The transects were spaced 500 meters (m) apart in the alongshore direction and each was approximately five kilometers (km) long in the cross-shore. Purpose: To update bathymetry for a bathymetric change analysis and a numerical wave modeling effort. Data were collected during USGS field activity number (FAN) 10CBS01 and was supported by funding from NASA's Kennedy Space Center under agreement NNK09CB7I; additional survey details are available at http://cmgds.marine.usgs.gov/fan_info.php?fan=10CBS01.

Data_Quality_Information: Logical_Consistency_Report: These bathymetry data represent the surveyed lines during acquisition of single-beam bathymetry data collected at Cape Canaveral, Florida in July 2010. Completeness_Report: This is a complete processed point file (XYZ format) for the single-beam bathymetry survey. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The root mean square error for the base station used for processing the single-beam bathymetry was less than five centimeters (cm). Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Crossing errors were computed by comparing points located within 1 m of each other and separated by at least ten minutes (1579 crossings). Differences were randomly distributed over the survey area and showed no depth dependence. Mean difference was 12 cm, with a minimum difference of less than 1 cm and a maximum difference of 42 cm. Lineage: Process_Step: Process_Description: GPS acquisition: A GPS base station was erected within 20 km of the survey area on a pre-existing National Geodetic Survey (NGS) benchmark ("WARD") at Cape Canaveral, Fla. GPS data at the base station were recorded using an Ashtech Z-Xtreme GPS receiver that recorded the 12-channel full-carrier-phase positioning signals (L1/L2) from the satellites via the Dorne/Margolin choke-ring antenna. GPS data on the boat (rover), a 21 foot Predator, were also recorded with an Ashtech Z-Xtreme GPS receiver but with an Ashtech geodetic survey antenna. Both the base and rover recorded positions at one Hertz (Hz). Process_Date: 20100729 Process_Step: Process_Description: GPS processing: All static base station sessions were run through On-Line Positioning User Service (OPUS) maintained by the National Oceanic and Atmospheric Administration (NOAA) and the National Geodetic Survey (NGS). The base location results from OPUS were put in a spreadsheet to compute final values and error analysis. Using the OPUS values for each day and the total time that data were collected each day, the average weighted values were calculated for each day for latitude and longitude (so the longer occupation times held more value than the shorter times). The final value for latitude and longitude was used in GrafNav for the base station value. Error was calculated using UTM output from OPUS (to get error in meters) for each day and was calculated as the absolute value of the final value minus the daily value.

The Lowrance recorded the data on a 4-gigabyte (GB) SD card at 10 Hz. Process_Date: 20100729 Process_Step: Process_Description: Merging of GPS and soundings: Merging of the GPS and sounding data was done using the MathWorks MATLAB (R2015a) computing environment, to run scripts developed by USGS scientists at the St. Petersburg Coastal and Marine Science Center. First, soundings were converted from feet to meters and then GPS data were interpolated to 10 Hz. The time offset between the GPS altitude and soundings was computed using a cross-correlation with a 10 Hz resolution. Elevation of the seafloor was then computed as, z=altitude-R-depth, where R was the vertical offset between the GPS antenna and the transducer (2.30 m). Waves were removed by applying a 16-second wide Hanning convolution filter to the seafloor elevation time series.
