Correction to: Scientific Reports https://doi.org/10.1038/s41598-022-15379-0, published online 09 August 2022


The original version of this Article contained errors.


Firstly, to increase its readability, Figure 1 was swapped with a black and white version of the image.


Consequently, the legend of Figure 1


“Spectrogram of a fin whale pulse sequence recorded by the Bombyx buoy in October 2018. Spectrogram parameters are described in section "Spectro-temporal pulse analysis". Dots show the center frequencies of the detected pulses, with white dashed lines showing the IPIs. The grey dashed line denotes the discrimination threshold between A and B pulse types, at 20 Hz.”


now reads:


“Spectrogram of a fin whale pulse sequence recorded by the Bombyx buoy in October 2018. Spectrogram parameters are described in section "Spectro-temporal pulse analysis". Dashes show the center frequencies of the detected pulses, with grey dashed lines indicating the IPIs. The blue dashed line denotes the discrimination threshold between A and B pulse types, at 20 Hz.”


Secondly, in Figure 8 the histogram did not accurately display the densest bins for the months of the year. Furthermore, the Figure wrongly scaled the data from 0 to 70 instead of from 100 to 102.


The original Figure 1 and 8 and accompanying legends appear below.

Bi-histogram of the center frequencies against months of the year. The horizontal line shows the separation between type A and type B pulses. The fitted linear model is shown as a black dashed line.
