Imagery, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities along this part of Long Island Sound, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. Interpretive data layers were derived from the multibeam echo-sounder data and sidescan-sonar data collected north of Orient Point, New York. During April 2010, bottom photographs and surficial sediment data were acquired as part of a USGS ground-truth reconnaissance survey. For more information on the ground-truth survey see http://quashnet.er.usgs.gov/data/2010/10010/. Purpose: To release a GeoTIFF of the 1-m, 455-kHz sidescan-sonar data generated during NOAA survey H11446 in Long Island Sound, north of Orient Point, in UTM 18, NAD83 coordinate system.

Process_Step: Process_Description: The sidescan-sonar data were acquired with Klein 5000 sidescan-sonar system hull mounted to a 29' aluminum launch deployed from the NOAA ship Thomas Jefferson. The system was set to sweep 100 m to either side of the launch tracks. The system has a vertical beam angle of 40 degrees and transmits at 455 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 a composite sidescan-sonar image at 1-m horizontal resolution. As part of this process, the sidescan-sonar data were demultiplexed and filtered 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. Contrast enhancement based on the dynamic range of the data was applied to the mosaic and it was then projected into UTM Zone 18 to produce the final enhanced image.
