The IMOS passive acoustics facility has made passive acoustic data from four sites around Australia publicly available since 2008 at one site, although funding now may cause a temporary pause. This document summarizes the facility. The operation of the IMOS facility could be considered a model for how passive acoustic data can be disseminated. One can go to https://acoustic.aodn.org.au/acoustic/, choose a deployment, an 18-day spectrogram will pop up and if one has the right browser, click somewhere and the nearest samples’ spectrogram and waveform pop up with an option to download the sample. It is easy, for example, to locate whales this way.
