Abstract
A completely new electro-mechanical marine vibroseis concept is introduced that uses a flextensional shell with a uniquely developed form. Two controllable output resonances achieve a very high efficiency and repeatability, with a typical frequency bandwidth of 6 - 100 Hz. The marine vibrator can be used as a standard towed acoustic source in shallow water or as a stationary source in transition zone environments. Of particular significance, the vibrator requires only an electrical power supply, cannot leak hydraulic fluids, is easily transported, and is suitable for applications requiring very low environmental impact.
