Estimation of seafloor properties using low frequency acoustic signals
Abstract
The US capabilities for undersea warfare are dependent on our understanding how theoceanography, and the seabed, impacts system performance. This proposed project at theUniversity of Rhode Island addresses several priority areas for the US Navy. URI s proposedefforts are a continuation of past research focusing on the role of seabed characteristics on thelow frequency acoustic propagation in both shallow and deep water. We have maintained anactive research program, based heavily on field data collection through ONR-sponsoredexperiments, for more than 20 years. Some of our recent work has extended our capabilities intodeep water; specifically, into investigating the acoustic interaction (scattering, reflection,diffraction etc.) with seamounts and complex bathymetry. We also proposeto engage a diversegroup of students (both graduate and undergraduate) in different aspects of research activitiesincluding actively participating in ONR sponsored research cruises. We have had severalstudents participate in some of the recent ONR experiments such as the Seabed CharacterizationExperiment (SBCEX-2022) and the New England Seamount Acoustic (NESMA) experiment.
