ABSTRACT:
A method for seismic prospecting in a body of water which comprises trailing a gun adapted to initiate explosively-operated charges at a sufficient depth below the water's surface to allow the creation in the body of water of high-pressure waves, and detecting the pressure waves with a detector assembly including a housing having a flexible, sound-transmitting wall defining a chamber, an incompressible liquid completely filling the chamber, and a detector probe completely immersed in the incompressible liquid.
