Recovery of low frequency data from 10Hz geophones

Malcolm B. Bertram and Gary F. Margrave


An analysis is made of the data from three different projects that provide the means to calibrate a method to recover low frequency data from 10Hz geophones. These surveys were selected because of the ability to directly compare the enhanced spectrum from the 10Hz geophones to that from 2Hz geophones, MEMs sensors, and/or seismometers, thereby providing a measure of the effectiveness of the method. The ability to recover usable data to two octaves below resonance is demonstrated.
