Field Activity 2017-049-FA

Identifier 2017-049-FA
Purpose Collect multibeam bathymetry and sub-bottom data within Lake Powell and at the confluence of several rivers (Colorado, Escalante, San Juan)
Location Lake Powell, Utah
Summary Covered 331 square kilometers of Lake Powell UT/AZ using the R/V Stephens (23' SeaArk) owned by Utah Water Science Center, in Salt Lake, City. Collected bathymetry and backscatter data along 2407 kilometers of lines using a Dual-head Reson T20-P. Collected 92 kms of EdgeTech 424 data in the northeast portions of the lake at confluence of Colorado and San Juan Rivers.
Info derived Bathymetry, backscatter and sub-bottom data will be collected.
Comments Leg 1 (Worley, Baldwin, Baskin, Irwin) operated out of Bullfrog UT, Leg 2 operated (Andrews, Foster, Moore, Nichols) out of Page, AZ.
