Litchfield Savanna Acoustic Recordings with Temperature and Sound Pressure Data

Featuring acoustic recordings from two recorders in Litchfield National Park, Australia, collecting 12 hours of audio per day split between dawn and dusk periods. The sensors also recorded temperature, minimum, maximum, and mean sound pressure levels. The data collection began in 2015 and is part of the Terrestrial Ecosystem Research Network's long-term ecosystem monitoring.

Use Cases

• Analyze daily patterns in mean sound pressure levels to correlate with dawn and dusk bird choruses.
• Investigate the relationship between recorded temperature and sound pressure levels in a tropical savanna environment.
• Use long-term spectrograms (PNG files) for automated detection of specific avian or environmental acoustic events.
• Study seasonal variations in minimum and maximum sound pressure levels captured over multiple years.

Strengths

• Data collection spans multiple years, with recordings initiated in 2015.
• Sensors capture multi-modal data including audio, temperature, and sound pressure levels.
• Recording schedule is structured to capture ecologically significant periods (dawn and dusk choruses).
• Data is part of a long-term monitoring site established in 2013 within a representative northern Australian ecosystem.

Limitations

• The specific number of audio files, total data size, and recording date range are not provided.
• Data is delivered in HTML and PNG formats, which may require processing to extract raw audio or numerical sensor data for analysis.
• The geographic scope is limited to a single 1-hectare plot within Litchfield National Park.
