Brennan 2008 1.0 Open-File Report 2008-1004 Reston, VA U.S. Geological Survey 1 DVD-ROM http://pubs.usgs.gov/of/2008/1004/ 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, provides a fundamental framework for research and management activities along this part of the Massachusetts coastline, shows the composition and terrain of the seabed, and provides 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 Woods Hole, a passage between the Elizabeth Islands and Cape Cod, Massachusetts. In November 2007, bottom photographs, seismic-reflection profiles, and surficial sediment data were acquired as part of a ground-truth reconnaissance survey.

The original sidescan sonar data acquired with Klein T-5000 echosounders during NOAA survey H11077 aboard the NOAA ship Whiting. The sidescan-sonar data were acquired with a Klein T-5000 sidescan-sonar system hull mounter to a 29' aluminum launch deployed from the NOAA ship Whiting. The system was set to sweep 100 m to either side of the launch tracks. The sonar system emits two (port and starboard) 50°-wide beams tilted down 20° from horizontal, 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 0.5-m horizontal resolution. As part of this process, the sidescan-sonar data were demultiplexed and filtered to remove speckle noise and 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.

Woods Hole MA 02543-1598 508-548-8700 x2314 508-457-2310 lpoppe@usgs.gov Edits to the metadata were made to fix any errors that MP v 2.9.32 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 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. 20160603 U.S. Geological Survey VeeAnn A. Cross Marine Geologist mailing and physical address
