Acoustic Telemetry Detections of Threatened River Sharks and Sawfish in Northern Australia

Acoustic telemetry data collected under the NERP and NESP Marine Biodiversity Hub projects. The database contains detection data from receiver arrays deployed in the Adelaide River and Alligator Rivers systems in northern Australia. It was published by the Australian Ocean Data Network and last updated in June 2026.

Use Cases

• Modeling movement patterns based on acoustic detection events.
• Assessing habitat use and residency in northern Australian rivers.
• Estimating natural mortality rates for threatened Glyphis and Pristis species.
• Supporting recovery management for listed and rare marine species.

Strengths

• Data is part of two major Australian environmental research programs (NERP and NESP).
• Includes both raw and processed (cleaned) detection data.
• Receiver deployment metadata is available through the IMOS Animal Tracking Facility.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific river systems monitored.
