This dataset, Madeira_Beach_2017_MBES_1m_xyz.zip, includes the processed elevation point data (x,y,z), as derived from a 1-meter (m) bathymetric grid. Purpose: The purpose of the survey was to collect high-density multibeam bathymetry data nearshore Madeira Beach, FL as part of a regional study designed to better understand coastal processes on barrier islands and sandy beaches. Data were collected during USGS Field Activity Number (FAN) 2017-305-FA, sub-FAN 17TST01. 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=2017-305-FA. Supplemental_Information: The processed sonar data are provided as American Standard Code for Information Interchange (ASCII) x,y,z point data files. These values are not the individual soundings, but nodes from a 1-m bathymetric grid. The Z value for the node is generated by utilizing a Combined Uncertainty and Bathymetry Estimator (CUBE) surface and has an estimated total value of uncertainty (Calder and Wells, 2007). The bathymetry data were collected and processed in the World Geodetic System of 1984 (WGS84) vertical and horizontal datums and were subsequently transformed using the National Oceanic and Atmospheric Administration's (NOAA) VDatum version 3.9 (v.3.9) transformation software (https://vdatum.noaa.gov/) horizontally to the North American Datum of 1983 (NAD83 [2011]) and vertically to the North American Vertical Datum of 1988 (NAVD88) relative to the GEOID model of 2012 B (GEOID12B).

Methods were employed to maintain data collection consistency aboard the platform. 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, then digitally entered into their respective programs.

Lineage: Process_Step: Process_Description: Acquisition: An ERS was conducted using two Teledyne Reson SeaBat T50-P multibeam echosounders, in dual-head configuration. The pair of Mills Cross (configuration) transmit and receive arrays, were placed side-by-side within a bracket that oriented them at opposing 30-degree angles (relative to horizontal). The bracket was pole-mounted on the starboard gunnel of the research vessel (R/V) Sallenger, a 26-foot fiberglass vessel. The sonar arrays were oriented athwartships (primary and secondary arrays facing outward and down to port and starboard, respectively) and located approximately 1-m below the waterline when deployed. An Applanix Pos MV Wavemaster II V5 inertially aided navigation system was used for timing, positioning, and attitude. The Inertial Measurement Unit (IMU) was mounted atop the sonar bracket just aft of the pole. Two Trimble GA830 Global Navigation Satellite System antennas were affixed atop the cabin approximately amidships of the vessel, two meters apart, port-starboard. An AML Oceanographic Micro-X sound velocity sensor was used for speed of sound readings at the sonar head. A Sontek CastAway CTD was used for measuring sound velocity profiles. Hydrographic survey acquisition and processing software, HYPACK/HYSWEEP (version 2016a) managed data inputs from sensors and produced two files (.RAW and .HSX). Data were collected in WGS84 [ITRF08] Universal Transverse Mercator (UTM) Zone 17 North (17N) coordinates.

Raw position files 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 (SMRMSG) for each day of the survey. Bathymetric data were post-processed in CARIS Hydrographic processing software HIPS/SIPS version 11.1.3. HYPACK acquisition files (HSX) were first imported into CARIS and then post-processed navigation files (SBET and SMRMSG) were imported and applied. Additionally, GPS tide (GPS tidal corrections utilize GPS height information from real time survey observations to obtain an ellipsoid height) was computed and sound velocity profiles were applied. Roll calibration was also performed, as necessary. TPU was calculated from real time values recorded in the HSX and the SMRMSG files. Data were filtered to exclude any points with RESON Quality flags of 0, 1, and 2 (these flags are assigned to individual soundings at the time of acquisition and are a metric of pass/fail in regards to both brightness and collinearity: 0 = fail both, 1 = pass brightness only, 2 = pass collinearity only), as well as soundings that had a TPU greater than stated IHO Special Order standards (IHO, 2008). Refraction artifacts were addressed using Refraction Editor. Further editing was performed in Subset Editor. A visual and statistical inspection of the data and resulting CUBE surface was performed to serve as quality control (Calder and Wells, 2007). A 1-m bathymetric CUBE surface was computed and the final surface was exported as an x,y,z ASCII file using the Base Surface to ASCII function.
