Abstract:
The U.S. Geological Survey (USGS) Coastal and Marine Geology Program has actively collected geophysical and sedimentological data in the northern Gulf of Mexico for several decades, including shallow subsurface data in the form of high-resolution seismic reflection profiles (HRSP). Prior to the mid-1990s most HRSP data were collected in analog format as paper rolls of continuous profiles up to 25 meters long. As part of the National Geological and Geophysical Data Preservation Program (NGGDPP; https://datapreservation.usgs.gov/), and in collaboration with the Bureau of Ocean Energy Management, Marine Minerals Program, scientists at the USGS St. Petersburg Coastal and Marine Science Center converted analog paper records to digital format using a large-format continuous scanner. The scanned image files were subsequently processed to fix distortions and crop out blank spaces prior to exporting as industry standard Society of Exploration Geophysicists date exchange (SEG-Y) formatted files. This data release serves as an archive of HRSP profiles annotated with header information, converted SEG-Y files, navigation data, and cruise trackline shapefiles. The HRSP data were collected using a Huntec boomer seismic system onboard research vessel (R/V) Kit Jones. The geophysical surveys were conducted from July 7-19, 1992 with data being acquired along the Florida shelf near Pensacola Beach, St. Joseph Bay aquatic Preserve, and St. George Island. Data collection and processing methods are described in USGS Data Series 1047.
Purpose:
To archive all digitized analog boomer seismic profile data and associated files collected along the northern Gulf of Mexico from the R/V Kit Jones cruise, July 7 to 19, 1992.
Supplemental_Information:
The USGS Saint Petersburg Coastal and Marine Science Center (SPCMSC) currently holds data from 13 major geophysical surveys from the northern Gulf of Mexico in its paper repository. A conservative estimate of 2,000 line-kilometers (km) of data are available. Paper copies of data are difficult and expensive to duplicate and share with other facilities and cannot be analyzed using standard GIS and interpretative software. Conversion of this data into a usable digital format is necessary to archive the geologic information that otherwise might be lost, requiring additional redundant and expensive marine geophysical surveys. The USGS NGGDPP addresses the need to preserve, catalog, and provide access to geological and geophysical data for scientific research and economic development. In addition to the current efforts under the NGGDPP, four geophysical investigations from the 1980s and 1990s were previously archived through a preservation project in collaboration with the Bureau of Ocean Energy Management (Harrison and others, 2007; Sanford and others, 2009a, b, c). Data collection and processing methods are described in detail in Bosse and others (2017). The USGS SPCMSC scans its analog HRSP holdings using a large-format continuous scanner. The analog to digital conversion process used for this dataset is similar to the processes used previously in Harrison and others (2007) and Sanford and others (2009a, b, c). The digital files were converted into Tagged Image File Format (TIFF) for standard accessibility by raster image processors. The TIFF images of the seismic profiles were then converted into SEG-Y format. This standard non-proprietary format is the accepted industry standard for seismic data and can be accessed by all major seismic data processing and interpretation systems. Navigation and metadata files, which are generated for use in GIS, database, and Internet Message Access Protocol (IMAP) services as well as processed seismic profile images are also provided. The processed profiles provided in this data release are Portable Document Format (PDF) files that were created using Seismic Unix and/or Imagemagick software. The northern Gulf of Mexico is a passive continental margin, where minimal structural change to the shallow stratigraphy has occurred during the last few thousand years (Anderson and others, 2004). Therefore, subsurface data collected from this environment for the purposes of geologic assessment can be considered useful in perpetuity. The geologic information collected by the USGS in the northern Gulf of Mexico remains a valuable resource for seafloor and stratigraphic investigations and is continuously revisited by researchers interested in Holocene and recent earth processes. For example, decades-old geologic data is commonly used in sediment resource studies in coastal Louisiana (for example, Kindinger and others, 2001; Kulp and others, 2002; Rogers and others, 2009) and previously collected datasets across the Mississippi-Alabama shelf have been used in recent geologic-framework assessments (Roberts and others, 2004; Greene and others, 2007; Flocks and others, 2011). The seismic data were collected using a single-channel Huntec boomer/benthos hydrophone system with an Ocean Research Equipment (ORE) Geopulse power supply. The system consists of an electromechanical sound source mounted on a catamaran sled towed behind the vessel at the water surface. The signal emitted from the sound source is received by a 5 meter- (m) long hydrophone streamer towed alongside the sled. The received signal was recorded by a signal that passed through bandpass filters and was sent to a graphic recorder using a sweeping stylus to burn electrostatic paper. The seismic returns were printed onto paper rolls as two-dimensional profiles representing shots horizontally (time along track) and depth (two-way travel time). Geographic positioning of the system was collected using a long-range navigation (LORAN-C) system and annotated onto the paper copies.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The validity or accuracy of boomer profiling data 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:
These data were acquired during a single survey with consistent instrument calibrations
Completeness_Report:
This dataset is considered complete for the information presented. Most analog seismic profiles collected during the original survey were successfully scanned and converted to digital format with the exception of a variety of lines missing from the analog archives. The seismic profiles provide a two-dimensional (2D) representation of the subsurface along the acquisition tracklines. Users are advised to read the rest of the metadata record carefully for additional details. Instances where there are multiple SEG-Y or Profile With Scales files associated with a single Profile with Header tiff are due to sweep changes along that particular line or tiff files being too large.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
As the seismic reflection data were acquired, the position of the vessel was recorded using a LORAN-C system. The accuracy of LORAN-C varied from 528 to 1,320 feet (ft), with repeatable accuracy between 60 and 300 ft. Positions were recorded in latitude and longitude coordinates at irregular intervals and appear on the seismic profiles as incremental, hand-annotated vertical event marks. Navigation data were obtained as .dat files and saved as tab-delimitated text files.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
These data are not to be used for bathymetry. Two-way travel (TWT) times shown on the printable profile images are relative to local sea level at the time of data acquisition.

