Description:

Abstract:

Lake Mohave is one of several multi-purpose reservoirs that have been constructed on the Colorado River. The lake was formed upon completion of the Davis Dam in 1953. No mapping of the floor of the lake had been conducted since completion of the Davis Dam. The U.S. Geological Survey, in cooperation with researchers form the University of Nevada Las Vegas, completed a geophysical survey of this lake in April 2002. The survey included collection of sidescan sonar imagery of nearly the entire lake floor, and high-resolution seismic-reflection profiles along widely spaced lines throughout the lake. The detailed mapping of the lake floor was used to determine the amount of sediment that had accumulated in the lake since impoundment, its distribution, and the processes of deposition.

Purpose:

This shapefile is used to enable correlation between seismic-reflection profiles and the sidescan-sonar imagery, geologic interpretation, and other features represented on the lake floor.

Horizontal_Positional_Accuracy_Report:

Navigation data were collected with a PLGR system. The nominal accuracy of the system is thought to be 10m. Since the Knudsen system is a sidemount rather than towed system, this accuracy is not diminished. Assumed accuracy is 10 meters.

Process_Step:

Process_Description:

This particular seismic data was acquired with a Knudsen chirp subbottom system with the data stored digitally on a laptop computer running the Knudsen system software. The navigation is stored in a separate file from the seismic SEG-Y data.

Process_Step:

Process_Description:

The Knudsen system does not necessarily start each seismic file with shot 1. Since the SEG-Y data files were being processed so that each file started with shot 1, these navigation files needed to have the same correction. This way the shotpoint navigation will correspond to the plotted SEG-Y data.

The shot point navigation for each line of seismic data was combined into a single file and then run through an AWK script which kept the first and last point of each line, and every shotpoint evenly divisible by 100.

The files were edited such that the day and julian day accurately represented the UTC timing of these events. In some cases, when the navigation system acquires data past midnight, the day and julian day were not updated.

Process_Description:

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.). Attempted to modify http to https where appropriate. Modified the data citation to add series and publication information, as well as include a landing page link. Moved the horizontal quantitative accuracy information to the horizontal accuracy report. Added the standard order process section, which includes a link to 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.
