Massive 500 metres coral reef structure discovered off Australia

1 month ago 32

While coral reefs across the globe remain under threat as a result of the climate crisis, a team of scientists have discovered a truly rare find. The Australian Research Council (ARC) Centres of Excellence for Coral Reef Studies announced that a massive detached coral reef 500 metres high – taller than the Empire State Building – was found just off Cape York on the Great Barrier Reef.

The reef was discovered while mapping the northern Great Barrier Reef seabed from aboard the Schmidt Ocean Institute’s research vessel Falkor.

The base of the reef is approximately 1.5km wide and then rises to 500 metres at its shallowest depth, which is just 40 metres below the sea surface. This is the first detached reef found in almost 120 years, according to Dr Tom Bridge, a principal investigator of the expedition.

“This newly discovered detached reef adds to the seven other tall detached reefs in the area – all otherwise mapped in the late 1800s,” he said.

‘New oceanscapes are opening to us’

According to Wendy Schmidt, co-founder of Schmidt Ocean Institute, there are still many unknown structures and species within our oceans.

“The state of our knowledge about what’s in the ocean has long been so limited,” she said. “Thanks to new technologies that work as our eyes, ears and hands in the deep ocean, we have the capacity to explore like never before. New oceanscapes are opening to us, revealing the ecosystems and diverse life forms that share the planet with us.”

The Falkor vessel is currently on a 12-month exploration of the ocean surrounding Australia, with scientists looking to probe and map the depths of the northern Great Barrier Reef until mid-November.

Earlier this year, researchers from the University of Southampton found coral that, instead of going white as a result of rising ocean temperatures, emits a dazzling range of bright neon colours.

It was determined this was the result of coral ‘sunscreen’ that it creates, possibly to encourage algae vital to its survival to return.
