Summary Information for Field Activity 2001-007-FA

Area of Operations: Lake Mead, Nevada, Arizona, United States, North America

Dates: April 01, 2001 to April 26, 2001

Chief scientist: Dave Twichell

   Mark Rudin, UNLV

Objectives: Sidescan sonar and high-resolution seismic reflection mapping of Lake Mead to map the surficial geology of the lake floor and the thickness and distribution of post-impoundment sediment in the lake.

Type of Activity:

Information to be derived:

Summary: Sidescan sonar imagery and chirp sub-bottom profiles were collected along 955 km of survey tracklines. Data were collected along lines spaced 500-700 m apart and provided nearly complete sidescan coverage of the eastern two-thirds of the lake as well as a dense grid of sub-bottom profiles. Boomer sub-bottom profiles were collected along 96 km of tracks to provide deeper penetration in the areas of thick sediment cover.
