Geological Survey 1 CD-ROM http://pubs.usgs.gov/of/2003/of03-001/ A reconnaissance survey of that part of the Scotian Shelf extending from Halifax to Digby Nook was conducted during October, 1961, in order to determine the nature, distribution, and source areas of the bottom sediments. In general, the fine grained deposits of silt and clay (pelite) are found in the basins on the shelf as well as in the deeper water at the upper edge of the continental slope. Coarse grained deposits characterize topologically high areas and along the shelf margin. The purpose of this data layer is to provide a digital version of the sediment data published in Pezzetta (1962). 1962 publication date Complete None planned -67.817000 -61.300000 44.567000 41.750000 USGS Metadata Identifier USGS:79c2823c-45ee-49ce-b47a-cdf8741fd9f6 None U.S. Geological Survey USGS Coastal and Marine Geology Program CMGP Woods Hole Science Center WHSC sediment texture grain size gravel sand mud Open-File Report 03-001 sediment classification surficial classification point shapefile points GIS ISO 19115 Topic Category oceans location geoscientificInformation USGS Thesaurus grain-size analysis navigational data geospatial datasets sea-floor characteristics marine geology None Nova Scotian shelf Nova Scotia shelf Canadian East Coast continental shelf U.S. East Coast Atlantic Ocean None Public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution.

No additional checks for topological consistency were performed on this data. Sample locations, textural descriptions, grain size data, and identifiers are provided for 69 stations. Navigation was by several methods (Loran A, RADAR, Dead Reckoning). Navigational accuracy is unknown. J.M. Pezzetta 1962 1.0 Master's Thesis 104 p.

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 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
