Résumé

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 Atlantic water from cold Arctic water had horizontal sound speed changes of 30 m/s over a range of 50 km. The acoustic effects of the front for a 150 km transmission path were found to be significant (> 10 dB), but with strong dependence on environmental parameters as well as on source/receiver depths and frequency.
