Researchers from the United States and Australia studied the seabed off the coast of Cape York, an island in northern Queensland.
The reef rises above the rest of the bottom like a wedge: its width is 1.5 kilometers, while at the top it narrows to 40 meters. The height of the structure is higher than the Eiffel Tower.
The researchers note that most of the reefs in the area were already mapped back in the late 1800s. The reef is now the seventh tallest formation on the Great Barrier Reef.
