Abstract
This disclosure is related generally to marine surveying. An apparatus for generation of seismic waves in a body of water may include a wave generator. The apparatus may further include a housing defining an internal chamber having an open end. The housing may include baffles positioned between the open end and the wave generator. The housing may further include a vent positioned on an opposite end of the housing from the baffles.
Claims20
An apparatus for generation of seismic waves in a body of water, comprising:
- a housing defining an internal chamber having an open end in a bottom portion of the housing, wherein the housing comprises:
- baffles positioned proximate the open end;
- and
- a vent positioned at a top of the housing;
- and
- a wave generator disposed within the internal chamber of the housing and in a position between the baffles and the vent.
3 more elements
A method for geophysical surveying, comprising:
- towing a seismic source in body of water, wherein the seismic source comprises a wave generator positioned within an internal chamber of a housing, wherein the internal chamber has an open end in a bottom portion of the housing;
- actuating the wave generator such that a seismic signal is emitted from the seismic source through one or more baffles in the housing, wherein the one or more baffles are positioned proximate the open end;
- closing the one or more baffles;
- and
- opening one or more vents positioned at a top of the housing such that one or more recompressed bubbles formed in the housing are released through the one or more vents.
2 more elements
An apparatus for generation of seismic waves in a body of water, comprising:
- a seismic source comprising:
- a housing comprising:
- an inner wall defining an internal chamber, the internal chamber having an open end in a bottom portion of the housing;
- an outer wall spaced apart from the inner wall to define a vacuum cavity therebetween;
- a vent positioned at a top of the housing;
- and
- baffles positioned in the internal chamber proximate the open end;
- and
- an air gun disposed within the internal chamber of the housing and in a position between the baffles and the vent;
- and
- a cradle assembly that holds the seismic source.
