In a world first, scientists have created digital 3D maps of the entire Great Barrier Reef. 

James Cook University researchers were among the scientists to work with German company EOMAP to map the 350,000 sq km of the Great Barrier Reef World Heritage Area and Torres Strait, providing not only more detailed individual reef data, but also a complete picture of Earth’s largest coral reef ecosystem.

The images were created using high-resolution, satellite-derived depth (bathymetry) techniques. 

JCU's Dr Robert Beaman said it's different to anything else available. Before these maps, nearly half of the shallow water reef area on the Great Barrier Reef had not been mapped using modern digital surveys.

While these coral reefs are the most ecologically significant, they are also the most difficult to map due to being either too remote or because of their shallow nature, which makes them navigationally dangerous.

According to EOMAP, the digital maps are a critical step towards identifying, managing and essentially preserving and protecting what lies within the waters of this global icon. Dr Beaman said the maps will help researchers manage threats to the reef, like crown of thorns starfish.

The mapping project is the largest of its kind ever conducted in Australia, and possibly the world.
