Bottom interacting sound at 50 km range in a deep ocean environment.

Data collected during the 2004 Long-range Ocean Acoustic Propagation Experiment provide absolute intensities and travel times of acoustic pulses at ranges varying from 50 to 3200 km. In this paper a subset of these data is analyzed, focusing on the effects of seafloor reflections at the shortest transmission range of approximately 50 km. At this range bottom-reflected (BR) and surface-reflected...

Observationally constrained modeling of sound in curved ocean internal waves: examination of deep ducting and surface ducting at short range.

A study of 400 Hz sound focusing and ducting effects in a packet of curved nonlinear internal waves in shallow water is presented. Sound propagation roughly along the crests of the waves is simulated with a three-dimensional parabolic equation computational code, and the results are compared to measured propagation along fixed 3 and 6 km source/receiver paths. The measurements were made on the ...

Simulation of Bottom-interacting Ocean Acoustics: Transition into New Applications

The ability to accurately and efficiently model the sound field in the water column when there exists significant acoustic interaction with the seafloor is critical in a variety of ocean-acoustic applications. Simulation methods with detailed fundamental treatments of the effect of acoustic energy on an elastic solid are often insufficiently robust when the environment is complicated or when lo...

Acoustic identification of a single transmission at 3115 km from a bottom-mounted source at Kauai

Sounds received in the Gulf of Alaska at 3115 km from the ATOC/NPAL source at Kauai (75 Hz, 0.027-s resolution, bottom-mounted) are compared with acoustic and oceanographic models. Unlike data collected at stationary SOSUS arrays, these data come from a towed horizontal array at 372-m depth of military origin. A plausible identification of the acoustic reception is made despite the fact that on...

Deep seafloor arrivals in long range ocean acoustic propagation.

Ocean bottom seismometer observations at 5000 m depth during the long-range ocean acoustic propagation experiment in the North Pacific in 2004 show robust, coherent, late arrivals that are not readily explained by ocean acoustic propagation models. These "deep seafloor" arrivals are the largest amplitude arrivals on the vertical particle velocity channel for ranges from 500 to 3200 km. The trav...
