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 are to collect marine geophysical data and develop a suite of seafloor maps to better define the extent of oyster habitats and the overall seafloor geology of the bay to 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 76 square kilometer area covering the deeper (>2.0 m) portions of St. George Sound to characterize the surface and subsurface of Apalachicola Bay and St. George Sound for geologic framework investigations.
Purpose:
These data are high-resolution bathymetric soundings of the bottom of St George Sound Florida. This GeoTIFF covers approximately 76 square kilometer of portions of St. George Sound between 0m -10.4m deep.

Data_Quality_Information:
Logical_Consistency_Report:
These data have not been quantitatively compared to previous hydrographic data, although they generally agree with qualitative comparison of published NOAA charts.
Completeness_Report:
Bathymetric cross lines were collected and used for accuracy assessment but they were not included in the final grids.
Lineage:
Process_Step:
Process_Description:
Bathymetric data were corrected for variations in the speed of sound throughout the water column; sound velocity profiles were acquired throughout the survey area using an Applied MicroSystems SVPlus Sound Velocimeter. These data were downloaded and reformatted to the required format needed for use within University of New Brunswick's Ocean Mapping Group (OMG) SwathEd multibeam processing software. The raw Submetrix 2000 Series data were "unraveled" and reformatted into the OMG format. This process creates several files on disk:
1) bathymetric soundings 2) raw sidescan backscatter 3) navigation 4) parameter files describing the configuration of the system (i.e. offsets between motion reference unit and GPS antenna, etc). This process also incorporates the sound velocity profiles in order to properly trace the rays given the structure of the water column.

Process_Step:
Process_Description:
The OMG formatted bathymetric data were then graphically edited using the SwathEd multibeam processing software. This enabled editing on a "ping-by-ping" basis, both in the across- and along-track dimension. Spurious or erroneous data were removed. The navigation data were also graphically examined for each line of data.

Process_Description:
Soundings were corrected to mean lower low water (MLLW) using high-resolution Real-Time Kinematic Global Positioning System (RTKGPS) measurements. The one second RTK data were smoothed in MatLab using a 3rd order polynomial and then merged with each line file in SwathEd.

Process_Step:
Process_Description:
Soundings data were gridded using the weigh_grid routines from Swathed. Soundings were corrected to mean lower low water during the weigh_grid operation using the real time kinematic differential Global positioning navigation files.
The final weigh_grid parameters used were: weigh_grid -omg -coeffs -butter -lambda 5 -cutoff 20
Max_incidence angle was not used in most lines to use the entire swath. Only lines from rough days or big heave were gridded with a small incidence angle to maximize the good data from adjacent lanes and reduce the noisy data.
