Abstract
A resonant source element is configured to generate seismic waves in water. The resonant source element includes a housing having two openings covered by first and second pistons, wherein the first and second pistons are configured to freely translate relative to the housing to generate the seismic waves; and a high-pressure system configured to discharge inside the housing and to actuate the first and second pistons. The first and second pistons are configured to oscillate after the high-pressure system is fired to generate low-frequency seismic waves.
