  Description:
    Abstract:
      The New York Department of Conservation well log data were utilized
      in correlating offshore geologic structures to those found
      onshore. This offered a more complete understanding of the stratigraphic
      evolution of the region.
    Purpose:
      In 1995, the U.S. Geological Survey (USGS), in cooperation
      with the U.S. Army Corps of Engineers (USACE), began a
      program to generate reconnaissance maps of the sea floor
      offshore of the New York - New Jersey metropolitan area and
      within the southern Long Island nearshoe area. Our methods
      include high-resolution sidescan sonar and subbottom
      profiling techniques, along with surface grab and vibracore
      sampling to verify the geophysical interpretations. The goal
      of the investigation is to provide a regional synthesis of
      the sea-floor environment, to determine regional-scale
      availability of sand as a resource for beach nourishment
      programs, and to investigate the role that inner-shelf
      morphology and geologic framework have in the evolution of
      the coastal region within the New York Bight Apex and
      southern Long Island. Maps derived from interpretation of
      the subbottom profiles show information on the geometry and
      distribution of the Quaternary sediments and the underlying
      coastal-plain unconformity. This seismic stratigraphy yields
      a regional framework on which explanations of present (and
      past) sediment movement, dispersal, and erosion processes
      are based.

  Logical_Consistency_Report:
    The location of the well log data and depth to the coastal-plain Unconformity
    were transcribed from paper descriptions. All transcriptions were performed by one
    individual.  All data were quality checked by analyzing position and depth to
    coastal-plain Unconformity in relation to adjacent well log locations and
    descriptions within the literature (Suter, 1949).

        Well log data acquired throughout Long Island were used to idenitify the
        depth to the coastal-plain Unconformity onshore.  These data were correlated
        to the offshore seismic records, creating a comprehensive view of onshore/offshore seismic structures.

        The well log data compiled within this thesis were used to generate
        a gridded data set of the depth to coastal-plain Unconformity and
        Quaternary thickness onshore Long Island, NY.
    Process_Step:
      Process_Description:
        As part of the MS Thesis, position of well logs onshore Long Island and description of
        well log data (i.e. depth to coastal-plain Unconformity) were transcribed from paper
        records and placed into digital form as ASCI x,y,z data. The well log data were stored
        within EarthVision as point data. These point data were exported from Earthvision
        (x,y,z). The coordinates were transformed from UTM, Zone18, WGS84 to Geographic,
        Coordinate System, WGS84 datum. The z value was stored in meters, and represents the depth
        to the coastal-plain Unconformity. These ASCII x,y,z data were imported into ArcView
        3.2 as a table. They were then coverted into an ESRI point shapefile. The only
        attributes associated with these data are z - depth to coastal-plain Unconformity.
