Abstract
Method and marine acoustic source array for generating an acoustic wave in a body of water. The marine acoustic source array includes at least one sub-array. The at least one sub-array includes a float from which plural source points are attached. The source points may be provided on a curved line, straight line, or other desired shape so that a variable-depth source is obtained with a single float. The source points may be divided into groups and the groups may be provided on the curved line, straight line or other desired shape.
Claims20
A marine acoustic source array for generating an acoustic wave in a body of water, the marine acoustic source array comprising:
- a first sub-array configured to be towed by a vessel, the first sub-array including a first float and plural first source points connected to the first float,
- wherein the plural first source points are divided into at least three groups (G1 to G3) and each group is provided at corresponding first depths (D1 to D3) and each group includes at least one source point.
A marine acoustic source array for generating an acoustic wave in a body of water, the marine acoustic source array comprising:
- a first sub-array configured to be towed by a vessel, the first sub-array including a first float and plural first source points connected to the first float,
- wherein the plural first source points are provided at corresponding first depths (z1 to z4), each first depth being different from other first depths.
A method for generating an acoustic wave underwater, the method comprising:
- towing a marine acoustic source array underwater, wherein the marine acoustic source array includes a first sub-array;
- connecting plural first source points of the first sub-array to a first float;
- and
- generating the acoustic wave with the plural first source points, wherein the plural first source points are divided into at least three groups (G1 to G3) and each group is provided at corresponding first depths (D1 to D3).
A method for generating an acoustic wave underwater, the method comprising:
- towing underwater a marine acoustic source array that includes a first sub-array;
- connecting plural first source points to a first float of the first sub-array;
- and
- generating the acoustic wave with the plural first source points, wherein the plural first source points are provided at corresponding first depths (z1 to z4), each first depth being different from other first depths.
