Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): David Twichell
Affiliate Investigator(s): Guy Gelfenbaum (Coastal and Marine program, Western Region); Mike Parsley (BRD, Cook, WA)
Information Specialist(s): David Twichell
Data Type(s): Imagery: Photo, Imagery: Video, Location-Elevation: Navigation, Sampling: Geology, Seismics: Sub Bottom Profiler, Sonar: Single Beam
Scientific Purpose/Goals: High-resolution seismic reflection, sidescan mapping, and sediment sampling of reservoir floor to determine the amount, distribution and types of sediment being trapped. These data are important to understanding changes in salmon spawning grounds and to quantifying changes in sediment supply to the coast.

Equipment Used: SIS1000 Sidescan sonar, Echosounder, Video camera - deep sea, Plugger GPS, Grab sampler, 35 mm camera, Knudsen CHIRP Sub-bottom Profiler
Information to be Derived:
Summary of Activity and Data Gathered: The work was done in cooperation with researchers in the Biological Resources Division in Cook, WA. Sidescan sonar imagery and chirp seismic profiles were collected during the first 8 days and video and sediment sampling was collected during the last 3 days. Most of the lake floor was imaged with the SIS-1000 which was set to scan 750-m to each side. Sub-bottom profiles were collected simultaneously with the sidescan imagery, and also along tie lines in one 10-km stretch of the reservoir. Windy conditions, and the fact that the post-impoundment sediment was usually too thin to resolve seismically, did not warrant extending the length of the cruise to collect more seismic data. Video images were collected at 48 stations in the reservoir, and sediment samples were recovered at 41 stations. Sidescan sonar: 287.7 km; Sub-bottom: 287.7 km; Video transects: 48; Sediment samples: 41; Bottom photos: 130.
