Brennan 2008 1.0 Open-File Report 2008-1004 Reston, VA U.S. Geological Survey 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.

Assumed to be NOAA. unknown DVD-ROM 20010905 20010909 ground condition Information unavailable from original metadata. Original processed multibeam bathymetric data. The multibeam data were acquired in XTF (extended Triton data format) and recorded digitally through an ISIS data acquisition system. A Reson 8101 echosounder hull-mounted on a 29' launch deployed from the NOAA ship Whiting was used to acquire the sounding data. These data were processed using CARIS HIPS (Hydrographic Image Processing System) software for quality control, and to incorporate sound velocity and tidal corrections. Sound velocity corrections were derived using frequent SEACAT CTD (conductivity-temperature-depth) profiles. Typically, a CTD cast was conducted every four to six hours of multibeam acquisition. Tidal zone corrections were calculated from data acquired at the Nantucket tidal gauge. The vertical resolution of the multibeam data is approximately 0.5% of the water depth. The data were gridded to 0.5-m resolution and exported in text (.txt) format. Vertical datum is mean lower low water; X and Y units are meters; UTM Zone 19, NAD83.

Woods Hole MA 02543 USA 508-548-8700 x2277 508-457-2310 kmcmullen@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 source information was incomplete and had to be modified to meet the standard. The distribution format name 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. 20160603 U.S. Geological Survey VeeAnn A. Cross Marine Geologist mailing and physical address
