Title:
Cape Canaveral, Florida side scan sonar data collected in 2016 by Coastal Carolina University: Processed GeoTIFF Image
Abstract:
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.
Supplemental_Information:
Side scan sonar data for Cape Canaveral, Florida, was collected aboard the R/V Coastal Explorer by the Center for Marine & Wetland Studies (CMWS) between June 13 and 17, 2016. The instrument used for the side scan survey was a Klein 3900 Digital Side Scan Sonar dual frequency (445/900 khz) system. The system was rigged through the A-frame of the survey vessel. Prior to data collection, planned survey lines were created using the survey navigation and planning software HYPACK. The sonar system was interfaced with a Garmin 17x GPSmap 6212 Differential Global Positioning System (DGPS). CMWS post-processed the data and created final products. The CMWS at Coastal Carolina University created final products..

Why was the data set created?

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.

    Date: 19-Jul-2016 (process 1 of 3)
    Side scan sonar data for Cape Canaveral, Florida, were acquired using a Klein 3900 Digital Side Scan Sonar dual frequency (445/900 khz) system. The system was rigged through the A-frame of the survey vessel. Prior to data collection, planned survey lines were created using the survey navigation and planning software HYPACK.

    Date: 19-Jul-2016 (process 2 of 3)
    The side scan sonar data files (xtf) were processed with CARIS HIPS & SIPS ver. 9.1. The backscatter intensities were radiometrically corrected (including beam pattern correction and time varying gain adjustments) and the position of each acoustic sample was geometrically corrected for slant-range and georeferenced to the North American Datum of 1983 (NAD83) horizontal datum. The data were mosaicked into a 1-meter resolution image. Person who carried out this activity:

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    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.
  2. How accurate are the geographic locations?
    A Garmin 17X GPSmap 6212 was used during the survey.
  3. How accurate are the heights or depths?
    A Garmin 17X GPSmap 6212 was used during the survey.
  4. Where are the gaps in the data? What is missing?
    These are complete post-processed side scan sonar data collected near Cape Canaveral, Florida, in June 2016.
  5. How consistent are the relationships among the observations, including topology?
    This file represents the side scan sonar data collected during the survey.
