Spectrograms of characteristic bowhead and beluga whale signals.

a) Five bowhead whale calls recorded on 11 July 2017 (FFT 2048, 50% overlap, Hann window). b) Beluga whale calls recorded on 4 May 2017 (FFT 1024, 50% overlap, Hann window). Note the different frequency axes for the two species’ signals.
