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 from 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 sidescan-sonar imagery is used to map the morphology of the lake floor and determine the extent of sediment distribution on the lake floor.

Horizontal_Positional_Accuracy_Report:
The ship was navigated with a PLGR system with an assumed navigational accuracy of +/- 10m. Range to towfish was used to estimate the towfish position. Due to the inherent inaccuracies in this method, plus navigational smoothing and mosaicking issues, the accuracy is assumed to be closer to the 20-30m value.
Lineage:
Process_Step:
Process_Description:
Sidescan sonar imagery was collected using an Edgetech DF1000 sidescan sonar system and logged to a Triton QMIPS data logging computer. The data were collected at a 150m, 200m, 400m, or 600m swath, 1024 pixels/side, 16-bit. The digital sidescan data were then processed and mapped to provide proper geographic locations of features identified in the imagery. The processing steps included subsampling the raw sidescan data using a median filtering routine to suppress speckle noise and reduce file size, and correct for slant-range distortion, signal attenuation, and dropped sonar lines using XSonar (Danforth et al., 1991).

Process_Description:
The imagery was mapped into its proper geographic location using the XSonar software. Individual sidescan swaths were mapped with each pixel geographically positioned at a resolution of 2 m/pixel.
Process_Date: unknown
Process_Step:
Process_Description:
Non-overlapping swaths were then brought into the remote sensing software package PCI. The techniques for generating the composite digital sidescan mosaic are summarized by Paskevich (1996). The imagery portion was then cut out and written to a PCI channel with a white background. A LUT was applied to the imagery such that the image contains values 0-254. Because the background is 255, that color can be made transparent when viewing in a GIS.
Process_Date: unknown
Process_Step:
Process_Description:
The image was then exported from PCI as a geotiff image with an associated world file.
Process_Date: unknown
Process_Step:
Process_Description:
Because the original mosaicking was done in UTM, Zone 11, WGS84, the resulting TIFF image was then reprojected to the NAD83 datum using BlueMarble Geographic Transformer, version 5.0. This ensures that all the GIS data are in the same datum.

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. Fixed the cross-references format and added online links when appropriate. Moved the horizontal quantitative accuracy information to the horizontal accuracy report. Added the distribution format and link to the data in the standard order process section. 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.
