Comprehensive Approaches to Advanced Three-Dimensional Ocean Acoustics Studies

Abstract

Underwater sound propagation, scattering and ambient noise in the ocean can be affected by many environmental factors. To assert the performance of underwater acoustic technologies, the effects of ocean environmental variabilities need to be considered when analyzing the acoustic signals. Thus, Ocean Acoustics (OA) is interconnected with many other fields of marine science, including physicaloceanography (PO), marine geology (GEO), marine biology (BIO), meteorology (MET), as well as signal processing, electrical and mechanical engineering that provide the technology backbone enabling real world ocean acoustics applications. The primary research objective of this proposal is to investigate three-dimensional (3D) acoustic propagation and scattering in complex marine environments, along with the following project tasks:A. Developing advanced 3D acoustics testbed models,B. Conducting a 3D acoustic experiment,C. Ocean soundscape analysis and modeling, andD. Ultimately developing a framework for acoustic data assimilation modeling.Future research workforce development is also one of the project objectives, and training of students is planned.This abstract is publicly releasable.
