Coral reefs are some of the most stunning ecosystems on Earth. Even though they cover just 1% of our oceans, they’re home to 25% of all marine species and provide food, livelihoods, and protection to about 500 million people worldwide. Unfortunately, climate change has been taking its toll on these vital treasures. Protecting reefs requires accurate and consistent habitat maps, but creating a single map that captures all their intricate details is no small task. Until now, no consistent global map has existed to show key features like geomorphic zones (such as slopes, flats, or rims) or bottom compositions (like coral, algae, or sand).
That’s where the Global Coral Reef Mapping Project steps in. This innovative effort, led by the Remote Sensing Research Centre (RSRC), aims to fill this gap by producing detailed maps of coral reefs around the world. How? By using cutting-edge technology and a cloud-based mapping and modeling system. The project builds on years of RSRC’s research on the Great Barrier Reef and other reefs in the Asia-Pacific region. It takes things up a notch by incorporating high-resolution Planet Dove satellite images to refine the mapping process. These maps are being created region by region on a global scale, offering a consistent and precise view of coral reef habitats worldwide.
The project is a true team effort. It’s powered by an incredible partnership that brings together experts and support from around the globe. Here are the key players:
- Paul G. Allen Philanthropies provided funding, support, and leadership in development, communication, and management.
- Planet contributes global satellite imagery and processing capabilities.
- The Carnegie Institution/Arizona State University developed water column corrections and monitoring protocols.
- The National Geographic Society leads global engagement and verification efforts.
- RSRC handles the core mapping process.
All this hard work comes together in the Allen Coral Atlas, where you can find the maps and learn more about the project’s discoveries.
How it Works
The mapping approach uses advanced object-based image analysis combined with ecological modeling. This method has been developed and fine-tuned through previous studies on coral reef habitats. For example, earlier research looked closely at reefs in the Great Barrier Reef and beyond, providing a strong foundation for the global mapping initiative. By leveraging high-resolution satellite imagery and advanced technology, this project is taking reef mapping to the next level.
Who’s Behind the Project?
This monumental work wouldn’t be possible without a talented team of researchers and collaborators. Leading the charge are Chris Roelfsema, Stuart Phinn, Eva Kovacs, Mitchell Lyons, Nick Murray, Emma Kennedy, Kat Markey, Rodney Borrego-Acevedo, Daniel Harris, Doddy Yuwono, and Atefeh Sansoleimani. They’re joined by partner researchers like Greg Asner (Carnegie Institution/Arizona State University), Helen Fox (National Geographic Society), Kirk Larsen (Vulcan), and Andrew Zolli (Planet).
Where It’s Happening
This project spans the globe, focusing on coral reefs wherever they’re found. From the vibrant reefs of the Pacific to the hidden treasures of the Indian Ocean, it’s a worldwide effort to understand and protect these ecosystems better.
Why It Matters
By creating detailed and accessible maps, the project aims to support conservation efforts and help communities, scientists, and policymakers protect our planet’s coral reefs. The maps provide critical insights into how reefs are changing, which areas need urgent help, and how best to manage these delicate ecosystems for the future.
Coral reefs are vital to the health of our planet, and this project brings the world one step closer to ensuring they thrive for generations to come. Want to discover more? Check out the Allen Coral Atlas and explore these groundbreaking maps yourself!
