Measurement of In Situ Acoustic Properties for the ONR Geoclutter Program

Abstract

The long-term objective of the GEOCLUTTER program is to understand the causes and implications of geologic clutter (reverberation) in a geologically well-characterized shallow-water environment. The field area selected for the GEOCLUTTER program is the mid-outer continental shelf off New Jersey, USA. The New Jersey margin was chosen for the GEOCLUTTER study because the bathymetry and portions of the shallow subsurface of this area had already been mapped in detail as part of an earlier ONR program aimed at understanding the origin of subsurface stratigraphy on continental margins (STRATAFORM). In addition to multibeam bathymetry, calibrated backscatter data (at 95 kHz from the multibeam sonar) was also collected as part of the STRATAFORM program.
