Australian scientists found a detached coral reef on the Great Barrier Reef that exceeds the height of the Empire State Building and the Eiffel Tower, the Schmidt Ocean Institute said this week, the first such discovery in over 100 years.
The “blade like” reef is nearly 500 meters tall and 1.5 kilometers wide, said the institute founded by ex-Google boss Eric Schmidt and his wife Wendy. It lies 40 meters below the ocean surface and about six kilometers from the edge of Great Barrier Reef.
