Geological Survey 1 CD-ROM http://pubs.usgs.gov/of/2003/of03-001/ The Contaminated Sediments Database for the Gulf of Maine provides a compilation and synthesis of existing data to help establish the environmental status of our coastal sediments and the transport paths and fate of contaminants in this region. This information, in turn, forms one of the essential bases for developing successful remediation and resource management policies. The Contaminated Sediments Database for the Gulf of Maine provides a compilation and synthesis of existing data to help establish the environmental status of our coastal sediments and the transport paths and fate of contaminants in this region. This information, in turn, forms one of the essential bases for developing successful remediation and resource management policies This product is the result of a collaborative effort of principal investigators from the U.S. Geological Survey Coastal and Marine Geology Program, Woods Hole Oceanographic Institution, the University of New Hampshire, Bigelow Laboratory for Ocean Sciences, the University of Massachusetts, and active participation from the U.S. Army Corps of Engineers, the U.S. Environmental Protection Agency, the Massachusetts Water Resources Authority, the National Oceanic and Atmospheric Administration, and other federal and state agencies. Funding was provided by participating institutions and the Gulf of Maine Regional Marine Research Program. The purpose of this data layer is to release a subset of the Gulf of Maine Contaminated Sediments Database that can be used to interpret surficial sediment distribution off the northeastern U.S. 2002 publication date Complete None planned -71.100000 -67.335000 44.678000 40.400000 USGS Metadata Identifier USGS:96ad25a9-88c0-4e6c-81e0-a10d4331f820 None U.S. Geological Survey USGS Woods Hole Science Center sediment texture gravel sand silt clay mud class lithology Open-File Report 03-001 Coastal and Marine Geology Program CMGP sediment classification surficial classification point shapefile points GIS Geographic Information System WHSC ISO 19115 Topic Category oceans location geoscientificInformation USGS Thesaurus grain-size analysis navigational data geospatial datasets sea-floor characteristics marine geology None U.S. East Coast Maine New Hampshire Massachusetts Gulf of Maine Atlantic United States USA North America 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, grain-size data, textural classifications, and sample identifiers are provided for 852 stations. Navigation was by several methods; navigational accuracy unknown. M.R. Buchholtz ten Brink F.T. Manheim E.L. Mecray M.E. Hastings J.M. Currence J. Farrington S. Jones B. Tripp G. Wallace L. Ward T.

Textural and lithologic data from the Gulf of Maine were clipped from the whole Gulf of Maine Contaminated Sediments Database in Excel and exported to an ASCII file. Stations and sediment data were imported from the ASCII text file to an ArcView table. The table was later converted to an event theme and saved as the final shapefile. gomcsdb.txt 20021204 gomcsdb.shp gomcsdb.shx gomcsdb.shp 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 source information was incomplete and had to be modified to meet the standard. The attribute measurement resolution was changed from 0.00 (an invalid value) to 0.01 in the following attributes: GRAVEL, SAND, SILT, CLAY, and FINES. 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. 20151201 U.S. Geological Survey VeeAnn A. Cross Marine Geologist mailing and physical address
