Attribute information containing the chemical analysis values are also included in the data layer. The purpose of this datalayer is to disseminate a digital version of the map showing the locations of surficial samples used in the analysis of metal distributions in LIS. 1996 1997 sample collection Complete None planned -73.7469 -72.0420 41.3379 40.8363 USGS Metadata Identifier USGS:2b5e1830-fece-44bb-94f0-617e7f346be1 None U.S. Geological Survey USGS Coastal and Marine Geology Team Coastal and Marine Geology Program Woods Hole Field Center Connecticut Department of Environmental Protection ArcView arcview shapefile points surficial sediments metal distribution Ag silver Al aluminum Ba barium Ca calcium Cd cadmium Cr chromium Cu copper Fe iron Hg mercury Mn manganese Ni nickel Pb lead Ti titanium V vanadium Zn zinc Zr zirconium sedimentary environment USGS Thesaurus geospatial datasets unconsolidated deposits grab sampling aluminum barium calcium cadmium chromium copper iron mercury manganese nickel lead titanium vanadium zinc zirconium silver None Long Island Sound Connecticut New York None The U.S. Geological Survey must be referenced as the originator of the dataset in any future products or research derived from these data.

Freeze-dried samples were divided for various analyses. The metals data were generated on an ICP-AES at Boston University after total acid disestion. Data (consisting of the sample station navigation in decimal degrees and metals concentrations) were imported as a text file. LISgrabs Unknown LISgrabs U.S. Geological Survey Ellen L.

Woods Hole MA 02543-1598 USA (508) 548-8700 x2213 emecray@usgs.gov Edits to the metadata were made to fix any errors that MP v 2.9.50 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. Additional small edits including (but not limited to) such as adding the edition element were perfomed on the metadata. Author names were edited to remove "ed." and "comp". Added links to access the data including the DOI link. Added USGS Thesaurus keywords. Added keywords section with USGS persistent identifier as theme keyword (PID). Fixed the ellipsoid name to agree with the datum. Fixed the denominator of flattening ratio. Updated the distribution liability. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. A generic email in the metadata contact was used, along with adding contact instructions. 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.
