Data Type(s): Location-Elevation: Navigation, Seismics: Sub Bottom Profiler, Sonar: Multibeam, Sonar: Sound Velocity
Scientific Purpose/Goals: Collect multibeam bathymetry and sub-bottom data within Lake Powell and at the confluence of several rivers (Colorado, Escalante, San Juan)
Start Port/Location: Salt Lake City, Utah
End Port/Location: Salt Lake City, Utah
Start Date: 2017-10-03
End Date: 2017-11-17
Equipment Used: HYPACK, POS-MV, EdgeTech 424 chirp sub-bottom profiler, Reson T20-P, Sensor - SVP
Information to be Derived: Bathymetry, backscatter and sub-bottom data will be collected.
Summary of Activity and Data Gathered: 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.
