    Title:
    Jones and Schubel, 1980: Distributions of surficial sediment and eelgrass in Great South Bay, New York (from Smith Point, West to Wantagh State Parkway)
    Abstract:
    The objectives of this study were to map the texture of the surficial sediments, their organic content, and the distribution of eelgrass. This report summarizes the data in tabular form (Appendix 1) and on a series of maps (packet). Tabulated data are presented as percent (by mass) of gravel (> 2.0 mm), sand (> 62.5 um, (silt (> 3.9 um>, clay (<3.9 um), shell fragments and organic carbon content for each sample. A station location map and contour maps of percent (by mass) silt plus clay, organic carbon, depth and eelgrass have been prepared and are located in a packet at the end of the report.

  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 (582)

    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.
