This sub-facility manages the IMOS Passive Acoustic Observatories, each of which consists of two to four moored hydrophones and noise loggers. The noise loggers record sound emitted by natural processes in the ocean and sources of biological origin, such as marine mammals, crustaceans and fish, which have unique acoustic signatures. Through an analysis of these signals, it is possible to discriminate and identify different species and to assess the number of animals present within the range of acoustic observation, which can then be linked to ocean productivity. Large animals can also be located by a horizontal array of sea noise loggers constituting a passive acoustic observatory. IMOS operated acoustic observatories at four sites: 1) Perth Canyon in Western Australia, 2) off Portland in South Australia, 3) near Tuncurry (Forster) in New South Wales, and 4) west of Kangaroo Island in South Australia (these sites were decommissioned in 2017/2018). From 2012 - 2015 the following two sites were sampled, with the support of the West Australian Government: 1) near the Kimberley Coast in Western Australia, and 2) near the Pilbara Coast in Western Australia.

该分设施管理IMOS被动声学观测站，每个观测站由两到四个系泊水听器和噪声记录器组成。噪音记录仪记录海洋自然过程和海洋哺乳动物、甲壳类动物和鱼类等生物源发出的声音，这些生物源具有独特的声学特征。通过对这些信号的分析，可以区分和确定不同的物种，并评估声学观测范围内的动物数量，然后将其与海洋生产力联系起来。大型动物也可以通过水平阵列的海洋噪音记录仪定位，这些记录仪构成被动声学观测台。IMOS在四个地点运营声学观测站：1）西澳大利亚州的珀斯峡谷，2）南澳的波特兰，3）新南威尔士州的通库里（福斯特）附近，以及4）南澳的袋鼠岛以西（这些地点于2017/2018年退役）。从2012年到2015年，在西澳大利亚州政府的支持下，对以下两个地点进行了采样：1）西澳大利亚州金伯利海岸附近，2）西澳大利亚州皮尔巴拉海岸附近。
