Geological Survey 1 CD-ROM http://pubs.usgs.gov/of/2003/of03-001/ These data were collected by the National Ocean Service (NOS, formerly the U.S. Coast and Geodetic Survey) for the purpose of charting the coastal waters and navigable waterways of the United States. Data collected prior to 1965 were digitized from the final survey plots. All other data were digitized in the field during the surveys. These data were supplied by the National Geophysical Data Center (NGDC). This data set contains fields that are only a subset of those fields available in the NOS Hydrographic Database, but included in this data set are the NOS cartographic codes for bottom characteristics. Although included here, these codes are no longer customarily supplied by NGDC with the NOS Hydrographic Database. As such, this data layer provides important information that is no longer readily available. The purpose of this data layer is to provide the NOS cartographic codes for bottom character in a form that can be used to interpret surficial sediment distributions off the northeastern United States. 1869 1985 ground condition Complete None planned -73.947360 -66.049140 44.703360 40.002150 USGS Metadata Identifier USGS:98639959-1757-4e35-a98e-9256a8a5d247 None U.S. Geological Survey USGS Coastal and Marine Geology Program CMGP Woods Hole Science Center WHSC National Ocean Survey NOS National Geophysical Data Center NGDC NOS Hydrographic Database Cartographic Codes Rocky Sand Mud Pebbles Gravel Coarse Medium Fine Open-File Report 03-001 surficial sediments sediment classification surficial classification point shapefile points GIS ISO 19115 Topic Category oceans location geoscientificInformation USGS Thesaurus navigational data geospatial datasets sea-floor characteristics marine geology None Gulf of Maine Georges Bank Continental Shelf Offshore Southeastern New England Maine New Hampshire Massachusetts Rhode Island 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. This data set contains fields that are only a subset of those fields available in the NOS Hydrographic Database. This data set contains station locations, survey year, the original cartographic codes, and their verbal equivalents for 26129 stations. No information on navigational methods was provided with this data set. Based on the long period of data collection, navigation must have been by several methods. Navigational accuracy is unknown.

Information unavailable from original metadata. Cartographic codes were matched with their verbal equivalents in Microsoft Excel and, together with navigation and survey identifiers, were saved as an ASCII text file. The ASCII text file was imported to an ArcView table. The table was later converted to an event theme in ArcView and saved as the final shapefile. nosgom.txt 20020912 nosgom.shp nosgom.dbf nosgom.shx Lawrence J.

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
