Field Activity 2000-027-FA

Identifier 2000-027-FA
Alternate names IB C-27-00-GC
Purpose 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.
Location Lake Mead, Arizona, Nevada, United States, North America,
Comments 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. Project = Lake Mead Geophysical Survey, Lake Mead Geophysical Survey Information from Foghorn: Knudsen chirp sub-bottom profiler with digital data logger for chirp system, EdgeTech 100-kHz sidescan system, ISIS sidescan logging, P-CODE GPS with HYPACK navigation package, Data processing computer, CD-ROM mastering system for data archival;
