Environmental correlate of acoustic impulse response and arrivals with solibore propagation in ASIAEX SCS experiment

Abstract

An ASIAEX South China Sea experiment was conducted in April–May 2001. The experiment site is characterized as an active internal tide/solibore propagation region along the northwestern shelf break of the South China Sea. On May 4–5, one package of solibore propagated through the sources and receiver arrays as clearly seen from the satellite image and the temperature time series recorded in the environmental moorings. The propagation path of the solibore is reconstructed using the data from the environmental moorings. In this paper we also present results of the acoustic impulse responses and the arrivals of the same time as the solibore passing through. Correlations of the acoustic impulse responses and the arrivals with the solibore propagation show the solibore’s effect on the acoustic propagation when the solibore enters the acoustic propagation paths.
