Scientists from James Cook University, the University of Granada and the University of Sydney made the discovery while working from a research ship around 75 km (46 mi) off the coast. The team was mapping the floor in an area called the Queensland Trough using 3D multibeam mapping, a technique that bounces sound waves off the seabed to determine water depth, and made some unexpected discoveries.

“We were amazed to discover this cluster of knolls while 3D multibeam mapping the deep Great Barrier Reef seafloor…
