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 in mostly in depths > 2.0 meters.
Purpose:
These data are high-resolution acoustic backscatter measurements of the bottom of Apalachicola Bay Florida. This raster covers approximately 141 square kilometers of portions of Apalachicola Bay.

Data_Quality_Information:
Logical_Consistency_Report: Information unavailable from original metadata.
Completeness_Report:
Although both the 100 kHz and 500 kHz frequency data were collected, only the low frequency 100 kHz data 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:
RTK-GPS is assumed to be accurate within 1-2 meters. Standard GPS is assumed accurate within 5-10 meters. 99% of the positional data are DGPS. Unless noted, all GPS/DGPS data are referenced to WGS84 (NAD83). The sidescan-sonar towfish was towed from an outrigger on the starboard side of the survey vessel in 2005 and the port side in 2006 such that the sonar was about 1-m below the surface and even with the stern of the survey vessel.

Process_Step:
Process_Description:
The sidescan-sonar data were acquired with a Klein 3000 dual-frequency sidescan-sonar systems. The Klein 3000 operates in a frequency range of 100 - 120 kHz. All sidescan-sonar data were logged digitally at a sample rate resulting in a 0.18-m pixel size in the across-track direction and approximately 0.14-m in the along-track direction . A median filtering routine was applied to the sidescan-sonar data to remove speckle noise, resulting in a 0.73-m pixel size. The data for each survey were further processed and digitally mosaiced using PCI Geomatics Software and procedures described in Danforth (1997), and Paskevich (1992) resulting in an enhanced, geographically correct, sidescan-sonar mosaic with 1 meter pixel resolution. The composite mosaic was exported as a TIFF image, with an associated world file.

Process_Step:
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.). The link to the data in the Identification_Information section had to be fixed. Add online links to the cross-references. 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.
