Litchfield Savanna Acoustic Data Collection - TERN

<p>This dataset contains audio files for Litchfield Savanna SuperSite. Litchfield Savanna SuperSite was established in 2013 in Litchfield National Park. Site selection was influenced by the history of long-term monitoring work undertaken in this area by the Darwin Centre for Bushfire Research (formerly Bushfires NT). The core 1 ha plot is dominated by <em>Eucalyptus miniata</em> and <em>Eucalyptus tetrodonta</em>. The site is representative of the dominant ecosystem type across northern Australia: frequently burnt tropical savanna in high rainfall areas. For additional site information, see <a href=" https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/litchfield-savanna-supersite ">Litchfield Savanna SuperSite</a></p>


<p>In 2015 an acoustic recorder was set up on the main flux tower. In 2016 a second record was set up on mini tower N.&nbsp;5. The two recorders 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 sensors also recorded temperature, minimum- maximum- and mean-sound pressure levels.</p>

Purpose
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.

Statement
<p>Two acoustic sensors were set up to collect audio data as part of a continent wide long term monitoring project. The sensors were Wildlife Acoustics Song Meter 2. Each sensor had two microphones. According to manufacturer's specifications the microphones sensitivity was -36&plusmn;4&nbsp;dB (0&nbsp;dB=1&nbsp;V/Pa at 1&nbsp;kHz). One sensor was mounted on the main flux tower, while the other was mounted on mini tower N.&nbsp;5. 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 22,050&nbsp;Hz or 44,100&nbsp;Hz and a depth of 16&nbsp;bits. Long-term spectrograms have been created for the audio files and are avaialble through the data link.</p> <p>The sensors also recorded 'ancillary data' such as temperature, minimum- maximum- and mean-sound pressure levels.</p>
