Patent abstract
An air gun for use in generating seismic energy impulses operable at pressures below 1000 psi that reduces high frequencies and cavitation around the discharge of the air gun in order to mitigate damage to the marine environment, the air gun providing a sliding seal at the firing piston, an extension of port widths beyond the diameter of the firing piston and capability to control the speed of the shuttle assembly to reduce and eliminate some of the possible causes of the objectionable high frequencies and cavitation.
