LOW-FREQUENCY STANDARD HYDROPHONE * FOR CALIBRATING LINE HYDROPHONE ARRAYS (SEISMIC STREAMERS) AND MARINE SEISMIC SOURCES **

Geophysical Prospecting (1981)

Michal Šafář Patrick Newman

A bstract The design of a standard hydrophone with a maximally flat (Butterworth) response in the frequency range 8.0 Hz‐1.0 kHz is described. The standard hydrophone has been developed primarily for calibrating line hydrophone arrays (seismic streamers) and marine seismic sources. The standard hydrophone has been used successfully during the past eight years for monitoring the output of a single air gun. It can be used for the calibration of a marine seismic streamer.

ON THE MINIMIZATION OF THE DISTORTION CAUSED BY THE GEOPHONE‐GROUND COUPLING *

Geophysical Prospecting (1978)

Michal Šafář

A bstract It is well known that the application of the “bright spot’ technique has been more successful in marine prospecting than in land prospecting. This is due partly to the problem of distortion of the seismic signal caused by the geophone‐ground coupling, especially when carrying out high resolution, shallow seismic surveys in swampy terrain. The effect of geophone‐ground coupling on the response of a single geophone to the incident compressional waves has been treated by several authors. However, they have always neglected the influence of mutual interaction between an array of geophones on the response of each geophone forming the array. We show that mutual interaction, which results from the re‐radiation of the incident compressional waves by the geophones forming the array, can have considerable effect on the response of each geophone. The effect of the geophone‐ground coupling on the response of a seismic channel is considered in the absence and presence of mutual interaction between a group of geophones for the case when the shear wave velocity of the soil varies by a factor of three.
