SOUND PROPAGATION THROUGH AN OCEANIC FRONT
The effect of ocean fronts on long-range sound propagation in the ocean has been investigated theoretically. A numerical model of the parabolic equation (PE) type was used for simulating propagation across a real front observed on the Faroe-Iceland Ridge in October 1985. The front separating warm At...
