Distributed seismic source array for use in marine environments

A marine sound source configured for use in a marine environment, comprising:

• at least one rotary motor;
• two opposed transducer face plates attached to an external pressure housing via a plurality of flexible watertight seals;
• at least one mechanical connection between the two opposed transducer face plates which causes the two opposed transducer face plates to move in unison;
• a connection means between the at least one rotary motor and at least one of the two opposed face plates configured for translating rotary motion of the at least one rotary motor into linear motion of the two opposed transducer face plates;
• and
• a pressure deflecting plate configured so that a displaced water volume from the back plate is redirected orthogonal to movement of the back plate;
• wherein a first of the two opposed transducer face plates is a front plate that radiates pressure waves outwardly from its face in a primary sound pressure radiation direction and a second of the two opposed transducer face plates is a back plate.

• and
• a pressure deflecting plate configured so that a displaced water volume from the back plate is redirected in a direction to cancel out the force from the front plate;
• wherein a first of the two opposed transducer face plates is a front plate that radiates pressure waves outwardly from its face in a primary sound pressure radiation direction and a second of the two opposed transducer face plates is a back plate.

A marine sound source configured for use in a marine environment, comprising:

• a housing;
• a moveable plate;
• a rotary motor;
• a connection means configured to translate rotary motion of the rotary motor into linear motion of the moveable plate within the housing;
• and
• a plurality of pressure release ports in a periphery of the housing located orthogonal to a linear motion of the moveable plate;
• wherein the plurality of pressure release ports are configured to allow liquid from the marine environment to freely flow inside and outside the housing.
