Abstract:

Measurements of acoustic transmission, reverberation level, reverberation coherence and bottom loss were made at a site off the West Coast of Florida in 200 feet of water. Standard Navy explosive sound signals were dropped by an aircraft and recorded aboard an anchored research vessel. The transmission results are found to have both some explainable and un-explainable features. The reverberation data have been interpreted in terms of a scattering strength consistent with deep water measurements, and a coherence angle describing the vertical distribution in angle of the reverberant return.
