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 mostly in depths > 2.0 meters.

The purpose of these data is to provide geographic locations of shot points so that features in the seismic profiles can be properly located along the tracklines. completed NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information pointOfContact NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information custodian notPlanned http://pubs.usgs.gov/of/2006/1381/GIS/thumbnails/ASV_SeismicShot500.jpg JPEG image of seismic shots on ASV lines.

The GPS antenna was mounted over the seismic system. Horizontal Positional Accuracy 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. Completeness Report Shot points are not available for sections of the survey lines where seismic data were not logged. Conceptual Consistency Data was compared to sediment grabs and was collected following standard best practices for recording sub-bottom profile data. Navigation was extracted from raw SEG-Y format and converted to ASCII text file. The file containing navigation for each shot was then queried to extract shots at 500 shot interval using the awk script makenav developed for USGS by Bill Danforth. The 500 shot file for each survey line was concatenated and imported to ArcGIS 9.1 then converted to a point feature class. 2007-05-20T00:00:00 Exported feature class from personal geodatabase to a shapefile and projected to geographic. 2007-07-01T00:00:00
