Description:
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 Great Round Shoal Channel, a passage through the shoals at the eastern entrance to Nantucket Sound, off Cape Cod, Massachusetts. In June 2006, bottom photographs and surficial sediment data were acquired as part of a ground-truth reconaissance survey.
Purpose:
To release a GeoTIFF image of the 1-meter, 100-kHz sidescan sonar data generated during NOAA survey H11079 in Great Round Shoal Channel, offshore Massachusetts, in geographic.

The original sidescan sonar data acquired with Klein 5250 echosounders during NOAA survey H11079 aboard the NOAA ship Thomas Jefferson.
Process_Step:
Process_Description:
The sidescan sonar data was acquired with 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 degrees 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.
