The possibility of using acoustic methods to monitor in situ the response of sea grasses to environmental factors is investigated. The effects of photosynthesis on sound propagation have been observed in prairies of Posidonia oceanica (L.) Delile. This paper reports some results of one of the experiments conducted in the marine reserve of the island of Ustica, off Sicily, in September 1999. The long-range propagation of an acoustic signal and the ambient noise were measured during four days… CONTINUE READING
