Innovative System Aims to Monitor Coral Reefs in Real-Time
A team of Australian researchers is in the process of creating a comprehensive, real-time monitoring system aimed at protecting coral reefs across the globe, particularly addressing the critical issue of coral bleaching linked to global warming.
Coral reefs are facing a dire situation, with reports indicating that 75% of reefs worldwide have suffered from bleaching due to elevated water temperatures over the past two years.
The Great Barrier Reef (GBR), a UNESCO World Heritage site and one of the most vital ecological and tourism assets in Australia, has notably suffered from catastrophic bleaching events since 2016. The situation has been worsened by outbreaks of crown-of-thorns starfish and various coastal development activities.
In response to this crisis, a joint initiative led by the University of South Australia (UniSA) is bringing together researchers from Queensland and Victoria. This project focuses on combining advanced remote sensing technologies with machine learning, artificial intelligence, and Geographic Information Systems (GIS) to create a robust monitoring framework aimed at preserving the planet’s vulnerable marine ecosystems.
This innovative platform will synthesize research data pertaining to coral reefs into a single dashboard that facilitates real-time global monitoring. Centralized information will encompass a range of resources, such as underwater videos, photographs, satellite imagery, textual files, and time-sensitive environmental readings.
Dr. Abdullahi Chowdhury, the lead data analyst for UniSA, highlights the importance of unifying the various factors impacting coral health. “Currently, we operate separate models that provide extensive data on various aspects of reef vitality—such as bleaching frequency, disease occurrences, juvenile coral populations, and fish species abundance. However, these datasets are kept in isolation,” remarks Dr. Chowdhury.
“This fragmented approach makes it difficult to grasp the overall health of reefs or to engage in large-scale, real-time assessments,” he adds.
The research team’s integrated system aims to monitor the severity of bleaching over time, track the population dynamics of crown-of-thorns starfish, signal disease outbreaks, and evaluate juvenile coral levels as well as reef fish diversity, size, and biomass. Musfera Jahan, a GIS data expert and PhD candidate from Central Queensland University, emphasizes the benefits of this centralized approach: “By aggregating real-time data, we can develop predictive models that enhance conservation efforts and prompt timely interventions.”
“Our coral ecosystems are deteriorating rapidly due to climate change—not only in Australia but globally. Immediate and decisive action is required,” Ms. Jahan asserts.
Often likened to the “rainforests of the sea,” coral reefs occupy merely 1% of the Earth’s ocean territory yet harbor approximately 25% of all marine life.
This advanced monitoring technology will compile data from esteemed organizations, including the National Oceanic and Atmospheric Administration (NOAA), the Monterey Bay Aquarium Research Institute (MBARI), the Hawaii Undersea Research Laboratory (HURL), and Australia’s own CSIRO.
The collaborative efforts behind this initiative underscore a crucial message: the future of coral reef conservation hinges on the synergy of technological advances and collective action. “This research outlines a strategic framework for leveraging technology to safeguard the longevity of coral reefs for future generations,” the team concludes.
