Arctic Toothed Whale Click Spectra and Spectrograms from Kong Oscar and Fisher Islands

Acoustic events for beluga and narwhal echolocation clicks from SoundTrap recordings at the Kong Oscar and Fisher Islands mooring sites. Each one-hour event includes a concatenated click spectrogram and a mean power spectrum for all detections. Summary statistics for each event show the number of detections and the one-third octave level ratio in decibels between selected bands.

Use Cases

• Classifying beluga versus narwhal echolocation clicks based on spectral differences mentioned in the description
• Analyzing mean power spectra and one-third octave level ratios for acoustic event characterization
• Training machine learning models for whale species identification using spectrogram images
• Studying Arctic marine mammal acoustic behavior from long-term mooring recordings

Strengths

• Data is derived from one-hour acoustic events at two distinct mooring sites (Kong Oscar and Fisher Islands)
• Each event includes two visual figures: a concatenated click spectrogram and a mean power spectrum
• Summary statistics include the number of detections and a one-third octave level ratio in decibels

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Last update date is unknown; freshness unverified
