Equipment Used
Develop calibration methods for high-frequency
acoustic sources. Collect calibrated profiles over Oakland Bay Bridge
East span boreholes. Collect 36-channel multi-offset data w/ high-
frequency sources. Measure near-field source strength and
attenuation as a function of  range and azimuth. Field test data
acquisition systems to be used on upcoming Gulf of Mexico
