In an acoustic‐oceanographic experiment (AFAR) performed near the Azores in 1975, frequencies from 400–4670 Hz were transmitted over a 35‐km wholly refracted path. In addition, a separate data set was gathered over a 3‐km path in 1973. Measurements of the intensity coherence function of time and frequency, intensity moments, and the probability distribution of intensity are presented and compared with predictions of fluctuations due to internal waves.
