessel reference frame). All instruments are surveyed using a total station for accuracy, in millimeters (mm). During mobilization, equipment mounting points are verified for consistency and durability. Should any structural changes be made, then a new total station survey is performed prior to the cruise. All the measurements are recorded manually and entered digitally into the respective acquisition or processing program. This bathymetry dataset is internally consistent to this vessel and has not been independently verified. Logical_Consistency_Report: These datasets are post-processed single-beam bathymetric data points (XYZ) from USGS FAN 2021-322-FA with internal system measurements and calibrations. Completeness_Report: Approximately 219 line-kilometers (km; (35 tracklines) of single-beam bathymetry data was collected successfully, and produced 1,740,483 processed x,y,z data points. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The navigation for the single-beam bathymetry was collected using the Applanix POS MV Wave Master II. These files were then ported into POSPac Mobile Mapping Suite (MMS) version 8.6 and processed using the Post-Processed CenterPoint RTX (PP-RTX) module. The module allows centimeter (cm) level accuracy without establishing a local base station. The Santa Rosa Island, FL survey is located within the PP-RTX fast region convergence zone in which post-processing standards are reported to be 3 cm in the horizontal. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The navigation for the single-beam bathymetry was collected using the Applanix POS MV Wave Master II. These files were then ported into POSPac Mobile Mapping Suite (MMS) version 8.6 and processed using the Post-Processed CenterPoint RTX (PP-RTX) module. The module allows centimeter level accuracy without establishing a local base station. The Santa Rosa Island survey is located within the PP-RTX fast region convergence zone in which post-processing standards are reported to be 6 cm in the vertical. Lineage: Process_Step: Process_Description: Acquisition: A single-beam bathymetry survey was conducted in June 2021 aboard the R/V Sallenger, a 26-foot (ft) fiberglass research vessel outfitted with an ODOM CV100 echo sounder system with a 200 kilohertz (kHz) transducer for depth, an Applanix POS MV Wavemaster II V5 inertially aided navigation system (IANS) for timing, positioning, and attitude, and a Sontek CastAway Conductivity, Temperature, and Depth (CTD) sensor was used to measure sound velocity profiles. The ODOM echosounder and the Applanix Inertial Measurement Unit (IMU) were mounted in line vertically to a mounting pole on the starboard gunnel. The IMU was mounted above the sonar and was the center of reference point (0.00 mmeters [m]) for all the sensors used in this survey. When the pole was deployed, the instruments were approximately 1-m below the water surface. The topside part of the Applanix POS MV consisted of two Trimble GA830 Global Navigation Satellite System (GNSS) antennas that were affixed atop the cabin approximately amidships of the vessel, two meters apart, port-starboard (secondary antenna and primary antenna respectively for the R/V Sallenger) and all cables ran into their respective topside control boxes within the cabin. HYPACK version 2021.0.2 hydrographic acquisition and processing software managed incoming sensor data. All sensor data strings were referenced with a device identification code, time stamped to Coordinated Universal Time (UTC), and saved into a single raw (.RAW) data file. Sound velocity measurements were collected using Sontek Castaway CTD units to record changes in water column speed of sound (SOS). CTD profiles were collected based on time and space with inclusions for shallow water, deep water, offshore, inshore, and channel areas. Data were collected in WGS84 [G1762] Universal Transverse Mercator (UTM) Zone 16 North (N) coordinates and WGS84 ellipsoid height.

Raw position files from the POS MV were imported into POSPac and processed with the IN-Fusion PP-RTX processing mode utilizing Trimble CenterPoint RTX technology, creating smoothed best estimate of trajectory (.sbet) files and dynamic error files (.smrsmg) for each day of the survey. Data file recording was automated and preset to a maximum file size of 12 megabytes (MB) before opening a new file. File extensions for each survey day started with *.000 and incremented sequentially (*.001, *.002) until recording stopped. File naming convention was 2021_154_USB.000 where 2021 is the year, 154 is the Day of Year (DOY), USB is the digital media storage used, and .000 is file extension as previously described.

First, a vessel file specific to the R/V Sallenger equipment offsets and equipment specifications was created (*.vhf) in the "Vessel Editor" application. Next, the HYPACK acquisition files (.RAW), the post-processed navigation files (.sbet and . smrmsg), and the sound velocity profiles (.svp) were imported into CARIS. The bathymetric data components (position, motion, depth, and SOS) were geometrically corrected using the "Georeference Bathymetry Tool" to produce processed XYZ data. Additionally, during this process, the Global Positioning System (GPS) tide component (GPS tidal corrections utilize GPS height information from real time survey observations to obtain an ellipsoid height) was computed and were applied to the data. Next, a loosely defined moving average filter was applied line by line to reduce noisy and erroneous data points. A visual and statistical inspection of the data was further performed in the Subset Editor 2-Dimensional (D) and 3-D utility for crossing status agreements and any questionable areas. The dataset was exported as an XYZ American Standard Code for Information Interchange (ASCII) file using the CARIS HIPS and SIPS Data Export HIPS to ASCII function as WGS84 (G1762) UTM Zone 16N and ellipsoid height in meters.

One shapefile was created to display the data points, the second shapefile was created using the XTools Pro "Polylines from Points" ArcScript to display the tracklines. An Esri ArcMap add-in script using an inverse distance weighted equation was written locally, by a USGS staff member to evaluate the elevation differences at the intersection of crossing lines. The script uses the point and trackline shapefiles concurrently and produces another shapefile with the results. If discrepancies were found at a crossing, the source of the discrepancy was identified and, if needed, the line or segment of data points in error was statically adjusted, removed, or reprocessed. This crossing program was reiterated to produce a final numerical assessment of the crossing range for the SBB dataset. Results from 159 crossings report the minimum is 0.00 m, the maximum is 0.13 m, and a standard deviation of 0.02. Crossing values > 0.15 m = 0% and crossing values > 0.10 = 1%.
