This mapping program was part of a larger research effort supporting the Office of Naval Research (ONR) Ripples Directed-Research Initiative (DRI) studies at MVCO by providing data collection and modeling. The geophysical data will be used to provide initial conditions for wave and circulation models for the study area. Ultimately, geophysical mapping, oceanographic measurements and modeling will help to improve our understanding of coastal sediment-transport processes. The geophysical mapping utilized a suite of high-resolution instrumentation to map the surficial sediment distribution, depth and sub-surface geology: dual-frequency 100/500 KHz sidescan-sonar system, 234-KHz interferometric sonar, and 500 Hz -12 KHz chirp sub-bottom profiler. The survey was conducted aboard the M/V Megan Miller August 9-13, 2007. The study area covers 35 square kilometers from about 0.2 km to 5-km offshore of the south shore of Martha's Vineyard, and ranges in depth from ~ 5 to 20 meters. Purpose: This dataset contains shot point navigation at 100 shot intervals for approximately 680 km of EdgeTech SB-512i chirp seismic-reflection data collected by the U.S. Geological Survey during Woods Hole Science Center cruise 07011 off the southern shore of Martha's Vineyard, MA, 2007. The shot point data are provided to correlate with the JPEG images of the seismic profiles.

Logical_Consistency_Report: Shot point navigation at 100 shot intervals was evaluated (i.e. quality control) during processing and all spurious data points were removed. Completeness_Report: Shot point navigation at 100 shot intervals for all seismic data were evaluated and all valid data were included in the shot point navigation file. Line 92 was saved as l91f1_001 during acquisition. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The EdgeTech SB-0512i was towed approximately 5 meters astern and approximately 1.5 meters below the sea surface. A GPS navigation receiver was mounted on the seismic sled to provide seismic navigation. GPS positions were sent, via radio modem, to a receiver positioned on the aft roof of the acquisition van aboard the R/V Megan Miller. GPS positions were sent directly to the EdgeTech J-Star seismic acquisition software. The horizontal accuracy of GPS is assumed to be ± 10 m (http://www.navcen.uscg.gov/).

EdgeTech J-Star seismic acquisition software was used to control the Geo-Star topside unit and digitally log trace data in the EdgeTech JSF format (http://www.edgetech.com/productlinemarine.html). Data were acquired using a 0.25-s shot rate, 5-ms pulse length and a 0.5-to-8.0 kHz swept frequency. Recorded trace lengths were approximately 250-ms. Trackline spacing varied from 40 meters in water depths less than 15 meters to 70-meter spacing in water depths greater than 15 meters. Shore perpendicular tracklines spacing ranged from 500 m to 1 km apart. Process_Step: Process_Description: A C program 'jsftosegy' (no version), developed by Tom O'Brien (USGS - Woods Hole Seafloor Mapping Group) was used to convert raw chirp traces in the EdgeTech JSF format (acquired using EdgeTech J-Star software) to chirp-processed, envelope traces in the SEG-Y rev. 1 standard format.

Geographic coordinates (WGS84) were converted to UTM zone 19 coordinates (WGS84) using Proj (version 4.6.0). Before saving the header information to a text file, the data were filtered using AWK (no version) to save only intervals of every 100 shot point locations retaining the first and last shot of each line. An additional AWK script was then used to convert time of day (UTC) to individual fields of hour, minute and second. The 100 shot interval navigation for each seismic line were then concatenated into a comma delimited (.csv) text file.

The event theme was then saved to a point shapefile and the projection was defined as Geographic Coordinate System, WGS84 (GCS_WGS_1984). The point shapefile was visually inspected for spurious data points and these data points were manually deleted.

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.). Reordered the links in the identification section so a landing page link is first. Attempted to modify http to https where appropriate. 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. 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.
