Description:
Abstract:
The USGS Woods Hole Science Center conducted a nearshore geophysical survey offshore of the southern coast of Martha's Vineyard, in the vicinity of the Martha's Vineyard Coastal Observatory (MVCO) in August 2007. 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 trackline navigation 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, 2007. These lines, in conjunction with the shot-point navigation can be used to correlate the seismic-reflection profiles with other data in the GIS.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
All attributes were evaluated during processing as standard quality control to ensure attributes contain accurate and relevant information and values.
Logical_Consistency_Report:
Seismic trackline navigation was generated from unique shot navigation for the seismic system. The unique shot navigation data were evaluated during processing for spurious points; all spurious points were removed prior to generating the trackline navigation.
Completeness_Report:
Trackline navigation for all seismic data were used to generate this shapefile. 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/>).

Approximately 680 km of high-resolution chirp seismic-reflection profiles were collected using an EdgeTech Geo-Star FSSB sub-bottom profiling system and an SB-0512i towfish (0.5-12 kHz) mounted on a catamaran and towed off the stern of the R/V Megan Miller. 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_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.

Process_Description:
A script was executed using Seismic Unix (version 4.1) to read the SEG-Y files, write a Seismic Unix file, and extract SEG-Y trace header information, which included shot number, longitude, latitude, year, filename, Julian day, and time of day (UTC). 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 unique shot point locations. An additional AWK script was then used to convert time of day (UTC) to individual fields of hour, minute and second. The unique shot navigation for each seismic line were then concatenated into a comma delimited (.csv) text file.

Process_Description:
The text file (*.csv) was imported into ESRI ArcMap 9.2 using Tools - Add XY Data and converted to an event theme. 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.

Process_Description:
The point shapefile containing unique shot point positions was used as an input for a VACExtras (version 1.8), a VB collection of tools developed by VeeAnn Cross (USGS-WHSC), which converts point data to a new polyline shapefile, based on the order of records contained within one attribute field. The shot number field was used to define the point order.
