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 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 (5-30 m deep) of Massachusetts between the New Hampshire border and Cape Cod Bay. 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/html/current_map.html). This spatial dataset is from the study area located between Duxbury and Hull Massachusetts, and consists of high-resolution geophysics (bathymetry, backscatter intensity, and seismic reflection) and ground validation (sediment samples, video tracklines and bottom photographs). The data were collected during four separate surveys conducted between 2003 and 2007 (NOAA survey H10993 in 2003, USGS-WHSC survey 06012 in 2006, and USGS-WHSC surveys 07001 and 07003 in 2007) and cover more than 200 square kilometers of the inner continental shelf.
This dataset contains trackline navigation for approximately 1930 km of Klein 3000 sidescan-sonar data collected by the U.S. Geological Survey during two Woods Hole Science Center cruises (06012 and 07001) offshore of Massachusetts between Duxbury and Hull.

All attributes were checked in a consistent manner.
Any spurious data points were removed during processing. Because this dataset is made up of data from multiple surveys, duplicate names may exist for the FILENAME field; however, this is very unlikely based on the file-naming scheme of "lLLfN_YYMMDDHHMMSS" where LL=line number; N=file number; YY=year; MM=month; DD=day; HH=hour; MM=minute; SS=seconds (date/time based on UTC time). Note that the underscore is sometimes omitted during acquisition and is therefore missing in the filename.
Only the subset of sidescan-sonar trackline navigation data collected during field activities 06012 and 07001 that are within the study area between Duxbury and Hull have been included in this spatial dataset. Trackline navigation for approximately 945 km of additional sidescan-sonar data collected south of Brant Rock, Massachusetts during these field activities will be published in a subsequent data release focused on Cape Cod Bay.
This shapefile includes trackline navigation from all the sidescan sonar data that was collected within the survey area; however only quality sonar data along the main survey lines were included in the sidescan sonar mosaic included on this report (DH_USGS_backscatter1m.tif). Sonar data from the tielines were not mosaicked.
Field activity 06012: The Klein 3000 was towed from the stern A-frame of the R/V Megan T. Miller. Position data were provided by the Z-Surveyor Extreme for real-time kinematic (RTK) navigation and recorded to the raw data files (XTF) via SonarPro (version 9.6) on the sonar acquisition computer. During some portions of the survey, technical difficulties caused the GPS systems to malfunction; in some instances the acquisition systems fell back on the RTK Float or the autonomous GPS navigation; but in some cases surveying was halted until a reliable GPS signal could be achieved. Layback positions, which account for the linear distance between the shipboard RTK-GPS receiver and the towed sonar vehicle were measured by a cable counter on the winch that was used to deploy the sidescan-sonar towfish. Layback offsets were directly applied into the acquisition software so the navigation recorded in the XTF data reflect the position including the layback offset. A conservative estimate of positional accuracy is estimated to be ± 10 m although when the system was recording RTK navigation the positional accuracy is likely <1 m as RTK-GPS provides horizontal positional accuracies on the decimeter scale. Positional uncertainty arises because 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. Field activity 07001: The Klein 3000 was towed from the port side aft on the R/V Rafael at a fixed distance that was accounted for during acquisition. Position data were provided by the Ashtech Extreme for real-time kinematic (RTK) navigation and recorded to the raw data files (XTF) via SonarPro (version 10.0) on the sonar acquisition computer. A conservative estimate of positional accuracy is estimated to be ± 10 m although when the system was recording RTK navigation the positional accuracy is likely <1 m as RTK-GPS provides horizontal positional accuracies on the decimeter scale.

Trackline acquisition for sidescan-sonar data for USGS surveys 06012 and 07001: Sidescan sonar data were collected with a Klein 3000 dual frequency (132/445 kHz) sidescan sonar towfish on the R/V Megan T. Miller (06012) and the R/V Rafael (07001). During survey 06012 the sonar was towed from the stern A-frame of the R/V Megan T. Miller; a cable counter measured the towfish layback and automatically adjusted the layback parameter in the acquisition software (SonarPro version 9.6). During survey 07001, the sonar was towed from the port side aft on the R/V Rafael; layback was fixed and SonarPro version 10.0 was used on the acquisition computer. Tracklines are generally spaced 100m apart (200m in the northern area where the USGS data overlaps with NOAA multibeam echo-sounder data). Data were acquired roughly parallel to the shoreline at an average speed of 5 knots.
Navigation was extracted at a 1 minute interval from the raw sidescan sonar data (XTF format) in XSonar (version: 1.1) using the 'demultiplex' function (Danforth and others, 1991). Spurious fixes were removed or corrected when possible. The XSonar generated navigation was reformatted and concatenated for each survey (using shell scripts convertXsonarNav (version 1.2sa) and Xsonar2ArcNav (version 1.2sa)) into comma-separated value (CSV) text files for input into ArcGIS (version 9.3). Survey ID (06012 or 07001) were appended to each record in the CSV files. The CSV files were combined into a single CSV file prior to import into ArcGIS. [output files: 06012_SonarnavLines.csv and 07001_SonarnavLines.csv > SouthShore_k3k_nav_all.csv]

VAC Extras tool (version: 2.04 FeatConv - Points to Line v2; USGS in-house software) was then used within ArcMap (version 9.3) to convert the navigation points to a trackline shapefile. The trackline shapefile was checked to ensure there were no spurious navigation fixes . XTools Pro (version 5.3.0) for ArcGIS desktop was used (Table Operations - Table Restructure) to reorganize and add fields to the polyline shapefile's attribute table. Table attributes for the survey ID ("SURVEYID') and Julian day ('JULDAY') of data collection, were already populated. Fields for device used to collect the data ('DEVICEID'), survey vessel name ('VEHICLEID'), and year ('YEAR') were added and populated using the table editor in ArcMap (version 9.3). The length field ('LENGTH') was populated using 'Calculate Geometry' (Property=Length; Use coordinate system of the data frame=WGS 1984 UTM Zone 19N; Unit=Kilometers), which can be accessed by right-clicking on the attribute field name in the table view.

Edits to the metadata were made to fix any errors that MP v 2.9.30 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. The source information was incomplete and had to be modified to meet the standard. The format of the time period of content had to be fixed. Other minor edits were probably performed (title, publisher, publication place, etc.). 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.
