The Effect of Seasonal Temperature Fluctuations in the Water Column on Sediment Compressional Wave Sle, temperature fluctuations of as much as twelve degrees Centigrade have been observed. These seasonal variations in water column temperature affect the pore water temperature of the bottom sediments which, in turn, affects the compressional wave speed profile. Using Biot theory, it is shown that t

The quasi-sinusoidal rays can be thought of as taking a partial Fourier transform of the sound speed field (Cornuelle and Howe, 1987). The SLICE89 experiment was conducted in the northeast Pacific during summer 1989 to determine h

Chaos in Underwater Acoustics range-independent problem the divergence between neighboring ray trajectories is slow (power law behavior). In the generic range-dependent problem some ray trajectories exhibit extreme sensitivity to initial conditions (chaotic behavior) wherein neighboring trajectories diverge exponentially. Using

The wavefront characteristic that allows determination of the source depth is shown to be the distance between the two distinct wavefronts that result from the upgoing and down-going rays at the source. The effect of internal waves
