The ocean is full of sounds that are generated from geophysical events, marine animals, and human activities. Listening to underwater sounds allows us to remotely acquire ecological data of marine biodiversity and investigate the changes of biodiversity in response to climate change and anthropogenic development. This project aims to establish a large-scale soundscape monitoring network and characterize ecosystem-specific soundscapes. Data available on the depositar are acoustic indicators describing soundscape dynamics, biological activity, and anthropogenic noise interference. Links to raw acoustic data and analysis codes are also available.
