Title:
Composite Grayscale Image of the Sidescan Sonar Data From National Oceanic and Atmospheric Administration (NOAA) Survey H11076 of the Sea Floor in Quicks Hole, MA (H11076_GEO_1MSSS.TIF, Geographic)
Abstract:
The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and the Massachusetts Office of Coastal Zone Management (MA CZM), is producing detailed geologic maps of the coastal sea floor. Imagery, originally collected by NOAA for charting purposes, provide a fundamental framework for research and management activities along this part of the Massachusetts coastline, show the composition and terrain of the seabed, and provide information on sediment transport and benthic habitat. Interpretive data layers were derived from multibeam echo-sounder and sidescan sonar data collected in the vicinity of Quicks Hole, a passage through the Elizabeth Islands that extend in a chain southwestward off Cape Cod, Massachusetts. In June 2005, bottom photographs and surficial sediment data were acquired as part of a ground-truth reconaissance survey.

Why was the data set created?

To release a GeoTIFF of the 100-kHz sidescan sonar data generated during National Oceanic and Atmospheric Administration (NOAA) survey H11076 in Quicks Hole, Elizabeth Islands, Massachusetts, in geographic.

How was the data set created?

  1. From what previous works were the data drawn?

    Source_Contribution:

  2. How were the data generated, processed, and modified?
    Date: Unknown (process 1 of 5)
    The sidescan sonar data was acquired with a Klein 5250 sidescan sonar tow fish set to sweep 100 m to either side of the launch tracks. The tow fish emits two 50-degree-wide beams tilted down 20-degree from horizontal, and transmits at 100 kHz. The data were acquired in XTF (extended Triton data format), recorded digitally through an ISIS data acquisition system, and processed using CARIS SIPS (Sidescan Image Processing) software for quality control, and to produce an image at 1-m resolution. As part of this process, the sidescan-sonar data were multiplexed and filtered to convert the data into the desired processing format and to remove speckle noise and to correct for slant-range distortions. Image 'shine through', to account for areas of overlap, and auto-contrast adjustment were applied. Tonal artifacts caused by inaccurate across-track normalization present on the sidescan-sonar imagery are minor. Contrast enhancement based on the dynamic range of the data was applied to the mosaic and it was then projected into UTM Zone 19 to produce the final enhanced image.

    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. 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. Only the source media, time period of content, and source contribution were supplied. The geodetic model needed information added to meet the standard. 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. Person who carried out this activity:
