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 1-minute navigation positions 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 type (i.e. point), positions, line number, Julian Day, Time and USGS unique cruise identification number. Attributes were checked for consistency and for accuracy of descriptive information.
Logical_Consistency_Report:
1-minute navigation positions were edited during processing in order to remove spurious points.
Completeness_Report:
All available data were used to create the 1-minute navigation shapefile. 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.

Process_Description:
A c-shell script was used to reformat the output from degrees decimal minutes to decimal degrees. Proj (version 4.6.1) and AWK (GNU 3.1.5) were used to convert decimal degrees to eastings and northings (based on UTM Zone 19 N, WGS84) and to reformat the output as a comma delimited ASCII file including headers listing field names (Easting, Northing, Line Number, Julian Day, Hour, Minute, Second, Longitude, Latitude).

Process_Description:
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.
