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 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 represent trackline navigation for swath bathymetry and sidescan-sonar data collected aboard the R/V Rafael during 2005 (05001), and 2006 (06001) in Apalachicola Bay and St. George Sound, Florida. The purpose of these data is to manage the filenames and geographic locations of data that was actually collected.

The GPS antenna was mounted over the bathymetric sonar and a layback of 4 meters was used for the sidescan-sonar data. Completeness_Report: Navigation tracklines for which there was no valid data were deleted. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: All systems were recorded using Real Time Kinematic GPS. The sidescan-sonar and seismic profiler were towed 4 meter behind the navigation antenna. Horizontal accuracy is assumed to be +/- 1 meter. Lineage: Process_Step: Process_Description: Navigation for swath bathymetry was extracted from raw sxr files and converted to ASCII text files for import to ArcGIS. Navigation for sidescan-sonar was extracted from raw xtf files and converted to ASCII text files for import to ArcGIS. The ASCII navigaton from both the bathymetry and sidescan were downsampled to one minute intervals. The one minute navigation points were then converted to a line using an ArcMap script Points_to_line v2 developed at the USGS by VeeAnn Cross Process_Date: 20070512 Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Brian Andrews Contact_Organization: U.S. Geological Survey Contact_Position: Geographer Contact_Address: Address_Type: mailing and physical address Address: 384 Woods Hole Rd.
