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:
The sidescan-sonar mosaic will be used to identify bedforms and surficial sediment distribution in the vicinity of the Martha's Vineyard Coastal Observatory. The composite image will also be used as a base map for divers to collect sediment cores at fine and coarse sand boundaries prior to placement of oceanographic instruments.

Data_Quality_Information:
Logical_Consistency_Report:
All sidescan-sonar data were collected with a Klein dual-frequency sidescan-sonar system. The 100-kHz data were used to generate the sidescan-sonar mosaic. Quality control during data processing minimized any data inconsistencies and/or anomalies. All data were processed with a similar methodology.
Completeness_Report:
All available data were used to create the backscatter mosaic. Sidescan-soar data were collected along shore-parallel tracklines. Sonar data were not acquired along shore-perpendicular tie lines. Data gaps within the sidescan-sonar image correspond to slight course change to steer around MVCO 12-meter node and ASIT. Additional gaps are due to obstacle avoidance and removal of poor quality data during QC (e.g. 100 meter data gap between tracklines 4 and 6).
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 towfish 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 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_Step:
Process_Description:
XSonar/ShowImage sidescan-sonar processing software (version: none) was used to process the raw XTF sonar data following the methodology of Danforth, (1997). A 4 across track x 3 along track pixel median filter was applied to the raw sidescan-sonar data to remove speckle noise and a normalization of 4095 was applied to adjust the dynamic range within the output processed file. Processed data are stored as 8-bit. Navigation were also extracted from the raw data at a 1-minute interval and saved in ASCII file. Quality checks were conducted on the navigation to eliminate spurious or duplicate navigation fixes. The sonar data were further processed to correct for towfish altitude (i.e. proper tracking of the seafloor), and slant-range and beam pattern distortions inherent in the sonar data. Processed sonar files were then merged with the edited navigation. Processed sonar files were then mapped at a 0.5-meter resolution in UTM coordinates (UTM, Zone 19N, WGS84, meters) and saved in two XSonar/ShowImage mosaic files representing odd and even (i.e. every other line) sonar tracklines, or files.

The odd and even tiff images were then imported into PCI Geomatica Software (version 10.1) and digitally mosaicked at a 0.5-meter pixel resolution using PCI's OrthoEngine based on the procedures described in Paskevich (1996). The composite mosaic was registered in the UTM (Zone 19N, WGS84, meters) coordinate system and exported as a GeoTIFF image. . A TIFF world file was also generated for those who can't read a GeoTIFF.

The TIFF image was then imported to Adobe Photoshop CS3 in order to adjust the 8-bit range of the image file, so that areas of no data (i.e. the background) are represented by a pixel value of 255 and areas of data range from pixel values of 0 to 250.

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.
