Fig 1. Screen interface of Matlab script tag3audit showing 20 s of concurrent data logged by the DTAG: depth (upper panel), spectrogram of sound (mid-panel), and tri-axial acceleration (lower panel) during chase and capture of prey by DLBB16-04.

Fig 1

Buzzing starts at 7 s, just 1 s before the onset of an acceleration jerk at 9 s (presented as a breakdown of the 3 axes, pitch–X axis, roll–Y axis, and heading–Z axis, to highlight the Y axis contribution), while the whale was just below the surface. Time zero equates to 30.2 hrs since the whale was released, or 1:38 am AKDT on 16 May 2016.
