What does this data set describe?
    Title:
    USGS Open-File Report 00-304, Chapter 6, Long Island Sound - Metal Distributions in the Surface Sediments of Long Island Sound
    Abstract:
    This report chapter presents data, maps, and tables of metals in Long Island Sound surface samples collected in 1996-1997. This information is used to: (1) establish a regional baseline for temporal studies of contamination in Long Island Sound; (2) identify areas of high contamination in the Sound; (3) elucidate transport and deposition processes affecting contaminant distributions; and (4) generate predictive and assessment tools for regional management in Long Island Sound and elsewhere

  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):

      • Entity point (210)

    2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.

      The horizontal datum used is North American Datum of 1927.
      The ellipsoid used is Clarke 1866.
      The semi-major axis of the ellipsoid used is 6378206.400000.
      The flattening of the ellipsoid used is 1/294.978698.
