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 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 shot navigation at 500 shot intervals for seismic profile data collected during USGS field activities 05001, and 06001 in Apalachicola Bay and the western part of St. George Sound, Florida. These data are used to locate the 500 shot index markers on each seismic profile in geographic space.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
RTK GPS was used to navigate the survey platform from which the seismic-reflection data were collected. The GPS antenna was mounted over the bathymetric sonar and a layback of 4 meters was used for the seismic systems.
Completeness_Report:
Navigation tracklines for which there was no valid data were deleted.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Navigation was recorded to all data acquisition systems using Real Time Kinematic GPS at a one second interval.
Horizontal accuracy of the navigation is assumed to be +/- 1 meter. The shot point file and survey line file for the
seismic data are both derived from the same navigation file that was logged by the seismic acquisition system, but
because the two were processed differently, the shot points do not always fall directly on the survey line. To create
the shot point file, the navigation was queried to extract every 500th point starting with shot point 500. By
contrast, to create the survey line file, the navigation was queried at a one minute interval (every 60th point), and
then a line was drawn using these points. Because of the different processing approaches, many of the shot points,
although close, do not fall exactly on the survey line. If meter accuracy is truely needed, it would be best to
extract the navigation from the archived SEG-Y seismic files.
Lineage:
Process_Step:
Process_Description:
The seismic data that were collected from the R/V RAFAEL were acquired differently in 2005 than in 2006. During the first seven survey days of the 2005 field season (Julian days 076-083) a Knudsen 320 b chirp profiler (3.5-12 kHz) was used and during the remaining part of the 2005 season a towed Edgetech FSSB 424 (2-24 kHz) system was used. In 2006, the Edgetech FSSB 424 was used for the entire field season, but it was mounted on a pole rather than being towed on a cable. In 2005 both the Knudsen and Edgetech seismic data were logged in SEG-Y format using Delph Seismic +. In 2006 the Edgetech seismic data were logged in SEG-Y format using SBLogger. Navigation was extracted from the raw SEG-Y format seismic data and converted to an ASCII text file. The ASCII navigation file was then queried to extract every 500th shot and exported as an ASCII text file. This file was imported to ArcGIS 9.1 and converted to a point feature class.
