Description:

Abstract:: In 2010, the U.S. Geological Survey in Woods Hole, MA and St. Petersburg, FL, in partnership with the U.S. Army Corps of Engineers, Mobile District conducted geologic mapping to characterize the seafloor and shallow subsurface stratigraphy offshore of the Gulf Islands of Mississippi. The mapping was carried out during two cruises in March, 2010 on the R/V Tommy Munro of Biloxi, MS. Data were acquired with the following equipment: an SEA Ltd SwathPlus interferometric sonar (both 234 kHz and 468 kHz systems), a Klein 3000 and a Klein 3900 dual frequency sidescan-sonar, and an Edgetech 512i chirp subbottom profiling system. The long-term goal of this mapping effort is to produce high-quality, high-resolution geologic maps and geophysical interpretations that can be utilized to identify sand resources within the region and better understand the Holocene evolution and anticipate future changes in this coastal system. More information on the field work can be accessed from the Woods Hole Coastal and Marine Science Center Field Activity webpage <http://quashnet.er.usgs.gov/data/2010/10012/> or the St. Petersburg Coastal and Marine Geology InfoBank <http://walrus.wr.usgs.gov/infobank/m/m210gm/html/m-2-10-gm.meta.html>.
Purpose:: This dataset contains trackline navigation for approximately 1523 km of EdgeTech SB-512i chirp seismic-reflection data collected by the U.S. Geological Survey - Woods Hole Coastal and Marine Science Center in 2010. The seismic-reflection data are used to define sub-surface stratigraphy offshore of the Gulf Islands in Mississippi, and these navigation data can help spatially correlate the seismic-reflection profiles with other data in the GIS.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report: All attributes were checked in a consistent manner.

Logical_Consistency_Report:

Any spurious data points were removed during processing. For each seismic trackline there is one seismic-profile image that is hyperlinked by the field 'ImageName'. No duplicates exist.

Completeness_Report:

Sections of tracklines where navigation was recorded but no seismic data were logged are not included.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: The SB-512i was mounted on a catamaran and towed at the sea surface approximately 50 m astern of the R/V Tommy Munro. Position data were provided by a Differential Global Positioning System (DGPS) navigation receiver mounted on the catamaran, and data were transmitted to the acquisition computer on the vessel via a 2.4 GHz radio link. The SonarWiz.MAP +SBP acquisition software logged the navigation coordinates (in arc-seconds) to individual trace headers. Positional accuracy is assumed to be better than 10 m.

Data were not collected on 20100310, and 20100312-20100314 due to weather conditions, crew changes, or survey location.

Source_Contribution:

High-resolution chirp seismic-reflection profiles were collected using an EdgeTech Geo-Star Full Spectrum Sub-bottom (FSSB) system and SB-512i towfish (0.5-12 kHz) (EdgeTech, 2008). SonarWiz.MAP +SBP acquisition software (Chesapeake Technology Inc., 2009) was used to control the Geo-Star topside unit and digitally log trace data in the Society of Exploration Geophysicists Y (SEG-Y), revision 1, standard format (Norris and Faichney, 2002). The SB-512i towfish was mounted on a catamaran and towed astern of the starboard side of the vessel. Navigation coordinates (in arc-seconds) were obtained from a DGPS antenna mounted on the catamaran and logged to the SEG-Y trace headers. Data were acquired using a 0.5 to 8 kHz frequency sweep, a 5 millisecond pulse length, a 0.25 second shot rate, a 46 microsecond sample interval, and a 100 millisecond record length. A total of 1523 km of seismic data were collected.

Process_Step:

Process_Description:

An executable C-shell script called on SIOSEIS (version 10.2.25) to: 1) read the raw SEG-Y data and create shot gathers containing two consecutive traces; 2) create a stacked trace from the two trace gathers while maintaining the navigation coordinates from the header of the first trace in each; and 3) write the stacked traces to new SEG-Y files. This stacking flow ensured that the resulting traces were spaced greater than 0.5 m apart along the trackline, which is a prerequisite for the traces to be loaded into GeoGraphix SeisVision (version R5000) for digital interpretation.

Process_Step:

Process_Description:

An executable C-shell script called on Seismic Unix (version 4.1) to read the stacked SEG-Y files, write a Seismic Unix file, and extract SEG-Y trace header information, including shot number, longitude, latitude, year, Julian day, and time of day (UTC) to ASCII text files for each survey line. The data were filtered using AWK (no version) to save records for the first and last shots, and shots at unique longitude/latitude positions in between. Geographic coordinates (WGS84) were converted to UTM zone 16 coordinates (WGS84) using Proj (version 4.6.0), and added to the text files in two new columns.

Process_Step:

Process_Description:

The shapefile created in the previous step was used as an input for VACExtras (version 1.97), a VB collection of tools developed by VeeAnn Cross (USGS-WHCMSC), which converts point data to a new polyline shapefile ('WHCMSC_SeismicTrackline.shp'), based on record order. The 'FileName' field was used to define which points were used to generate each polyline feature. Using XTools Pro (version 5.2.0) for ArcGIS desktop, the length of each polyline segment was calculated and included in the attribute field 'Length', specifying UTM, Zone 16, WGS84, and kilometers. The "find and replace" option in the ArcMap attribute table viewer was used to modify the 'ImageName' attribute to correctly reflect the relative path of the directory containing the seismic-reflection profile portable network graphic (PNG) images ('GIS_catalog\Seisimage\2010-012-FA\') by replacing the 'l', 'transit', or 'tieline' preceeding each image name with 'pathname' + the preceding characters.
