Long-Term Acoustic Recordings from Australian Eucalyptus Woodland

A set of long-term environmental audio recordings from the TERN Whroo Dry Eucalypt SuperSite in Australia, established in 2011. Recordings were scheduled for 12 hours per day, split between dawn and dusk periods, and include sensor data such as temperature and sound pressure levels. The site is a box woodland dominated by Eucalyptus microcarpa and Eucalyptus leucoxylon at an elevation of 165 meters.

Use Cases

• Identify sound sources of interest, such as bird choruses, within the 12-hour daily recording schedule to assess fauna biodiversity.
• Characterize the soundscape and monitor temporal trends using long-term spectrograms generated for each audio file.
• Track environmental changes by correlating recorded temperature data with acoustic activity patterns across seasons.
• Analyze minimum, maximum, and mean sound pressure levels to study acoustic energy variations in the woodland ecosystem.

Strengths

• Long-term recordings initiated in 2012, providing over a decade of potential acoustic data for time-series analysis.
• Recordings capture 12 hours per day specifically timed for dawn and dusk bird choruses, targeting key biological activity periods.
• Sensor data includes temperature and multiple sound pressure level metrics (minimum, maximum, mean) alongside audio.
• Site metadata is detailed, including elevation (165 m), mean annual precipitation (558 mm), and seasonal temperature ranges.

Limitations

• The dataset size, number of audio files, and total recording duration are unspecified, making it difficult to assess scale.
• Data accessibility may be complex, requiring following specific bulk download instructions from an external wiki page.
• File formats listed (HTML, PNG, PDF) suggest primary data may be packaged with documentation rather than raw audio files.
