Abstract:

A need exists in both the civilian and military communities for an automated seafloor classification system that can remotely and accurately estimate and map sediment properties for a number of seafloor engineering applications and for input to acoustic propagation prediction models. Over the past several years the Naval Research Laboratory NRL has been developing a normal incidence, narrow beamwidth, high resolution seismic system that has the capability to accurately predict, in near real-time, acoustic impedance, sediment type and a number of selected geotechnical properties of the upper several meters of the seafloor while in an underway survey mode, Lambert. The system is designated the Acoustic Seafloor Classification System ASCS and is technology based on the Echo-strength Measuring System EMS developed in the early 1980s by Honeywell ELAC of Kiel, Germany. A detailed description of this system can be found in Lambert and Fielder
