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 620 km of shore-parallel sidescan-sonar data collected by the U.S. Geological Survey off the southern shore of Martha's Vineyard, 2007.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Attributes relay information about the object ID (i.e. polyline), date of data collection, type of sonar system used to acquire data, the frequency of the sonar system, swath width of the sonar system, USGS unique cruise identification, and the length of tracklines (km). Attributes were checked for consistency and for accuracy of descriptive information.

Logical_Consistency_Report:

Trackline navigation were edited during processing in order to remove spurious navigation fixes.

Completeness_Report:

All available data were used to create the trackline navigation. Sidescan-sonar data were only collected along shore-parallel tracklines; sonar data were not collected along shore-perpendicular tie lines.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Differential Global Positioning System (DGPS) navigation data were acquired with a LGBX Pro receiver and sent directly to the sidescan-sonar acquisition software, L3-Klein Associates, SonarPro. The LGBX Pro received DGPS positions from a DGPS antenna located on the starboard, aft roof of the acquisition van. The layback of the sidescan-sonar towfish was measured with a digital block cable counter. The cable counter data were sent directly to SonarPro as a serial string. SonarPro computes the actual tow-fish position using the DGPS input and the layback. The following offsets are measured prior to deployment of the sidescan-sonar tow-fish and entered into SonarPro: height of the block, offset from DGPS antenna to the block, and height of the DGPS antenna above the waterline. Prior to deploying the sidescan-sonar tow-fish, the tow-fish is hauled to the block in order to zero the cable counter. DGPS accuracy is 1 to 3 meters, depending on the distance from a US Coast Guard coastal repeater station (http://www.navcen.uscg.gov/).

Data were acquired with an L3-Klein Associates 3000 digital, dual-frequency, sidescan-sonar (www.l-3klein.com). Dual frequencies are nominally 100 (132 kHz) and 500 (445 kHz) kHz. The sidescan-sonar was towed aft of the R/V Megan Miller. A digital cable-out display was used to measure tow-fish layback. Layback and DGPS input were used by the SonarPro acquisition software to calculate position of the sonar tow-fish and store in the raw data files. Line spacing varied from 40 meter in ~ 5 to 15 meter water depth to 75 meters in ~15 - 25 meter water depth. Data files were recorded with SonarPro 10.0 in XTF (extended-Triton Format) format at a 0.03-sec ping rate yielding a 50-meter range (100-meter swath). The 100 kHz data were used to generate the sidescan-sonar mosaic. The data range within the sidescan-sonar mosaic (digital number values (DN) of the 8-bit image) is 0 - 250, with the background value (i.e. No DATA) set to 255.

Process_Description:

Navigation data were extracted at 1 minute intervals from the raw sidescan sonar data (XTF format) during the 'demultiplex' phase of data processing within XSonar/ShowImage sidescan-sonar processing software (Danforth and others, 1991) and stored in ASCII files. Software: XSonar/ShowImage (no version)

The ASCII 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.

The point shapefile containing 1-minute navigation was used as an input for VACExtras (version 1.8), a Visual Basic 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 line number field was used to define the point order.

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.). Reordered the links in the identification section so a landing page link is first. Attempted to modify http to https where appropriate. Online link was added to a cross-reference. 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.
