Variability in the ocean sound-speed field on time scales of a few hours and horizontal spatial scales of a few kilometers is often dominated by the random, anisotropic fluctuations caused by the internal-wave field. Results have been compiled from a

An intuitive picture of ocean sound channel propagation from point sources is developed in terms of impulse response. The entire wavefront is described for fixed times that are appropriate for propagation to ≈ 1000 km. The wavefront characteristic

A 131‐element, 2‐D billboard array with 12‐kHz bandwidth per element and interelement spacing equal to half‐wavelength at 3.75 kHz was designed and built by the Marine Physical Lab. It recorded data nearly continuously over 8 days in July, 20

Atmospheric infrasound data and co‐located, three‐component seismic data have been collected by the eight microbarometers of the International Monitoring System (IMS) station and the IRIS seismic station at Pinon Flat (PFO) plus five additional m

Wave fronts propagated over 1000 km in the North Pacific Ocean in July 1989 are analyzed for internal‐wave effects. Approximately 1 week of pulses emitted once an hour and 20 h of pulses every 10 min are available from the SLICE89 experiment; the p

Parabolic‐equation numerical simulations which utilize environmental data and which take into account sound‐speed perturbations obeying the Garrett–Munk spectral model for internal waves have been carried out. Several effects of these simulated

We have developed a generalization of the method of statistical linearization to enable us to describe transient and other nonstationary phenomena obeying stochastic nonlinear differential equations. This approximation technique provides an optimal G

The complete wave field over a small region around 1000 km from a pulsed source is reconstructed in two ways. First, all the rays from the source to a vertical array of receivers at 1000 km are found, along with their travel times, number of caustics

Using the SDSC/CRAY and the parabolic equation, pulse propagation was simulated in the ocean sound channel. Pulses with 200 frequencies between 10 and 50 Hz were synthesized, giving a pulse width of approximately 25 ms, and a pulse repetition time of
