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.

Abstract: A system and method for reconstructing a far field signature with data fusion from near field, mid field, and surface field hydrophone recordings is disclosed. The method includes receiving a first trace from a first sensor (e.g., hydrophone) and a second trace from a second sensor located in a different field from the first sensor. The method also includes receiving position information for the first and second sensors. The method further includes reconstructing a far field signature of the seismic signal based on the first trace, the second trace, and the position information.

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.
