Abstract:
During July 19 - 26 and November 17 - 18 of 1999, the U.S. Geological Survey (USGS), in cooperation with the Florida Geological Survey (FGS), conducted geophysical surveys of the Atlantic Ocean offshore of Florida's southeast coast from Orchid to Jupiter, FL and the Gulf of Mexico offshore of Venice, FL. This report serves as an archive of unprocessed digital boomer subbottom data, trackline maps, navigation files, GIS information, and formal FGDC metadata. Filtered and gained digital images of the seismic profiles are also provided. The archived trace data are in standard Society of Exploration Geophysicists (SEG) SEG Y revision 0 format (Barry and others, 1975) and may be downloaded and processed with commercial or public domain software such as Seismic Unix (SU). Example SU processing scripts and USGS software for viewing the SEG Y files (Zihlman, 1992) are also provided. These data are also available for viewing using GeoMapApp (<http://www.geomapapp.org/>) and Virtual Ocean (<http://www.virtualocean.org/>) multi-platform open source software. In addition to this DVD, the SEG Y files can also be downloaded from the USGS Coastal and Marine Geoscience Data System (<http://cmgds.marine.usgs.gov>).
Purpose:
The data archived here were collected under a cooperative agreement between the Florida Geological Survey and the USGS.
Supplemental_Information:
The USGS Saint Petersburg Coastal and Marine Science Center (SPCMSC) - St. Petersburg, FL, assigns a unique identifier to each cruise or field activity. For example, 99FGS01 and 99FGS02 tells us the data were collected in 1999 for the Florida Geological Survey (FGS) cooperative agreement and the data were collected during the first and second field activities for that project in that calendar year. Refer to <http://walrus.wr.usgs.gov/infobank/programs/html/definition/activity.html> for a detailed description of the method used to assign the cruise ID.The boomer subbottom processing system consists of an acoustic energy source that is made up of capacitors charged to a high voltage and discharged through a transducer in the water. The transducer is towed on a sled floating on the water surface and when discharged emits a short acoustic pulse, or shot, that propagates through the water column and shallow stratigraphy below. The acoustic energy is reflected at density boundaries (such as the seafloor or sediment layers beneath the seafloor), detected by the receiver (hydrophone streamer), and recorded by a PC-based seismic acquisition system. This process is repeated at timed intervals (for example, 0.5 s) and recorded for specific intervals of time (for example, 100 ms). In this way, a 2-D vertical image of the shallow geologic structure beneath the ship track is produced.An Applied Acoustic Engineering CSP 300 provided 300 Joules of energy per shot. Reflected energy was received by a Innovative Transducers, Inc. (ITI) ST-5 10-channel streamer and recorded by Triton Elics International, Inc. (TEI) Delph Seismic v. 1.36 acquisition software. The streamer contains 10 hydrophones evenly spaced every 0.60 m. The streamer was positioned directly behind the research vessel (parallel to the boomer sled), with a lateral separation of approximately 14 m (99FGS01) and 24 m (99FGS02). Refer to figure 2 included with this archive for a diagram of the acquisition geometries. The sample frequencies of the data were 240-2400 Hz and 8000 Hz, and record length was 100 ms. The shot spacing was highly variable; however, based on survey speeds of 3 knots and a shot rate of every 1 s, shot spacing was about 1.54 m.The unprocessed seismic data are stored in SEG Y rev. 0, integer, Motorola format, which is a standard digital format that can be read and manipulated by most seismic processing software packages (Barry and others, 1975). The SEG Y formatted trace files have a .TRA extension. The printable profiles provided here are GIF images that were filtered and gained using Seismic Unix software.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The validity or accuracy of marine subbottom profiles is highly qualitative and depends on equipment and operating condition variables. Visual inspection of the images rendered from the data did not show any major anomalies.
Logical_Consistency_Report:
This dataset is from one field activity with consistent instrument calibrations.
Completeness_Report:
These data are collected along tracklines (2-D) and are therefore inherently incomplete. Geologic details between lines must be inferred.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: folder.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Boomer data are relative to sea level. However, varying recorded static shifts of the data have been known to occur. Therefore, these data are not to be used for bathymetry.

Process_Step:
Process_Description:
Boomer processing: Using Seismic Unix software, the data were first converted to SU format (in doing so all the undefined header fields were zeroed) and then the SEG Y data were processed to produce GIF images of the seismic profiles included in this report. A representative boomer processing sequence consisted of (1) running a bandpass filter of 300-500-2500-3000 Hz, (2) applying automatic gain control, (3) displaying PostScript, and (4) converting of PostScript image to a GIF image.

Process_Description:
All concatenated, comma-delimited text files were imported into ArcGIS and saved as either a point or polyline file in the ESRI shapefile format.Trackline map creation: The trackline maps were created using ESRI ArcGIS 10 software. The processed navigation files, 99fgs01.txt and 99fgs01.txt, were imported into ArcMap 10 and processed using the Points to Lines ArcScript to create a line shapefile of the cruise tracklines (99fgs01_trkln and 99fgs02_trkln). The 500-shot-interval files s99fgs01.txt and s99fgs02.txt and the start of line files 99fgs01_s.txt and 99fgs02_s.txt were imported into ArcMap as point shapefiles 99fgs01_shots, 99fgs02_shots, 99fgs01_sol, and 99fgs02_sol. Please refer to the shapefile metadata included in the ArcGIS map document located under the Software section of this archive for additional details. The location maps were exported to Adobe Illustrator v. 14 for further editing then later converted into JPEG format by Adobe Dreamweaver v. 10 Build 4117. The map is unprojected (geographic coordinates, WGS84). The USGS is the originator of all layers used. Please see the ArcGIS readme file for detailed information about the GIS files used in this report.
