Title:
JPEG image of Seismic-Reflection Profiles Collected in the Pulley Ridge Study 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.

  4. Does the data set describe conditions during a particular time period?

    Beginning_Date: 29-Jun-1996
    Ending_Date: 11-Sep-2001
    Currentness_Reference: ground condition

  5. What is the general form of this data set?

    Geospatial_Data_Presentation_Form: remote-sensing image

  6. How does the data set represent geographic features?

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

      This is a Raster data set. It contains the following raster data types:

      • Dimensions 1219 x 6205 x 1, type Pixel

    2. What coordinate system is used to represent geographic features?

      Planar coordinates are encoded using row and column
      Abscissae (x-coordinates) are specified to the nearest 1.000000
      Ordinates (y-coordinates) are specified to the nearest 1.000000

  7. How does the data set describe geographic features?

    Entity_and_Attribute_Overview:
    These images are intended only as previews of the seismic-reflection data. In each image, the x-axis represents shot point and the y-axis is two-way travel time in seconds. Although these images are not georeferenced, the images can be related to the seismic tracklines and shotpoint navigation which are both available in shapefile format.

Why was the data set created?

These images of the seismic-reflection profiles are provided so that individual can view the seismic data without the requirement of special software.

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 2)
    Seismic data were collected in 1996 (lines 47 and 48) and 2001 (line 23-32 and line 34). The 1996 data were collected with an ORE boomer sled, Geopulse power supply (operating at 375 Joules), an ITI streamer, and logged onto an Elics acquisition system. Navigation was acquired with a DGPS system. The data collected in 2001 were collected with a Huntec boomer sled, Applied Acoustics power supply (operating at 375 Joules), an ITI streamer, and logged onto an Elics acquisition system. Navigation was acquired with a DGPS system.

    (process 2 of 2)
    The SEG-Y files were processed and converted to JPEG images using SeismicUnix software.
