Abstract:

A portable underwater source-receiver system, supporting equipment, and digital computer software have been developed to determine near-surface sound speed and attenuation at harmonic frequencies from 5 to 95 kHz simultaneously, and in-situ from a ship. These data have yielded values of bubble densities as a function of bubble radius from 40 to 1000 microns, depth to 15.2 meters, time of day, varying oceanographic conditions and environmental parameters for two days in November in Monterey Bay.
