Lake Louisa Seismic Profiles


Home | Acronyms | Contents | Navigation | Profiles | Logs | Metadata | Software


Below are thumbnail images of each line with links to full-size printable and geospatial seismic reflection profiles. The printable profiles are GIF images that were filtered and 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 exported to CTI SonarWeb software to produce geospatial profiles that allow the user to obtain a geographic location and depth for a cursor position on the profile. This information is displayed in the status bar of the browser. The geospatial profiles, which are stored in the INTERACTIVE folder, have been corrected for the offset between the shotpoint and GPS antenna (fig. 1).

The Lake Louisa map shows the locations of the geospatial and printable profiles presented below.

Table 2 lists trackline statistics for 08LCA04.

NOTE: The only supported Web browsers that properly display all features of the geospatial profiles are Internet Explorer 6 or greater for Windows and Firefox 1.5 or greater for all platforms. 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 geospatial 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 Options.

If using Internet Explorer 7, Active Content/ActiveX controls must be disabled. Instructions for doing this can be found by clicking on the "details and setup" link on the geospatial profile pages.
