seismic record (seismogram) The output of a seismic recording system (seismograph), e.g. a paper or film record, showing the seismic wiggle traces, usually for a single shot spread. In refraction surveys, many shots into one spread may be summed by a signal-enhancement seismograph to produce a single record. When records are processed they can be placed side by side along a profile to form a ‘seismic section’.
