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 shot point navigation at even 500 shot intervals 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.

Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The SB-0512i was mounted on a catamaran sled 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 in the Society of Exploration Geophysicists Y (SEG-Y), Revision 1 format (Norris and Faichney, 2002). Positional accuracy is assumed to be better than 10 m.

Source_Citation_Abbreviation: Information unavailable from original metadata 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 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.

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 ( .csv version of the unique shot point navigation is included in the WinZip file '2010-012-FA_shots.zip'. 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.

A 500 shot interval was chosen because it corresponds to the annotation interval provided along the top of the seismic-reflection profile portable network graphic (PNG) images, which are included in the 'GIS_catalog\Seisimage\2010-012-FA' directory.

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.). Fixed a one of the links to the data in the Distribution_Information section. 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. Added a distribution format to account for the CSV file in the zip file. 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.
