Abstract:

The long-term goal of the Marine Physical Laboratorys Adaptive Beach Monitoring ABM program is to determine the capabilities of small on-shore and off-shore seismoacoustic arrays along with directional wave and current sensors to provide the amphibious force commander with a covert monitoring capability of shore-based as well as near-shore enemy forces, near-shore current and wave dynamics, and beach surf conditions. Objectives The science objectives of the ABM program are to understand the source mechanisms of naturally occurring e.g., breaking surf and biological and manmade e.g., land vehicle seismoacoustic sounds in the near-shore region, the coupling of the seismic and acoustic fields in the earth and atmosphere into the ocean acoustic field, and the propagation characteristics of these sounds within the water column. The engineering objectives are to design signal processing structures, along with arrays of appropriate sensor types, to detect, track, and classify sounds of interest e.g., breaking surf and land vehicle sounds in the near-surf-zone environment.
