Figure 5: Data from a free-floating Dtag ensonified by a buzzing sperm whale that eventually bumps into the tag.

From: Sperm whale predator-prey interactions involve chasing and buzzing, but no acoustic stunning

Figure 5

(A) Absolute sound pressure level recorded by the tag. (B) The tag is ensonified at normal buzz rate clicking, and the clicks show the distinct monopulse nature of sperm whale on-axis clicks21, but the RLs never exceed 187 dB re 1 μPa (pp). (C) The waveform and (D) power spectral density (SPD) of the 5 most powerful clicks received on the tag (grey lines) and the mean overlaid (black line).
