Abstract:
These data were collected under a cooperative agreement between 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 seafloor 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 5 to 30 meters (m) 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/html/current_map.html). The data collected in the study area in Buzzards Bay, Massachusetts, include high-resolution geophysics (bathymetry, backscatter intensity, and seismic reflection) and ground validation (sediment samples, video tracklines, and bottom photographs). The geophysical data are released in USGS Open-File Report 2012-1002, High-Resolution Geophysical Data from the Inner Continental Shelf: Buzzards Bay, Massachusetts (http://pubs.usgs.gov/of/2012/1002/). The sampling data have not been prepared for publication yet. The geophysical data were collected during four separate surveys conducted between 2004 and 2011 (National Oceanic and Atmospheric Administration (NOAA) survey H11319 (in 2004; bathymetry only) and USGS surveys 2009-002-FA, 2010-004-FA, and 2011-004-FA)) and cover 410 square kilometers of the inner continental shelf. More information about the individual USGS surveys conducted as part of the Buzzards Bay project can be found on WHCS Field Activity Web pages: 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 Information about the NOAA survey can be found at: H11319: http://surveys.ngdc.noaa.gov/mgg/NOS/coast/H10001-H12000/H11319/DR/
Purpose:
This dataset contains approximately 4770 linear kilometers of trackline navigation for interferometric (Systems Engineering and Assessment Ltd. SWATHPlus-M) and multibeam (RESON SeaBat 8125) bathymetry data collected by the U.S. Geological Survey and the National Oceanic and Atmospheric Administration, respectively, during four surveys (USGS surveys 2009-002-FA, 2010-004-FA and 2011-004-FA; and NOAA survey H11319 in 2004) offshore of Massachusetts, in Buzzards Bay. These data are used to define the seafloor morphology as part of the Massachusetts Seafloor Mapping Project.

Attribute_Accuracy:
Attribute_Accuracy_Report: All attributes were checked in a consistent manner.
Logical_Consistency_Report:
Any spurious data points were removed during processing. Because this dataset is made up of data from multiple surveys, duplicate filenames likely exist for these survey lines; however, an additional attribute (called 'UniqueLine') was created during the processing of this dataset to make a unique identifier for each survey line segment.
Completeness_Report:
Only the subset of swath-bathymetry trackline navigation collected within the Buzzards Bay study area during USGS field activities 2009-002-FA, 2010-004-FA, and 2011-004-FA are included in this spatial dataset. Trackline navigation for approximately 3,920 kilometers of additional swath-bathymetry data collected within Vineyard Sound, Massachusetts during these field activities were published in USGS Open-File Report 2012-1006 High-Resolution Geophysical Data from the Inner Continental Shelf: Vineyard Sound, Massachusetts (http://pubs.usgs.gov/of/2012/1006/). This shapefile includes trackline navigation from all the swath bathymetric data that was collected within the survey area. However, only quality sonar data along the main survey lines were included in the final bathymetry grid that is found on this report (BB_Bathy5m). Noisy or poor quality data were not included in the grid. Data from some survey lines were omitted where they overlapped with equal or better quality data from adjacent lines (as was the case for the few lines that were less than several hundred meters long). Data along tie and transit lines were not included in the final grid. Also, data from the southern extent of line l131f1 were omitted as they extended beyond the survey area boundary into an area covered by a previous NOAA survey (see NOAA Survey H11076 ftp://ftp.ngdc.noaa.gov/pub/coast/H10001-H12000/H11076/ and USGS Open File Report 2006-1357 http://pubs.usgs.gov/of/2006/1357/).

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Hydrographic survey H11319: Horizontal sounding positional control for the NOAA H11319 survey was determined using the Global Positioning System (GPS) corrected by U.S. Coast Guard Differential GPS (DGPS) beacon stations. The primary DGPS beacon used for survey H11319 was at Acushnet, MA and the secondary beacon was at Portsmouth, NH. No horizontal control stations were established for the NOAA survey. Additional information may be found in the NOAA Descriptive Report for survey H11319 and the Data Acquisition and Processing Report. Field activities 2009-002-FA and 2010-004-FA: Navigation was acquired with a Coda Octopus F180 Differential Global Positioning System + Wide Area Augmentation System (DGPS+WAAS); which are accurate to + or - 1 to 2 meters, horizontally. All DGPS data are referenced to WGS84. The SWATHPlus transducers were mounted on a rigid pole, approximately 2.46 m below the water line, along the starboard side of the M/V Megan T. Miller. The DGPS antenna was located on the same pole approximately 4.3m above the sea surface. These offsets were corrected within the SWATHPlus acquisition software. Field activity 2011-004-FA: Navigation was acquired with a Coda Octopus F180 Differential Global Positioning System + Wide Area Augmentation System (DGPS+WAAS); which are accurate to + or - 1 to 2 meters, horizontally. All DGPS data are referenced to WGS84. The SWATHPlus transducers were mounted on a rigid pole, approximately 2.17 m below the water line, along the port side of the M/V Scarlett Isabella. The DGPS antenna was located on the same pole approximately 4.6m above the sea surface. These offsets were corrected within the SWATHPlus acquisition software. The DGPS horizontal positional accuracy is estimated to be within 3-5 m; WAAS enable DGPS accuracy is estimated to be within less than 3 m and the accuracy of RTK-GPS (which was not applied to the horizontal positions for these surveys) is estimated to be less than 1 m. However, the U.S. Coast Guard maintains a maritime DGPS service providing 10 meter accuracy for the coastal areas of the continental US; therefore, a very conservative, worse-case estimate of the horizontal positional accuracy of this survey data is approximately 10 meters (although these systems have been shown to be reliable to less than 2m).

