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.
This data set contains 10 second navigation fixes for approximately 1010 km of swath bathymetric data collected by the U.S. Geological Survey during a Woods Hole Science Center cruise 07011 off the southern shore of Martha's Vineyard, 2007.

All data were evaluated during processing as a standard quality control procedure. Any spurious navigation fixes were flagged and filtered during processing of the raw bathymetric data, thus not included in this dataset.
All bathymetric data collected during USGS cruise 07011 off of the south shore of Martha's Vineyard were used to generate the bathymetric 10 second navigation shapefile.
Differential Global Positioning System (DGPS) navigation data were acquired with the forward, or primary, F180R DGPS antenna and transmitted via a network connection to the SWATHplus data collection software. The F180R motion reference unit consists of 2 L1 antennas used for position and heading. The antennas are mounted on a rigid horizontal pole and are offset from the MRU in a forward/aft configuration (see full description of F180R under motion below). DGPS accuracy is 1 to 3 meters, depending on the distance from a US Coast Guard coastal repeater station (http://www.navcen.uscg.gov/).

Swath bathymetric data were collected using an SEA Ltd SWATHplus 234-kHz Interferometric Bathymetric Sonar (http://www.sea.co.uk/swathplus.aspx?nav=products ) during survey operations. The SWATHplus system was mounted as a sidemount and positioned on the starboard side of the R/V Megan Miller. 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 by SEA software SWATHplus in the SWATHplus SXR format. Data collection parameters are saved into a SWATHplus session file in SEA's sxs format that can be later used for data replay.
Pitch, roll, heading, and heave information were recorded using a Coda Octopus F180R motion reference unit (MRU) (see: http://www.codaoctopus.com/motion/f180/index.asp) and transmitted via network connection to the SWATHplus data collection software. The MRU sensor was mounted directly above the SWATHplus transducers, thereby minimizing "lever arm" offsets which can lead to positioning and depth errors in the bathymetric data. The F180R series MRU uses two L1 antennas for position and heading accuracy. These were mounted directly above the MRU with an offset of 6.76 meters. The antennas are mounted on a rigid horizontal pole with a separation of 1 meter and are offset from the MRU in a forward/aft configuration. The forward offset of the primary antenna from the MRU is 0.5 meters, with no port/starboard offset.
Sound Velocity Profiles (SVP): Fourteen sound velocity casts were collected at various intervals during the USGS cruise 07011 using an Applied Microsystems SV Plus v2 instrument (see http://www.appliedmicrosystems.com/products/productDetails.aspx?id=1 for details). Sound velocity profiles (SVP) were generally collected at the eastern and western ends of the survey area, corresponding to the start and/or end of geophysical line data collection. This procedure was primarily followed to coordinate collection of SVP casts with the beginning or end of trackline. This was acceptable because only small variations in the speed of sound were noted throughout the survey area and negligible refraction artifacts were visible within the swath bathymetric data.
Ten second navigation data were extracted from raw swath bathymetric files (SWATHplus SXR format) using SwathEd (no version) bathymetric processing software's 'unravel' routine (Beaudoin, 2002) and saved as ASCII text files for each bathymetric file.

A C-shell script was used to reformat the output of the ASCII text files to include: easting, northing, line number, Julian day, hour, minute, second, longitude, latitude, and concatenate the line files into one comma-delimited ASCII text file.

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).

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. 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.
