1. A method for locating an acoustic source comprising:
providing a first linear array at a first depth in a plane;
providing a second linear array at a second depth in the same plane as the first linear array;
receiving signals from the acoustic source at each of the first linear array and the second linear array;
resolving signals received at the first linear array into a first cone of possible acoustic source locations;
resolving signals received at the second linear array into a second cone of possible acoustic source locations; and
estimating a contour of possible acoustic source locations at an intersection of the first and second cones of possible acoustic source locations.
