Scientists explore blue hole in Great Barrier Reef
A blue hole that is extremely hard to get to, nestled off Daydream Island of the great Barrier Reef, has finally been explored by scientists. The blue hole was previously described by geologists, but due to its location, had never been explored. Although the researchers were only able to reach 65 feet deep, they were able to surmise that the blue hole may even be older than the famed Belize blue hole. Scientist Johnny Gaskell led the expedition.
