Information Specialist(s): David Twichell
Data Type(s): Seismics: Sub Bottom Profiler, Sonar: Sidescan, Imagery: Photo, Imagery: Video, Sampling: Geology
Scientific Purpose/Goals: Seismic and sidescan mapping of deltas along the edge of the Las Vegas Bay part of Lake Mead to serve as a base map for coring and other environmental monitoring studies.
Start Date: 2000-05-30
Start Port/Location: Las Vegas Bay Marina
End Date: 2000-06-09

Summary of Activity and Data Gathered:
Staff: VeeAnn Atnipp Cross, Kenneth E. Parolski
Notes: A second component of the field work will include coring that will be completed during the week of July 11-18. This part of the work will require a P-code navigation system with a navigation laptop with MapInfo on it. The rest of the coring gear will come from elsewhere. Original Center People field contained: Ken Parolski - sidescan/seismic tech., VeeAnn Cross - data processor.
