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 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.
Purpose:
This data set contains trackline navigation for approximately 3240 km of interferometric (Systems Engineering and Assessment Ltd. (SEA) SWATHPlus-M) and multibeam (RESON SeaBat 8101 and 8125) bathymetric sonar data that were collected by the U.S. Geological Survey and the National Oceanic and Atmospheric Administration, respectively, during three surveys (NOAA survey H10993 and USGS surveys 06012 and 07001) offshore of Massachusetts, between Duxbury and Hull.

Attribute_Accuracy:
Attribute_Accuracy_Report: All attributes were checked in a consistent manner.
Logical_Consistency_Report:
Any spurious data points were removed during processing. Duplicate names may exist for the FILENAME field; however further querying the data by SURVEYID will distinguish a unique trackline for each record in this spatial dataset.
Completeness_Report:
Only the subsets of interferometric bathymetric sonar collected during field activities 06012 and 07001 that are within the study area between Duxbury and Hull have been included in this spatial dataset. Approximately 945 km of additional bathymetric 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. Additionally, only a portion of the multibeam bathymetric sonar trackline data acquired during NOAA hydrographic survey H10993 is included in this shapefile. To review additional data collected during this survey, please refer to the descriptive report for the survey which can be accessed online by visiting http://www.ngdc.noaa.gov/mgg/bathymetry/hydro.html and entering "H10993" into the "Survey" section of the "Text search of NOS data & products" dialog. This shapefile includes trackline navigation from all the swath sonar data that was collected within the survey area; however only quality bathymetric soundings along the main survey lines were included in the final bathymetry grid included on this report (DH_bathy5m). Bathymetric data along the tielines, line l67f2 and sections of other main survey lines (mostly during leg 1 of survey 06012, see below for more information) were not included in the final bathymetric grid. The GPS navigation and bathymetric attitude data were significantly hindered during the first leg of survey 06012 (lines l1f1 - l99f2, 4-14 Aug 2006). Navigation dropouts halted surveying and problems with the ADU2 compass resulted in un-usable bathymetric data along survey tracklines that have valid navigation data. Therefore, tracklines of good navigation occur in areas where there are gaps in the bathymetry coverage as illustrated in the dataset DH_bathyhlshd_wgaps.tif, included in this report.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Hydrographic survey H10993: Horizontal sounding positional control for the NOAA H10993 survey was determined using the Global Positioning System (GPS) corrected by U.S. Coast Guard Differential GPS (DGPS) beacon stations. The primary and only DGPS beacon used for survey H10993 was Portsmouth Harbor, NH (Beacon No. 771). No horizontal control stations were established for the NOAA survey. Additional information may be found in the NOAA Descriptive Report for survey H10993, the Data Acquisition and Processing Report, and the Horizontal and Vertical Control Report. Field activity 06012: The SWATHPlus transducers were mounted on a rigid pole, approximately 2.6 m below the water line, along the starboard side of the R/V Megan T. Miller. Position data were provided by the Z-Surveyor Extreme for real-time kinematic (RTK) navigation (the Ashtech BR2G DGPS was used as a backup navigation system) and recorded to the raw data files (SXR) via SWATHPlus (version 2.07) on the 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. 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 (http://www.noaa.gov; http://www.nos.noaa.gov; http://www.ngs.noaa.gov). Field activity 07001: The SWATHPlus transducers were mounted on a rigid pole, approximately 0.5 m below the water line, from the bow of the of the R/V Rafael of Woods Hole, MA. Position data were provided by the Ashtech Extreme for RTK navigation (the Ashtech BR2G DGPS was used as a backup navigation system) and recorded to the raw data files (SXR) via SWATHPlus (version 3.X) on the 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 (http://www.noaa.gov; http://www.nos.noaa.gov; http://www.ngs.noaa.gov).

