Title:
Cape Canaveral, Florida, multibeam bathymetry collected in 2016 by Coastal Carolina University: Processed elevation point data (XYZ)
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:
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.

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.

    Bathymetric data were post-processed using CARIS HIPS version 9.1 hydrographic system software. Soundings (x,y,z) were corrected for vessel motion using a Kongsberg Seatex Motion Reference Unit (MRU), variations in water column sound velocity using Applied Microsystems smartSVP data, and adjusted for variations in water height (tides) using the water level data from Trident Pier tide station (ID 8721604). Post-survey data cleaning and final surface model creation were applied by CMWS. Soundings (xyz) were exported from a CARIS BASE Surface as an x,y,z text file with 1-meter spatial resolution. Final x,y,z soundings, surface models, and derived products are relative to the North American Datum (NAD83) horizontal datum and North American Vertical Datum of 1988 (NAVD88) (GEOID12A) vertical datum.

  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 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 version 2014 hydrographic acquisition and processing software.
  3. How accurate are the heights or depths?
    Please see Horizontal Position Accuracy Report above
  4. Where are the gaps in the data? What is missing?
    These are complete post-processed x,y,z bathymetric data points from acoustic multibeam data collected near Cape Canaveral, Florida, in June 2016.
  5. How consistent are the relationships among the observations, including topology?
    This file represents the post-processed bathymetric data (x,y,z) collected during a multibeam bathymetry survey.
