A stereo spectrogram of Antarctic blue whale vocalisations, recorded in the southwestern Indian Ocean. Each in the series of calls starts at a frequency of approximately 27 Hz, before gradually swooping downward to about 18 Hz.
This stereo track is a rendering of the 3 components of the motion of the seafloor at a 4.264 km depth. The seismograms were recorded on 31 May 2013, from 12.30 to 13.00 GMT, by the ocean-bottom seismic station RR43 of the RHUM-RUM network (27.53S, 65.58E) (Dréo, R. 2018).
