Area of Science:

  • Ocean Acoustics
  • Wave Propagation Physics
  • Geophysical Fluid Dynamics

Background:

  • Broadband acoustic propagation measurements were collected during the 1994 Acoustic Engineering Test.
  • Understanding acoustic energy transport in the ocean is crucial for climate monitoring and underwater acoustics.

Purpose of the Study:

  • To interpret acoustic propagation measurements using a ray-based wave-field description.
  • To investigate the consistency of ray-based simulations with measured acoustic observables, considering chaotic ray trajectories.

Main Methods:

  • Employed a ray-based wave-field description for analyzing acoustic propagation data.
  • Conducted ray-based numerical simulations incorporating mesoscale and internal-wave sound-speed perturbations.
  • Analyzed acoustic observables including wavefront time spread, intensity PDF, and reception finale energy distribution.

Main Results:

  • Ray-based simulations accurately reproduced measured acoustic observables.
  • Consistency was achieved despite predominantly chaotic ray trajectories, highlighting the robustness of the ray-based approach.
  • The study explored the implications of ray chaos and the nonlocal nature of eigenrays.

Conclusions:

  • Ray-based models are effective for interpreting complex acoustic propagation in the ocean, even under chaotic conditions.
  • The findings challenge theories relying on simple perturbation expansions about background rays.
  • This work advances the understanding of acoustic wave phenomena in dynamic ocean environments.
