Visualization and quantification of coral reef soundscapes using CoralSoundExplorer software
Fig 2
Soundscapes diversity in a coral reef.
(A) Spectrogram of a reef soundscape recorded during the day. Fish sounds (yellow square) are mostly concentrated at low frequencies (< 1 kHz). (B) Spectrogram of a reef soundscape recorded at night showing an overall increase of sounds levels mostly due to an increase in the number of snapping shrimp sounds. An unidentified fish sound is also present (yellow square). (C) Spectrogram showing the broadband noise of a passing boat, with higher intensity during the first 5 seconds. (D) Spectrogram showing broadband masking effect caused by rain. Spectrograms were plotted with CoralSoundExplorer, using FFT window size = 2048 samples, sampling frequency = 44100 Hz.
