ABSTRACT:
A compressed-gas seismic energy source suitable for underwater prospecting. The device has two gas storage cylinders placed at the opposite ends of a shuttle. The shuttle seals both storage cylinders when seated at the end of its stroke and releases gas for the desired sonic pulse from both cylinders during its stroke. Design of the device provides for simplicity of operation, ready modification of the sonic signature, and reliability of moving parts.
