Other ID: IB C-27-00-GC
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): David Twichell
Affiliate Investigator(s): Mark Rudin, UNLV
Information Specialist(s): David Twichell
Data Type(s): Imagery: Photo, Imagery: Video, Location-Elevation: Navigation, Sampling: Geology, Seismics: Sub Bottom Profiler, Sonar: Sidescan, Sonar: Single Beam
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 Port/Location: Las Vegas Bay Marina
End Port/Location: Las Vegas Bay Marina
Start Date: 2000-05-30
End Date: 2000-06-09
Equipment Used: GPS (wh), ARGO, Edgetech DF-1000 sidescan sonar, Echosounder, Knudsen CHIRP Sub-bottom Profiler

Summary of Activity and Data Gathered:
Staff: Kenneth E. Parolski, VeeAnn Atnipp Cross
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.
