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 GeoTIFF (Tagged Image File Format) contains approximately 45 square-km of RESON SeaBat 8101 and 8125 multibeam-echosounder backscatter data that were collected by the National Oceanic and Atmospheric Administration during hydrographic survey H10993 offshore of Massachusetts, in the approaches to Boston Harbor near Hull. These data are used to define the sea-floor morphology as part of the Massachusetts Sea-floor Mapping Project.

Attribute_Accuracy:
Attribute_Accuracy_Report:
Image pixel values contain acoustic reflectivity values normalized to an 8-bit data range (0-255). Low-backscatter is represented by dark tones (low values) and high-backscatter is represented by bright tones (high values).
Logical_Consistency_Report:
This image represents backscatter imagery from multibeam echosounder sonar data along the main survey lines; no crossline data were included in this image. Gaps may occur along-track and between adjacent lines. Significant tonal variation occur as a result of different sonar equipment and changes in acquisition setting that were not able to be accounted for in the processing.
Completeness_Report:
This backscatter mosaic was created from the subset of multibeam-echosounder backscatter data collected during NOAA hydrographic survey H10993 that are within the study area between Duxbury and Hull. Additional multibeam-echosounder data located outside the Duxbury to Hull study area were not processed. Some sections of sonar data with excess noise may have been clipped during processing. No additional visual enhancement was performed.

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.

For NOAA Hydrographic survey H10993: Launch 1005 acquired multibeam-echosounder data using a hull-mounted RESON SeaBat 8101 multibeam system. All positioning and attitude on Launch 1005 were determined with a TSS POS/MV 320 (version 2) GPS aided inertial navigation system. Launch 1014 acquired multibeam-echosounder data using a hull-mounted RESON SeaBat 8125 multibeam system. For continuous refraction correctors at the transducer, a Digibar Pro was used for the surface sound velocity and all positioning and attitudes on Launch 1014 were determined with a TSS POS/MV 320 (version 3) GPS-aided inertial navigation system. The RESON SeaBat 8101 is a 1.5 deg beam angle system which operates at a frequency of 240 kHz and collects 101 individual soundings in a swath oriented perpendicular to the vessel track. The RESON SeaBat 8125 is a 0.5 deg 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. Sounding positional control 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 this survey was Portsmouth Harbor, NH (Beacon # 771). No horizontal control stations were established for this survey. NOAA's Computer Aided Resource Information System (CARIS) directory with all of the processed multibeam bathymetric data was provided to the USGS. The raw eXtended Triton Format (XTF) multibeam backscatter data from NOAA survey H10993 was also delivered to the USGS where it was processed using a radiometric-correction technique developed by the Ocean Mapping Group and the University of New Brunswick (Beaudoin and others, 2002). 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. No additional visual enhancement was performed. Significant tonal variation occurs in this dataset as a result of the system parameters during acquisition.

Process_Description:
Each survey day was individually mosaicked into a separate mosaic file (MOS) with the bounds of the entire H10993 survey area and converted to a Portable GrayMap image (PGM) using SwathEd (build January2008) software. The PGM files were then converted to TIFF images using ImageMagick (v6.3.7). TIFF World Files (TFW) were created for each TIFF image from the MOS files using the SwathEd command "edhead."

Process_Description:
The TIFF images for each individual survey day were combined using Adobe Photoshop (CS2); the backscatter from the hull-mounted multibeam system displayed no layback offset that needed to be accounted for. No additional visual enhancement was performed. Significant tonal variation occurs in this dataset as a result of the system parameters during acquisition.

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 distribution format was modified in an attempt to be more consistent with other metadata files of the same data format. 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.
