Coral reefs support 500 million people and safeguard vulnerable coastal towns from storms, in addition to being home to some of the world’s most biodiverse ecosystems. However, coral bleaching due to rising global temperatures is a challenge that is critically affecting their ability to perform their part in the ecosystem. When heated, corals eject the symbiotic algae that dwell in their tissues and are responsible for their brilliant colors. When that happens, their white inner structure becomes visible. If they are bleached for a long time, the corals will ultimately perish. The Allen Coral Atlas was produced by Arizona State University (ASU) in collaboration with Vulcan Inc. to help keep corals alive.

ASU and Vulcan created a high-resolution mapping system in partnership with the University of Queensland, the National Geographic Society, and Planet to aid in the preservation of reef systems throughout the globe. The Allen Coral Atlas maps can illustrate changes among the world’s enormous reefs with pinpoint accuracy, down to a few square meters. The interactive map allows users to download habitat maps, satellite photos, and ocean depth data. Reef scientists and managers may use this data to identify dangers and develop new ways to mitigate risks.
Not only will global maps provide big-picture knowledge, but new technology will also allow for the detection of minute changes in reefs over time. Previously, scientists have concentrated on the aftermath of large-scale bleaching occurrences. Researchers will now be able to detect changes in the sediment layer before a disaster occurs. Potential hazards to reef ecosystems may be quickly identified and addressed, potentially saving these underwater environments. Robotics, artificial intelligence, and more satellites will be among the Atlas technology’s future uses, which will help to enhance the platform’s capacity. The government of Sri Lanka has already utilized the Atlas to develop marine national parks and restore reefs. Other countries are yet to implement this, but if used correctly, then it will be a great initiative.
