Description
Summary:This supplementary file accompanies a journal 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 sound pressure level (SPL) difference in decibels (dB) between selected third-octave frequency bands. Visual inspection of the enclosed figures demonstrates clear differences between beluga and narwhal click spectra.
