Parker 2014 1.0 Open-File Report 2014-1160 Reston, VA U.S. Geological Survey DVD-ROM https://doi.org/10.3133/ofr20141160 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 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 2013, 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, sedimentary, and photographic data collected in Block Island Sound. For more information on the ground-truth survey see https://cmgds.marine.usgs.gov/fan_info.php?fan=2013-005-FA. To release interpretations of sedimentary environments based on bathymetry data collected during NOAA survey H12299 and sediment samples and bottom photography collected during USGS survey 2013-005-FA in Block Island Sound in a geographic, WGS 84 coordinate system. 2014 publication date Complete None planned -72.103557 -71.853053 41.197399 41.120979 USGS Metadata Identifier USGS:885d7e1f-e75e-4fa2-88ab-a43dfc671ade None U.S. Geological Survey USGS Woods Hole Coastal and Marine Science Center Sedimentary environments Coastal and Marine Geology Program CMGP WHCMSC NOAA Survey H12299 H12299 National Oceanic and Atmospheric Administration NOAA Field Activity Number 2013-005-FA Esri shapefile Erosion or nondeposition polygon shapefile Info bank ID B-05-13-LI Coarse-grained bedload transport Sorting and reworking interpretation ISO 19115 Topic Category geoscientificInformation oceans USGS Thesaurus scientific interpretation sea-floor characteristics ocean processes sediment transport geospatial datasets None New York Block Island Sound U.S. East Coast United States North America Atlantic Ocean Gardiners Island None The interpretation of sedimentary environments was completed at map scales less than 1:10,000, and is not intended for use with smaller map scales.

All collected data within the study area were processed and used to produce this dataset. Navigation for the sediment samples and bathymetry data, which the sedimentary environments were based on, was by differential GPS. NOAA (assumed - not specified in original metadata) unknown DVD-ROM 20110912 20130620 ground condition Information unavailable in original metadata. The original acoustic data acquired during NOAA survey H12299 aboard the NOAA ship Thomas Jefferson were collected from Sept. 12, 2011 to Nov. 15, 2011 and the sediment samples and bottom photography were collected during USGS survey 2013-005-FA between June 18-20, 2013. The geographic GeoTIFF image of the multibeam data from survey H12299 and the point data layers from bottom photography and grain-size analyses of sediments collected from this survey area were imported into the ArcMap 9.3. Bottom features were interpreted based on the bathymetry, bottom photography, and textural analyses. The individually interpreted features (i.e. boulders) were outlined using the available graphic tools. This and all subsequent process steps were completed by the same person, Katherine McMullen. h12299_mb2m_geo.tif 2013-005_299seddata.shp 2013-005_299botphotos.shp 2014 h12299interp.shp Katherine McMullen U.S. Geological Survey Field and Laboratory Technician mailing and physical address

Woods Hole MA 02543-1598 508-548-8700 x2277 508-457-2310 kmcmullen@usgs.gov Sedimentary environments were interpreted largely based on the sea floor interpretations (h12299interp.shp). A shapefile was created in ArcCatalog 9.3 and interpretation polygons were merged with it. Boulders indicate environments of erosion or nondeposition, sand waves indicate coarse-grained bedload transport, and modern marine sediments are likely environments characterized by sorting and reworking. In areas where the interpretation polygons overlapped, the dominant feature on the sea floor was used. Polygons with overlap were intersected, clipped, and either merged with the dominant area or relabeled using the tools in ArcMap 9.3. In outlining the eastern border of the sedimentary environments in the H12299 area, we attempted to match those in the study area to the east (USGS Open-File Report 2012-1005), although those interpretations were done using 4-m bathymetry, so some features visible in the 2-m bathymetry of overlapping and adjacent areas in this survey were not discernable. Thus, the sedimentary environments do not necessarily match, particurlarly along the southeast side of this survey. h12299interp.shp 2014 h12299sedenv.shp Edits to the metadata were made to fix any errors that MP v 2.9.36 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.). Attempted to modify http to https where appropriate. Reordered the links in the identification section, and added the DOI link as the first link. Updated the link to the field activity. 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. 20171004 U.S. Geological Survey VeeAnn A. Cross Marine Geologist Mailing and Physical
