Acoustic characteristics of bubble detachment (IMAGE)
Caption
(A to C) Acoustic signals of bubble detachment recorded in the coral reefs; (D to F) acoustic-video synchronous records of bubble detachment in the laboratory coral conservation tank. Specifically, (A) and (D) present representative transient acoustic waveforms; (B) and (E) illustrate the time frequency characteristics of the waveforms via spectrograms; and (C) and (F) show the power spectral density (PSD) of the respective acoustic signals. (G) A 2-second acoustic recording from the coral conservation tank, highlighting an acoustic signal of bubble release in a pink box. (H) The precise moment of bubble release, synchronously recorded with the acoustic signal shown in (G).
