Tracking Ocean Life: New Insights from Australia’s Expanded Marine Acoustic Network
Scientists have achieved a significant breakthrough in tracking marine life along the eastern coast of Australia, thanks to the expansion of a vast network of underwater listening stations, or acoustic receivers, in Queensland waters. This initiative, known as the Integrated Marine Observing System (IMOS) Acoustic Telemetry Array Project, has revealed unprecedented insights into the movements of key species, including sharks, rays, and commercially important fish.
The expanded network consists of 119 new acoustic receivers placed in mainly coastal locations, spanning over 2,100 kilometers from the Gold Coast to remote far north Queensland. These additions complement the 208 receivers already in place, enhancing the detection of priority species. Combined with existing infrastructure in neighboring states, the receiver coverage along the east coast of Australia now spans nearly 4,000 kilometers.
Aggregate Efforts for Shark Detection
Since the installation of the Queensland IMOS Acoustic Telemetry Array in 2019, scientists have observed a bull shark tagged in Sydney, New South Wales, at the northern limit of the new array in far north Queensland—a remarkable 2,900 kilometers away. Previously, the longest recorded movement for bull sharks was approximately 1,770 kilometers, from Sydney Harbor to reefs off Townsville, Queensland. This data is crucial for improving beach safety and understanding the behavior and distribution of these species, comparable to how researchers in the Gulf of Mexico track Gulf sharks.
Several bull sharks were detected making repeated long-distance movements between states along the coast during the three years the expanded array has been in operation. This information not only helps in monitoring and protecting marine species but also assists in marine park management. The data collected can help managers understand where animals move within and away from marine park boundaries, providing greater insights into the movement patterns of highly mobile species of high human and conservation interest.
“In the future, we can see the data helping managers understand where animals move within and away from marine park protected area boundaries, and provide greater insights into the movement patterns of highly mobile species of high human and conservation interest,”
said Dr. Leanne Currey-Randall, a project leader from Australian Institute of Marine Science (AIMS).
Large-Scale Data Collection
The acoustic telemetry array uses strategically placed underwater receivers to record data when a tagged animal swims within detection range. Each receiver captures the unique transmitter identification number, date, and time stamp, helping researchers map the movement patterns of 812 animals tagged by the project, as well as those tagged by partner groups. This extensive data collection underscores the importance of continuous monitoring, similar to how the NOAA Fisheries service tracks marine life in U.S. waters.
Dr. Currey-Randall highlighted that the enhanced array is a collaborative effort between James Cook University, IMOS, and Queensland’s Shark Control Program, along with a diverse group of collaborators from government, science, industry, and tourism sectors. This partnership has not only delivered beneficial data but has also forged new relationships to support future initiatives. This approach mirrors successful coastal management initiatives in the U.S.
Study lead author Adam Barnett from James Cook University and the Biopixel Oceans Foundation emphasized the importance of collaborations with existing and new programs and partners. He stated, “”Collaborations with existing and new programs and partners resulted in an impressive effort to install and maintain the receivers. This has delivered beneficial data for us all and forged new relationships that we hope will assist with future projects.”
Study co-author Dr. Fabrice Jaine from IMOS said, “The expanded animal tracking infrastructure is providing fascinating new insights into movements of marine species at continental scales, and with an unprecedented level of detail. This would not be possible without vibrant collaboration between numerous research groups from Queensland and beyond, and the diverse operational partners who help make these efforts possible.”

Frequently Asked Questions
1. What is the Integrated Marine Observing System (IMOS) Acoustic Telemetry Array project?
The IMOS Acoustic Telemetry Array Project is an initiative in Queensland waters that utilizes a network of underwater listening stations, also known as acoustic receivers, to track marine life along the eastern coast of Australia. The project has expanded it’s network, improving detection and understanding of key marine species, including sharks, rays, and commercially significant fish.
2. How has the Australian marine acoustic network expanded, and why is it significant?
The network now includes 119 new acoustic receivers placed along the coast from the Gold Coast to far north Queensland, adding to the existing 208 receivers. This expansion extends the receiver coverage along the east coast of Australia to nearly 4,000 kilometers. The network enhancement is significant as it provides critical data on the movements of marine species, aiding in conservation efforts and marine park management.
3. What breakthrough insights have been achieved through the expanded network?
One of the breakthroughs is the tracking of a bull shark from Sydney, NSW, to far north Queensland, covering a remarkable distance of 2,900 kilometers. This observation extends previous records of long-distance shark movement from Sydney Harbor to reefs off Townsville, Queensland, and is crucial for understanding marine species’ behaviors and distribution.
4. How does the expanded array contribute to marine park management?
The data collected from the expanded array helps managers understand the movement patterns of marine species within and across marine park boundaries.This information is crucial for protecting highly mobile species that are of high human and conservation interest. The data can be used to improve the safety of beaches and enhance conservation strategies for marine species.
5. What collaborative efforts support the acoustic telemetry project?
The project is a collaborative effort involving James Cook University,IMOS,Queensland’s Shark Control Program,and various government,scientific,industrial,and tourism partners. This collaboration not only delivers valuable data but also helps forge new relationships that support future conservation initiatives.
6. How does large-scale data collection from acoustic receivers benefit marine research?
The acoustic telemetry array records data such as transmitter identification numbers, dates, and timestamps when tagged animals are within detection range. This detailed data collection involves mapping the movement patterns of 812 animals, which underlines the importance of continuous monitoring similar to initiatives like NOAA Fisheries in the U.S.
7. What future prospects does the expanded marine acoustic network offer?
According to experts like Dr. Leanne Currey-Randall from AIMS, the continued gathering of data will help refine our understanding of marine species’ movements and inform marine park boundary management. The innovations in acoustic telemetry provide models and frameworks that can be emulated by coastal governments globally.
8.How is collaboration facilitating the success of marine acoustic tracking?
Study lead author Adam Barnett and dr. Fabrice Jaine from IMOS highlight the vital role of collaboration among multiple research groups and partners from Queensland and beyond.
