Doran 2011 1.0 Open-File Report 2010-1150 Reston, VA U.S. Geological Survey 1 DVD-ROM http://pubs.usgs.gov/of/2010/1150/ 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. Bathymetry and sidescan-sonar imagery, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities in Long Island Sound, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. During October 2008 NOAA completed hydrographic survey H11997 offshore in eastern Long Island Sound, and during May 2010 bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey of this area. Two interpretive data layers were derived from the multibeam echo-sounder and the ground-truth data used to verify them. For more information on the ground-truth survey see http://quashnet.er.usgs.gov/data/2010/10015/ The purpose of his data set is to release the locations, identifiers, grain-size data and(or) textural descriptions of surficial sediments collected at 28 stations on bathymetric data of the sea floor offshore in eastern Long Island Sound in Geographic, WGS84. These data can be used to provide information on surface geology and sedimentary processes. 20100524 20100526 ground condition Complete None planned -72.392433 -72.149967 41.241783 41.149400 USGS Metadata Identifier USGS:bd387404-b357-429a-b914-ad7df4b40c3e None U.S. Geological Survey USGS Woods Hole Coastal and Marine Science Center WHCMSC Coastal and Marine Geology Program CMGP OSV Bold ESRI point Shapefile surficial sediment classification sediment data sediments sediment samples ground-truth gravel sand silt stations sea floor Field Activity Number 2010-015-FA Van Veen grab sampler SEABOSS Open-File Report 2010-1150 OFR 2010-1150 http://quashnet.er.usgs.gov/data/2010/10015/ clay ISO 19115 Topic Category environment location oceans geoscientificInformation USGS Thesaurus grain-size analysis navigational data geospatial datasets sea-floor characteristics marine geology None northeast United States North America United States Atlantic Ocean Long Island Sound Connecticut New York None Public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution.

No additional checks for consistency were performed on this data. All available grain-size data collected within the study area during the OSV Bold cruise 2010-015-FA are included in this data set. Stations range from 997-1 to 997-28. Navigation was by differential GPS. Although GPS gave the ship's position rather than that of the SEABOSS, the antenna was located less than 5 m from the block on the A-frame, water depths were generally shallow, and scope of the cable minimal. Therefore, SEABOSS offset from the antenna was less than 10 m. Depths provided are in meters and are uncorrected for tides. The source information was incomplete and had to be modified to meet the standard. Assumed to be USGS. unknown computer program 20100524 20100526 ground condition The source information was incomplete and had to be modified to meet the standard. Information unavailable from original metadata. Nineteen samples were collected with a Van Veen grab sampler (Blackwood and Parolski, 2001) equipped with a still and video camera. Visual descriptions were used for rocky/bouldery stations at 9 additional stations where samples could not be collected. Samples were analyzed in the sediment laboratory at the USGS Woods Hole Science Center. Coarse fraction determined by sieve; fine fraction determined by Coulter Counter. See Poppe, Williams, and Paskevich (2005) for analytical specifics. 2010 2010_015_997seddata.txt Larry Poppe U.S. Geological Survey Geologist mailing and physical address

Woods Hole MA 02543-1598 USA 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 source information was incomplete and had to be modified to meet the standard. 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. 20160304 U.S. Geological Survey VeeAnn A. Cross Marine Geologist mailing and physical address
