Approximately 170 kmĀ² of sidescan sonar data were collected by the National Oceanic and Atmospheric Administration (NOAA) Ship Whiting in 2000 and 2001 and reprocessed by the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS). 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.

Positional_Accuracy: 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.

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: Sidescan data were acquired by NOAA NOS with the Edgetech model 272-T (100 kHz) or the Klein T-5500 (455 kHz) sidescan sonar systems. Equipment was either hull mounted or towed. Range, layback, gain and other acquisition parameters varied and were adjusted accordingly in the acquisition software. Raw .xtf sonar files were transfered from NOAA NOS to the USGS/CZM. Process_Date: unknown Process_Step: Process_Description: The raw sidescan-sonar data were processed using XSonar/ShowImage software. The processing steps included demultiplexing the raw sidescan data using a median filtering routine to suppress speckle noise, a file check of navigation points to delete repeated fixes or other logging errors, correct for slant-range distortion, signal attenuation, and dropped sonar lines (Danforth, W.W., 1997, Xsonar/ShowImage: A complete system for rapid sidescan-sonar processing and display: U.S. Geological Survey Open File Report 97-686, 77 p.).

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 source information was incomplete and had to be modified to meet the standard. Removed the raster object information. Minor fixes to the attribute format for some attributes were needed. Removed an invalid link from the distribution section. 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.
