Evaluation Of High Resolution Seismic For Characterization Of The Owens Lake, California, Aquifer System

High resolution seismic reflection data are being used as part of an integrated program to characterize the ground water system of the Owens Lake, California, area. The feasibility study for the project consisted of acquiring data in both river delta and alluvial fan depositional settings. We performed a series of noise tests to determine the best seismic sources, receivers and<br>other acquisition parameters. Noise test data were evaluated using a field-based processing system. We acquired approximately two miles of Z4-fold high lbesolution seismic reflection data for evaluation. We simulated reduced fold geometries during processing to determine the optimal fold coverage for A large scale survey. Reflection data were acquired to 1/2 second (twoway<br>traveltime), representirlg a useful depth of investigation of roughly 1500 feet.
