Frequently-anticipated questions:

What does this data set describe?
    Title: Smith, 1996
    Abstract:
    Recent, severe and persistent erosion along the New Jersey coastline has led to the development of shoreline remediation plans which require the emplacement of large volumes of beach quality sand at the shoreface. To meet the enormous demand for beach quality sediment, nearshore detached sand ridges are investigated to characterize their physical suitability for beach remediation. Analysis of 303 km of seismic reflection (GEOPULSE) profiles and twenty Vibracores (1-6 m) on the inner shelf off of Avalon, New Jersey documents five distinct lithologies which comprise two unconformity bounded units. The lithologies, in relative temporal order, are interpreted as: 1) Pleistocene lake and estuarine facies; 2) Pleistocene fluvial channel facies; 3) Holocene estuarine facies; 4) tidal ravinement channel facies; and 5) inner shelf sand ridge facies.

    The two unconformity bounded sequences are separated from one another in seismic section by a regional unconformity. The inner shelf sand ridge facies is part of the upper sequence and forms the topographic linear ridge systems. Three large sand ridges are identified through seismic analysis, two of which are considered to be of potential economic importance based upon their location, sediment characteristics and volume estimates. The Inner Sand Ridge contains an estimated 37 million cubic meters of usable sediment. Wood fragments dated at greater than 42 ka were recovered from the lower sequence below the regional unconformity.

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

      • Entity point (291)

    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 0.000001. Longitudes are given to the nearest 0.000001. 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.
