Integrated Marine Observing System (IMOS), the Australian Animal Acoustic Telemetry Database is a centralized repository with a web-interface that facilitates marine acoustic data and metadata uploads, annotations, and access. The large network of acoustic receivers in waters around Australia allows the detection of tagged animals, and provides a tool for observing animal movements in coastal and continental shelf environments. This database serves as a central public repository for the Australian research community, facilitating regional to national-scale collaboration and supporting the management of marine resources.
