The Ocean Acoustics library contains acoustic modeling software and data. It is supported by the U.S. Office of Naval Research (Ocean Acoustics Program) as a means of publishing software of general use to the international ocean acoustics community.
ONR's BASSEX program is studying the acoustic shadows cast by seamounts. The example above shows the bathymetry, along with measured TL for a recent test near the Kermit-Roosevelt seamount in the North Pacific. The strong shadowing effects are clearly visible. Three-dimensional acoustic models (lower panels) are being validated using a benchmark problem with a conical seamount. (This page highlights current research projects in ocean acoustics. Suggestions welcome.) Previous FrontPages.
