Title:
Seismic Trackline Navigation: USF navigation of seismic data collected in the Pulley Ridge area
Abstract:
These seismic data were collected to infer the paleodepositional environment of Pulley Ridge through seismic facies analysis. Without actual rock cores, remote sensing is the next best tool. It was uncertain if Pulley Ridge represented a drowned reef or paleoshoreline. Through seismic imaging, it was determined from the high-amplitude, level-bedded nature of material in the sub-surface that Pulley Ridge represents several stages of barrier-island development.

  6. How does the data set represent geographic features?

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

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

      • String (13)

    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 1983.
      The ellipsoid used is Geodetic Reference System 80.
      The semi-major axis of the ellipsoid used is 6378137.000000.
      The flattening of the ellipsoid used is 1/298.257222.

    Entity_and_Attribute_Overview:
    Lines 47 and 48 were collected in 1996, the remainder of the seismic lines (23-32 and 34) were collected in 2001. The 1996 seismic data were collected with ORE boomer sled, Geopulse power supply (375 joules), ITI streamer, Elics acquisition and processing software, and DGPS. The 2001 seismic data were collected with Huntec boomer sled, Applied Acoustics power supply (375 joules), ITI streamer, Elics acquisition and processing software, and DGPS.

Why was the data set created?

This GIS layer is provided to enable a correlation between seismic-reflection profile images and their geographic location based on shotpoints.

How was the data set created?

  1. From what previous works were the data drawn?

  2. How were the data generated, processed, and modified?

    (process 1 of 4)
    Navigation was acquired from USF (University of South Florida) in a format suitable for import into an Excel spreadsheet with shotpoint navigation for each seismic line in a separate file.

    (process 2 of 4)
    The individual navigation files were export from excel in to a comma delimited format.

    (508) 457-2310 (FAX)
    vatnipp@usgs.gov

    (process 3 of 4)
    These individual navigation files were then concatenated together into one file and imported to ArcView as an ESRI ungenerate format and converted to a shapefile.

    (process 4 of 4)
    The "hotlink" attribute field was added so that the tracklines could be linked to the JPEG images of the seismic-reflection profiles.
