A geophysical survey was conducted offshore Cape Canaveral, Florida by Coastal Carolina University offshore of Cape Canaveral, Florida using high-resolution chirp sub-bottom, multibeam bathymetry and side scan sonar (SSS) systems on June 13, 14, 16, and 17 of 2016. This USGS data release includes the resulting processed elevation point data (xyz), an interpolated digital elevation model (DEM), with processed backscatter, side scan sonar, and seismic chirp data.
The purpose of the survey was to collect geophysical data in the shallow water (2-20 meters [m] water depth) off of Cape Canaveral, Florida, to better understand the linkages between geologic variability and the evolution and resiliency of the coastal system. Data were collected during USGS field activity number (FAN) 2016-342-FA. Additional survey and data details are available from the USGS Coastal and Marine Geoscience Data System (CMGDS) at, http://cmgds.marine.usgs.gov/fan_info.php?fan=2016-342-FA.
Multibeam and backscatter data for Cape Canaveral, Florida, were acquired using a Kongsberg EM3002D dual-head multibeam sonar system aboard the research vessel (R/V) Coastal Explorer by the Center for Marine and Wetland Studies (CMWS) at CCU, South Carolina. A Kongsberg Seatex Seapath system was used to provide position and attitude data during data collection and accounted for vessel motion such as heave, pitch, and roll (x and y position accuracy ± 1 centimeter (cm), z position accuracy 2 cm, heading accuracy 0.05%, roll and pitch accuracy ± 0.03°, heave accuracy ± 5% or 5 cm). Prior to data collection, planned survey lines were created using the survey navigation and planning software HYPACK, version 2014. Altitude data were used to account for tide cycle fluctuations and sound velocity profiles were collected with an Applied Microsystems smart SV. The CMWS at Coastal Carolina University created final products from the post-processed multibeam bathymetry data.

The accuracy of the data was determined during data collection. This dataset was from one research cruise and was therefore internally consistent. 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 and digitally entered into their respective programs. The data have not been independently verified for accuracy.
This file represents the post-processed backscatter data (x,y,z) collected during a multibeam bathymetry survey.
These are complete post-processed backscatter data from acoustic multibeam data collected near Cape Canaveral, Florida, in June 2016.
A Kongsberg Seatex Seapath system was used to provide position and attitude data during data collection and accounted for vessel motion such as heave, pitch, and roll (x and y position accuracy ± 1 cm, z position accuracy 2 cm, heading accuracy 0.05%, roll and pitch accuracy ± 0.03°, heave accuracy ± 5% or 5 cm). The trackline position data were recorded using HYPACK hydrographic acquisition and processing software.

Processing and mosaicking of Kongsberg EM3002D data were completed using Geocoder engine within Fledermaus FMGTv7.5. Within FMGT, the backscatter intensities were radiometrically corrected (including despeckling, Time Varying Gain (TVG) corrections, and Angle Varying Gain (AVG) adjustments) and the position of each acoustic sample was geometrically corrected for slant-range and georeferenced. The mosaic was exported from FMGT in GeoTIFF format. Final mosaics are relative to the North American Datum (NAD83) horizontal datum.
