Title:
Cape Canaveral tracklines of geophysical data collected in 2016 by Coastal Carolina University
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:
Trackline files were recorded at the time of the survey using HYPACK, a marine surveying, positioning, and navigation software for data acquired by Coastal Carolina University (CCU).

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.

  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?
    The trackline position data were recorded using HYPACK hydrographic acquisition and processing software. All systems were navigated using Differential GPS. Horizontal accuracy is assumed to be 2 m.
  3. How accurate are the heights or depths?
    The survey tracklines do not include or represent vertical data.
  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 trackline file collected during a multibeam bathymetry survey.
