Current oil cleanup techniques are conducted at the ocean surface and disregard sinking oil and oil aggregates. Presently, there are no data involving ultrasonic tracking of oil within the water column. Research was conducted to find the required data by using acoustic measurements. A system was developed that allows the measurements of the specific acoustic impedance of oil as a function of its temperature and the acoustic frequency. The testing apparatus consisted of a fabricated chamber, testing tank, ice bath and pumping unit. The acoustic data obtained were at a satisfactory level, providing the necessary basis for further study and research.
