This tutorial reviews the basics of total seismic field de- sign and provides personal-computer-based computer language codes that can readily be used, with some mod- ification, to design seismic surveys in the field. The finite effective dynamic range of seismic recording systems to- gether with an overlap of signal and noise spectra suggest that a certain amount of prefiltering is needed during the acquisition phase to insure that a weak signal does not fall below the system noise, which would render the signal useless. The key elements of a total seismic field design are reviewed and, by way of a hypothetical 3-D field example, their implementation is illustrated.
