Australian scientists discover huge new coral reef
The 'blade-like' reef is nearly 500 metres tall and 1.5 kilometres wide
Australian scientists found a detached coral reef near the Great Barrier Reef that exceeds the height of the Empire State Building and the Eiffel Tower, the Schmidt Ocean Institute said this week.
It is the first such discovery in more than 100 years.
The "blade-like" reef is about 500 metres tall and 1.5 kilometres wide, the institute, founded by former Google chief executive Eric Schmidt and his wife Wendy, said.
It lies 40 metres below the ocean surface and about six kilometres from the edge of the Great Barrier Reef.
A team of scientists from James Cook University, led by Dr Robin Beaman, were mapping the northern sea floor of the Great Barrier Reef on board the institute’s research vessel Falkor, when they found the reef on October 20.
"We are surprised and elated by what we have found," Dr Beaman said.
To not only 3D map the reef in detail, but also visually see this discovery with SuBastian is incredible

He said it was the first detached reef of that size to be discovered in more than 120 years and that it was thriving with a "blizzard of fish" in a healthy ecosystem.
The discovery comes after a study this month found the Great Barrier Reef had lost more than half its coral in the past three decades.
Using an underwater robot known as SuBastian, the scientists filmed their exploration of the new reef, collecting marine samples on the way, which will be archived and placed in the Queensland Museum and the Museum of Tropical Queensland.
"To not only 3D map the reef in detail, but also visually see this discovery with SuBastian is incredible," Dr Beaman said.
Although the northern section of the Great Barrier Reef suffered from bleaching in 2016, Dr Beaman said this detached reef did not display any evidence of damage.
Bleaching occurs when the water is too warm, forcing coral to expel living algae and causing it to calcify and turn white.
The Great Barrier Reef runs 2,300km down Australia's north-east coast, spanning an area half the size of Texas.
It was inscribed as an Unesco world heritage site in 1981 and is the most extensive and spectacular coral reef ecosystem on the planet.
