- section：SEISMIC DATA ACQUISITION
Ground-coupling devices measure local conditions around a geophone and are therefore useful for geophone design. For purposes of gathering seismic data, the data from local ground-coupling experiments must be related to seismic data. In particular, the geophysicist wants to know whether a local measurement could help in detecting a ground-coupling problem or in correcting the seismic data for it. Two sets of field experiments have been carried out to investigate these effects. Our experimental data of coupling-measurement devices show that the behavior of well-planted spiked geophones is determined by shear along the spike, while the behavior of poorly planted geophones is determined by its weight. However, when a link is established between the data from a coupling-measurement device to seismic data, it becomes clear that the usefulness of this device for predicting problematic ground-coupling phenomena in seismic data is very limited.
