Description:
Abstract:
These data are high-resolution bathymetric measurements of the seafloor from Boston Harbor and the harbor approaches, Massachusetts. Approximately 170 km² of sidescan sonar and bathymetric data were collected by the National Oceanic and Atmospheric Administration (NOAA) Ship Whiting in 2000 and 2001 and reprocessed and gridded by the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS). Note: These data were converted from their native projection to the Massachusetts State Plane coordinate system, Mainland Zone (Fipszone 2001), meters by the Massachusetts Department of Coastal Zone Management on Oct. 1, 2006.
Purpose:
These data were collected by the National Oceanic and Atmospheric Administration (NOAA) National Ocean Service (NOS) branch as part of their periodic hydrographic mapping for nautical charting. The raw datasets were provided by NOAA to the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS) in Woods Hole, MA as part of a cooperative agreement to provide high resolution bathymetry and backscatter intensity maps and digital GIS information for resource management, scientific research, industry and the public.

Data_Quality_Information:
Logical_Consistency_Report:
These data have not been quantitatively compared to previous hydrographic data, although they generally agree with qualitative comparison of published NOAA charts.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
All of the NOAA survey vessels were equipped with Trimble DSM212L Differential Global Positioning System (DGPS) receivers. Launch 1005, which collected all of the multibeam bathymetry, was also equipped with a TSS POS/MV Model 320 (Position and Orientation System for Marine Vessels). Standard bathymetric processing, including tide corrections, soundings accuracy, and quality control were done by the NOAA Office of Coast Survey.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Tidal datum for this project is Mean Lower Low Water (MLLW). The tide station at Boston, MA (844-3970) was the control for the vertical datum.

Source_Contribution:
The original geophysical data for this project were collected during four hydrographic surveys conducted by NOAA NOS in 2000 and 2001 on the NOAA Ship Whiting and its launches 1005/1014. Multibeam bathymetric data were acquired with a Reson SeaBat 8101 and sidescan sonar backscatter data were acquired with Edgetech model 272-T (100 kHz) or the Klein T-5500 (455 kHz) sonar systems.
Process_Step:
Process_Description:
A hull-mounted Reson SeaBat 8101 acquired the shallow-water multibeam data for all four surveys. The Reson 8101 was operated at a frequency of 240 kHz and a maximum speed of 6 knots. The system is designed for operation in water depths of 5 to 125 m, and has a horizontal range of 75 to 500 m that depends on water depth. Each time the system fires or "pings", it collects 101 individual soundings in a swath oriented perpendicular to the vessel track. Acquisition was monitored in real time with the ISIS software (version 5.29) and recorded to XTF format. NOAA Office of Coast Survey converted the XTF data to Caris HDCS (Hydrographic Data Cleaning System) format, then processed and tide-corrected the data with Caris HIPS (Hydrographic Information Processing System) software. The Caris HIPS database was transfered to the USGS/CZM in 2004 for use in this project.
Process_Step:
Process_Description:
Tide-corrected multibeam soundings were exported from Caris HIPS at a 2-meter grid interval for each of the survey areas and reformatted for input into the Swathed processing software (University of New Brunswick Ocean Mapping Group). The soundings were gridded using the ?weigh_grid? routine creating 2-meter bathymetry grids. The OMG grid format (.r4) was converted to ASCII raster format.
