Identifier 2002-020-FA
Purpose Characterize the lake floor and map sediment thickness using sidescan sonar and chirp sub-bottom profiling techniques.
Location Lake Mohave, Nevada, Arizona, United States, North America;
Summary A total of 223 km of 3.5 kHz Chirp sub-bottom and EdgeTech DF-1000 sidescan sonar data were collected. Navigation was with P-code DGPS.
