Passive acoustic measurements of snapping shrimp from a reef monitoring feasibility test in Aruba
conference paper
In December 2013, TNO made underwater measurements in Aruba to assess the feasibility of reef health monitoring using passive acoustics; this work was conducted in collaboration with Aruba Ports Authority, Aruba Marine Park, and Aruba Reef Care Foundation. Ambient noise recordings were made at various locations around the reef over a period of several days and marine biologists performed a survey to assess the species present and to identify healthy and unhealthy regions of reef. This paper presents results from the ambient noise analysis. The underwater soundscape was found to be dominated by snapping shrimp noise. The sounds from other species known to be present were not observed, presumably due to their low levels and due to measurements made at a distance from the reef. We present an analysis of the shrimp noise, for which we observed a diurnal trend, and conclude with some comments on the feasibility of reef health monitoring.
