Shipping Low Frequency Noise and Its Propagation in Shallow Water

Low Frequency Acoustic Intensity Propagation Modeling in Shallow Water Waveguides

12: Shallow Water Propagation

Shallow-Water Propagation

(A) For elastic sediments we derived a new PE formulation [1] that unlike any predecessor handles layered environments accurately and efficiently while remaining numerically stable. This formulation, based on different computational variables, can treat range dependent sediments and properly account for energy conservation [2]. We demonstrated additional properties and advantages of the new met...

Shallow Water Propagation and Surface Reverberation Modeling

The primary long-term goal is to measure and model high-frequency acoustic propagation in the presence of surface gravity waves and breaking waves to better understand the effects of surface reverberation on shallow water, underwater acoustic communications (ACOMS). Secondary long-term goals are to exploit measurements of breaking wave noise to infer bubble cloud populations at the sea surface ...
