Abstract
A method and source element for generating seismic waves in water. The source element includes a housing having an opening; an acoustic piston closing the opening; an actuating mechanism located inside the housing and configured to actuate the acoustic piston; and a decoupling mechanism interposed between the acoustic piston and the actuating mechanism. The decoupling mechanism allows the acoustic piston to move substantially independent of the actuating mechanism for a first frequency range.
