Claim:
1. A method of enriching an acquisition bandwidth of seismic data related to a subsurface of a body of water, the method comprising: towing underwater along a first line of sail (i) at a first depth, at least one seismic source configured to generate a seismic wave and (ii) at a second depth, at least one streamer having at least one receiver configured to record reflections in the subsurface of the seismic wave; firing the at least one seismic source while being towed along the first line of sail; recording the reflections of the seismic wave along the first line of sail; changing (A) the first line of sail to a second line of sail, and (B) the first depth to a third depth different from the first depth, or the second depth to a fourth depth different from the second depth; towing underwater, along the second line of sail, the at least one seismic source and the at least one streamer, the at least one seismic source being towed at the third depth, or the at least one streamer being towed at the fourth depth; and recording new reflections along the second line of sail.
