Abstract : Measurements of acoustic volume scattering from bubbles made during the Scripps Pier Bubble Experiment (24 February - 14 March 1997) are discussed. The measurements were made with APL-UW's SALMON (Shallow water Acoustic Light-weight MONitor) system consisting of an array of four upward-looking transducers which operate at 240 kHz. Measurements from this system were coordinated with measurements made by NRL-SSC, IOS APL-UW, SIO, NCPA, and NRL-DC for the purpose of studying bubble populations in a near-shore environment. Data from this and future experiments will be interpreted vis a vis the coastal oceanography and used to model the effect of bubbly environments on sonar system performance.
