摘要：

A shallow-water high-frequency (HF) acoustic propagation experiment was conducted just off shore in Panama City, FL, Several broad-band high-resolution sources and receivers were mounted on stable platforms and deployed in water depths of 8-10 m, Signals covering the frequency range from 20 to 200 kHz were transmitted from the sources to two spatially separated receivers, The data were analyzed to provide estimates of the signal phase variances as a function of frequency and source-to-receiver range, These phase variabilities are correlated with small-scale water column thermal variabilities and ocean swell conditions.
