—— In 2011, I went to Panama, thanks to funding from the National Science Foundation, to measure the soundscape of a coral reef in the Pacific. I analyzed these data and compared the acoustic environment of Panama to the acoustic environment of the Florida Keys. The Panama soundscape had clear temporal patterns indicative of biological chorusing of certain animals, and was higher in overall amplitude than the Florida reef. The stark differences observed in these two reef habitats may be relevant for the adults living on these reefs, and for the larval organisms that are trying to find their way to these reefs. We suggest that acoustic measurements should become a standard practice with any biological monitoring.
