  • Title: Mid-frequency sound propagation through internal waves at short range with synoptic oceanographic observations.
    Author: Rouseff D, Tang D, Williams KL, Wang Z, Moum JN.
    Journal: J Acoust Soc Am; 2008 Sep; 124(3):EL73-7. PubMed ID: 19045565.
    Abstract:
    Preliminary results are presented from an analysis of mid-frequency acoustic transmission data collected at range 550 m during the Shallow Water 2006 Experiment. The acoustic data were collected on a vertical array immediately before, during, and after the passage of a nonlinear internal wave on 18 August, 2006. Using oceanographic data collected at a nearby location, a plane-wave model for the nonlinear internal wave's position as a function of time is developed. Experimental results show a new acoustic path is generated as the internal wave passes above the acoustic source.
