Outline of Final Research Achievements

Soundscapes, which are composited by sounds of biological, environmental, and anthropogenic sources, have been considered as a remote sensing platform to monitor marine ecosystems. This project aims to facilitate the assessment of the spatial-temporal dynamics of marine ecosystems via soundscape information retrieval (SIR). During the project period, we developed techniques for audio visualization, source separation, and event identification. Long-duration recordings were collected from algal reefs, continental shelves, coral reefs, estuaries, and deep-sea environments. On the basis of SIR, single-channel audio can be transformed into multiple ecological dimensions, including the changes of acoustic environment, biodiversity, and anthropogenic interference. This project also enables the "Ocean Biodiversity Listening Project" and will further contribute a large amount of acoustic data for researchers who interest in using soundscape information for ecosystem monitoring.

Academic Significance and Societal Importance of the Research Achievements

Listening to natural sounds allows us to remotely acquire data of biodiversity and investigate the changes in response to human development. The outcome can help managers and stakeholders to use soundscapes in the ecosystem assessment and improve the decision making of conservation management.
