Karawatha Peri-Urban Acoustic and Environmental Sensor Data

Aggregating audio files and sensor recordings from the Karawatha Peri-Urban SuperSite, an eucalypt forest in Australia, collected between 2012 and 2018. Recordings were scheduled for 12 hours per day, split between dawn and dusk periods to capture bird choruses. The data includes long-term spectrograms for each audio file and sensor measurements of temperature and sound pressure levels.

Use Cases

• Analyze daily and seasonal patterns in bird chorus activity using the dawn and dusk audio recordings.
• Correlate temperature sensor data with acoustic activity levels to study environmental influences on soundscapes.
• Use generated long-term spectrograms for automated detection of specific bioacoustic events or species.
• Investigate changes in minimum, maximum, and mean sound pressure levels over the site's operational period from 2007 to 2018.

Strengths

• Data collection spanned multiple years, with recorders deployed in 2012 and 2014, providing longitudinal coverage.
• Recording strategy of 12 hours per day focused on biologically relevant dawn and dusk periods.
• Includes derived data products such as long-term spectrograms for each audio file to aid exploration.
• Sensor data captures complementary environmental variables like temperature alongside acoustic measurements.

Limitations

• The site was decommissioned in 2018, so the data is not updated and represents a closed historical period.
• Specific technical details like audio file count, recording resolution, or exact sensor specifications are not provided in the description.
• Data accessibility for bulk downloads requires following external instructions, which may add complexity.

Collection Method

Acoustic data collected via field recorders set up at the site, programmed to record 12 hours daily around dawn and dusk. Sensor data for temperature and sound pressure levels was also captured.

Time Range

Site established 2007, decommissioned 2018. Primary acoustic data collection initiated in 2012, with a second recorder deployed in 2014.

Freshness

The dataset metadata was last updated in March 2026, but the underlying data collection ended in 2018.
