Title:
Interpretation of the New York Bight Fault Zone on the inner-continental shelf within the New York Bight, derived from seismic data collected by the U.S. Geological Survey, 1995 - 1999 (Esri polyline shapefile, Geographic, WGS84)
Abstract:
The New York Bight fault (Hutchinson, 1984) was clearly evident within the high-resolution seismic records acquired with a CHIRP, boomer, and 15 cubic inch water gun systems. This fault was mapped from these data. Thus, yeilding a more complete picture of the inner-shelf geologic framework of the area.

Why was the data set created?

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.

  2. How were the data generated, processed, and modified?
    Date: 2000 (process 1 of 6)
    As part of the MS Thesis, the location of the New York Bight fault was mapped from high-resolution seismic records (15 cubic inch water-gun). The location of the fault was saved as a digital ASCII file listing x,y (eastings and northings). The coordinates were transformed from UTM, Zone18, WGS84 to Geographic, Coordinate System, WGS84 datum. These ASCII x,y data were imported into ArcView 3.2 as a table. They were then coverted into an ESRI point shapefile. Person who carried out this activity:

    Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Completely changed the title based on an author (Jane Denny) supplied title. Added online links to the publication and data page in the Identification section. Added the standard order section to the Distribution Information, which included providing a link to download the data. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. 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. Person who carried out this activity:

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    These data are derived from 2D seismic reflection profiles that are spaced approximately 1.3 km apart in the cross track-direction. Shore perpendicular track lines were spaced about 3-4 km apart. Along track samples of the seismic profiles are approximately 1 meter assuming a ship speed of 2 meters/second. The data were downsampled in the along-track direction at an interval of about 30 meters.
  2. How accurate are the geographic locations?
    DGPS is assumed to be accurate within 1-2 meters. Standard GPS is assumed accurate within 5-10 meters. 99% of the positional data is DGPS. Unless noted, all GPS/DGPS data is referenced to WGS84 (NAD83). The horizontal positioning did not account for source and receiver offsets and offset the GPS antennae and the boomer source and streamer. It is estimated that these offsets could lead to inaccuracies of about 30 m.
  3. How accurate are the heights or depths?
    Vertical positioning accuracy of the offshore data is based on the seafloor reference used.
  4. Where are the gaps in the data? What is missing?
    complete
  5. How consistent are the relationships among the observations, including topology?
    The New York Bight Fault was mapped from high-resolution CHIRP, boomer, and 15 cubic inch water gun seismic systems. These data were checked for consistency be comparing mapped locations to those reported in the literature (Hutchinson, 1984).
