Parker 2013 1.0 Open-File Report 2013-1003 Reston, VA U.S. Geological Survey DVD-ROM http://pubs.usgs.gov/of/2013/1003/ The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), is producing detailed geologic maps of the coastal sea floor. Bathymetric and sidescan-sonar data, originally collected by NOAA for charting purposes, provide a fundamental framework for research and management activities along this part of Block Island Sound, show the composition and terrain of the seabed, and provide information on sediment transport and benthic habitat. During June 2012, bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey of this area. Interpretations were derived from the multibeam-echosounder, sidescan-sonar, sedimentary, and photographic data collected in Block Island Sound. For more information on the ground-truth survey see <http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2012-002-FA>.

All collected data were processed and used to produce this dataset. Navigation was by differential GPS using Trimble DSM212L DGPS receivers (accurate to <1m). CARIS HIPS was used to process bathymetry data including correcting for vessel offset. The vertical resolution of the bathymetry data is approximately 0.5% of the water depth. Although there are no depth attributes associated with the GeoTIFF image, pixel values convey RGB values of individual cells. Warmer colors (e.g. red) are shallower depths; cooler colors are deeper.

Original processed multibeam bathymetric data. Bathymetric data were acquired in extended Triton data format (XTF) and recorded digitally through an ISIS data acquisition system. A RESON 7125, hull-mounted on the NOAA ship Thomas Jefferson and one 8.5-m launch and a RESON 8125 multibeam echosounder, mounted on another 8.5-m launch deployed from the NOAA ship Thomas Jefferson, were used to acquire the sounding data. All positioning and attitude were determined with Trimble DSM212L DGPS receivers and Applanix POS/MV Model 320 v.4 inertial navigation systems. The 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 three to four hours of multibeam acquisition. Tidal zone corrections were calculated from data acquired at the Newport, Rhode Island, New London, Connecticut, and Montauk, New York tidal gauges. The vertical resolution of the multibeam data is approximately 0.5% of the water depth. The data were gridded to 2-m resolution and saved as a CARIS HIPS database. Vertical datum is mean lower low water; X and Y units are meters; UTM Zone 19, NAD83. 2011 CARIS HIPS database National Oceanic and Atmospheric Administration Jasper Schaer Field Operations Officer mailing address

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 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. 20151207 U.S. Geological Survey VeeAnn A. Cross Marine Geologist mailing and physical address
