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.

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 far-field detection apparatus for measuring a far-field signature of a seismic source includes a main tow cable, a depth control device, sensor lines, at least two deflectors and seismic sensors. The depth control device is attached to the main tow cable. Each of the sensor lines has a first end attached to the main tow cable. Each of the deflectors is attached to a second end of the sensor lines, respectively. The deflectors are configured to generate forces pulling the sensor lines away from the main tow cable. The seismic sensors are attached between the first end and the second end of each of the sensor lines. The seismic sensors are configured to measure seismic waves generated by the seismic source.