Bathymetric sonar data acquisition H10993: Bathymetric sonar data were collected from launches 1005 and 1014 of the NOAA Ship Thomas Jefferson, S-222. Launch 1005 used a RESON SeaBat 8101 multibeam sonar system and Launch 1014 used a RESON SeaBat 8125 multibeam sonar system. Positioning and attitude information on both launches were determined using Applanix TSS POS/MV 320 (version 2) GPS aided inertial navigation systems. On Launch 1014, an Odom Hydrographic Digibar Pro sound velocimeter was used to continually measure changes in sound-velocity near the sea surface. Sonar data were collected along east-west oriented survey lines spaced between approximately 15 and 50 meters apart, providing 100 percent coverage of the seafloor. Data collected along several north-south oriented survey lines were used for survey line junction analyses subsequent to the application of tide corrections. To review more detailed information concerning data acquisition equipment, configuration, and settings on launches 1005 and 1014, please refer to the descriptive report for the survey H10993, which can be accessed online by visiting http://www.ngdc.noaa.gov/mgg/bathymetry/hydro.html and entering "H10993" into the "Survey" section of the "Text search of NOS data and products" dialog. Bathymetric sonar data acquisition 06012: Bathymetric sonar data were collected using a Systems Engineering and Assessment (SEA), Ltd. SWATHPlus-M (234 kHz) interferometric sonar system. The SWATHPlus transducers were mounted on a rigid pole, approximately 2.6 m below the water line, along the starboard side of the R/V Megan T. Miller of Port Jefferson, NY. An International Industries, Inc. TSS DMS 2-05 inertial-motion unit, mounted directly above the SWATHPlus transducers, measured vertical displacement (heave) and attitude (pitch and roll) of the vessel during data acquisition. Heading was determined using an Ashtech ADU2 for lines l1f1-l99f1, and a KVH compass (with processor calculated declination +15.583 to be applied during post-processing) for lines l99f2-end of survey. An Applied Microsystems Ltd. Micro SV sound velocimeter, mounted adjacent to the SWATHPlus transducers, continually measured changes in sound-velocity near the sea surface, and a hand-casted, Applied MicroSystems SV Plus sound velocimeter was used to collect sound-velocity profiles of the entire water column approximately every two hours. SWATHPlus acquisition software was used to control the transducers and digitally log sonar data across a 200 m swath in the SWATHPlus .SXR format. To obtain 100 percent coverage of the seafloor, sonar data were collected along northwest-southeast and north-south oriented survey lines that were spaced approximately 100 or 200 meters apart. Data collected along several northeast-southwest and east-west oriented survey lines were used for survey line junction analyses subsequent to the application of tide corrections. The R/V Megan T. Miller maintained an average speed of 5 knots during survey operations. Bathymetric sonar data acquisition 07001: Bathymetric sonar data were collected using a Systems Engineering and Assessment, Ltd. SWATHPlus-M (234 kHz) interferometric sonar system. The SWATHPlus transducers were mounted on a rigid pole, approximately 0.5 m below the water line, from the bow of the of the R/V Rafael of Woods Hole, MA. A CodaOctopus F-180 inertial-motion unit, mounted directly above the SWATHPlus transducers, measured vertical displacement (heave) and attitude (pitch and roll) of the vessel during data acquisition. An Applied Microsystems Ltd. Micro SV sound velocimeter, mounted adjacent to the SWATHPlus transducers, continually measured changes in sound-velocity near the sea surface, and a hand-casted, Applied MicroSystems SV Plus sound velocimeter was used to collect sound-velocity profiles of the entire water column approximately every two hours. SWATHPlus acquisition software was used to control the transducers and digitally log sonar data across a 150 m swath in the SWATHPlus .SXR format. To obtain 100 percent coverage of the seafloor, sonar data were collected along northwest-southeast and north-south oriented survey lines that were spaced approximately 100 m apart. Data collected along several northeast-southwest and east-west oriented survey lines were used for survey line junction analyses subsequent to the application of tide corrections. The R/V Rafael maintained an average speed of 5 knots during survey operations.

A series of 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_nav2.pl (which runs the CARIS program printfnav for all the lines in the HDCS dir) and the grep statement below. (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) > grep Accepted combined.txt > outputfile This step was done separately for the USGS surveys and the NOAA survey (06012, 07001 and H10993), creating the files 1.usgs_combined_grep.txt and 1.noaa_combined_grep.txt. Lines in the NOAA survey that fell outside the Duxbury to Hull survey area were removed from the navigation file. B. The two navigation files were concatenated together. > cat 1*.txt > 2.ss_combined_grep.txt C. The files extracted from CARIS HIPS have 4-5 navigation fixes per second.

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 (XYSS_bathyNAV_ofr.shp) to a temporary trackline shapefile (SS_bathyNAV_ofr_trk.shp). The trackline shapefile was checked to ensure no spurious fixes. XTools Pro (version 5.3.0) for ArcGIS desktop was used to reorganize and add fields to the polyline shapefile's attribute table. 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). Table attributes for the survey ID ("SURVEYID') and Julian day ('JULDAY') of data collection, were already populated but edited to be consistent with the other trackline shapefile in this report. 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.

Process_Description:
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.
