ASA Silver Medal
The ASA Silver Medal is an award presented by the Acoustical Society of America to individuals, without age limitation, for contributions to the advancement of science, engineering, or human welfare through the application of acoustic principles or through research accomplishments in acoustics. The medal is awarded in a number of categories depending on the technical committee responsible for making the nomination. Recipients of the medal are listed below. Silver Medal Source: Acoustical Society of America Silver Medal in Acoustical Oceanography 1993 – Clarence S. Clay – for contributions to understanding acoustic propagation in layered waveguides, scattering from the ocean's boundaries and marine life, and ocean parameters and processes. 1997 – Herman Medwin – for contributions to the understanding of acoustical scattering, absorption and ambient noise, particularly in relation to the acoustics of bubbles in the sea. 2004 – D. Vance Holliday – for contributions to the study of marine life, from plankton to whales. 2009 – Robert C. Spindel – for implementation of ocean acoustic tomography and basin scale acoustic thermometry. 2017 – Michael J. Buckingham – for contributions to the understanding of ocean ambient noise and marine sediment acoustics. Silver Medal in Animal Bioacoustics 1998 – Whitlow W.L. Au
