Mike Buckingham’s team deployed the Fly-By array at two sites, one shallow (15 m) and one deep (100 m), during the Makai experiment (10/21/05 to 10/28/05). The array was deployed from a small boat chartered from a local dive shop. A Maule MXT7-180 STOL aircraft, chartered from Air Ventures Hawaii, was used to overfly the array. To make the upper … Read More

DeepSound is a high-bandwidth acoustic recording, free-falling system designed to profile ambient noise from the surface to depths of 12 km. The recording platform is autonomous and descends under gravity at 0.5 m/s to its pre-programmed maximum depth, where a burn wire releases a weight, permitting the system to return to the surface under its own buoyancy. Movies DeepSound III … Read More
These are some sample recordings made on two different airplanes: the Cessna 172SP and the Diamond Star. All recordings are closest point of approach. A gain was applied when converting the data into a wave file to bring the recordings into audible range. The gain was 500 for Hydrophone 1 (H1) and the microphone. The gain was 4000 for … Read More
This study investigates the acoustic emissions of a water jet impinging on a flat surface of water and applies the acoustics to the study of the hydrodynamics and entrainment characteristics of the jet. As the jet penetrates the surface, air is entrained in the form of bubbles which produce sound by various mechanisms including amplification of turbulent noise, collective bubble … Read More
