Alice Mulga Acoustic Data Collection from 2013 to 2019

Australia's Alice Mulga SuperSite contains audio files recorded from 2013 to 2019 in low open woodland mulga, hummock grassland, and river red gum forest. The Terrestrial Ecosystem Research Network collected 12 hours of audio per day, split between dawn and dusk, along with temperature and sound pressure level data. Acoustic indices and false colour spectrograms were generated to aid in analyzing the soundscape.

Use Cases

• Characterize soundscapes and monitor environmental changes based on acoustic indices.
• Identify specific sound sources like birds or insects based on false colour spectrogram visualizations.
• Assess fauna biodiversity trends over time based on long-term acoustic recordings.
• Analyze correlations between acoustic activity and recorded temperature or sound pressure levels.

Strengths

• Data collection spans 7 years from 2013 to 2019.
• Includes derived data products like acoustic indices and false colour spectrograms.
• Recording schedule of 12 hours per day is explicitly designed to capture key biological events.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
