S. Geological Survey Open-File Report OFR 00-304 Woods Hole Field Center, Woods Hole, MA U. S. Geological Survey Valerie F. Paskevich and Lawrenc J. Poppe are the editors of the publication which contains 12 individual chapters with various authors. https://doi.org/10.3133/ofr00304 https://pubs.usgs.gov/of/2000/of00-304/ This tabular data contains a summary of the surficial sample locations, metal concentrations, Clostridium perfringens spores and information regarding sedimentary environments and sidescan sonar from Long Island Sound. The purpose of this datalayer is to disseminate a table that contains a summary of the surficial sample locations, metal concentrations, Clostridium perfringens spores and information regarding sedimentary environments and sidescan sonar from Long Island Sound. No CSDGM metadata originally accompanied this dataset, just a data dictionary. This metadata file was compiled based on information in Chapter 6 of the Larger Work Citation and the data dictionary published with the dataset. 1996 2000 sample collection years Complete None planned -73.74664 -72.043358 41.31031667 40.86602 USGS Metadata Identifier USGS:e6de1fa2-02b2-4df0-b4a4-3a8dd05f62ba 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 Excel spreadsheet 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 Clostridium perfringens spores 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.

Navigation for sample stations was done with differential GPS. Accuracy is assumed to be +/-10m. +/-10 m Typical accuracy for DGPS Based on information from the lisgrabs metadata in the same chapter of this report. No additional checks for topological consistency were performed on this data set. none Based on information from the lisgrabs metadata in the same chapter of this report. Navigation was by Differential GPS, which is accurate to less than 10 m. Typical accuracy for differential GPS navigation. Based on information from the lisgrabs metadata in the same chapter of this report. Vertical accuracy is +/-2m. Tidal range in LIS is less than 2 m The dataset was released in the publication without a CSDGM metadata file, only a data dictionary. The information in the data dictionary was reformatted to enable conversion to the entity and attribute section using an online data dictionary conversion service (https://mrdata.usgs.gov/validation/eainfo.php). The ranges of values and domain definitions were added based on the data itself. The data dictionary contained the column headings and definitions. The rest of the metadata is primarily from the lisgrabs metadata available from the same chapter (Chapter 6) of the larger work citation. Elements in the metadata included from the other metadata file, but assumed to apply to these data, are prefaced by "Based on information from the lisgrabs metadata in the same chapter of this report." See the report for additional information in how the data were handled. For the imported metadata information 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. 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 was edited to reflect the date of these changes. The metadata contact reflects the person who generated the CSDGM metadata file. 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. (20230626) 20230626 U.S. Geological Survey VeeAnn A. Cross Marine Geologist mailing and physical address

Some fields containing numeric values are defined as text because a field contains multiple numeric values separated by a comma.
