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 https://cmgds.marine.usgs.gov/fan_info.php?fan=2010-012-FA or the St. Petersburg Coastal and Marine Geology InfoBank https://walrus.wr.usgs.gov/infobank/m/m210gm/html/m-2-10-gm.meta.html.

Purpose:

This dataset contains trackline navigation for approximately 492 km of EdgeTech SB-512i chirp seismic-reflection data collected by the U.S. Geological Survey - St. Petersburg 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:

Only the portions of this seismic-reflection survey that lie in the western survey area (west of Petit Bois Island, MS) are included in this shapefile. Additional seismic-data acquired east of this study area will be included in a future report. Sections of tracklines where navigation was recorded but no seismic data were logged are not included. 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 towed astern of the R/V Tommy Munro approximately 3 m below the surface. Differential Global Positioning System (DGPS) navigation coordinates were obtained from the Coda Octopus F190 motion reference unit (equipped with Omnistar HP) antenna and EdgeTech Discover acquisition software logged the navigation coordinates in arc-seconds to individual trace headers in the Society of Exploration Geophysicists Y (SEG-Y), revision 1 format (Norris and Faichney, 2002). Horizontal offsets between the navigation antenna and the towfish were not accounted for during acquisition, nor was the vertical draft of the towfish beneath the sea-surface. Navigational uncertainty is increased due to fish motion behind the vessel, which is caused by sea state and vessel speed induced changes in the angle and scope of the tow cable. Resulting positional accuracy is assumed to be better than + or - 10 m.

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). EdgeTech Discover acquisition software 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 towed astern of the vessel approximately 3 m below the water surface. Differential Global Positioning System (DGPS) navigation coordinates were obtained from the Coda Octopus F190 motion reference unit (equipped with Omnistar HP) antenna 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 492 km of seismic data from this survey are included in this shapefile.

Process_Step:

Process_Description:

An executable C-shell script called on SIOSEIS (version 10.2.25) to: 1) read the SEG-Y data processed by Arnell (Harrison) Forde of the St. Petersburg Coastal and Marine Science Center 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_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 ('stpete_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\10cct02\') by replacing the '10i' preceding each image name with 'pathname' + the preceding characters.

Process_Step:

Process_Description:

Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Attempted to modify http to https where appropriate. Added a landing page link as the first link in the identification section. Updated the link to the field activity. The source information was incomplete and had to be modified to meet the standard. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. Fixed link to browse graphic. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
