Abstract: Apparatus and method for suppressing the initial and subsequent contractions of an air bubble used to generate a seismic signal, wherein the preferred embodiment a source of suppressor air is located immediately adjacent to the air valve source which creates the bubble, whereby the source of suppressor air is located within the expanded bubble when it approaches its largest diameter to allow the sudden and rapid release of suppressor air into the bubble to retard the contraction of the bubble. In a second embodiment, the air valve source itself defines the source of suppressor air.
