Abstract
Pulsed cw signals were transmitted from an electromagnetic transducer situated in the deep sound channel, and were received by a hydrophone at a similar depth, at ranges of from 1 to 6 kyd. A study of the fluctuations of ∫ P2dt has shown that for the sound channel arrival, the relative fluctuations increase with range. For ranges from 2 to 6 kyd, the relative fluctuation is approximately KR1.1. The surface reflected arrival has a maximum relative fluctuation at 1 kyd, a minimum relative fluctuation at 3.4 kyd, and increasing scatter out to the maximum range. Tentative explanations for these phenomena, justification for the relating of results using ∫ P2dt to those using Bmax, plus correlation with results published by other scientists will be discussed.
