This supplementary file accompanies a research article focused on beluga and narwhal echolocation click classification. This document provides an overview of the data included in all beluga and narwhal acoustic events (each 1 hour) from SoundTrap recordings collected at the Kong Oscar and Fisher Islands mooring sites. There are two figures for each event: (1) concatenated click spectrogram, and (2) mean power spectrum for all detections within the event. Summary statistics are provided for each event showing the number of detections and the one-third octave level (TOL) ratio in decibels (dB) between selected TOL bands. Visual inspection of the enclosed figures demonstrates clear differences between beluga and narwhal click spectra.
