Sailors find pumice "raft" the size of Washington D.C., which floats in the Pacific and could help restore the Great Barrier Reef

  • The huge floating stone raft was created earlier this month by an underwater volcano near Tonga.
  • Sailors reported being surrounded by pumice as far as the eye can see.
  • The pumice stone could carry millions of coral that could replenish the Great Barrier Reef.

A giant pumice raft, which was created by an underwater volcano, swims towards Australia and could help the Great Barrier Reef to recover from the bleach.

The pumice raft is approximately 60 square kilometers ̵

1; nearly as large as Washington DC scientists reported earlier this month due to an underwater volcano near Tonga, about 2,000 miles east of Brisbane, Australia, in the South Pacific. [19659007] According to the Smithsonian Institution's Global Volcanism Program, sailors first encountered the giant stone raft on August 9 . The purser on a small ship reported, as far as she could see, surrounded by pumice stone. She said the surface was about one foot deep and contained pieces that were larger than 30 inches in diameter.

The Australian couple Michael Hoult and Larissa Brill struck the raft when They sailed on a catamaran to Fiji on 16 August reported the Guardian.

"We have entered a total debris from pimples of marble to basketball size," the couple wrote in a Facebook post.

"Actually it was pretty scary "Brill later told CNN." The whole ocean was dull – we could not see the water reflection of the moon. "

Hoult said," The rocks closed around us, so we we could not see our lane or our wake, we could only see the rim where there was normal water again at night – shiny water. "

While this island of stone hikes to Australia, harbors She's Countless Marine Animals said the geologist of Queensland University of Technology Scott Bryan of the Australian Broadcasting Corporation.

"There are probably billions to billions of pieces of pumice floating all together and every piece of pumice stone is a vehicle for a marine organism," Bryan said. "If it does arrive here, it will be covered with a number of algae and barnacles, corals, crabs, snails and worms."

The millions of individual corals have the potential to find a new home along the Australian coast.

The pumice "is a natural mechanism for species that settle, replenish, and grow into a new environment," he said. "It's just one way how nature can promote regeneration."

Bryan told The Guardian.

Heatwaves in 2016 and 2017 caused devastating coral bleaching and dies over two-thirds of the Great Barrier Reef off.

Coral bleaching occurs when warm water expels coral Zooxanthella algae living in their tissues. This will make the coral white. Bleaching puts more strain on the coral and is more likely to die.

Bryan said pumice pieces should appear on the Australian coast in seven to twelve months.
