Brief description
This dataset contains audio files for Karawatha Peri-Urban SuperSite. Karawatha Peri-Urban SuperSite was established in 2007 and decommissioned in 2018. The site was located in eucalypt forest at Karawatha Forest. For additional site information, see Karawatha Peri-Urban SuperSite
A recorder was initially set up for three months in 2012 to collect acoustic data across different plots within the site. A second recorder was set up in 2014. This collected audio data for a total of 12 hours per day, split between six hours around dawn and six hours around dusk. The recording schedule aimed at capturing morning and evening bird choruses while minimizing memory and battery requirements. A long-term spectrogram has been generated for each audio file to aid in data exploration. The sensor also recorded temperature, minimum- maximum- and mean-sound pressure levels.

Lineage
The first acoustic sensor set up for three months in 2012 to collect acoustic data across different plots within the site. This sensor recorded wav files that were later converted into flac format. The files were dual channel, had a samplig rate of 44,100 Hz and a depth of 16 bit. Limited metadata information are available for these recordings.
The second acoustic sensor was set up to collect audio data as part of a continent wide long term monitoring project. The sensor was a Wildlife Acoustics Song Meter 2 equipped with two microphones. According to manufacturer's specifications the microphones sensitivity was -11±4 dB (0 dB=1 V/Pa at 1 kHz). The sensor was mounted on a star picket. Data were recorded for a total of 12 hours per day, split between six hours around dawn and six hours around dusk. Recordings were made as dual channel, three-hour long wac files, and were later converted into flac format. They had a sampling rate of 24,000 or 48,000 Hz and a depth of 16 bits.
Long-term spectrograms have been created for the audio files and are avaialble through the data link.
The sensor also recorded 'ancillary data' such as temperature, minimum- maximum- and mean-sound pressure levels.
Notes
CreditWe at TERN acknowledge the Traditional Owners and Custodians throughout Australia, New Zealand and all nations. We honour their profound connections to land, water, biodiversity and culture and pay our respects to their Elders past, present and emerging.
Karawatha Forest Park is managed by the Brisbane City Council.
This work was funded by the Terrestrial Ecosystem Research Network (TERN), an Australian Government National Collaborative Research Infrastructure Strategy (NCRIS) project.
Long-term acoustic recordings are collected to characterise the acoustic sources in the ecosystem. Recordings can be used to estimate biodiversity, monitor temporal changes in the soundscape, compare the acoustic characteristics of different locations, and assess the effect of particular events such as bushfires and floods.
