Geological Survey Data is released via CD-ROM media. This digital publication may also be available via the web at pubs.usgs.gov http://pubs.usgs.gov/of/2003/of03-001 Gravel, sand, silt, and clay contents were determined for samples from Narragansett Bay and the adjacent Rhode Island Shelf. In the Narragansett Bay system, clayey silt and sand-silt-clay are the most abundant sediments. Sand is abundant locally and on the inner shelf. In general, toward the lower passages of the Bay the sediments show a progressive change to coarser textures. The purpose of this data layer is to release a digital version of the sediment data used in the interpretations published by McMaster (1960). 1960 publication date Complete None planned -71.441700 -71.162000 41.766700 41.434000 USGS Metadata Identifier USGS:644d04d3-07c5-4fd2-8f42-6dd9271f6d84 None U.S. Geological Survey USGS Coastal and Marine Geology Program CMGP Woods Hole Science Center WHSC GIS sediment gravel sand silt clay texture National Assessment of Marine Sand and Gravel Resources Open-File Report 03-001 sediment classification surficial classification point shapefile points Geographic Information System ISO 19115 Topic Category oceans location geoscientificInformation USGS Thesaurus grain-size analysis navigational data geospatial datasets sea-floor characteristics marine geology None Narragansett Bay Rhode Island Providence, RI Mount Hope Bay Greenwich Bay New England U.S. East Coast Atlantic Ocean None Public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution.

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. Minor fixes to the attribute format for some attributes was needed. 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. 20151202 U.S. Geological Survey VeeAnn A. Cross Marine Geologist mailing and physical address
