Dynamically-Adjusted Variable-Depth Seismic Source and Method

摘要

Method and dynamically-adjusted marine acoustic source array for generating an acoustic wave in a body of water. The acoustic source array (1000) includes a float (1002); plural actuation devices (1030a to 1030e), each actuation device having corresponding cables (1006); and plural source points (1008a to 1008e) connected to the float (1002) through the corresponding cables (1006). The plural actuation devices (1 030a to 1030e) dynamically adjust corresponding lengths of the corresponding cables (1006) to achieve a desired variable-depth profile for the plural source points (1008a to 1008e).