Process_Description:
Raw Data Scanning - The seismic data collected during each survey is currently located in the SPCMSC archives and arranged in cruise-specific storage boxes. The analog boomer data is in the form of 50 centimeter (cm)-wide paper rolls, paper fan-folds, and vellum rolls. The various rolls can be up to 20 m long and contain multiple seismic tracklines. The rolls contain the seismic profile image with pertinent collection characteristics annotated during acquisition, such as shot number and time and may also include environmental conditions and equipment details. Horizontal lines across the profiles represent two-way travel time in milliseconds (ms), and vertical lines represent navigation fixes acquired and annotated as the survey was underway. The raw data were scanned on a Contex SD 3600 continuous-feed scanner. Using the NEXTimage 4 program (Contex), the scans were saved as 8-bit grey-scale TIFF files at 300 dots-per-inch (dpi) resolution. To minimize the final image file size for archiving, a batch conversion program was used to reduce the resolution to 210 dpi. For mapping purposes, the raw navigation data were imported into Esri ArcGIS (version 10.3) as point data, converted to lines using the make polylines from points tool from the XTools Pro (version 12.2 [build 2197]) toolbar.

Process_Description:
Cropping - The scanned TIFF images were imported into Adobe Photoshop (Ps) Creative Cloud 2017 and blank edge areas were cropped out to further reduce file size. For rolls that included more than one line of seismic data, the file was separated into individual lines. Separation was completed by cropping everything except for the line of interest, determined by the raw navigation information, from the original scan and saving it as a new file with its associated line name. The file naming convention is as follows: CruiseID-DataAssociation_trackline#.tif (for example, KJ92-1-SEGY_4.tif). It includes the cruise identification (KJ92-1), data association(PWH [profiles with headers] or SEGY), and trackline number (which may include a subsection letter after the line number for tracklines that were recorded on multiple rolls).

Process_Description:
Correcting scan distortion - Distortion correction is necessary because it is difficult to ensure vellum rolls are fed into the scanner straight; distortion correction is performed by placing a line over the 0 ms line (water level) on the scan. It is important that horizontal lines are perpendicular to the vertical lines on the scans or the image to SEG-Y conversion will not be accurate. Distortion was corrected using the Rectangular Marquee Tool in Adobe Photoshop to select and create a new layer of the distorted area of the scan. A skewed transform was performed, and the corrected images were saved into a new folder without layers (flattened) to reduce file size.

Process_Description:
Image to SEG-Y - The scanned, distortion-corrected images were converted to digital SEG-Y (.seg) format (revision 0) (Barry and others, 1975) using the proprietary software ImageToSEGY 2.2 (Chesapeake Technology). The scanned images were opened in ImageToSEGY and the export area was defined by assigning values to the top, bottom, left, and right pixel locations using the imaged water surface (0 ms), maximum two-way travel time (for example 112.5 ms) and raw navigation data for each line. Trace amplitudes in the scanned profiles are represented by pixels, so each pixel becomes a trace sample and the sample rate of the converted SEG-Y version is the record length divided by the number of vertical pixels in the profile. For example, if the profile is 4,435 pixels vertically and the two-way travel time is 112.5 ms, then the sample rate for the SEG-Y file version is 0.000025 s.
