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.
