Information to be Derived:

Summary of Activity and Data Gathered: Successful cruise! Bear Lake: Completed mosaic mapping with sidescan sonar and swath bathymetry; supplemented existing seismic data with additional Chirp profiles. Collected bottom samples at 20 stations (stored in Woods Hole with S. Colman). Foy Lake: Completed Chirp seismic survey of entire lake. Acoustic data and samples in Woods Hole with Ch. Sci. Preliminary data given to UT F&WS, UT State Parks and U. Oregon.
