Description:

Abstract:

These data were collected under a cooperative mapping program between the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration Coastal Services Center (NOAA\CSC), and the Apalachicola National Estuarine Research Reserve (NERR). The primary objectives of this program were to collect marine geophysical data to develop a suite of seafloor maps to better define the extent of oyster habitats, the overall seafloor geology of the bay and provide updated information for management of this resource. In addition to their value for management of the bay's oyster resources, the maps also provide a geologic framework for scientific research and the public. High resolution bathymetry, backscatter intensity, and seismic profile data were collected over a 230 square kilometers of the floor of the bay. The study focused on the Apalachicola Bay and Western St. George Sound portions of the estuary mostly in depths > 2.0 meters.

Purpose:

These data are high-resolution acoustic backscatter measurements collected over Green Point and East Hole Bars in St. George Sound, Florida. These data were collected using the Autonomous Surface Vessel (ASV) IRIS primarily over known oyster bars in waters less than 1-2 meters deep.

Data_Quality_Information:

Logical_Consistency_Report: Information unavailable from original metadata.
Completeness_Report:

Although both the 100 kHz and 400 kHz frequency data were collected, only the high frequency 400 kHz data were processed and included in this mosaic. Small differences in contrast stretch (DN values) exist because of variations in sea and weather conditions on each survey day.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The ASV used RTK-GPS for navigation. RTK-GPS is assumed to be accurate within 1-2 meters. All GPS/DGPS data are referenced to WGS84. The sidescan-sonar transducers are mounted on a metal frame between the two pontoons about 0.5m below water surface directly below the GPS antenna.

Lineage:

Process_Step:

Process_Description:

The sidescan-sonar data were acquired with a EdgeTech 4200 FS dual-frequency sidescan-sonar system. The EdgeTech 4200 operates in a frequency range of 100 and 400 kHz. Data were collected and logged to onboard in .jsf format using EdgeTech JStar acquisition software. All jsf files for each Julian day were imported to Xsonar and converted to Xsonar format using the 400 kHz channel. Each file was corrected for slant range and beam pattern corrections as described in Danforth 1997. The individual line files were mosaiced in Xsonar with a range cutoff of 25m. The composite mosaic was exported as a GeoTIFF image, with an associated world file.

Process_Description:

Edits to the metadata were made to fix any errors that MP v 2.9.32 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Added an online link to the cross-reference. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.

Overview_Description:

Entity_and_Attribute_Overview:

There are no attributes associated with a GeoTIFF image. Image pixel values contain acoustic reflectivity values normalized to an 8-bit data range (0-255). Low-backscatter is represented by dark tones (low values) and high-backscatter is represented by bright tones (high values).
