Glomb 2007 1.0 Open-File Report 2007-1138 Reston, VA U.S. Geological Survey http://pubs.usgs.gov/of/2007/1138/ 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.

The original multibeam bathymetric data acquired with a Reson 8125 and 8101 echosounder systems during NOAA survey H11079 aboard the NOAA ship Thomas Jefferson. The multibeam data was acquired in XTF (extended Triton data format), recorded digitally through an ISIS data acquisition system, and processed using CARIS HIPS (Hydrographic Image Processing System) software for quality control, to incorporate sound velocity and tidal corrections, and to produce a base surface at 3-m resolution. Among other formats (e.g. .tif and .gutm), the data were exported in text (.txt) format in UTM Zone 19. 2004 h11079_3mutm19_xyz.txt Marc Moser National Oceanic and Atmospheric Administration Field Operations Officer mailing address

Woods Hole MA 02543 508-548-8700 (x2315) 508-457-2310 sackerman@usgs.gov 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. Empty elements were deleted. The distribution format was modified in an attempt to be more consistent with other metadata files of the same data format. 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. 20151117 U.S. Geological Survey VeeAnn A. Cross Marine Geologist mailing and physical address
