Under water, we can use echo-sounding sonar to plot the floor of the ocean, which can send back signals of the outline of particular shapes, ever so deeply concealed, or else sensitive listening devices can detect characteristic soundwaves, travelling in straight lines for miles through water, emanating from machines and engines.
