Description:
Abstract:
These data were collected under a cooperative agreement with the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS), Coastal and Marine Geology Program, Woods Hole Coastal and Marine Science Center (WHSC). Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of sea-floor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters of coastal Massachusetts, primarily in water depths of 3-30 meters deep. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (http://woodshole.er.usgs.gov/project-pages/coastal_mass/). The data collected in the study area located in Vineyard Sound Massachusetts includes high-resolution geophysics (bathymetry, backscatter intensity, and seismic reflection). The data were collected during three separate surveys conducted between 2009 and 2011and cover approximately 340 square kilometers of the inner continental shelf. More information about the individual USGS surveys conducted as part of the Vineyard Sound project can be found on the Woods Hole Coastal and Marine Science Center Field Activity webpage: 2009-002-FA: http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2009-002-FA 2010-004-FA: http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2010-004-FA 2011-004-FA: http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2011-004-FA
Purpose:
The purpose of these data is to provide the trackline navigation and filenames of all the acoustic backscatter data acquired using a Klein 3000 sidescan-sonar within the Vineyard Sound survey area during these surveys.

Attribute_Accuracy_Report: All attributes were checked in a consistent manner.
Logical_Consistency_Report:
Navigation data were extracted from the header of the raw line files. They have been compared to other navigation data collected during the cruise for consistency. Any spurious data points were removed during processing.
Completeness_Report:
Only the subset of sidescan-sonar trackline navigation collected during field activities 2009-002-FA, 2010-004-FA, and 2011-004-FA that are within the Vineyard Sound survey area are included in this spatial dataset.

Horizontal_Positional_Accuracy_Report:
Field activity 2009-002-FA: The Klein 3000 was towed from the stern A-frame of the M/V Megan T. Miller. Differential GPS (DGPS) position data were provided by the Ashtech BRG2 receiver and recorded to the raw data files (XTF) via SonarPro (version 10.0) on the sonar acquisition computer. The GPS antenna was mounted on the aft end of the acquisition lab van. All GPS data during this survey was referenced to the WGS84 horizontal datum. The horizontal offsets between the GPS antenna and the sheave on the A-frame were measured prior to the survey (x: -2.0m; y:-8.35m; z:+2m). Additional layback position, accounting for the linear distance between the sheave on the A-frame and the towed sonar system were measured by a 3PS digital block cable counter on the winch that was used to deploy the sidescan-sonar towfish. All of the horizontal offsets were directly applied into the acquisition software so the navigation recorded in the XTF data reflect the position including the layback offset. The layback calculations do not account for fish motion behind the vessel, which is caused by sea state and vessel speed-induced changes in the angle and scope of the tow cable. DGPS positional accuracy is estimated to be within 3-5 m; Wide Area Augmentation System enable DGPS is estimated to be within less than 3 m. Considering the additional fish motion and cable movement, a conservative estimate of positional accuracy for this dataset is estimated to be within 10 m. Field activity 2010-004-FA: The Klein 3000 was towed from the stern A-frame of the M/V Megan T. Miller. Real-Time Kinematic (RTK) GPS position data were provided by the Novatel DL-V3 receiver and recorded to the raw data files (XTF) via SonarPro (version 11.0) on the sonar acquisition computer. The GPS antenna was mounted on the top of the SWATHplus (interferometric bathymetry) transducer pole, midship on the starboard side (the middle of the 3 bathymetry system antennas). On a few brief occasions the RTK-GPS signal was lost and the navigation system fell back to standalone DGPS or GPS mode. In these cases, the lower quality positions were used and no corrections were made for RTK navigation gaps. All GPS data during this survey were referenced to the WGS84 horizontal datum. The horizontal offsets between the GPS antenna and the sheave on the A-frame were measured prior to the survey (x:-4.1m; y:-14.94m; z:-1.33m). Additional layback position, accounting for the linear distance between the sheave on the A-frame and the towed sonar system were measured by a 3PS digital block cable counter on the winch that was used to deploy the sidescan-sonar towfish. All of the horizontal offsets were directly applied into the acquisition software so the navigation recorded in the XTF data reflect the position including the layback offset. The layback calculations do not account for fish motion behind the vessel, which is caused by sea state and vessel speed induced changes in the angle and scope of the tow cable. RTK positional accuracy is estimated to be within less than 1 m. Taking the additional fish motion, cable movement and RTK-GPS navigation dropouts into account, a conservative estimate of positional accuracy for this dataset is estimated to be within 10 m. Field activity 2011-004-FA: The Klein 3000 was towed from the stern A-frame of the M/V Scarlett Isabella. Differential GPS (DGPS) position data were provided by the Ashtech BRG2 receiver and recorded to the raw data files (XTF) via SonarPro (version 11.0) on the sonar acquisition computer. The GPS antenna was mounted on the forward end of the acquisition lab van. All GPS data during this survey was referenced to the WGS84 horizontal datum. The horizontal offsets between the GPS antenna and the sheave on the A-frame were measured prior to the survey (x: +4.31m; y:-9.18m; z:0.0m). Additional layback position, accounting for the linear distance between the sheave on the A-frame and the towed sonar system were measured by a 3PS digital block cable counter on the winch that was used to deploy the sidescan-sonar towfish. All of the horizontal offsets were directly applied into the acquisition software so the navigation recorded in the XTF data reflect the position including the layback offset. The layback calculations do not account for fish motion behind the vessel, which is caused by sea state and vessel speed induced changes in the angle and scope of the tow cable. DGPS positional accuracy is estimated to be within 3-5 m; WAAS enable DGPS is estimated to be within less than 3 m. Taking the additional fish motion and cable movement into account, a conservative estimate of positional accuracy for this dataset is estimated to be within 10 m.

Process_Description:
Step 1. Navigation was extracted at a 1 minute interval from raw sidescan sonar data (XTF format) and saved to ASCII text using the XSonar (version 1.1) 'demultiplex' function (Danforth 1997). Individual ASCII navigation files were concatenated by survey (using shell scripts convertXsonarNav (no version) and Xsonar2ArcNav (no version)) into comma-separated value (CSV) text files with the following attributes: East, North, JD, Line, Lon, Lat. Processing occurred in 2009, 2010, and 2011.

Step 2. In ArcCatalog (version 9.3), the ASCII navigation file in CSV format for each survey was converted to a point feature class using ArcCatalog (version 9.3) by right-clicking on the comma separated text file, selecting "Create Feature Class from XY table", and specifying the output file "SurveyName"_k3k_navpts.shp in geographic coordinates. Processing occurred in 2009, 2010, and 2011.

Process_Description:
Step 3. Convert Points to Lines. The VAC Extras tool (version 2.04; USGS in-house software)Feature Conversion- points to Lines (version 2) tool was then used within ArcMap (version 9.3) to convert the point shapefile for each survey into a polyline shapefile by connecting sequential points with a line based on a unique identifier (Line attribute). In addition the first occurrence of the Julian Day (JD) for each line was carried over to the polyline shapefile. Text attribute for "Survey" and "Vessel" were added to each shapefile and the values were calculated using the "Field Calculator" in the context menu in ArcCatalog (version 9.3). The backscatter tracklines from each of the three surveys were merged into one shapefile (VS_BackscatterTracklines.shp) using the "Merge" tool in ArcToolbox (version 9.3). During the merge process the input shapefiles were in UTM Zone 19, WGS84, and the output projection of VS_BackscatterTracklines.shp was defined as Geographic, WGS84.

Process_Description:
Edits to the metadata were made to fix any errors that MP v 2.9.32 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.). The link to the data in the Identification_Information section had to be fixed. Fixed a link to the project page in the abstract. 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.
