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.

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. The purpose of these data is to manage the filenames and geographic locations of seismic profile images that are hyperlinked to each trackline. 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/SeismicLines.jpg JPEG image of seismic tracklines JPEG EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > MARINE ECOSYSTEMS > BENTHIC EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > MARINE ECOSYSTEMS > COASTAL EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > MARINE ECOSYSTEMS > ESTUARY theme Global Change Master Directory (GCMD) Science Keywords 23.3 CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > FLORIDA OCEAN > ATLANTIC OCEAN > NORTH ATLANTIC OCEAN > GULF OF AMERICA place Global Change Master Directory (GCMD) Location Keywords 23.3 CMGP Coastal and Marine Geology Program Environmental Monitoring Marine Geology Seafloor Seismic Profile U.S. Geological Survey USGS WHSC Woods Hole Science Center field activity serial number 05001 field activity serial number 06001 navigation tracklines seismic navigation 2005 2006 Apalachicola Bay Apalachicola National Estuarine Research Reserve Florida Gulf of Mexico St. George Sound United States Subsurface theme General DOC/NOAA/NOS/OCM > Office of Coastal Management, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2026.

The GPS antenna was mounted over the bathymetric sonar and a layback of 4 meters was used for the seismics. 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 Sections of tracklines where seismic data were not logged were deleted Conceptual Consistency Data was compared to sediment grabs and was collected following standard best practices for recording sub-bottom profile data. 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 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 downsampled to a one minute interval, and then imported to ArcGIS using the AddXYdata tool in ArcMap (v. 9.2). The points then were converted to a line using an ArcMap script Points_to_Line v2 developed at the USGS by VeeAnn Cross. 2007-05-05T00:00:00 Exported feature class from personal geodatabase to a shapefile and projected to geographic. 2007-07-01T00:00:00
