Visualization and quantification of coral reef soundscapes using CoralSoundExplorer software
Fig 10
Three-dimensional visualization of the acoustic space of coral reef soundscapes using CoralSoundExplorer software.
Each dot corresponds to 15 seconds of sound recording. Recordings were made at three sites on the Bora-Bora reef (undisturbed site, tourist site and boat site), over 24-hour periods, defining a day period and a night period, repeated over 3 non-consecutive 24-hour days (replicates 1, 2 and 3). In panels (A), (B) and (C), each sound is colored according to one of these predefined labels. Panel (D) combines the three labels using the following nomenclature site/replica/period (site: undisturbed as Und., tourist as Tour., and boat as Boat, replicate number 1, 2, or 3, day and night as D or N) to form 18 predefined clusters (3*2*3 = 18). These graphical representations make it easy to explore soundscapes and qualitatively grasp their correspondence with predefined labels. CoralSoundExplorer’s interface is interactive, allowing the 2D or 3D representation to be oriented as desired and zoomed in on areas of interest. Each dot is associated with the corresponding sound recording, which can be listened to and exported with a click.
