Scientists from the Schmidt Ocean Institute team have made a new discovery, a massive detached coral reef in the Great Barrier Reef–the first to be discovered in over 120 years. The towering reef measures more than 500m high–taller than the Empire State Building!
The reef was first found on Oct. 20, as a team of scientists led by Dr. Robin Beaman from James Cook University was conducting underwater mapping of the northern Great Barrier Reef seafloor. The team then conducted a dive on Oct. 25 using Schmidt Ocean Institute’s underwater robot SuBastian to explore the new reef.
The dive was live-streamed, with the high-resolution footage viewed for the first time and broadcast on Schmidt Ocean Institute’s website and YouTube channel.
The base of the blade-like reef is 1.5km-wide, then rises 500m to its shallowest depth of only 40m below the sea surface. This newly discovered detached reef adds to the seven other tall detached reefs in the area, mapped since the late 1800s, including the reef at Raine Island–the world’s most important green sea turtle nesting area.
“This unexpected discovery affirms that we continue to find unknown structures and new species in our Ocean,” said Wendy Schmidt, co-founder of Schmidt Ocean Institute. “The state of our knowledge about what’s in the Ocean has long been so limited. 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.”
“We are surprised and elated by what we have found,” said Dr. Beaman. “To not only 3D map the reef in detail, but also visually see this discovery with SuBastian is incredible. This has only been made possible by the commitment of Schmidt Ocean Institute to grant ship time to Australia’s scientists.”
The discovery of this new coral reef adds to a year of underwater discoveries by Schmidt Ocean Institute. In April, scientists discovered the longest recorded sea creature–a 45m siphonophore in Ningaloo Canyon, plus up to 30 new species. In August, scientists discovered five undescribed species of black coral and sponges and recorded Australia’s first observation of rare scorpionfish in the Coral Sea and Great Barrier Reef Marine Parks.
