Samford Peri-Urban Acoustic Recordings with Environmental Sensor Data

Containing acoustic recordings from the Samford Peri-Urban SuperSite in Australia, collected for 12 hours daily around dawn and dusk. The data includes generated long-term spectrograms, acoustic indices, false-color spectrograms, and sensor-recorded temperature and sound pressure levels. Recordings were made between October 2011 and 2013.

Use Cases

• Analyze acoustic indices to characterize the soundscape and monitor temporal environmental changes in the eucalypt forest.
• Use false-color spectrograms to identify and navigate to specific sound sources like bird choruses or insect activity.
• Correlate temperature sensor data with acoustic energy distribution to study environmental influences on soundscapes.
• Apply long-term spectrograms for data exploration and to assess trends in fauna biodiversity over the recording period.

Strengths

• Recordings capture 12 hours of audio per day, split between dawn and dusk periods to target biological activity.
• Data includes multiple derived analytical products like acoustic indices and false-color spectrograms.
• Sensor data includes temperature and sound pressure level measurements alongside audio.

Limitations

• The temporal coverage is limited to specific periods between 2011 and 2013, not a continuous long-term series.
• The dataset's size, row count, and specific file formats beyond HTML and PNG are unknown.
• Recordings are from a single geographic location, limiting generalizability to other ecosystems.
