ABSTRACT:
An apparatus for sweeping contaminating material such as oil along the surface of a body of water using acoustic waves as a propelling force. The vibrational waves are produced by a device supported below the water surface and aimed upwardly towards a peripheral edge of the oil spill. Vibrational waves generated when the device is activated strike the air above the water surface and as a result are compacted into a flattened and horizontally elongated zone of vibrational energy which exerts a driving force on the oil spill edge. A method of employing sound as a sweeping force.
