Bathymetry, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities off southern New England, shows the character and terrain of the seabed, and provides information on sediment transport and benthic habitat. During April-May 2009 NOAA completed hydrographic survey H12007 in the vicinity of Cross Rip Channel in Nantucket Sound off southern Cape Cod, Massachusetts and during June 2011 bottom photographs and surficial sediment data were acquired as part of ground-truth reconnaissance surveys of this area. Interpretations were derived from the multibeam echo-sounder data and the ground-truth data used to verify them. The purpose of this data set is to release the locations, identifiers, grain-size data and(or) textural descriptions of surficial sediments collected at 24 stations on bathymetric data of the sea floor in the vicinity of Cross Rip Channel in Nantucket Sound, offshore southeastern Massachusetts in Geographic, WGS84. These data can be used to provide information on surface geology and sedimentary processes. 20110613 ground condition Complete None planned -70.298833 -70.231333 41.458833 41.440717 USGS Metadata Identifier USGS:ec8bc878-683c-423b-9d4c-47f43919d8ed None U.S. Geological Survey USGS Woods Hole Coastal and Marine Science Center WHCMSC Coastal and Marine Geology Program CMGP RV Rafael ESRI point Shapefile surficial sediment classification sediment data sediments sediment samples ground-truth gravel sand stations sea floor Field Activity Number 2011-006-FA Van Veen grab sampler SEABOSS Open-File Report 2011-1222 OFR 2011-1222 http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2011-006-FA gravelly sediment 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 Nantucket Sound Massachusetts Cape Cod Martha's Vineyard Nantucket Island Cross Rip Shoal Cross Rip Channel Horseshoe Shoal Halfmoon Shoal 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 in Nantucket Sound during the RV Rafael cruise 2011-006-FA are included in this data set. Stations range from CR1 to CR24. Navigation was by differential GPS. Although GPS gave the ships' positions rather than that of the SEABOSS, the antenna was located less than 5 m from the blocks on the davit and 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 were measured by the ship's fathometer, are provided are in meters, and are uncorrected for tides.

The source information was incomplete and had to be modified to meet the standard. Fourteen 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 10 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.

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. 20151216 U.S. Geological Survey VeeAnn A. Cross Marine Geologist mailing and physical address
