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 -71.441192 -71.161483 41.766614 41.433918 USGS Metadata Identifier USGS:d142ea74-498a-4c6a-b84b-31ed691ad9ec None U.S. Geological Survey Coastal and Marine Geology Coastal and Marine Geology Program Woods Hole Science Center GIS sediment gravel sand silt clay texture National Assessment of Marine Sand and Gravel Resources Open-File Report 2006-1199 CMGP sediment classification surficial classification shapefile points Geographic Information System ISO 19115 Topic Category oceans geoscientificInformation USGS Thesaurus grain-size analysis navigational data geospatial datasets sea-floor characteristics marine geology None U.S. East Coast Narragansett Bay New England Atlantic Rhode Island Providence, RI Mount Hope Bay Greenwich Bay None None Lawrence J.

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 2.9.36 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. Added ISO 19115 Topic Category keywords. Moved the vertical accuracy quantitative information to the qualitative accuracy report. 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. 20170213 U.S. Geological Survey VeeAnn A. Cross Marine Geologist Mailing and Physical
