U.S. Geological Survey Data Series 242
Below are thumbnail images of each line with links to full-size printable and interactive seismic reflection profiles. The printable profiles are GIF images that were gained using Seismic Unix software. These images are stored in the PRINTABLE folder. Refer to the Software page for details about the processing and examples of the processing scripts.
The processed SEG-Y data were then exported to CTI SonarWeb software to produce interactive versions of the profiles that allow the user to obtain a geographic location and depth from the profile for a cursor position. This information is displayed in the status bar of the browser. The interactive profiles, which are stored in the INTERACTIVE folder, have been corrected for the offset between the shotpoint and GPS antenna (see fig. 1).
Note: The Web version of this archive does not contain the SEG-Y Trace files. These files are very large and would require extremely long download times. To obtain the complete DVD archive, contact USGS Information Services at 1-888-ASK-USGS.
NOTE: Although data were collected in UTM Zones 15 and 16, all equipment and data processing were set to Zone 15 for this cruise.
Warning! The only supported Web browsers that properly display all features of the interactive profiles are Internet Explorer 6 for Windows and Firefox 1.5 for all platforms. Caution–use of other browsers may result in spurious or no information given in the status window. Firefox may be downloaded at http://www.mozilla.org/products/firefox.
Browser setup for viewing interactive profiles:
For all browsers, the status bar and JavaScript must be enabled. Firefox also requires "Change status bar text" to be checked under Advanced JavaScript Settings.
Table 2 lists trackline statistics for 05SCC01.
NOTE: Depths shown are relative to the depth of the towfish, not to sea level
NOTE: Disc 1 contains SEG-Y files for lines 05c01_a through 05c13_b, and disc 2 contains SEG-Y files for lines 05c14 through 05c21.
