Abstract
Method and dynamically-adjusted marine acoustic source array for generating an acoustic wave in a body of water. The acoustic source array includes a float; plural actuation devices, each actuation device having corresponding cables; and plural source points connected to the float through the corresponding cables. The plural actuation devices dynamically adjust corresponding lengths of the corresponding cables to achieve a desired variable-depth profile for the plural source points.

A dynamically-adjusted marine acoustic source array for generating an acoustic wave in a body of water, the dynamically-adjusted marine acoustic source array comprising:
- a first float;
- plural first actuation devices connected to the first float, each actuation device having corresponding first cables;
- and
- plural first source points connected to the first float through the corresponding first cables,
- wherein the plural first actuation devices dynamically adjust corresponding lengths of the corresponding first cables to achieve a first desired variable-depth profile for the plural first source points.
A dynamically-adjusted marine acoustic source array for generating an acoustic wave in a body of water, the dynamically-adjusted marine acoustic source array comprising:
- a first float;
- plural first source points;
- and
- plural first actuation devices connected to the plural first source points, each actuation device having corresponding first cables that are attached to the first float,
- wherein the plural first actuation devices dynamically adjust corresponding lengths of the corresponding first cables to achieve a first desired variable-depth profile for the plural first source points.
A method for generating an acoustic wave underwater with an adjustable depth marine acoustic source array, the method comprising:
- towing the 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 through plural first actuation devices and corresponding first cables;
- adjusting lengths of the corresponding first cables to achieve a desired first variable-depth profile of the plural first source points;
- and
- generating the acoustic wave with the plural first source points having the desired first variable-depth profile.
