Reciprocal transmission tomography experiments in the Florida Straits have yielded a month-long time history of reciprocal pulse responses over three ranges approximately 22 km in length and 250 m in depth. A transmitted pulse of 8.75 ms in duration

Measurements of acoustic transmission in a bottom‐limited sound channel with a surface duct, are compared with model predictions using broadband ray, normal mode, fast‐field, and parabolic approximation methods. At a range of 42 km, six surface

This research will focus on understanding the variability of acoustic propagation in shallow water areas by examining the fluctuations of acoustic mode energies in response to oceanographic changes not related to internal waves. The long-term goal of

Two physics‐based clutter models were developed for comparison and to study the merits and limitations of both approaches. The stochastic approach [Newhall and Arvelo, J. Acoust. Soc. Am. 118, 2041 (2005)] makes use of perturbation theory, to relat

Empirical fish species composition and distribution data obtained during a GeoClutter survey were input into scattering models for marine mammals [Love, J. Acoust. Soc. Am. 49, 816–823 (1971)] and for schools of fish [Feuillade et al., J. Acoust. S

Data from the acoustic surface reverberation experiment (ASREX) [Williams et al., J. Acoust. Soc. Am. 97, 3404 (1995)], is analyzed using multivariate Fourier and wavelet techniques to investigate relationships between environmental conditions and ob

A semi‐deterministic normal‐mode reverberation model has been developed that accounts for bistatic bottom micro‐slopes generated via bathymetric fractal realizations to simulate clutter scattering from seafloor interface features. This clutter

Strong correlation between acoustic ambient noise and backscattering strength was observed during analysis of data from the acoustic surface reverberation experment (ASREX) [Williams et al., J. Acoust. Soc. Am. 97, 3404 (1995)]. Traditional empirical

Preliminary results from a surface reverberation experiment performed in the North Atlantic during the winter of 1993–94 indicate that ambient noise levels may prove to be a convenient and accurate indicator of surface backscattering strengths. Bac
