Vehicle Dynamics Sensors for DASthe ground, others arise from geological complexities or are subjective in nature, etc. These errors are discussed and methods of their estimation and, where appropriate, of their treatment are given. The main applications of the CDP-derived velocities are briefly reviewed.

Seismic Profiling for Coal on Land,pecial consideration must therefore be devoted to calculation of static corrections and removal of ground roll..The limits to the resolution of minor faulting are controlled by the magnitude of the static errors rather than by the bandwidth of the data.

Seismic Sources on Land,te when it is driven with a sinusoidalforce is shown to be equivalent to voltage and current components in a simple network. A similar analogue illustrates the action of a weight drop source which is then compared with the vibrator and other energy sources.
