Based on military grade ceramics, THURN's Passive Acoustic Monitoring hydrophones enable listening to underwater ecosystems in unprecedented detail. Suitable for long-term deployment in both freshwater and marine environments, these high quality aquatic microphones provide the heart of a Passive Acoustic Monitoring system which can be used to record and analyse biodiversity and ecosystem health over time. This can be particularly useful for quantifying how habitats respond to events such as extreme weather, flooding, pollution and climate change as well as construction and infrastructure works.