This trackline dataset is a combination of navigation data along which swath bathymetry was collected by the USGS (with a 234 kHz Systems Engineering and Assessment Ltd. (SEA) SWATHplus interferometric sonar mounted on the M/V Megan T. Miller (2009 and 2010) and the M/V Scarlett Isabella (2011)). Data were acquired between May 2009 and May 2011. USGS Configuration: Survey: Survey lines were run at an average speed of 5 knots and were spaced 50-100 m apart to obtain overlapping swaths of data and full seafloor coverage. Sonar: The SEA SWATHplus-M operates at a frequency of 234 kHz and a variable range (increased or decreased manually depending on water depth). The system was operated with a transmit power: 80 percent, a transmit length: 12 cycles (2009-002-FA and 2010-004-FA) or 43 cycles (2011-004-FA), 3072 samples per channel (2009-002-FA) or 4096 samples per channel (2010-004-FA and 2011-004-FA), and a variable range (increased or decreased depending on water depth). Additonal sonar configuration information can be found in the metadata for the bathymetry grid included with this report (USGS Open-File Report 2012-1002, High-Resolution Geophysical Data from the Inner Continental Shelf: Buzzards Bay, Massachusetts at http://pubs.usgs.gov/of/2012/1002/html/appendix1.html)

This trackline dataset contains the selected tracklines of navigation data along which swath bathymetry was collected by the NOAA (with a 455 kHz multibeam-echosounder mounted on the NOAA Ship RUDE(2004)). Data were acquired between March and April 2004. These are the selected survey lines that were need to complete the final bathymetry grid. The USGS surveyed around this known area during survey 2009-002-FA to save time and money by making use of exisitng high-quality bathymetry data. NOAA Configuration: Survey: All data were collected by the NOAA Ship RUDE. Trackline spacing for survey H11319 was based on an estimate of 2.5 times the water depth to achieve overlapping swaths for full seafloor coverage. For this area survey lines were typically between 25-50m apart. Ship speed was determined such that the survey achieved a sampling rate of 3.2 pings per 3 meters of along track distance. Sonar: The RESON SeaBat 8125 is a 0.5 degree (across-track) by 1 degree (along-track) beam angle system which operates at a frequency of 455 kHz and collects 240 individual soundings in a swath oriented perpendicular to the vessel track. The system is capable of ping rates ranging from 3.02 Hz to 40.05 Hz but for this survey, the maximum ping rate was set to 20 Hz. Other: All bathymetry processing, including navigation editing, was done by NOAA Hydrographers. NOAA's Computer Aided Resource Information System (CARIS) directory was provided to the USGS. Refer to the Fall Data Acquisition and Processing Report (DAPR) and the Horizontal and Vertical Control Report, for detailed equipment, vessel configuration and setting information. Additonal sonar configuration information can be found in the metadata for the bathymetry grid included with this report (USGS Open-File Report 2012-1002, High-Resolution Geophysical Data from the Inner Continental Shelf: Buzzards Bay, Massachusetts at http://pubs.usgs.gov/of/2012/1002/html/appendix1.html)

Process_Description:
Perl and AWK programming scripts were used to extract and subsample the navigation fixes stored in the CARIS HIPS database. The processing flow for this step follows: A. Extract navigation for each line in CARIS HDCS directory using Perl script do_CARIS_nav3.pl (which runs the CARIS program printfnav for all the lines in the HDCS dir). (Extracted navigation file is tab-delimited in format YYYY-JD HH:MM:SS:FFF DD.LAT DD.LONG SSSSS_VVVVV_YYYY-JD_LLLL AR where YYYY=year, JD=Julian Day, HH=hour, MM=minute, SS=seconds, FFF=fractions of a second, DD.LAT=latitude in decimal degrees, DD.LONG=longitude in decimal degrees, SSSSS=survey name, VVVVV=vessel name, LLLL=linename, AR=accepted or rejected navigation fix) This step creates the file combined.txt B. The navigation files extracted from CARIS HIPS contained 4-5 navigation fixes per second. These files were subsampled to produce files containing 1 fix per second using AWK to remove the fractions-of-a-second from the time column then grabbing the first occurrence of each second. > awk '{print $1" "substr($2,1,8)" "$3" "$4" "$5}' 2.combined.txt | awk '$2 != prev { print; prev = $2 }' > 3.BB_NAV_awked.txt C.

Process_Description:
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 'UniqFile' field was used to define which points were used to generate each polyline feature, and the first occurrence of fields 'FileName', 'Year', 'JulDay', 'SurveyID', 'VehicleID', and 'Time' and the last occurrence of 'Time' were chosen to be included as attributes in the output shapefile. The trackline shapefile was checked to ensure there were no severely spurious navigation fixes. XTools Pro (version 7.1.0) 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 unique file name ('UniqFile'), filename ('FileName'), survey ID ("SurveyID'), year ('Year'), Julian day ('JulDay') of data collection, survey vessel name ('VehicleID'), start time ('TimeStart') and end time ('TimeEnd') of each line were already populated but renamed if necessary. Field for device used to collect the data ('DeviceID') was added and then populated using field calculator and the table editor in ArcMap (version 9.3). The length field ('Length_km') was also added and then 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.

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 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.
